and SS3. While the alarm delay is selectable (factory default is OFF=10 seconds), the cable fault delay is preset at approximately 2 seconds.

Latching or Non-Latching Alarms (SS2)

SS2 selects latching or non-latchingalarms, the setting in which an alarm will latch ON until manually reset:

OFF = Non-latching (default) ON = Latching

The factory default is OFF=Non-latching. If the sensor is in latching mode (ON=Latching) and the leak condition clears itself in the interim, a manual reset is required. While the alarm is latched, the sensor goes into a “sleep” mode and power to the leak detection cable is discontinued. De-powering the cable prevents damage to the cable should it be in contact with the conductive liquid for an extended duration. After a manual reset, the sensor resumes its normal opera- tion, continuously checking for leaks. If the leak condition has not yet cleared but the sensor is manually reset, the sensor will re-alarm after the appropriate leak detect filter delay. SS2 in the ON position will disable the operation of SS3.
