Bacharach MGS SERIES User manual

1: OPERATING AREA AND CONDITIONS
The Bacharach MGS Series controllers provide local
alarm status indicaons (via mul-colored, per-
channel LEDs) as well as common single-level or
dual-level digital (relay) alarm outputs based on 1, 2,
4, or 6 input signals and 1 or 2 user-definable
set-points.
MGS Controllers support mulple input sensors/
transmiers (1, 2, 4, or 6 channels) based on the
model of the controller. Inputs are standard 4-20 mA
signals from MGS-series sensors or any standard,
linear, 4-20 mA transmier.
The instrument is powered 100V-230V AC (50-60Hz) or
12V DC (specified at me of order).

5: WIRING
1: Strip 0.2 to 0.25 inches (5 to 7 mm)
of wiring insulaon.
2: Connect the wires as indicated.
SHIELD WIRE WARNING: Connect the
shield of the power wires to the earth
ground of the central control system
(e.g., chassis, ground bus bar, etc.).
WARNING: The mains power supply
cable should be of an approved type
based on local regulaons. Connecon
to the mains power supply must be
made via an approved, readily-
accessible, switched and fused plug and
socket (or as per local wiring regula-
ons) which should be within 19 feet (3
meters) of the sesnor/transmier.
CABLE OPENINGS: The metal controller housing
provides a number of PG7 openings for cable glands
or plugs.
NOTE: Aer wiring is completed,
carefully re-assemble the enclosure and
its components.
Refer to the User Manual (part number 6709-
9000) at www.MyBacharach.com for detailed
instrucons on accessing the internal components
for wiring.
Refer to the Controller manual (part
