Alarms and Messages of UA 410 D
127 Firmware V1.40 - Doku 2.1 06. April 2016
10.1.3 No defrost alarm
Alarm is generated if defrosting does not take place during a definable interval, but not if defrosting is sup­
pressed due to high temperature or by demand defrosting.
The delay for the No Defrost alarm should not be set too small so as to avoid false alarms ( No De­
frost parameter in Menu 6-2-3). If the maximum interval between set defrost times (Menu 3-2) is 48
hours, for example, the delay for No Defrost alarm must be set at least 1 hour longer, i.e. 49 hours
10.1.4 Sensor break alarm
Alarm is generated after the set delay expires (Menu 6-2-3) if the controller detects breakage or short circuit on
a sensor.
Sensor break alarm is always generated for sensors vital to control functions. In the case of optional
sensors, alarm is only generated when the sensors have not been removed from monitoring by sen­
sor scan (Menu 6-1).
10.1.5 Hardware fault alarm
Alarm is generated without delay if the controller detects hardware problems. Malfunction of the following com­
ponents is detected:
‐ Temperature measurement
‐ General fault
‐ Loss of setpoint (memory problems)
‐ Time/date
‐ First start
Priority for transmitting the alarm is governed by the controller priority and type of alarm.
10.1.6 Alarm routes
A detected alarm state is transmitted by the controller by the following routes:
‐ at the alarm relay (floating changeover contact 15/16/18)
‐ a local BT 300 x Operator Interface connected to DISPLAY interface
‐ via the CAN bus interface on a system centre / store computer / operator terminal in the E*LDS-System.
