UNISAB S-Control has an alarm relay
which changes position when an alarm situ-
ation occurs in the compressor. This relay
can be used to provide a remote alarm
(flashing light or warning bell). Please refer
to the wiring diagram.
Reverting to factory settings for
alarm limits
If you have coded in new limits, it is pos-
sible to revert to the alarm limits originally
set by SABROE. This is done by using the
configuration function. Please refer to the
chapter
