11.4 Termination of alarm
The conditions for terminating an alarm may be selected from either of two basic methods:
Automatic reset of all alarms after the cause of fault is corrected
Manual reset of all alarms after the cause of fault is corrected
The manual reset of the alarm / alarm state can be performed:
By switching off the controller, regardless of whether the alarm is still active
via a local BT 300 x Operator Interface connected to the display port,
via the CAN bus interface using a system centre / store computer / operator terminal in the E*LDS-System.,
Via the manual shutdown (digital input 230 V AC). This can also be done while the alarm is still active.
11.5 Messages
States constituting abnormal working conditions but not an alarm state are reported via the interfaces and
entered in the fault report list.
Examples of such messages:
Power failure
Setpoint change
Manual shutdown
Termination of defrosting by safe defrost time
Failure of evaporating pressure measurement (detected and signalled by VS 3010 pack controller via CAN
bus)
Reporting of manual adjustment of valve opening degree (in Superuser mode only). If the user switches
to manual definition of valve opening degree, control is interrupted and a warning message (Prio 0) is
entered in the fault report list.
11.5.1 Transient alarms and messages
Transient alarms are alarms for one-time events and are not tagged with a send time stamp. As a result,
transient
alarms are not automatically cancelled after the alarm event and always need to be cancelled manually.
This applies regardless of the setting made for Selfhold (Menu 6-2-3).
The following are transient alarms:
Time termination of defrosting
Setpoint change
Power failure
First start
11.5.2 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 entry
deletes the oldest entry.
