Conguration of alarm relay
The alarm relay will be activated upon an alarm signal from
the following groups:
1 - High temperature alarms
2 - Low temperature alarms
4 - Sensor error
8 - Digital input enabled for alarm
16 - Defrosting alarms
32 - Miscellaneous
64 - Injection alarms
128 - Fuse cut out
The groups that are to activate the alarm relay must be set by
using a numerical value which is the sum of the groups that
must be activated.
(E.g.: a value of 5 will activate all high temperature alarms and
all sensor error.
