12. Operation
Status and alarm messages are indicated via indicator lights in
the control panel. See section
8.2 Status indications . If the
outputs of the pump set are connected to a building management
system, the operation can be monitored remotely. To remedy any
faults arising, see section
15. Fault finding .
The three possible modes are described in the following sub-
sections:
• automatic operation (normal operation)
• manual operation (for start-up and after service work)
• test run.
12.1 Automatic operation
Once the pump set has been installed and started up according to
the installation and operating instructions, no further operation is
necessary.
The pump set works automatically and switches itself on as soon
as water is drawn from the sprinkler system and the pressure
switch detects a pressure drop.
