5.8.8 Service Mode
During maintenance or service work on refrigeration pack systems, a series of alarms and messages is tripped
whose forwarding to a control centre or fault service is not required. The controller can be put into the Service
Mode for this purpose. During this time, any remote alarm signalling is suppressed for a specified time.
The submenu for activation of "Service Mode" is called using this button (see chapter Service Mode -
Suppression of the remote alarm signalling).
The time period (1..255 minutes) after which the suppression of the remote alarm signalling should be
automatically revoked can be selected in the submenu.
If alarms are generated during the time of the activated service mode, these are entered normally in the alarm
and messages lists of the controller and operator terminal (if available). However, the horn, buzzer and alarm
relays remain deactivated and no automatic transmission of alarms is triggered. In addition, no alarms are sent
toanyuserPCintheinstallationconnectedbydirectcoupling,GSMmodem,LANgatewayorCANbus–PC
adapter.
The Service Mode can only be activated / deactivated while logged in (store is then unlocked)! The
activation and deactivation of the Service Mode are logged in the message list and also sent to all
available operator terminals in the E*LDS system. The Service Mode can be revoked at any time by
setting the time period to "0" minutes.
If there are still unacknowledged alarms in the alarm list after the time of the Service Mode has
elapsed, the audible warning devices and the alarm relays are activated and the alarms are forwarded
using the automatic transmission of alarms!
