6.9.4 LVD Control (Load Disconnect or Battery Disconnect)
The disconnect option is controlled by and connected internally to relay K1.
LVD Inhibit
Should it be necessary to remove a CXCM1 series controller, the customer connection board (on the
front of the shelf) provides shorting pins (JP2) to inhibit (or override) the LVD Control function. See the
customer connections drawings.
If the LVD is controlled on NC contacts (factory default for LVD option), then JP2 pins 1 and 2 must be
shorted together to maintain LVD operation. If the LVD is controlled on NO contacts, then pins 2 and 3
must be shorted together. For normal operation, the factory-supplied shorting jumper should be left on
pins 3 and 4.
6.9.5 LVD Control Alternative
The LVD Control functions can be hardwired directly from an alarm output relay to an external LVD
contactor (or panel). See Controls Menu Defaults in the controller software manual.
