3.14Alarm Time Delay

Each individual alarm can be programmed with a time delay (Table 13), causing the unit to delay a specified amount of time (0-255 seconds) before recognizing the alarm. The alarm condition must be present for the full amount of the time delay before the alarm will sound. If the alarm condition is diverted prematurely, the alarm will not be recognized and the time delay will automatically reset.

NOTE

For software alarms such as “loss of power” and “short cycle,” the time delay should be left at the factory default of 0.

3.15Common Alarm Enable

Each individual alarm can be selected to activate/deactivate the common alarm relay. If the energize common alarm function is set to YES, the relay is energized immediately as the alarm is enunciated, and de-energized when the alarm condition has cleared. If the alarm is completely DISABLED, the alarm has no effect on the common alarm relay. Use the UP/DOWN arrows to scroll to a particular alarm, press the ENTER button to select it, then press the ENTER key again to select Yes or No.

TOMIZED.

The text for custom alarms can be changed at any time by selecting “CUSTOM ALARMS”. To change the text for a custom alarm, select the alarm you would like to change, 1, 2 or 3. Using the UP/DOWN arrows, step through the list of seven standard alarm messages (listed below) and two custom alarms. Select the alarm message desired and store it by pressing ENTER.
