6.4 CXCI Reset
CAUTION
Before removing a CXCI from a live system, or performing controller maintenance, an external
LVD inhibit (or override) is required to avoid a disruption of service. See Section 6.5.
6.4.1 Soft Reset
The reset button, located on the front panel of the optional CXCI, is for restarting the microprocessor. When
pressed momentarily, the unit beeps twice then resets. The front-panel LED’s will illuminate temporarily, but will
extinguish after the system has finished its 15-second self-test.
6.4.2 CXCI IP Address Reset
To reset the IP address, press and hold the front panel reset button for three seconds. The CXCI unit will beep
three times, 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 will allow local access; e.g., with a laptop and a standard network crossover cable. See current version
software manual for details.
6.4.3 CXCI Hard Reset
There is a second reset button located to the right of the front panel on the side of the CXCI. This may be used to
restart the microprocessor in the event that the front panel (soft) reset button fails to operate as described above.
CAUTION: Use of hard reset may cause loss of data.
To access the hard reset button, remove the rectifier module adjacent to the CXCI.
6.4.4 Time Settings
The CXCI, upon startup*, will set the time based on the following:
• Attempt to synchcronize with the NTP server (see www.NTP.org).
• Retrieve the last time stamp from the Event Log.
• Retrieve the last time stamp from the Statistics Log.
• Set the time to 2005-01-01 midnight.
*
Whenever the unit is reset or power is completely removed from the CXCI.
6.5 LVD Control
CAUTION
Before removing a CXCI 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 CXCI to resume automatic control of the LVD contactor, check that the AUTO IN (green) LED is lit
confirming that the CXCI will keep the LVD contactor engaged. Then you may return the LVD Control switch
to the AUTO IN position.
