Manual Reset
A latching alarm requires a manual reset. There are
two connections labeled “MR” on the SPA
2
top termi-
nal block. These terminals work in conjunction with
the latching alarm function.
When a SPA
2
is configured with latching alarms, an
alarm condition will not “clear”, that is, the relay will
not change state, until the input returns to a non-alarm
state
AND
these manual reset terminals are shorted
and then opened.

1. Select the type of Fault Alarm you require in

Input Failure– You are notified upon breakdown of
