Configuration 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
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 and 0 will cancel the relay
function).
