LC5000-100 CONTROLLER
The Bard-Link
TM
LC5000-100 controller is part of
the wall mount Free Cooling Unit system. It is used
to control up to 12 wall-mount air conditioners from
one controller. The microprocessor control provides an
easy-to-read interface with large LCD graphical display.
It provides total redundancy for the structure and
equal wear on both units. The Bard-Link
TM
controller is
configured for lead/lag/lead/lag sequence.
Conduit is recommended for all wiring. Use separate
conduits for communication and supply wiring.
1. Mounting the Controller
Because the Bard-Link
TM
controller utilizes a remote
temperature sensor as opposed to one located in the
controller box, the controller itself can be installed in
any indoor location that is suitable, preferably at eye
level. Four (4) mounting holes are provided for mounting
to the wall and holes for conduit connections are provided
in both the base, sides and top of the controller.
Electrical shock hazard.
Disconnect VAC power supplies before
servicing.
Failure to do so could result in electric shock
or death.

WARNING
Single Unit Operation
Bard thermostat 8403-077 or 8403-078 can be used in place
of the BARD-LINK
TM
PLC controller when only one W-Series wall
mount air conditioner is being installed. If using a thermostat
instead of the PLC controller, the alarm logging and remote
communication capabilities of the controller will not be available.
8403-077 Single Unit Controller, backup real time clock, buzzer
and backlit display.
8403-078 Single Unit Controller, buzzer and backlit display.
For optimum temperature sensor performance, the thermostat
should be mounted on an interior wall and away from any heat
sources, sunlight, windows, air vents, air circulation obstructions
and/or any other cause of erratic or false temperature sensing.
Follow the instructions included with 8403-077 or 8403-078 for
wiring connections from the thermostat to the wall-mount unit.
