Introduction

This manual has been prepared to help in the use and installation of the Manning GM-JR Gas Monitoring Alarm

System. This manual will convey the operating details of the alarm system, ensure proper installation, and

demonstrate start-up and routine maintenance procedures.

ATTENTION: This manual must be carefully followed by all individuals who have or will have the

responsibility for using or servicing the sensor. Warranties made by Honeywell Analytics with respect to

this equipment will be voided if the equipment is not used and serviced in accordance with the instructions in this

manual. If in doubt about a procedure, please contact Honeywell Analytics before proceeding.

1System Description

The Manning GM-JR is designed to accept a single

4/20 mA current input signal and provide a 20

segment vertical LED bargraph display which gives a

visual indication of the gas concentration.

The unit has one relay which will trip when a field-

adjustable gas concentration setpoint is exceeded,

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,

the relay is energized during normal operation, and a

sensor fault monitoring circuit will indicate a fault and

trip the relay if the signal falls below 1.4 mA.

The unit has a power-up delay feature that places the

output in a normal condition for one minute to allow for

sensor stabilization.

The Manning GM-JR will support all Manning sensors,

including oxygen, which requires a down-scale alarm.

Monitoring Options:

The Manning GM-JR can be mounted in its own NEMA

1 enclosure or in the door of most Manning sensor

enclosures.

In the “Feed-Through Configuration,” the Manning GM-

JR can operate anywhere between the sensor and the

readout unit, including either a Manning readout or a

customer-supplied computer. In this configuration, the

Manning GM-JR is powered by the same cable which

powers the sensor.

If ordered in the “Stand-Alone Configuration,” the

Manning GM-JR requires a regulated 24 VDC power

supply provided by the installer. Honeywell Analytics

can supply a 120 VAC plug-in DC power supply to

power the Manning GM-JR and associated sensor. In

this case, ask for the “Stand-Alone Configuration”

instruction manual.

Attention: The Manning GM-JR is for use in

non-classified areas only.

2Installation

ALocating Manning GM-JR

When unpacking the unit, inspect all boxes and

contents for shipping damage. If any screws or other

metal parts are missing, they must be found to ensure

that the printed circuit boards will not be damaged

when power is applied.

The control unit is designed to be mounted on a solid

(non-vibrating) wall through four holes in the two

mounting flanges. While the physical location must be

determined in part by local conditions, it is important to

consider the following:

• Protect the Manning GM-JR from rain, snow,

water sprays, cleaning crews, and physical

damage.

• Mount the unit on a solid wall (non-vibrating) at

eye level for convenience in taking readings,

servicing, etc.

• The Manning GM-JR is NOT explosion proof.

DO NOT MOUNT in a hazardous atmosphere.

• Operating temperature for the Manning GM-JR

is 0oF to +120oF.

• Pre-punched holes are provided in the bottom

of the enclosure for cable access. DO NOT drill

holes in the top of the cabinet as this will void

the warranty.

• If hole drilling is required, be sure to remove all

metal filings.

• Mounting dimensions for the NEMA 1 enclosure

are shown in Figure 1.

BWiring

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 considered.

Nearly all start-up problems are due to improper wiring

or monitor configuration. Please follow these guide-

lines carefully. Figure 2 presents a wiring diagram for

the Manning GM-JR in the feed-through configuration.

Relay Wiring:

The relay has Form C, dry contacts. Any required

power source must be within the amp rating and fused

or current limited to keep from damaging the contacts.

Relay wiring must be run in separate conduit from the

sensor cable if the relay circuit is AC.

The maximum relay rating is 0.5 amp at 24 VDC or

24 VAC, or 0.25 amp at 120 VAC.

Sensor Wiring:

Respect minimum voltage requirements.

• See sensor manual for proper sensor cable.

• See sensor manual for proper sensor location.

• Never run AC circuits in the same conduit as the

sensor cable.

Note: Relays are energized in a non-alarmed

condition so that a power loss in the Manning

GM-JR will result in an alarm.

Risk of electrical shock.

Operation

ADisplay Panel

A 20-segment Bargraph Display indicates the gas

concentration level. The bottom LED is always lit to

indicate power to the display.

The bottom LED will flash during the one-minute power

up delay, indicating that the relay is held in the normal

condition to allow for sensor stabilization upon power

up.

When flashing, the Alarm LED indicates the alarm level,

as determined by the alarm setpoint, has been

exceeded. An alarm condition will trip the relay after a

10 second time delay.

The Fault LED indicates a signal input of less than

1.4 mA. A fault condition will also trip the relay after a

10 second time delay.

BSignal and Setpoints

The voltage between TP1 and TP2 indicates the current

signal received from the sensor. The normal range is

40 mV to 200 mV, which corresponds with 4 mA to

20 mA (see Figure 3, Note 1).

The setpoint can be adjusted from 10% to 100% full

scale in 5% increments using the shorting tab and

jumper block on the back of the display circuit board as

shown in Figure 3, Note 2. If the shorting tab is not

installed, the unit will go into alarm.

After setpoint adjustment, always expose sensor to

the gas being monitored and verify that the alarm

light triggers at the desired concentration as

displayed by the bargraph.

CStart-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.

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.

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 gas fumes, is

connected to the proper input, responds, and causes

appropriate alarm functions.

DTroubleshooting

Risk of electrical shock.

The unit will indicate a fault if the signal is less than

14 mV between TP1 and TP2 (see Figure 4, Note 1).

A signal greater than 20 mA (200 mV) must be

considered a high gas concentration.

Some Manning sensors are configured to send a

signal of 0.5 mA if a sensor fault exists. If the voltage

between TP1 and TP2 = 5 mV, this indicates a properly

wired sensor is in a fault condition. Proceed to

investigate the sensor.

If the voltage between TP1 and TP2 = 0.0 V, this

indicates no signal current is flowing. Check

monitoring equipment connections and configuration.

Input impedance must be 250 ohms or less.

The relay has a green LED in series with its coil

(see Figure 4, Note 2). 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.

Power supply voltage should be checked at +24 on

the control unit input terminal block (see Figure 4,

Note 3). The voltage should be 15—24 VDC.

The Manning GM-JR and the connected sensor are

powered from the same supply. The supply must be

capable of supplying 300 mA at 24 VDC for the

Manning GM-JR in addition to the sensor current

requirement (see sensor manual).

The setpoint shorting tab must be installed (see

Figure 4, Note 4). If it is removed, the unit will go into

an alarm condition after the 10 second delay.

If questions arise, call Honeywell Analytics.

EMaintenance

The Manning GM-JR is designed for long life and high

reliability. Honeywell Analytics recommends checking

signal voltages monthly and logging them.

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-JR.

This will test the sensor and any equipment connected

to the relays in addition to the Manning GM-JR.

FReplacement Parts

For replacement parts, contact Honeywell Analytics.

Be sure to give serial number and model number of

unit.
