10.1.7 Termination of alarm
The condition for termination of an alarm can be selected from two basic principles:
‐ Automatic reset of all alarms after correcting the cause
‐ Manual reset of all alarms after correcting the cause
Manual reset can be performed as follows:
‐ By switching off the controller, also while alarm is still active
‐ By local BT 300 x Operator Interface connected to DISPLAY interface
‐ Via CAN bus interface via the system centre / store computer / operator interface in the E*LDS system
‐ By manual shutdown (230 V AC digital input), also while alarm is still active.
10.2 Messages
States outside normal operating conditions but not constituting an alarm state are reported via the interfaces
and entered in the message log.
Examples of messages:
‐ Electric power failure
‐ Change of setpoint
‐ Manual shutdown
‐ Defrosting terminated by safe defrost time
10.3 Transient alarms and messages
Transient alarms are one-time event alarms and are not time stamped for send time. As a result, transient
alarms are not deleted automatically after the event and must be cancelled manually. This applies regardless of
the setting made for
Selfholding (Menu 6-2-3).
The following are transient alarms:
‐ Time-terminated defrosting
‐ Change of setpoint
‐ Electric power failure
‐ First start
10.4 Message log
A maximum of 25 alarms and messages with receive and send date and time are entered in the message log.
The alarms and messages are stored in a ring buffer. When the ring buffer is full, the next new en­
try deletes the oldest entry.
