8.5.2 Controller IP address reset
To reset the IP address, press and hold the front panel reset button for three seconds. The controller unit will
beep three times, the IP address will be reset (to 10.10.10.201), and DHCP will be disabled. The settings will be
saved and the unit will then reset.
This allows local access, for example to a laptop via an Ethernet cable. See the software manual for details.
8.6 LVD control
The LVD control functions are hardwired directly from the assigned relay output to an optional front panel LVD
override control. Place the LVD auto/override switch to the INHIBIT position to keep the LVD contactor engaged.
To allow the controller to resume automatic control of the LVD contactor, check that the LVD status LED is turned
o.
8.6.1 Operation of the LVD auto and bypass switch and status LED
The LVD auto and bypass switch is used to control the operation mode of the LVD contactor. The INHIBIT mode
should only be used by qualified personnel and only as a temporary measure. During normal operation the switch
is in the AUTO position. In this mode of operation, the LVD contactor is supplied by the controller and the LVD
green LED is turns on. In the event of input power loss due to a rectifier failure or loss of AC power, the controller
will disconnect the battery supply if the voltage falls to a preset voltage.
To manually bypass the controller and force the LVD to stay on regardless of the input from the controller or
the battery voltage, move the LVD auto/override switch toggle to the OVERRIDE position. The INHIBIT mode is
indicated by the LVD status LED which changes from green to yellow. In addition, the alarm LED on the controller
also illuminates and the alarm is logged in the event log.

ATTENTION
Before removing a controller from a live system or performing controller maintenance, an
external LVD inhibit or override is required to prevent a service disruption.
ATTENTION
Do not leave the switch in the INHIBIT position. Doing so may result in a complete discharge of
the batteries during a power failure situation.
