and all the indicators will be lit for about 3 seconds; otherwise the indicator is faulted.
The function of each indicator:
P1 – Pressure inside the separator. If the indicator is lit, it means the controller has given
alarm.
P2 – Pipeline pressure. If the indicator is lit, it means the controller has given alarm.
T1 – Main unit discharge temperature. If the indicator is lit, it means the controller has given
alarm.
T2 – Dry side discharge temperature. If the indicator is lit, it means the controller has given
alarm.
△P1 – Pressure difference before and after the separator. If the indicator is lit, it means the
filtering element must be replaced.
△P2 – Pressure difference before and after the oil filter. If the indicator is lit, it means the oil
filtering element must be replaced.
MOTOR ------ Motor overload indicator. If the indicator flashes, it means the motor overload
contact has been disconnected.
POWER ------ Power indicator. If the monitor is connected with 110V AC power, this
indicator will be always time.
ON ------ Running indicator. If the light is stable, it indicates the machine is running; if it
flashes, it indicates the machine is under Standby mode and can be started at
any time.
AUTO ------ Auto run indicator. If the light is stable, it indicates the machine is auto
running; if it flashes, it indicates the machine is under Standby mode and can
be started at any time.
AIR FILTER ------ Air filter alarming indicator. If the light is lit, it indicates the air filter
needs maintenance.
5. Setting of Running Parameters
Before the compressor is started, the running parameters must be set first.
(1) Press “PROG” key, and the monitor enters the program control mode. At this time, all
user parameters can be checked but are not editable (press Up Arrow and Down Arrow
keys may change value display but controller will not confirm). Press “Sullair Mark Key”
and then “PRG” key, password verification screen will appear. Modify the value according
to user class password setting principles and all user parameters will appear. User may
modify all user parameters using this method. Press Up Arrow key to increase the
parameter value; press Down Arrow key to decrease the parameter value. The lowest line at
the parameter setting screen indicates the allowable range of the parameter setting.

mode.
key, the manual mode
If the compressor is under manual run mode, when pressing
can be changed into auto mode.
If the compressor is under auto run mode, when pressing
key, the alarming signal
can be cleared and the indicator is extinguished.
Under auto run mode, press
key to stop the compressor. At this time, the monitor
will be under manual stop mode.
(3) Sequencing control mode
The following will describe briefly the sequencing control mode. For details, please refer to
“Sequencing control and communication protocol manual of monitor deluxe microprocessor
controller I”.
※
Disabled – Respond to the inquiry command and can send back the machine status and
parameter message; but doesn’t respond to the start, stop, load and unload command of the main
unit (computer).
※
Remote control – Respond to the inquiry command and can send back the machine
status and parameter message; but doesn’t respond to the start, stop, load and unload command of
the main unit (computer). This mode allows remote input of “start/stop” signal.
※
Master/Slave – Respond to all the commands. Note under this status, if the slave unit
doesn’t receive the command sent from the main unit, it can’t be started or loaded. The slave unit
is controlled from the main unit (computer).
※
Sequence time – Send the status message about once a second. Control the machine
based on the sequence time (start, load or unload).
※ Communication ID – Send the status message about once a second. Control the machine
(start, load or unload) based on the machine number (COM ID#).
※ MODBUS – Adopt MODBUS communication. This method is used when using upper
unit for the control.
7. Main Functions
(1) The system features 2 RS485 ports. 1# RS485 port uses sequencing communication protocol
and 2# RS485 port uses Modbus communication protocol. In sequencing mode, no upper unit
or other devices are needed. Simply connect 1# RS485 port of each controller and set all
controllers into sequencing mode. All machines will work in networked control mode.
(2) The system features dew point and main unit current real-time display and alarming functions.
(3) 4 channels of external switch input are provided to monitor post treatment devices and alarm.
(4) 40 entries of alarm records and 60 entries of rolling history operation records in 2 hours (1
entry in every 2 minutes) are provided for the convenience of maintenance and analysis.
Page 15 of 16
Deluxe Microprocessor Controller I –Operation Manual
(5) Fault and fault clearance records for the three filters (oil/air separator filter element, air filter
and oil filter) and dew point temperature.
(6) Clock in Year/Month/Date/Hour/Minute. It records the time of history event and fault
accurately for the convenience of maintenance and analysis.
(7) 2 channels of analog output ports to output 3 types of analog DC0 ~10V value of T1 and P2
value in real-time and loading pressure for user to collect analog value and connection of
transducer.
* Note: Either T1 or loading pressure set point can be output, but not both.
(8) 4 LCD backlight colors (White, Yellow, Blue and Green) are available for different ambient
conditions.
(9) The system features ambient temperature detecting function. The system alarms when
temperature of control IC exceeds 63℃, and machine will be shutdown automatically if
temperature exceeds 68℃.
(10) The system features main unit current protection function. Together with main unit heat relay,
this function protect main unit from being damaged by high current. If current exceeds the
safety current of main unit for over 135 seconds, controller will give “Main Unit Over
Current” alarm and shutdown the machine.
