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).
