Configuration Switch Settings
A four-position DIP switch is used to
select two alarm (filter) delays and
three mutually exclusive alarm
modes. The switches are located
next to the wiring termination
blocks.
Leak Detect Filter Delay(SS1)
SS1 selects the leak detect filter
delay, the interval for which a leak
condition must be continuously
detected before an alarm is
triggered:
OFF = 10 seconds (default)
ON = 2 minutes
This feature is useful for eliminat-
ing nuisance alarms. SS1 works
independently of the settings of SS2
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-latching alarms, 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.
