Using the P&T Control Knob, you must first
select the LED ON/OFF Button on the ventilator's screen, and then press the P&T Control Knob. The button on the screen
changes its appearance, so that it looks
“pressed”. It now performs its function
(turning the LED ON in this case). Sometimes you are told to “activate and set” a
field. In this case you first activate the field,
and then turn the P&T Control Knob to set a
value.

Deactivate LED ON/OFF.
With LED ON/OFF still selected and activated, you must press the P&T Control Knob
again. The button on the screen changes its
appearance, so that it looks “unpressed”. It
stops performing its function (turning the
LED OFF in this case).

above ambient pressure. If the patient pressure (Ppat) is 80 mbar, it means the pressure
is 80 mbar above the ambient (room) pressure.
Software version
0.6.0
The ventilator contains a memory device
that holds software identified by a version
number.
Update
This kit or software enables an upgrade to
implement a new function.
An update is an improvement to an existing
function. An update normally involves only
software. A software update is indicated by
an increment of the last digit of the three
digit software version number (e.g. 1.2.1 to
1.2.2).
Upgrade
This kit or software enables an upgrade to
implement a new function.
An upgrade is the addition of new functions
to a device. There are three ways to perform
an upgrade:
• Add a hardware item that offers additional functions.
• Upgrade to a higher software revision.
Depending on how important is the software upgrade, it is either marked by an
increment on the first or on the second
digit (e.g. 1.2.0 to 1.3.0 or 1.2.0 to

WARNING
Never attach a Spirometer or any other device or tube to the exhaust port of the Expiratory Valve. This will cause the ventilator to lose full control of PEEP/CPAP.
The Expiratory Valve enables gas to escape from the Patient Breathing Circuit in a controlled manner, allowing the patient to
exhale.
The Expiratory Valve:
• Maintains PEEP/CPAP if required - to do this, the action of the Expiratory Valve is closely synchronized with the action of
the Inspiratory Valve
• In Ambient State, the Expiratory Valve is open

3.7 Patient Flow Sensor Overview
The HAMILTON-C2 accurately measures flow, volume, and pressure in the patient’s airway with the Patient Flow Sensor.
The area of the orifice changes depending on the flow rate. It opens progressively as the flow increases, creating a pressure
drop across the orifice. The pressure difference is measured by a high-precision differential pressure sensor (Pflowsensor)
located on the Pressure Sensor Assembly inside the ventilator. The pressure difference varies with flow (relationship determined during flow sensor calibration), so the patient’s flow is determined from the pressure drop. The HAMILTON-C2 calculates volume from the flow measurements. The Patient Flow Sensor is highly accurate even in the presence of secretions,
moisture, and nebulized medications. The HAMILTON-C2 continuously flushes the sensing tubes with mixed gases (rinse
flow) to prevent blockage.

3.8 Oxygen Sensor Overview
WARNING
The ventilator should never be used for ventilating a patient without some means of monitoring the oxygen content in the
gas mixture delivered to the patient. The ventilator can not be operated without an Oxygen Sensor installed.
The Oxygen Sensor (A, see Figure 3-8 Oxygen Sensor Overview) is attached to the front left side of the ventilator behind the
Oxygen Sensor Cover (B, see Figure 3-8 Oxygen Sensor Overview). It is used to monitor the oxygen concentration in the gases
delivered to the patient. The Oxygen Sensor performs only a monitoring function, and can be disabled by the user, if
required.

Oxygen Sensor Cover
NOTICE
Hamilton Medical Oxygen Sensors are available from Hamilton Medical AG only.
The Hamilton Medical Oxygen Sensor produces a voltage between 11 and 13mV at 21% O2 which changes with oxygen
concentration. Each unit comprises a teflon-bonded gold cathode and a lead anode, submerged in a liquid electrolyte solution. When oxygen diffuses through the flouropolymer membrane, the electrochemical reduction of oxygen on the cathode
and the corresponding oxidation of the anode generates an electrical current that is proportional to the concentration of oxygen.

Pneumatics: Overview and Theory of Operation
3.9 Principal Gas Flow Overview
The ventilator regulates the flow of gases at three points, as represented in the Principal Gas Flow Diagram (see Figure 3-9
Principal Gas Flow Diagram).
The “Principal Gas Flow” is the flow of air and oxygen into the ventilator, out to the patient and directly at the Expiratory
Valve back to the room. Room air (A) is aspirated, mixed with compressed oxygen (C) from an external high or low pressure
supply (B) and compressed in the Blower Module (D). This flow of the air/oxygen mixture is managed by components that
regulate the gases at three points:
• Room air and oxygen mixture in the Blower Module (D regulation point 1).
• Room air and oxygen mixture through the Inspiratory Valve and Patient Flow Sensor (E - regulation point 2).
• Expired gas from the patient through the Expiratory Valve (F - regulation point 3).
Expired gases from the patient are allowed to escape into the room.
The following sections provides details of the components that manage the “Principal Gas Flow”.

3.9.3 Components for the Ambient State Gas Flow
If there is a total breakdown of ventilation, the ventilator goes into Ambient State.
In the Ambient State, the Ambient Valve is unpowered, allowing the patient to inspire ambient air through the Ambient
Valve Sealing Membrane.
In the Ambient State, the Expiratory Valve is also unpowered, enabling gas to escape from the Patient Breathing Circuit in a
controlled manner, allowing the patient to exhale into the room. The Expiratory Valve Sealing Membrane has a one-way flow
from the Patient Breathing Circuit.
The one-way function of the Expiratory Valve make sure the patient does not inhale his exhaled CO2 (rebreathing).

If the pressure from the Inspiratory Valve for the Patient Breathing Circuit is too high (15 mbar above Pmax), the Ambient
Valve is driven to an open position to relieve the excess pressure to the room.
It also functions as an additional backup to the pressure limit set by the user for the Patient Breathing Circuit.

3.9.5 Components for the Nebulizer Gas Flow
The ventilator provides oxygen with sufficient pressure to drive the Nebulizer Jar. The oxygen flow is reduced to approximately 8 liters/minute by means of an internal flow restrictor in the Oxygen Mixer Block Assembly. A valve attached to the
Oxygen Mixer Block Assembly switches the flow of oxygen to the Nebulizer Jar through the output connection at the Front
Panel. The pneumatic nebulizer is inactive when low pressure oxygen is used.

Pneumatics: Overview and Theory of Operation
3.10 Ventilation Control Principle
The HAMILTON-C2 is a pressure controlled ventilator. This means that the applied volume is controlled by a specific calculated pressure and not by a fixed, permanent volume only. The HAMILTON-C2 does not contain a tank. The required pressure
is generated by a turbine, known as a Blower Module, which turns at approximately 35'000 RPM during normal ventilation.
This pressure source provides a pressure that is always at least 10 mbar above the required ventilation pressure, e.g. PEEP +
Pcontrol + 10 mbar = Pblower. To get the pressure in the Patient Breathing Circuit, the outlet pressure of the Inspiratory
Valve is measured 1000 times per second, so the Expiratory Valve can react within a fraction of a second.
On the other hand, the Expiratory Valve manages the outflow of the gas. It applies a known force to the membrane which
has a direct effect on the gas in the Patient Breathing Circuit (back pressure). It never completely closes the outlet of the
Patient Breathing Circuit during ventilation, so the membrane is floating all the time.
The correct ventilation pressure is given by the close collaboration of the Inspiratory Valve, that applies the pressure into the
Patient Breathing Circuit and the Expiratory Valve that stabilizes it by a controlled release of the gas.

3.11 Gas Rinse Flows
The rinse flow is provided on the blower side of the Inspiratory Block Assembly. A constant small flow of gas (approximately
11.5 ml/min at 35 mbar blower pressure) is provided through both tubes to the Patient Flow Sensor. The difference between
the Proximal and Distal Rinse Flows are ±10%. The rinse flow eliminates the possibility of contamination from the patient,
condensing humidity in the measuring tubes and cross-contamination to other patients.

Pneumatics: Overview and Theory of Operation
3.13 Components that Measure Gas Flow and Pressure
The Qvent Flow Sensor measures the flow of Air/Oxygen in the Patient Breathing Circuit. The Pvent_control measurement is
used to control the Inspiratory Valve. The Pvent_monitor Sensor measures the pressure in the Patient Breathing Circuit.
During normal ventilation, the Flow Sensor Autozero Valves open at calculated intervals to expose the Pflowsensor Pressure
Sensor to ambient air for the Autozero offset compensation.

NOTICE
During the Autozero procedure, which occurs in a fraction of a second, the patient is ventilated normally. Since parameters
such as expired tidal volume, resistance, compliance, and PEEP cannot be measured or monitored, the ventilator uses the
most recently measured values until the procedure is complete.

5.1 Rechargeable Lithium Ion Battery
WARNING
It is mandatory that the HAMILTON-C2 is operated with at least one battery installed.
NOTICE
• At high operating temperature, the battery does not start charging. For example after transport and high temperature.
• The backup battery is intended for short-term use only. It is not intended to be a primary power source.
• Hamilton Medical recommends that the ventilators batteries be fully charged before you ventilate a patient. If the batteries are not fully charged and the AC power fails, always pay close attention to the level of battery charge.
The Backup Battery provides backup power to the HAMILTON-C2.
5.1.1 Introduction
Two backup batteries, one standard and one optional, are used the HAMILTON-C2 when the primary power source is low or
unavailable.
When the primary power source (either AC mains power or a DC power supply) fails, the ventilator automatically switches to
backup battery operation with no interruption in ventilation. An alarm sounds to signal the switchover. To reset the alarm,
silence the alarm to confirm notification of the power system change.
If the optional battery (battery 2) is available and adequately charged, the ventilator switches to this battery first. When battery 2 is depleted or unavailable, the ventilator switches to the standard battery (battery 1).
The batteries power the ventilator until the primary power source is adequate or the battery is depleted.
As a further safeguard, the HAMILTON-C2 provides a low battery alarm. It also has a capacitor-driven backup buzzer that
sounds continuously for at least 2 minutes when battery power is completely lost.
The ventilator recharges the batteries whenever the ventilator is connected to either AC or >20VDC, with or without the
ventilator power switched on. The battery charge indicator (see Figure 5-1 Power Source Symbols and Battery Charge Indicator) lights to show that the batteries are being charged.
The power source symbols in the bottom right-hand corner of the screen show the available power sources. A frame around
a symbol indicates the current ventilator power source. Green indicates the level of battery charge.

Lithium Ion Battery
5.1.2 Replacing the Battery
WARNING
When a battery has reached its end-of-life, the capacity is reduced and the battery weakens. The use of a ventilator with
weak batteries can cause the device to report incorrect fuel gauge information, leading to a possible unexpected ventilation
stop if a power failure occurs.
The batteries are hot-swappable; that is, they can be replaced while the ventilator is operating. Replace with a newly charged
battery. For battery replacement refer to the Backup Battery Pack Removal/Assembly Section 10.4.1.
5.1.3 Storage Hints
• Never store a battery in a discharged state.
• Recharge batteries every 6 months.
• Store below 25°C. The ideal range is between 5°C and 21°C.
• If the storage temperature exceeds 25°C during this 6-month period, the shelf life for the batteries is reduced. Be sure to
recharge these batteries periodically.
• Storage place should be free from vibration, dust, direct sunlight, moisture and corrosive gases.
5.1.4 Backup Battery
CAUTION
It is mandatory that the HAMILTON-C2 is operated with at least one battery installed.
NOTICE
- The backup battery is intended for short-term use only. It is not intended to be a primary power source.
- Hamilton Medical recommends that the ventilators batteries be fully charged before you ventilate a patient. If the batteries
are not fully charged and the AC power fails, always pay close attention to the level of battery charge.
5.1.5 Battery Life Expectancy / Li-Ion Battery Maintenance
• The lifetime of a battery is defined by the capacity loss. A Li-ion batteries capacity is lowered due to the number of charge
cycles, as well as elapsed time. Given normal storage and use, you can expect the battery to deliver 75% or more of its initial capacity after 300 charge/discharge cycles or within 2.5 years of its manufacture date.
• Hamilton Medical recommends replacing a battery when the capacity is reduced to 80% of its designed capacity.
(HAMILTON-C2: 6500 mAh).
• Cycle numbers (cy.) and full charge capacity (fc.) are provided on PAGE No. 1102 (See the Lithium Ion Battery Maintenance Section 5.1.6) in the Service software (SW ≥ 1.1.X).
• The battery’s manufacture date is stamped on top of the battery connector (IEYYWWVV). The date is encoded as follows:
In the example IE110221, the year is 2011 (11), the week is (02), and the software version is (2.1).
• The HAMILTON-C2 software version > 1.1.x checks the battery capacity and does not accept weak batteries. Batteries
with a capacity loss of more than 25% generate the error message Battery calibration required.

Lithium Ion Battery Maintenance
5.1.6 Lithium Ion Battery Maintenance
5.1.6.1 Maintenance Hints
• When the battery is used in a device, a calibration cycle on the battery charger (PN 369136) is recommended once per
year during preventive maintenance.
• Periodical use of the batteries can extend the battery life time and allows the battery a calibration cycle each time it is
recharged.
• When a ventilator is not in use, connect it to mains power for 1 hour every week. Make sure to disconnect it afterwards.
5.1.6.2 Warranty
• Batteries are consumable parts. Therefore they are excluded from the standard warranty - excepting out-of-box failures!
5.1.6.3 Disposal
• Regulations vary country by country. Dispose of the batteries in accordance with local regulations.
NOTICE
When the battery reaches its end-of-life, the capacity is reduced and the battery becomes unreliable. The use of a ventilator
with such batteries may cause wrong fuel gauge information leading to an unexpected ventilation stop when a power fail
occurs!

5.4 Battery Re-calibration
The battery calibration is done automatically.
If the battery fuel gauge needs re-calibrating, the red LED will flash when you put the battery into the battery charger. This
indicator provides feedback on the accuracy of the fuel gauge and avoids unnecessary battery calibration cycles.
You have the option to calibrate the fuel gauge and charge the battery or to only charge the battery. This option is given
because a recalibration cycle is longer than a charge cycle.
To recalibrate the battery, press the calibrate button on the front of the charger.
The blue calibration LED will flash to indicate that the battery is undergoing the re-calibration cycle. There may be a short
delay before the calibration begins. During calibration the discharge resistors will heat up and the fan will operate to maintain the temperature within acceptable limits.
At the end of the procedure the blue calibration LED will illuminate indicating a fully charged, fully calibrated battery.
NOTICE
No action is necessary if only a recharge is required. The charger will automatically begin to charge the battery.
The most common cause of calibration failure is overheating of the battery during discharge. Keep the charger away from
direct sunlight or heat sources.
CAUTION
During recalibration, the battery connector and base of the charger may become warm.

General Information
5.4.1 General Information
If the battery is in need of fuel gauge re-calibration, the red LED will flash upon insertion of the battery into the battery
charger. This indicator provides feedback to the user on the accuracy of the fuel gauge and avoids unnecessary battery calibration cycles.
The user has the option to calibrate the fuel gauge and charge the battery, or only charge the battery. This option is given
because a re-calibration cycle is longer than a charge cycle.
For re-calibration of the battery, please press the "calibration button" on the front of the charger.
NOTICE
No additional action is required for re-charging the battery. The process starts automatically.
The blue calibration LED will flash to indicate the re-calibration cycle. There may be a short delay before the calibration
begins. During calibration the discharge resistors will heat up and the fan will operate to maintain temperature within acceptable limits.
At the end of this procedure the blue LED will stay constant indicating a fully charged, fully calibrated battery.
CAUTION
The most common cause of calibration failure is overheating of the battery during discharge. Please keep the charger away
from direct sunlight or heat sources.

5.4.2 Re-calibration Time
The re-calibration cycle begins by discharging the residual capacity. Then a calibration charge is delivered to the battery. This
is followed by a calibration discharge. Finally the battery is given a regular charge. A calibration cycle will be faster if the battery is fully discharged to begin with.
Re-calibration time (5-4) is governed by the battery voltage and capacity. Larger batteries, and low voltage batteries will take
longer to re-calibrate. Calibration is initiated each time the re-calibration button is pressed, so it is not recommended to press
the re-calibration button part way through the re-calibration cycle.
Calibration begins each time the re-calibration button is pressed. Do not press the re-calibration button part way through the
re-calibration cycle.
The re-calibration cycle is as follows:
1.
Discharge of any residual capacity.
2.
A calibration charge is delivered to the battery.
3.
Discharge of calibration capacity.
4.
The battery is given a regular charge.

Re-calibration Description
5.4.3 Re-calibration Description
Impedance tracking fuel gauges retain accuracy longer than coulomb-counters and can even self re-calibrate in use as long as
there are periods of inactivity in the cycle so that the impedance measurement can be made more accurately.
If no periods of rest are present in the cycle then the Impedance tracking fuel gauge will accumulate the Max-Error at a rate
of 1% every 20 cycles.
Impedance-Tracking fuel gauge re-calibration is achieved by charging the battery, allowing it to rest, discharging it allowing it
to rest again. This algorithm can only be performed on the external charger/calibrator CH5000 (see the Re-calibration Time
Section 5.4.2).
So re-calibration is used to re-set the fuel gauge to match the actual capacity in the battery. In this way, even as the battery
ages and things change, the accuracy and reliability of the fuel gauge can be retained throughout the life of the battery.

Lithium Ion Battery Handling Precautions
5.5 Lithium Ion Battery Handling Precautions
WARNING
• Before using lithium ion batteries for the first time, carefully study this section, including all Cautions and Warnings.
• Keep this section for future reference.
WARNING
• Do not use the battery for a purpose other than those specified. Otherwise, its performance will be compromised and/or
its service life will be shortened. Depending on the equipment in which the battery is used, excessively high current can
flow through the battery, possibly damaging it and leading to acid leakage, overheating, smoke emission, bursting and/
or ignition.
• Do not use the battery in combination with primary batteries (such as dry-cell batteries) or batteries of different capacities or brands. Otherwise, the battery can be overdischarged during use, or overcharged during recharging, abnormal
chemical reactions may occur, possibly leading to acid leakage, overheating, smoke emission, bursting and/or ignition.
• Do not use or leave the battery near a heat source such as a fire or a heater (+80ºC or higher). If the resin separator
should be damaged due to overheating, internal short-circuiting may occur to the battery, possibly leading to acid leakage, smoke emission, bursting and/or ignition.
• Do not put the battery into a microwave oven or pressurized container. Rapid heating or disrupted sealing can lead to
acid leakage, overheating, smoke emission, bursting and/or ignition.
• Do not discard the battery into fire or heat it. Otherwise, its insulation can melt down, its gas release vent or safety features will be damaged and/or its electrolyte can ignite, possibly leading to acid leakage, overheating, smoke emission,
bursting and/or ignition on it.
• Do not immerse the battery in liquid, or allow it to get wet. Otherwise, the protective features in it can be damaged, it
can be charged with extremely high current and voltage, abnormal chemical reactions may occur in it, possibly leading to
acid leakage, smoke emission, bursting and/or ignition.
• Do not pierce the battery with a nail or other sharp objects, strike it with a hammer, or step on it. Otherwise, the battery
will become damaged and deformed, internal short-circuiting can occur, possibly leading to acid leakage, overheating,
smoke emission, bursting and/or ignition.
• Do not strike or throw the battery. The impact might cause leakage, overheating, smoke emission, bursting and/or ignition. Also, if the protective feature in it becomes damaged, it could become charged with an extremely high current and
voltage, abnormal chemical reactions can occur, which can lead to acid leakage, overheating smoke emission, bursting
and/or ignition.
• Do not disassemble or modify the battery. The battery is equipped with built-in safety/protection features. Should these
features be disabled, the battery can leak acid, overheat, emit smoke, burst and/or ignite.
• If the battery leaks and the electrolyte gets into the eyes, do not rub them. Instead, rinse the eyes with clean running
water and immediately seek medical attention. Otherwise, eye injury may result.
• Do not use an apparently damaged or deformed battery. Otherwise, acid leakage, overheating, smoke emission, bursting
and/or ignition of the battery may occur.
• Consider consolidating these three into: Do not expose the battery to fire, flames, or excessive heat such as is generated
by soldering, welding, radiators and so on. If the battery gives off a bad odor, melts, becomes discolored or deformed,
leaks electrolyte fluid, appears in any way abnormal at any time, remove it from the equipment as the battery can leak
acid (electrolyte fluid), emit smoke, burst and/or ignite.
• Do not reverse the positive (+) and negative (-) terminals. Otherwise, during recharging, the battery will be reversecharged, abnormal chemical reactions then may occur, or excessively high current can flow during discharging, leading
to acid leakage, overheating, smoke emission, bursting and/or ignition.
• The positive (+) and negative (-) terminals are arranged in a particular orientation. Do not force the connection if you
cannot easily connect the battery terminals to the battery charger or other equipment. Confirm that the terminals are
correctly oriented. Reversing the terminals will result in reverse-charging, possibly leading to acid leakage, overheating,
smoke emission, bursting and/or ignition.
• Do not connect the positive (+) and negative (-) terminals with a metal object such as wire. Do not transport or store the
battery together with metal objects such as necklaces, hair pins, etc. Otherwise, short-circuiting will occur, over-current
will flow, causing the battery to leak acid, overheat, emit smoke, burst and/or ignite or the metal object such as wire,
necklace or hair pin can generate heat.
• Do not connect the battery to an electrical outlet, vehicle cigarette lighter, etc. When subjected to large voltage, overcurrent can flow on the battery, possibly leading to acid leakage, overheating, smoke emission, bursting and/or ignition.
• Do not recharge the battery near fire or above 45°C. Otherwise, hot temperatures can trigger its built-in protective features, inhibiting recharging or can damage the built-in protective features, causing it to be charged with an extremely
Hamilton Medical | HAMILTON-C2 Service Manual

Lithium Ion Battery
high current and voltage and, as a result, abnormal chemical reactions can occur in it, possibly leading to acid leakage,
overheating, smoke emission, bursting and/or ignition.
• To recharge the battery, use the battery charger specifically designed for the purpose and observe the recharging conditions, refer to 5.2. A recharging operation under non-conforming recharging conditions (higher temperature and larger
voltage/current than specified, modified battery charger, etc.) can cause the battery to be overcharged, or charged with
extremely high current. An abnormal chemical reaction can occur in the battery, possibly leading to acid leakage, overheating, smoke emission, bursting and/or ignition.
• If recharging operation fails to complete even when a specified recharging time has elapsed, immediately stop further
recharging. Otherwise, acid leakage, overheating, smoke emission, bursting and/or ignition can occur.
CAUTION
• If you find rust, a bad odor, overheating and/or other irregularities when using the battery for the first time, return it to
Hamilton Medical AG.
• If acid leaking from the battery comes into contact with your skin or clothing, immediately wash it away with running
water. Otherwise, skin inflammation can occur.
• The battery incorporates built-in safety devices. Do not use it in a location where static electricity (greater than the manufacturer’s guarantee) may be present. Otherwise, the safety devices can be damaged, possibly leading to acid leakage,
overheating, smoke emission, bursting and/or ignition.
• Do not use or subject the battery to intense sun or above 65°C. Otherwise, acid leakage, overheating and/or smoke
emission can occur. Also, its guaranteed performance will be lost and/or its service life will be shortened.
• The guaranteed recharging temperature range is 0°C to +45ºC. A recharging operation outside this temperature range
can lead to acid leakage and/or overheating of the battery and may cause damage to it.
• Store the battery in a location where children cannot reach it. Also, make sure that no child takes the battery out of the
battery charger or equipment.

Allows aligning the gain and offset for voltage-offset of the Inspiratory Valve.
Sets Offset 1 (low pressure) at 20 mbar blower pressure and Offset 2 (high pressure) at 60 mbar blower pressure when
required Qvent flow is reached.
NOTICE
− Confirm that the Technical State is updated with the current Inspiratory Valve serial number AND revision number, refer
to Modify Tab 8.8.3.
− The HAMILTON-C2 needs a warm-up period. Make sure it was running for at least 20 minutes in the Ventilation Software.
The Inspiratory Valve has a flow-voltage-hysteresis, in that the valve opening characteristic is different from the valve closing
characteristic. The valve needs to be calibrated with either the opening process or the closing process. Based on the design
and pressure control mechanism, the Inspiratory valve is calibrated with the closing characteristic.
The required flow adjustment depends on the Inspiratory Valve revision:
• MSP160230/00 –> 12 l/min (Qvent)
• MSP160230/01 and higher –> 18 l/min (Qvent)
The Technical State needs to contain the correct Inspiratory Valve revision to ensure proper control function
Inspiratory valve calibration:
1. Touch the Insp. Valve Button.
2. Wait approximately 10 seconds until the flow has stabilized.

• Patient Alarms: (Alarm code 100000) Alarms related to : Pressure, Flow, Volume, Apnea
– High Priority Alarms
– Medium Priority Alarms
– Low Priority Alarms
• Technical Alarms: (Alarm code 200000) Alarms related to: Temperature, Battery, Valves, Sensors
– High Priority Alarms
– Medium Priority Alarms
– Low Priority Alarms
Technical Faults Technical Faults end up in one of the following states:
• Fatal -> Safety Mode: (Alarm code 300000)
– In case of some technical failure the ventilator switches to SAFETY Mode. This gives the user time for corrective actions,
such as organizing a replacement ventilator. The turbine runs constant to create Pinsp. The expiratory valve switches
system pressure levels between PEEP and inspiratory pressure. Patient monitoring is nonfunctional during safety ventilation. You must turn off the ventilator power to exit safety ventilation.
• Fatal -> Ambient Mode: (Alarm code 400000)
– If the technical fault alarm is serious enough to possibly compromise safe ventilation, the ventilator enters the ambient
state. The inspiratory channel and expiratory valve are opened, letting the patient breathe room air unassisted. You
must switch off ventilator power to exit the ambient state.
• Invisible Technical Faults (Alarm code 500000) / Technical Note (since < 2.2.0)
– These are classed as “Invisible Technical Faults” and are not shown on the LCD Display during operation. They refer to
exception handling performed by ventilator during operation, and are for Hamilton Medical internal use. Do not consult
Hamilton Medical AG Technical Support concerning these technical faults. They have no significance for hospital workers or Hamilton-Medical Trained Field Service Engineers.

Improvements / Corrections
The following bugs were solved:
Ventilation mode:
• The ambient and the safety mode is not displayed any more as regular TF
xxx’xxx In case of a TF leading to ambient mode "Ventilation cancelled" will be
displayed.
• In case of a TF leading to safety mode "Safety ventilation" will be displayed

• Suctioning tool is now displayed in the options list
• Occurrence of watchdog failures has been reduced again
• Known technical faults during suctioning maneuver do not occur anymore
• GUI "black holes" problem solved
• RTC time will not be lost during ventilation
• Technical event: 243005 (loudspeaker sounds continual) will only be checked
during start-up
• Technical event: 232037 (Unknown alarm) during the CO2 calibration will not
appear anymore
• The sequence of the component test has been improved
• Service software:
– Technical state now displays all hardware revisions in one window
– Pressure calibration procedure is adapted to the new expiratory valve cover
with the metal inlay: With the expiratory valve cover (revision 02) the
pressure inside the breathing circuit can no longer be adjusted to 50 mbar
(51 cmH2O), because the new covers are significantly tighter than the
previous version. Therefore the pressure will be calibrated by comparing
the external reference (pressure gauge) with the internal measurement
displayed on screen (Pvent_control). Furthermore the saving of the gain
value (adjustable with turn knob on screen) will be disabled if the
difference between the Pvent_control and Pvent_monitor resp. Pressure
sensor Paw value is more than 3 mbar.
– Technical fault and event during performing the service software will be
suppressed
– Pneumatics 1 -> Exp. valve test: The test limiting values could be enlarged
– The sequence of the component test has been improved

Improvements / Corrections
The following bugs were solved:
• Watchdog Alarm Routine: With the new software version, the probability of
watchdog failures is significantly decreased
• Battery over temperature: A plausibility check has been introduced to avoid
false positive alarms about hot batteries
• DuoPAP: The alarm limit has been adapted to avoid false positive alarm "Disconnection on patient side"
• "Exhalation port occluded" in NIV: The alarm has been eliminated. Consequently the LiteCircuit has been withdrawn from the product line.
• CO2 curve transmission over RS232: The new unit for CO2 curve transmission
over RS232 is mmHg instead of cmH2O
• Language files: The following language files have been updated: Spanish, Portuguese, Chinese
• Intersurgical LiteCircuit: With the release of the software version 2.0.7 for the
HAMILTON-C2 we will withdraw the Intersurgical LiteCircuits from our product
lines for the HAMILTON-C2, Hamilton-C1 and Raphael. The use of the LiteCircuit bears the potential risk, that the whisper valve gets blocked and CO2 is not
effectively removed. The affected part numbers are:
– PN 151817 LiteCircuit Standard
– PN 151819 LiteCircuit 580

341001 during the suctioning maneuver. Solution: Install SW 2.0.3: Sighs are
suppressed during suctioning.
The following improvements were implemented:
• Labeling: We used the chance and made improvements on the software labels.

has been implemented.
The High Pressure O2 Inlet Filter (PN 160491) is part
of the DISS (PN 160470) or NIST (PN 160471) Connector.
For devices which do not have a High Pressure O2
Inlet Filter installed, we strongly recommend installing
the filter to avoid device malfunction.
DISS Connector with Mounting Adapter
NIST Connector with Mounting Adapter
For this purpose, we provide the following solutions:
1.

Assembly (MSP160226 Revision 00 and
Revision 01), the following items need to
be ordered for the update:
High Pressure O2 Inlet Filter
– Mounting Kit (PN 160496, includes Mounting
Adapter (PN 160494))
– O2 DISS Connector (PN 160470)
or
– O2 NIST Connector (PN 160471)
2.
HAMILTON-C2 with Oxygen Mixer Block
Assembly (MSP160226 Revision 02), the
following items need to be ordered for the
update:
– O2 DISS Connector (PN 160470)
or
– O2 NIST Connector (PN 160471)
The High Pressure O2 Inlet Filter (PN 160491) is part
of the yearly Preventive Maintenance and can be
ordered separately or order the HPO Inlet Filter Service Kit (PN 160497).
NOTICE
A number of devices with Mixer Block Assembly (MSP160226) REV 02 (SN 1590 - 1625) are not equipped with the large O2
connector seat. For these devices, it is necessary to order the Mounting Kit (PN 160496) together with the DISS or NIST connector.

Orifice Tube
Used in the test configuration to perform adjustments in the service software.
Oxygen Sensor
A small, replaceable, plastic unit used by the HAMILTON-C2 to measure oxygen concentration.
The Oxygen Sensor reacts to the presence of oxygen, producing a voltage output in proportion to the oxygen
concentration.
The Oxygen Sensor must be replaced after a period of service, when it can no longer be calibrated. Typically,
about one year.
Oxygen Sensor Calibration
A procedure which supplies a controlled flow of air, oxygen and air/oxygen mixture to the Oxygen Sensor for
calibration.
Pambient
A sensor which measures the ambient pressure or the room pressure.
Patient Alarms
An alarm indicating that there is a problem or potential problem in ventilating the patient.There are three levels of patient alarms: high, medium and low. They are indicated by beeps on the loudspeaker, messages on
the display and the alarm lamp.
Patient Breathing Circuit
A Patient Breathing Circuit carries the air/oxygen mixture to the patient and carries the expired (exhaust) air
from the patient. It may include Tubings, Mask, Inspiratory Filter, Flow Sensor, Nebulizer Jar, Expiratory Valve
Cover and Membrane.
Paw

Preventive Maintenance
(PM)
A term used for periodic maintenance of a device with specific planned tasks and items to check, adjust and
replace.
Principal Gas Flow
The main gas flow through the HAMILTON-C2 from the HEPA Filter for air and the oxygen inlets to the
patient, and then from the patient through the expiratory valve.

Used to measure the air/oxygen flow into the Patient Breathing Circuit.
Rinse Flow
A very small, continuous flow of gas through both the blue (patient side; proximal) and clear (ventilator side;
distal) tubes to the Patient Flow Sensor.
The flow minimizes the possibility of tube blockage, and hinders the potential migration of bacteria and
viruses from the patient’s expired gases through the tubes, towards the pressure sensors inside the ventilator.
Safety Mode
An emergency state that ensures a basic minute ventilation while giving the user time for corrective actions in
case of some technical fault alarms. The default inspiratory pressure is maintained, the expiratory valve opens
as needed to switch system pressure levels between PEEP and inspiratory pressure, and patient sensing is nonfunctional.

Smart Battery Pack
Li-Ion battery, hot swappable which monitors and communicates the battery condition.
SoH
The State of Health (SoH) is a "measurement" that reflects the general condition of a battery and its ability to
deliver the specified performance compared with a fresh battery. It takes into account such factors as charge
acceptance, internal resistance, voltage and self-discharge. It is a measure of the long term capability of the
battery and gives an "indication" not an absolute measurement, of how much of the available "lifetime
energy throughput" of the battery has been consumed, and how much is remaining. Using the automotive
analogy, it can be compared to the "odometer"display function which indicates the number of miles traveled
since the vehicle was new.
T-Fitting

Technical Events
A very minor fault or event recorded by the HAMILTON-C2 in the Event Log for use only by software developers.
Technical Faults
An alarm condition indicating a major malfunction of the HAMILTON-C2. (This contrasts with an alarm, that
indicates a problem with the status of a patient.) Technical Faults are intended to alert users and engineers of
the need for intervention, and are recorded in the Event Log.
Test Configuration (TC)
A particular configuration of devices and tubings use to perform the tests/calibrations in the service software.
Touch Screen
An interaction method where the LCD display screen can be touched with a finger to activate or select a function.
Trolley
A part of the HAMILTON-C2 on which the ventilator is mounted for transport within the customer location.
Update
An update is an improvement to an existing function. An update normally involves only software. A software
update is generally a revision number increment in a digit after the decimal point: for example, from 3.2 to
3.3.
Upgrade
An upgrade is the addition of new functions to a device. There are three ways to perform an upgrade:
• Add a hardware item that offers additional functions
• Upgrade to a higher software revision indicated by a higher value before the decimal point: for example
01.03 to 02.00
• Upgrade to a higher type of software
