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.

When unpacking the unit, inspect all boxes and
contents for shipping damage. If any screws or
other metal parts are missing, these must be found
to ensure that the printed circuit boards will not be
damaged when power is applied.

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.

checking signal voltages monthly and logging them
on the data sheet included with your Manning GM-1.
Additionally, the sensor being monitored should be
exposed to the target gas on a monthly basis while
all alarm functions are verified at the Manning GM-1.
This will test the sensor and any equipment con-
nected to the relays in addition to the Manning GM-1.
