Installation
A
Locating 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 0
o
F to +120
o
F.
•
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.

Wiring
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.
