SECTION 4
Latching Alarm– When a SPA
2
is configured with latching alarms, an alarm condition will not
“clear” (the relay will not change state) until the input returns to a non-alarm state AND manual
reset terminals are shorted.
Note: The alarm latching function is effectively disabled if the manual reset terminals remain
shorted.
These manual reset terminals, labeled “MR” are located on the bottom row of the SPA
2
.

switch from “ALARM FSAFE” to “ALARM NONFS”. Make your selection and press SELECT.
Fail Safe (ALARM FSAFE)– Will remain in an alarm condition even if power to the unit is
removed. Its alarm trip relays are energized whenever the process input is in a non-alarm
condition (including any dead band setting). These relays de-energize when the process input
trips the alarm.
Non Fail Safe (ALARM NONFS)– With this type of alarm relays are energized whenever
the process input is in an alarm condition. These relays de-energize when the process input
returns to the reset point (including any dead band).

enable the input failure alarm by using the UP and DOWN buttons; press SELECT.

breakdown of input .

and DOWN buttons; press SELECT. If enabled “LOWER POINT” appears, then use the UP
and DOWN buttons to set your lower point value, press SELECT. “UPPER POINT” appears,
then use the UP and DOWN buttons to set your upper point value, press SELECT. “EXIT
RANGE” appears. Press SELECT. “EXIT ALRM*” appears. If range alarm not enabled “EXIT
ALRM*” appears.
Note: When setting the Range Alarm, the values in Lower Point must be greater than those of the
Sensor Lower Limit, and less than those set in Lower Range. When setting the Upper Point, the
value must be less than the Sensor Upper Limit, and greater than those set in Upper Range.
