The Manning Systems GM-JR Gas Monitor Readout/Alarm is a readout/alarm unit that can be configured in a variety of ways to solve many gas concentration and alarm needs at a very affordable price. The readout provides a calibrated 20-segment LED bargraph, alarm and fault LEDs, plus a relay output with easy trip point adjustment.

The GM-JR standard configuration is composed of a single, rugged, miniaturized board mounted inside the door of the enclosure, and a separate terminal board for the sensor and/or power cable connections. The 20-segment LED bargraph has a calibrated scale that is specified when ordered. Alarm trip adjustments are made easily at 5% increments by a shorting bar on the back of the display board.

On power up or after momentary power loss, the bottom bargraph segment blinks during a oneminute power-up delay period. During this time the alarm relay is forced into its "no alarm" condition to allow the sensor to stabilize. After this time delay, the bargraph will stop blinking, indicating the readout is armed.

The GM-JR continuously monitors the incoming 4/20 mA signal from the sensor. If the signal drops below 1.4 mA, the fault LED will illuminate and the alarm relay will trip. The alarm relay is always energized in its normal state, providing additional safety.

The GM-JR has an easily adjusted set-point and relay output in either the "standalone" or "feed through" configuration, plus 4/20mA output in the "feed through" design. With its own plug-in power supply, the GM-JR/Manning sensor combination provides an economical answer for local concentration level information and control capability.

The GM-JR offers unique configuration possibilities for clients who have their own computer control system, OEMs who want to incorporate gas sensing in their design and existing Manning Systems customers who want remote indication other than at their main readout.
