11.1 Alarm signaling and monitoring
11.1.1 High or low temperature alarm
High or low temperature is alarmed when temperature rises or falls to the alarm setpoint and the set delay has
expired.
The high and low temperature setpoints are entered in C. High and low temperature setpoints can be set
separately for each temperature zone. The time delay applies to both temperature zones together. This alarm is
inactive during defrosting.
11.1.2 Disabling high or low temperature alarm
Temperature alarms can be suppressed by means of Digital Input 2 (Terminals D21/D22) and 3 (Terminals D31/
D32):
• When Digit Input 2 is active, all temperature alarms for sensors Rx.1 to Rx.5 are suppressed.
• When Digit Input 3 is active, all temperature alarms for sensors Rx.6 to Rx.0 are suppressed.
This does not affect other alarms, in particular Sensor Break alarm. Alarm is enabled when the digital inputs are
not connected or not active.
11.1.3 No defrost alarm
Alarm is generated if defrosting does not take place during a definable interval, but not if defrosting is
suppressed due to high temperature or by demand defrosting.
The sensor name is included in the alarm report for better identification of the measurement location.

The delay for the No Defrost alarm is fixed at 24 hours.
