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.
