2.14 Resolving Alarms
Table 2.3 lists the alarms that are shown in the Web Interface Advance Settings Menu under the Alarms Tab. These are also the
possible alarms that display in the alarm screens on the local display and Web Interface. Table 2.3 also provides guidelines for fixing
the condition that caused the alarm.
NOTE!
These instructions describe the complete functionality of the controller. Some functionality is dependent on
hardware connected to the controller. Some alarms listed may not display in your system or may be named differently. Refer
to the NCU Configuration Drawing (C-drawing) furnished with your system.
Refer also to the NCU Configuration Drawing (C-drawing) furnished with your system for the factory default “Alarm Severity Level”
settings and “Alarm Relay” mapping to the available alarms.
Rectifier Lost Alarm Description: The rectifier lost alarm occurs if the NCU updates the inventory and finds that the number of
rectifiers is different. Two conditions cause the NCU to update its inventory. The first condition is if the NCU reboots. Every time the
NCU starts up it updates the inventory. The second condition is when a rectifier is installed in the system. This causes the NCU to
update its inventory. When a rectifier is installed, the NCU re-inventories which clears any “Rect Comm Fail” alarms. The NCU then
finds the inventory doesn’t match what it used to and a “Rectifier Lost” alarm is activated.
