4.1.3
Suppressing false alarms caused by maintenance work (service mode)
During maintenance work on the refrigeration plant, various alarms and messages are generated and do not
need to be forwarded to the service center. This is accommodated by operating the CI 3000 Store Computer in
service mode, during which all remote alarms are suppressed for a defined period of time.
In menu 9-3 the service personnel must activate the service mode and select the time period (1..255 min.) after
which this operating mode is to be automatically exited:
S
On the CI 3000 Store Computer, move to Screen 9-3 (see also Section 7 – Menu Structure)
S
Start service mode by simultaneously pressing the MODE and ENTER (
↵
) keys.
S
Enter the duration of service mode (1 to 255 min.) and confirm with ENTER (
↵
).
S
Start and end of service mode is logged in the message log and reported to all AL 300 Operator Terminals
connected to the LDS System.
Service mode can be reset/cancelled by entering a time of 0 min.
If alarms are generated during the active service mode these are normally entered in the alarm and messages
list of the CI 3000, and, if available, the AL 300 operator terminal. But the horn, buzzer and alarm relays remain
deactivated and automatic fault report transmission is not initiated. In addition, no alarm messages are sent to
any user PC within the installation connected by direct coupling; modem, LAN gateway, Combi Gateway or CAN
bus – PC adapter.
Any alarms that have not been reset in the alarm log when the set service mode time expires cause
the audible signalling devices and alarm relays to be actuated and are forwarded by automatic fault
report transmission.
