WARNING
!
Electrical shock hazard.
Disconnect VAC and VDC power supplies
before servicing.
Failure to do so could result in electric shock
or death.
IMPORTANT: When working with circuit board
components, Bard recommends the use of
an anti-static wrist strap to prevent static
electricity shorts to electronic controls.
LV1000 Controller
The LV1000 controller is part of the Free Cooling
Unit system by Bard. It is used to control up to four
(4) wall-mount air conditioners from one controller.
The microprocessor control provides an easy-to-read
interface with large LCD graphical display. It provides
control for redundancy for the structure and equal wear
on all units. The LV1000 controller is configured for
first on/next on sequence.
Conduit is recommended for all wiring. Route
communication wiring and power supply wiring in their
own separate conduits.
The LV1000 controller is not weatherproof and is
intended for use in weathertight structure.
Mounting the LV1000 Controller
The dimensions of the LV controller are 16" by 12" by
6".
Because the LV1000 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 connection are provided
in both the base, sides and top of the controller.
Ground case before doing any work or do not connect
power (48VDC) to unit until earth ground is connected.
The LV1000 controller includes a fused power supply
terminal in the terminal block. Before connecting wires
to the terminal block, confirm that the fuse in the fuse
holder is in the proper position (active) as shown in
Figure 18.
