TC Sensor Fail
This menu item enables the Supervisor to set an alarm when a sensor enabled for Temp Comp
fails.
6.5.3.8 Miscellaneous Alarms
Figure 41–Miscellaneous Alarms window showing menu items
Real Time Clock Error
This menu item enables the Supervisor to set an alarm when any change to the CXC’s clock
occurs; due to a battery failure or the real time clock itself failing. The alarm will become active
whenever the date is before Jan. 1, 2000 or after Dec. 31, 2030.
Invalid Device Firmware
This menu item enables the Supervisor to set an alarm in the event that the firmware of a
device (e.g. Cordex rectifier) has become corrupt and is no longer functioning.
Ground Fault Detected (High Voltage CXC only)
This menu item enables the Supervisor to set the value at which the ground fault detected alarm
will activate. The default value is +/-5mA.
Improper Controller Shutdown
This menu item enables the Supervisor to set an alarm in the event that the firmware of the
controller has become corrupt and is no longer functioning.
Invalid Battery Voltage
This menu item enables the Supervisor to set an alarm when the charging voltage is invalid;
e.g., in the event that the sense leads have become disconnected. The alarm activates when
the charge volts signal drops below 5V and halts all control of the system that relies on this
signal. If activated (enabled) an entry will be made in the event log.
System Major
This menu item enables the Supervisor to map a relay to the power system major alarm, which
is activated if there are one or more active MAJOR alarms. A pull-down menu with scroll bars
may be used for navigation.
System Minor
This menu item enables the Supervisor to map a relay to the power system minor alarm, which
is activated if there are one or more active MINOR alarms. A pull-down menu with scroll bars
may be used for navigation.
6.5.3.9 ADIO Alarms
This menu item enables the Supervisor to configure the alarms associated with each ADIO
device. Events occurring on one of the inputs can be programmed to the output alarm relays
using the programming feature for the relay contacts similar to other alarms.
User (or Supervisor) may view the device status under the ADIO Alarms Detail menu, see 6.5.4.
6.5.3.10 Custom Alarms (1-20)
This menu item enables the Supervisor to program 20 separate alarm-triggering equations into
the CXC software. The equations may reference any combination (up to 16) of the analog
inputs, digital inputs, virtual inputs, and alarms (such as Fan Fail) utilizing logical and arithmetic
arguments that simulate the functionality of a programmable logic controller (PLC). See also 7.2
Equation Builder Keypads.
