System Specifications
Electrical Power:
15-24 VDC regulated
Signal Input:
4/20 mA precision differential input
allows this unit to be mounted remotely and powered
from sensor power (internal resistance drop is
100 ohms).
Maximum Current Draw:
300 mA
(In standard configuration and no upscale indication,
the standby current draw is 100 mA)
Display:
20-segment LED bargraph, with a bottom
segment that flashes to indicate power up delay, and
lights continuously to indicate that the power is on
Trip Setting:
5% increments by use of shorting tab
Alarm Indication:
Red LED
Fault Indication:
White LED (at 1.4 mA or below)
Accuracy:
LED readout provides 5% of full scale
resolution. Trip accuracies at these 5% increments are
within ± 1% of set point.
Time Delays:
Alarm relay is 10 second delay on,
30 second delay for reset after alarm condition clears
Power Up Time Delay:
On application of power the
alarm relay will be held in the normal state for one (1)
minute to allow the sensor to stabilize.
Relay Alarm Output:
Relay is rated at 0.5 amp at
24 VDC or 24 VAC, 0.25 amp at 120 VAC. Relay will
trip on Alarm and Fault conditions.
Note: The relay is normally energized and
monitored by a green LED for ease of
troubleshooting.
Operating Ambient Temperature Range:
0
o
F to
+120

F
Storage Temperature Range:
—40
o
F to +160
o
F
Operating Humidity:
5—95% Relative Humidity, non-
condensing
Enclosure:
NEMA 1, gasketed, 16-gauge steel
Weight:
3 lbs.
Dimensions:
6" high x 4" wide x 3.5" deep
Cable Requirements:
#18/3 shielded cable (Belden
#8770) for runs up to 1,000 feet. High current draw
sensors may require larger cable. Contact Honeywell
Analytics for details.
Note: The Manning GM-JR is for use only
in non-classified areas.
