Alarm
Configuration
The Alarm Configuration screen (Figure 4-15) allows reviewing and setting alarm-
related thresholds (minimum acceptable performance levels) for the unit. Alarm
conditions may be reported by alarm relay contacts and/or by an audible alarm. If
an error condition exceeds the preset alarm thresholds, the red Status LED on top
of the front panel, the LOC ALM LED, and the alarm relay are activated.
If the Alarm Reset Timer period elapses with no further errors detected, the alarm
relay and both LEDs clear. If the ACO (Alarm Cut Off) switch is activated while
an alarm condition exists, the Status LED and alarm relay clear. The LOC ALM
LED remains lit until the Alarm Reset Timer period elapses.
To modify the default parameters, highlight the desired statistic, type in the new
value (any number from 0 to 900) and press Enter. If this value is later surpassed,
an alarm indication appears. A field set to 0 causes the CSU not to alarm on that
statistic. Refer to the Installation chapter for more information on manually setting
alarm configurations.
