10.1 Alarm indicators

The most important operating and alarm indications are shown
via indicator lights and/or the display of the controller.
See installation and operating instructions for the controller.
If the controller has outputs for connection to a building
management system, you can monitor the pump set remotely.
To remove any faults, see section 13. Fault finding.
The following four operating modes are possible:

10.2 Automatic operation

Once you have installed and commissioned the pump set
according to the instructions, no further operation is necessary.
The pump set works automatically and switches itself on as soon
as water is taken from the sprinkler system and the pressure
switch thus detects a pressure drop.
The pump set will not be shut down in case of
Note
disruptions.
You can stop the pump set manually via the controller.

10.3 Manual operation

You can also start and stop the pump set manually for a
functional test, for restarting or after service work.
Do not leave the pump room during manual
operation. Observe all operating and fault indications
Caution
as the pump set will not stop automatically in case of
fault (e.g. too high cooling water temperature or too
low oil pressure).

10.4 Emergency operation

This function is only available for pump sets with
Note
diesel engine.
If the diesel engine does not start up in automatic operation after
six start attempts, the automatic operation is blocked. You can
start the pump set manually via the controller.

10.5 Weekly test run
