Introduction
Modern high capacity turbine generators use hydrogen gas as a cooling medium. Two
reasons for using hydrogen are 1) hydrogen has the best heat transfer characteristics of any
gas; and 2) the low atomic weight of hydrogen makes it the lightest and, therefore, has the
lowest density of any stable gas (10 percent that of air at a purity of 98 percent), resulting in
the lowest windage losses.
The hydrogen auxiliary system exists to maintain the quality and quantity of cooling gas
required to ventilate the conducting and rotating parts of hydrogen cooled generators. Gland
seals are used to prevent hydrogen leakage through the clearance between the shaft and
the frame.
In order to maintain hydrogen gas purity of approximately 98 percent, some generators use
a seal gland system, where a small quantity of hydrogen gas is continuously scavenged
from two (collector end and turbine end) seal drain enlargements and discharged into the
atmosphere.
The Dual Hydrogen Control Panel (DHCP) contains two independent Generator Gas Analyzers (GGA’s) and circuitry to control the rate of scavenging in order to maintain high gas
purity. Environment One’s microprocessor-controlled Generator Gas Analyzer (GGA), with
its triple-range sensor cell, is capable of measuring 70 to 100 percent H2 in Air, 0 to 100
percent H2 in CO2 and 0 to 100 percent Air in CO2.
Each GGA continuously analyzes the generator cooling gas, displays gas purity in real time
and has a corresponding 4 to 20 mA output. In the event that the gas purity falls to a warning or alarm level, a visual indication is given and alarm contacts are switched.
The GGA’s triple-range sensor cell also monitors purge gases used during generator shutdown and maintenance. Purge gas purity is displayed and a corresponding 4 to 20 mA
output is provided for H2 in CO2 or Air in CO2.

System Description
The Dual Hydrogen Control Panel (DHCP) is designed for use on hydrogen-cooled generators. It is designed to operate in Class 1, Division 1, Group B hazardous areas. The DHCP
analyzes and, in real time, displays the hydrogen gas purity on built-in numeric displays.
Environment One’s GGA can be supplied as an Ex, CE labeled system for Zone 1 environments. Contact Environment One for details.
The major components of the DHCP include:
•
2 completely independent, generator gas analyzers (GGA)
•
2 hydrogen gas flow indicators with metering valves
•
1 total hydrogen gas flow indicator
•
1 fan differential pressure transmitter and gage
•
3 hydrogen gas purifiers
•
3 moisture indicators
•
4 metering valves
•
Numerous isolation valves
•
2 local display panels that indicate gas purity and specific operating conditions
Gas Analyzers (Sensor Cells QT-290A, QT-290B, Controller PCB
HD0039G01, I/O PCB HD0043G01, Display PCB HD0138G03)
Analyzers and their printed circuit boards (PCBs) are interchangeable. Each analyzer is
comprised of a sensing unit, controller PCB, sensor cells and input/output (I/O) PCB. All
PCB’s are housed in the main junction box (Figure 1); local display panels are mounted on
the front of the panel (Figure 1).
Each analyzer independently provides purity monitoring, calibration, mode selection, sensor
unit control, alarm electronics, data logging, system inputs/outputs and sensing unit
linearization. See Figure 8 for display panel features and functions.
Fail-safe operation of the Gas Analyzers is ensured by:
1. On power-up the GGA must execute and pass qualifying self tests. Failure in any test
results in termination of operation and annunciation of the condition causing the failure.
2. Following power-up and/or system reset, the GGA is continuously supervised by an
independent watchdog monitor that serves to reset it should its operation become
erratic.
HA0156P01 Rev. D

(Gas Analyzers cont’d)
3. The GGA is completely self-supervised and continuously checks itself for legal processor
functioning, internal voltages, analog-to-digital conversion accuracy, integrity of cabling
and relay operation. Any faults are immediately annunciated as “trouble” on the display
and accompanied by a change in the corresponding relay state.
See Analyzer Failure for more information.
Control/Display Panel
The Control/Display Panel provides control of all functions of the GGA as well as complete
annunciation of the status of the GGA (Figure 7). Functions are accessed by means of a
four-button membrane-switch keypad and 16-character Liquid Crystal Display (LCD). Generally, pressing the Fn (Function) key causes the LCD to continuously scroll the names of the
GGA’s available functions. A function may then be accessed by pressing the ENTER key
when the function name appears. To signal confirmation, the function name flashes briefly.
The Display Panel provides Light Emitting Diodes (LEDs) to annunciate the Normal (H2 in
air), Purge (H2 in CO2 and air in CO2), and Calibrate (H2, CO2 and N2) GGA states. In addition, they indicate Warning, Alarm and Trouble conditions. A green LED indicates AC Power.
It is important to understand that, should the GGA go into either Warning and/or Alarm,
it will lock into continuous monitoring of the gas stream. No other function can be
accessed unless the Alarm/Warning Reset key is first pressed.
To permit a system level initialization (“cold start”), a momentary push-button, located behind
the Display Panel (Figure 7) in the upper right hand corner, may be pressed. Since all
calibration constants are stored in non-volatile memory, these values will not be lost should
the system be initialized or should it lose, then regain, AC power.
Sensor Cell Assembly
The sensor cell assembly is comprised of a sampling thermistor and a reference thermistor
— both operated at very low power in a self-heated mode — embedded in a temperatureregulated cell block. Gas purity is derived as a function of the thermal conductivity of the gas
mixture to the heat output of the thermistors under known constraints. See Cell Output
Voltages for a detailed description for the sensor cell.
Flow Indicators with Metering Valves (FI-2971, FI-2972)
Two low-flow gas indicators with needle metering valves are used to adjust the hydrogen gas
flow through each sensing unit (Analyzer 1 and Analyzer 2, Figure 1). Both have a direct read
scale with a range of 90 to 900 cc/min, calibrated with hydrogen.
Note: Flow indication changes with different gases. For hydrogen, the flow should be set for
500 cc/min.
Total Gas Flowmeter (FI-2973)
A high flow gas indicator is used to indicate the scavenging flows (Total Flow, Figure 1). The
high flow gas indicator has a direct read scale with a range of 540 to 5,400 cc/min when
calibrated with hydrogen.
Note: Flow indication changes with different gases. Metering valves adjust the flow of the
collector end low flow, collector end high flow, turbine end low flow and turbine end high
flow. See Flow Calibration for flow settings.
HA0156P01 Rev. D

Differential Pressure Gage (PDI-292)
A differential pressure gage measures the generator fan differential pressure (Fan
Differential, Figure 1). The standard differential pressure gage has dual scales with ranges of
0 to 30 inches H 2O and 0 to 76.2 gm/cm2. Some units may be equipped with special gage
scales.
Differential Pressure Transmitter (PDT-292)
A differential pressure transmitter provides an output signal corresponding to the generator
fan differential pressure (Figure 1). This 4 to 20 mA output is externally provided by the
Mark V and corresponds to 0 to 30 inches H2O. Some units may be equipped with a special
range.
Purifiers
Three gas purifiers remove foreign matter from the hydrogen stream (Turbine End Purifier,
Case Purifier, Collector End Purifier; Figure 1). Removal of oil, water and particles above 12
microns is accomplished through the use of molecular sieve materials and special filters.
The filters are available in replaceable cartridges, HA0139P02.
Moisture Indicators (MI-2971, MI-2972, MI-2973)
Three moisture indicators indicate the downstream presence of moisture in the hydrogen
stream (Turbine End Moisture, Collector End Moisture, Case Moisture; Figure 1). The units
are supplied with a dyed silica gel, which gradually changes from blue (at relative humidity
less than 4 percent) to pink (at relative humidity higher than 40 percent). These devices are
replaceable.
Metering Valves (HO-2971, HO-2972, HO-2973, HO-2974)
Four needle metering valves provide adjustment for the scavenging flow rates (Collector
End Low Flow, Turbine End Low Flow, Collector End High Flow, Turbine End High Flow;
Figure 1). See Flow Calibration for flow settings.

Installation
Follow the installation instructions to ensure proper installation of the equipment. The exact
location of the DHCP should be in accordance with the recommendations made by General
Electric or its authorized representative.
Cabinet Mounting
Choose a location that is not subject to extremes of dust, temperature, vibration or shock.
The panel should be accessible for service, with adequate clearance to open the enclosure
and display panel doors (Figure 1). The DHCP has four foundation bolt openings (Figure 1).
The openings allow you to insert four 5/8-inch bolts for securing the panel to the floor. The
bolts are isolated from the panel through the use of compression vibration insulators. Use
fasteners that are compatible with the mounting surface and able to support the weight of
the panel. Lifting bolts at the top of the panel allow for easy connection to overhead cranes.
Lifting
The DHCP should be lifted by the pair of eye bolts provided at the top of the frame.
Electrical Connections
Prior to applying power to the DHCP unit, ensure that the local power source matches the
power rating on the DHCP nameplate.
The DHCP unit is shipped with all isolation and metering valves closed. All gas lines must be
connected to the DHCP and leak-tested before continuing.
Electrical connections are made through four 3/4-inch male conduit unions at the bottom or
top of the panel (Figure 1). System power requirements are 120 or 220 Volts AC (systems
are supplied for specifically 120 V or 220 V). The AC power source should be reliable and
not subject to severe transients. Total load max.: 400 watts.
Electrical connections, located inside of the main junction box, are accessed by removing 32
3/4” hex captive bolts. Two guide studs are provided for assistance in removal/replacement.
CAUTION! Do not scratch sealing surfaces on the main junction box. The main
junction box lid weighs 50 lbs (22.7 kg). Take precautions during removal. Prior to
opening the main junction box, remove power from the DHCP and ensure the system
is free of hydrogen.
Wire routing should be in accordance with Figure 3 or 4. This ensures that noise generated
from the AC power and contacts does not interfere with the signals. Connections are made
to barrier type terminal strips (Figure 3).
11
HA0156P01 Rev. D
Contacts/Signals
The DHCP includes alarm and status relays (Figures 3, 9, 10). They are:
•
Warning Relay Both a normally open and a normally closed contact (single pole, double
throw configuration) is provided and a warning is signaled by an energized relay.
•
Alarm Relay Both a normally open and a normally closed contact (single pole, double
throw configuration) is provided and an alarm is signaled by an energized relay.
•
Trouble Relay Both a normally open and a normally closed contact (single pole, double
throw configuration) is provided and Trouble is signaled by an energized relay.
•
4-20 mA output signals are provided for Analyzer #1, Analyzer #2 and the DP Transmitter (Figure 3).
•
The 4-20 mA signals for Analyzer #1 and Analyzer #2 correspond to 70 to 100 percent in
Normal mode (H2 in air) and 0 to 100 percent in Purge modes (H2 and CO2 & Air in CO2).
•
Analyzer #1 and Analyzer #2’s output signals are internally powered. These signals
are not to be powered by the Mark V, Mark VI.
•
The 4-20 mA signal for the DP Transmitter is powered by the Mark V, Mark VI.
See Figure 3 for locations of signals on terminal block. See Figures 9 and 10 for description
of conditions where relays are activated.
Circuit Protection
Each GGA is individually fused. A half-amp slo-blo fuse, located on the Input/Output PCB,
provides circuit protection.
HA0156P01 Rev. D

System Operation
The DHCP’s main purpose is to analyze and display the hydrogen gas purity of hydrogen
cooled generators. This section describes system operation.
DHCP Initialization
With system power on, press the RESET push-button on the backside of the DISPLAY
PANEL (Figure 7). Reset each of the two gas analyzer units separately.
The GGA will perform several self tests and, if they are successful, the DISPLAY PANEL will
respond with (a) all discrete LEDs lit; (b) all segments and the tenths place decimal point of
the GAS PURITY display lit; and (c) all pixels of the LCD display on. Within several seconds
(a) all discrete LEDs, except the AC POWER and TROUBLE LEDS, will turn off; (b) all
segments, except the tenths place decimal point of the GAS PURITY display will turn off;
and (c) the display will indicate LINKING …, as the DISPLAY PANEL initiates
communication with the rest of the system. Communication should be established within
several seconds and the LCD display will then echo the results of cold-start initialization:
•
GGA ANALYZER READY
•
INITIALIZING …
•
12 BIT ADC …
•
… CALIBRATED Note: If calibration is unsuccessful then the LCD will display 12 BIT
ADC ERROR. After annunciating TROUBLE, the processor will be stopped because, at
this point in the start-up sequence, this condition is a fatal error. Contact Environment
One at (518) 346-6161.
•
8 BIT ADC …
•
… CALIBRATED Note: If calibration is unsuccessful then the LCD will display 8 BIT
ADC ERROR. After annunciating TROUBLE, the processor will be stopped because, at

One at (518) 346-6161.
•
Iout SET TO 4 mA where Iout is the 4-20 mA GGA output. See below.
•
Tcell = XX.X 0C (where XX.X is the instantaneous cell block temperature). For an indeterminate period (normally not exceeding 15 minutes for a cold start), the LCD will
display the real-time temperature of the sensor cell block. When the temperature rises to
55.0 C +/- 0.5 C, the system will advance and the display will indicate:
•
ANALYZER READY After this last message, all discrete LEDs will go out except AC
POWER and TROUBLE. In response to the prompts NORMAL (H2/AIR), CONFIGURE
VALVES, permit the sample gas to flow through the sensor then press the ENTER key.
This is the NORMAL mode of operation. See Normal for more information.
For a first time installation, it is essential that a gas sensor calibration be performed on the
system. Also, the faults log should be cleared. See System for more information.

Press the Fn key on the GGA. Wait until the display scrolls to the prompt GAS
CALIBRATION then press the ENTER key. The display will scroll the prompts CALIBRATE
H2, CALIBRATE CO2 and CALIBRATE N2. Wait until the display scrolls to the prompt
CALIBRATE H2 then press the ENTER key. In response to the prompts CALIBRATE H2,
CONFIGURE VALVES, permit the hydrogen calibration gas to flow through the sensor. With
the calibration gas flowing the LCD will display the voltage output of the reference cell
sensor in the format Vref=X.XXX VDC. Press the Fn key to cancel the calibration at this
point, if desired; this will permit a return to the main menu. If desired to continue the
calibration, observe the reference voltage and, if it appears stable (i.e., a final change of not
greater than 1 to 2 mV per minute), press the ENTER key.
The LCD will display the voltage output of the sample cell sensor in the format
“Vcell=X.XXXVDC.” Again, the calibration may be terminated by pressing Fn. If it is

continued, observe the sample cell voltage as it adjusts to the flowing H 2 calibration span
gas. When it appears stable (i.e., a final change of not greater than 1 mV per minute, which
occurs within approximately 15 minutes) press the ENTER key. The LCD will display H2
CALIBRATED. This concludes H 2 calibration.
The display will scroll the prompts CALIBRATE H 2, CALIBRATE CO2 and CALIBRATE N 2.
Press the Fn key on the GGA to return to the main menu or to continue gas calibration, wait
until the display scrolls to the prompt CALIBRATE CO2 and press the ENTER key. In
response to the prompts CALIBRATE CO2, CONFIGURE VALVES, permit the CO2
calibration gas to flow through the sensor. With the calibration gas flowing the LCD will
display the voltage output of the reference cell sensor in the format Vref=X.XXX VDC. If
desired to cancel the calibration at this point, press the Fn key; this will permit a return to the
main menu. If desired to continue the calibration, observe the reference voltage and, if it
appears stable (i.e., a final change of not greater than 1 to 2 mV per minute), press the
ENTER key.
The LCD will display the voltage output of the sample cell sensor in the format Vcell=X.XXX
VDC. Again, the calibration may be terminated by pressing Fn. If it is continued, observe the
sample voltage as it adjusts to the flowing CO2 calibration zero gas. When it appears stable
(i.e., a final change of not greater than 1 to 2 mV per minute, which occurs within
approximately 15 minutes), press the ENTER key. The LCD will display CO2 CALIBRATED.
This concludes CO2 calibration.
The display will scroll the prompts CALIBRATE H2, CALIBRATE CO2 and CALIBRATE N2.
Press the Fn key on the GGA to return to the main menu, or to continue gas calibration, wait
until the display scrolls to the prompt CALIBRATE N2, press the ENTER key. In response to
the prompts CALIBRATE N2, CONFIGURE VALVES, permit the nitrogen calibration gas to
flow through the sensor. With the calibration gas flowing the LCD will display the voltage
output of the reference cell sensor in the format Vref=X.XXX VDC. If desired to cancel the
calibration at this point, press the Fn key; this will permit a return to the main menu. If
desired to continue the calibration, observe the reference voltage and, if it appears stable
(i.e., a final change of not greater than 1 to 2 mV per minute) press the ENTER key.
The LCD will display the voltage output of the sample cell sensor in the format Vcell=X.XXX
VDC. Again, the calibration may be terminated by pressing Fn. If it is continued, observe the
sample voltage as it adjusts to the flowing N 2 calibration zero/span gas. When it appears

must remain below the WARNING or ALARM level for a minimum of one minute to generate
an alarm. Should the GGA go into WARNING, it will energize the WARNING RELAY (Figure 3)
and illuminate the WARNING LED. Further system operation is locked out until the WARNING
RESET key is pressed (at which point the GGA will revert to NORMAL operation).
Purge Operation
To monitor a purge operation, first press the Fn key to access the main menu, and then
press ENTER when the display scrolls to the prompt PURGE (H2 in CO2) or PURGE (Air in
CO2) key. In response to either the prompt PURGE (H2 in CO2) or PURGE (Air in CO2),
CONFIGURE VALVES, permit the sample gas to flow through the sensor then press the
ENTER key. The Display Panel will respond with the corresponding PURGE (H2 in CO2) or
PURGE (Air in CO2) LED illuminated. In this mode the 4 to 20 mA current output of each
GGA corresponds to 0 to 100 percent gas purity. There is no alarm level for either of the
PURGE operations.
Mode Menu

The GGA is a self-supervised system and can identify and trap detected faults in its operation. Whenever a fault is detected the TROUBLE LED is illuminated, the TROUBLE RELAY
is de-energized, and a description of the fault is logged (stored and latched). Faults can be
displayed by pressing the ENTER key when the sub-item SHOW FAULTS LOG is displayed.
Fault conditions that can be detected include errors in the system’s 8- and 12-bit analog-todigital converters, power supply voltages, supervisory loop errors and gas sensor cell block
temperature. Press the Fn key to terminate.
The faults log can be erased by pressing the ENTER key when the sub-item CLEAR
FAULTS LOG is displayed. If selected, the LCD will prompt CLEAR LOG? Press the ENTER
key to clear all logged faults. Once executed the display will indicate LOG CLEARED for
approximately two seconds and then go blank, leaving the system in the NORMAL mode.
Pressing the Fn key instead will blank the display and place the system in the NORMAL
mode without clearing the faults.
Pressing the ENTER key when the sub-item RUN DIAGNOSTICS is displayed permits a
readout of the GGA’s initial cell reference voltage, the output voltages of all power supplies,
tests the system’s Normal, Trouble, Alarm and Warning relays, and the Membrane Keypad
on the Display Panel. At any point press Fn to terminate testing. The test sequence is:
1. The LCD will display Vref=X.XXXVDC. This parameter is the voltage of the cell
reference thermistor and was stored at the time of the last calibration of the cell (whether
H2, CO2 or N2).
2. The LCD will display Vh2=X.XXXVDC. This parameter is the voltage of the hydrogen
calibration constant and was stored at the time of the last calibration of the cell.
3. The LCD will display Vco2=X.XXXVDC. This parameter is the voltage of the carbon
dioxide calibration constant and was stored at the time of the last calibration of the cell.
4. The LCD will display Vn2=X.XXXVDC. This parameter is the voltage of the nitrogen
calibration constant and was stored at the time of the last calibration of the cell.
5. The LCD will display Vadc> X.XXVDC. This parameter is the reference voltage of the 12
bit analog-to-digital converter and will range between 3.97 and 4.22 VDC.
6. The LCD will display +5V> X.XXVDC. This parameter is the output of the +5 volt digital
supply and will range between 4.50 and 5.50 VDC.
7. The LCD will display +12V> XX.XVDC. This parameter is the output of the +12 volt
digital supply and will range between 10.8 and 13.2 VDC.
8. The LCD will display +15V> XX.XVDC. This parameter is the output of the +15 volt
analog supply and will range between 13.5 and 16.5 VDC.
9. The LCD will display ”-15V> XX.XVDC. This parameter is the output of the -15 volt
analog supply and will range between -13.5 and -16.5 VDC.

For the above voltages, the LCD will flash an ERROR message alternately with the
voltage if the measured voltage is out of limit.
10. The LCD will display “RELAY TEST …” The system will cause each relay to be
energized. If no errors are detected, the LCD will display” RELAYS PASS.” If an error is
detected, the LCD will display “RELAYS FAIL,” “FAILURE IN,” then “NORMAL RELAY,”
“TROUBLE RELAY,” “ALARM RELAY” or “WARNING RELAY.”
11. The LCD will display “KEYPAD TEST …” Press each key on the Membrane Keypad on
the DISPLAY PANEL, reserving the ENTER key for last (this key will terminate the test).
As each key is pressed the LCD will echo the name of the key.
Program instructions for the microcontroller within the GGA system are stored in Read Only
Memory (ROM) chips located within the system. The program identification and revision
level, in the format P_GGA Rev X.X, can be displayed by pressing the ENTER key when the
sub-item SHOW PROGRAM ID is displayed. Pressing the Fn key terminates this item.
REMINDER! Should the system go into trouble, access the menu items SHOW
FAULTS LOG and RUN DIAGNOSTICS for more information.
Cell Output Voltages
The sensor cell is principally comprised of a sampling thermistor and a reference thermistor
embedded in a temperature regulated cell block. The voltage derived from the reference
thermistor (this voltage is displayed as “cr”) is used to compensate for any non-purity related
variations in the voltage output of the sample thermistor (this voltage is displayed as “s”).
When a cell is calibrated, the value of cr is stored in non-volatile memory as the parameter
Vref. Subsequently, during normal operation, the real time value of cr is mathematically
combined with Vref to form a term compensating s. This operation ensures long-term measurement accuracy of the sensor cell.
The output voltages of these thermistors can be viewed directly (i.e., prior to any computation) in real time by pressing the UP arrow. This information is updated every half second
and is displayed in the format s=X.XXX cr=X.XXX, where, again, s stands for the sample
thermistor voltage and cr stands for the current value of the reference thermistor voltage.
The display of these voltages may be canceled at any time by pressing the DOWN arrow.
The parameter Vref is displayed during calibration and diagnostics.

Maintenance
The Dual Hydrogen Control Panel (DHCP) is designed for reliable, trouble-free operation.
Periodic checks and maintenance are easy. Following the required maintenance checks will
ensure safe trouble free operation of this equipment.
Daily
Check and adjust DHCP analyzer and scavenging flow rates. See Flow Calibration. Check
hydrogen purity.
Weekly
1. Visually inspect the moisture indicators. A blue medium indicates dry hydrogen, while a
pink medium indicates excessive moisture in the hydrogen gas sample that may affect
the stability of the Generator Gas Analyzers. Replace or regenerate the Moisture
Indicator and replace the Gas Purifier if the medium is pink. Refer to Removal of
Moisture Indicators and Gas Purifiers.
2. Blow down purifiers by first removing cap at the base of the isolation valve and then
open the valve itself. It is advisable to have a container available to collect any fluid
contained within the purifier. CAUTION: THE PURIFIERS MAY CONTAIN HYDROGEN
GAS; USE PROPER SAFETY PRECAUTIONS.
Every Six Months
1. Check Analyzer power and calibration voltages.
2. Calibrate Generator Gas Analyzers, as necessary.
3. Run Diagnostics.
When the Generator is Down
During periods when the generator is shut down, it is recommended that either a) power be
maintained to the DHCP, or b) the DHCP be isolated by placing all isolation valves in “off”
position.
