6.4 Controller Reset
CAUTION: 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.
6.4.1 Soft reset
Use the reset button on the front panel of the optional controller is to restart the microprocessor. When pressed
momentarily, the unit beeps twice and then resets. The front-panel LED lights will illuminate temporarily and then
extinguish after the system has finished its 15-second self-test.
6.4.2 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 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; e.g., to a laptop via a standard network crossover cable. See the software manual for
details.
6.4.3 Controller hard reset
There is a second reset button located to the right of the front panel on the side of the controller. This button is
used to restart the microprocessor if the front panel (soft) reset button does not work.
CAUTION: Use of the hard reset button may cause loss of data.
To access the hard reset button, remove the rectifier module adjacent to the controller.
6.4.4 Time setting
Upon startup, the controller will reset the time using the following sequence:
1) Attempt to synchronize with the NTP server (www.NTP.org).
2) Retrieve the last time stamp from the Event Log.
3) Retrieve the last time stamp from the Statistics Log.
4) Set the time to 2005-01-01 midnight.
6.5 LVD control
CAUTION: Before removing a controller from a live system or performing controller maintenance, an
external LVD inhibit or override is required to avoid a disruption of service.
The LVD Control functions are hardwired directly from the assigned relay output to an optional front panel LVD
override control. Place the LVD Control switch to the INHIBIT position to keep the LVD contactor engaged.
CAUTION 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.
To allow the controller to resume automatic control of the LVD contactor, check that the AUTO IN (green) LED
light is illuminated. This confirms that the controller will keep the LVD contactor engaged. The LVD control switch
can then be returned to the AUTO IN position.
