Listed By
UL 916 (PAZX), cUL C22.2
No.205 - M1983 (PAZX7), FCC Part 15 -
Subpart B - Class A.
Mounting
Screw the LGC into an enclosed panel using
the mounting holes provided on the cover
plate. Be sure to leave about 2 inches (5
centimeters) on each side for wiring.
CAUTION
Changes or modifications to this
unit not expressly approved by the party
responsible for compliance could void the
user’s authority to operate equipment.
Wiring
The LGC connects to the CMnet through a
CMnet Connection port. The LGC also
provides an EIA-232 port for diagnostic
purposes. You can connect an optional
BACview
1
or BACview
2
keypad display unit to
the auxiliary device port.
You must use SuperVision to transfer memory
to the LGC. You can connect a portable
computer running SuperVision to the LGC
using the module’s Access port. For more
information about connecting to a
workstation, refer to “Formatting the Module”
on page 6.
Power
CAUTION
The LGC module is a Class 2
device (less than 30VAC, 100VA maximum).
Take appropriate isolation measures when
mounting the LGC module in a control panel
where non-class 2 devices or wiring are
present.
You can power several modules from the
same transformer if you maintain the same
polarity.
The LGC has an operating range of 21.6VAC
to 26.4VAC. If voltage measured at the
module’s power input terminals is outside this
range, the module may not work properly.
Since the module’s address is factory-set as
#1, you do not need to set the address.
1. Turn the module’s power off. This
prevents the module from being powered
up before the proper voltage is verified.
2. Make sure the 24VAC power source is off.
3. Connect the power wires to the module’s
power terminals labeled Ground and
24VAC (see Figure 1 on page 2 for
location).
4. Apply power to the transformer.
5. Make sure that 24VAC is present at the
module’s power input terminals.
When the module turns on, the Run and
Error LEDs turn on and the Run LED
begins blinking. See
