Liquid Controls LCRII Install E3650-E3651 Series - Manual (Page 36)

Wiring Tables
This appendix provides a tabular description of the wiring connections made to each LCR-II terminal block. It should
be referenced in the event wiring is inadvertently mis-routed in the field, or for general troubleshooting in the event of
a problem.
Jumper J10 on LCR-II circuit board must be set for RS-232
communication protocol.
* For a standard RS-232 terminal (other than the Lap Pad), the
red wire is connected to J3-47.
Jumper J10 on LCR circuit board must be set for RS-485
communication protocol.
The drain wire must be connected to Pin 13 of terminal J6 in the
LCR-II. It must not be connected in the cab. Trim the drain wire
from the cable end in the cab.
The LCR-II Power cable kit includes a fuse holder and fuse to
protect the system in the event of a short circuit in the cable.
Liquid Controls recommends that this fuse be used in all
installations not having a fused accessory block to protect the truck
in the event of cable faults.
