1 System Description  
The Manning GM-1 is designed to accept a single  
4/20 mA current input signal, plus provide a regulated  
24 VDC supply to operate all sensors manufactured by  
Honeywell Analytics.  
The Manning GM-1 is housed in a rugged 14 gauge  
gasketed steel enclosure. Behind the clear plexiglass  
window is a 20-segment vertical LED bargraph display  
which gives a visual indication of the gas  
concentration.  
The unit has warning and alarm level indications on the  
front panel, and warning and alarm relays allowing the  
user to incorporate functions such as ventilation  
control, remote horns, security system monitoring, and  
automatic shutdown.  
Designed to be highly reliable when properly installed,  
all relays are energized during normal operation, and a  
sensor fault monitoring circuit will indicate a fault and  
trip a dedicated fault relay if the signal falls below  
1.4 mA.  
The unit has an audible horn which will sound if an  
alarm or fault condition is detected. The silence switch  
will silence the horn until the next event. If an alarm  
condition initiates the horn, the horn will clear  
automatically when the alarm relay clears.  
The unit has a power-up delay feature that places all  
outputs in normal conditions for one minute to allow for  
sensor stabilization.  
The Manning GM-1 will support all of Manning  
sensors, including oxygen, which requires a down-  
scale alarm.  
All components that are in contact with voltages above  
40 volts are UL listed, including the enclosure.  
Note: The Manning GM-1 is for use in  
non-classified areas only.

B Wiring  
Relay Wiring:  
All three relays have Form C, dry contacts. Any  
required power source must be within the 3 amp  
rating and fused or current limited to keep from  
damaging the contacts.  
Electrical wiring must comply with all applicable  
codes. Plant equipment that may be involved and  
operating conditions should be discussed with local  
operating personnel to determine if any special  
needs should be taken into account.  
Relay wiring must be run in separate conduit  
from the sensor cable if the relay circuit is AC.  
Nearly all start-up problems are due to improper  
wiring or monitor configuration. Please follow these  
guidelines carefully. Figure 2 presents a wiring  
diagram for the Manning GM-1.  
Sensor Wiring:  
See sensor manual for proper sensor cable.  
See sensor manual for proper sensor location.  
AC Power Wiring:  
Never run AC circuits in the same conduit as  
the sensor cable.  
Use only stranded cable for AC power,  
relay outputs, and sensor input cables.  
Note: Relays are energized in a non-alarmed  
condition so that a power loss in the Manning GM-  
1 will result in an alarm.  
The units must have a proper third wire  
ground for safety and sensor shielding.  
Be sure to follow local codes.  
All AC cables must be kept away from the  
incoming sensor cables, i.e., do not put AC  
cables inside conduit containing sensor  
cables.  
Keep all wiring away from variable speed  
drives and SCR control units to minimize  
electrical noise exposure.  
Electrical Power: 120 VAC, 50/60 Hz, 0.35  
amps.  
Electrical power ground: The unit must be  
properly grounded.  
Risk of electric shock.

3 Operation  
A Display Panel  
C DIP Switch Setting  
A 20-segment Bargraph Display indicates the gas  
concentration level. The bottom LED is always lit to  
indicate power to the display.  
The two position DIP switch in the center of the bottom  
board controls the latching of the alarm light and alarm  
relay. Switch 1 (left) controls the alarm relay. Switch 2  
(right) controls the alarm light. Putting the switch in the  
on (up) position will latch the corresponding function.  
Putting the switch in the off (down) position will cause  
the corresponding function to be not latched (see  
Figure 3).  
The Warning LED indicates the warning level as  
determined by the warning setpoint has been  
exceeded. The Warning LED and Warning Relay  
operate together and never latch.  
The Alarm LED indicates the alarm level as  
determined by the alarm setpoint has been  
exceeded. The Alarm LED and Alarm Relay are  
independently latchable or non-latchable as  
determined by the DIP switch on the main board.  
Standard factory settings are to latch the LED and  
not latch the relay.  
This allows the alarm condition to remain activated if  
desired even if the gas concentration goes back to  
below the setpoint.  
Figure 3: Warning adjustment and DIP switch settings  
The Power LED indicates power to the monitoring  
unit. This LED will flash during the one minute  
power up delay indicating that all relays are held in  
the normal condition to allow for sensor stabilization  
during power up.  
The Fault LED indicates a signal input of less than  
1.4 mA (0.14 volts) at TP Sig. The Fault LED and  
Fault Relay always latch.

D Signal and Setpoints  
F Troubleshooting  
The voltage between TP Gnd and TP Sig indicates  
the current signal received from the sensor. The  
normal range is 0.4 volts to 2.0 volts, which  
The Fault Light and Fault Relay always latch when a  
fault condition is detected. After the condition is  
corrected the Reset switch must be pressed to clear  
the Fault Light and Fault relay.  
corresponds with 4/20 mA. This manual will use the  
voltage at TP Sig to describe the input signal. When  
this signal exceeds the voltage at TP Warning or TP  
Alarm, the warning or alarm function will take place.  
The warning setpoint is user adjustable by looking at  
the voltage on TP Warning and adjusting the warning  
adjust pot until the desired setpoint is reached (see  
Figure 3). The alarm adjust pot and TP Alarm function  
the same way.  
The unit will indicate a fault if the signal is less than  
0.14 volts at TP Sig.  
Some Manning sensors are configured to send a  
signal of 0.05 volts at TP Sig if a sensor fault exists. If  
TP Sig = 0.05 volts, this indicates a properly wired  
sensor is in a fault condition. Proceed to investigate  
the sensor.  
If TP Sig = 0.00 volts, this indicates no signal from the  
sensor. Check for correct wiring or loose connections  
between the sensor and monitoring unit.  
The warning and alarm setpoints are factory adjusted  
as indicated on the data sheet included with your  
GM-1. Never adjust these setpoints outside the range  
of 0.4 to 2.0 volts. Contact Honeywell Analytics if you  
have any questions or want help in determining  
setpoints for your particular sensor and application.  
Each relay has a green LED in series with its coil. If  
this LED is on, this indicates that the relay is  
energized and contacts will be in the normal position.  
If this LED is off, the contacts will be in the tripped  
condition.  
After setpoint adjustment always expose sensor to  
the gas being monitored and verify that the warning  
and alarm lights trigger at the desired concentration  
as displayed by the bargraph.  
Power supply voltages should be checked at  
TP +20V on the display board and at +24 on  
the sensor input terminal block (see Figure 4).  
Both points should be DC Volts as labeled.  
E Start-Up Procedures  
Before applying power, make a final check of all  
wiring for continuity, shorts, grounds, etc. It is usually  
best to disconnect external alarms and other  
equipment from the unit until the initial start-up  
procedures are completed.  
The total sensor current draw can be checked by  
looking at the voltage between the two TP Current  
Draw test points. 1.0mV corresponds to 10 mA, and  
50.0mV corresponds to 500mA, etc. Compare this  
reading with the current draw expected for the  
sensor you are using (see appropriate sensor  
manual).  
After power-up, allow 24 hours for the system to  
stabilize before testing the sensor. Because sensors  
are normally located at a distance from the  
monitoring unit, the test time required and accuracy  
of the response checks will be improved if two  
people perform the start-up procedures and use  
radio contact.  
If questions arise, call Honeywell Analytics.  
Start-Up Test: One person exposes the sensor to a  
small amount of the gas that is being monitored. The  
second person stays at the monitoring unit to  
determine that the sensor, when exposed to the  
target gas, is connected to the proper input,  
responds, and causes appropriate alarm functions.
