11. Multimaster function

11.1 Systems with two or more outlet-pressure
sensors
If two or more pumps in the system are configured with an
outlet-pressure sensor (standard option), they can all function as
master pumps. As standard, the pump with the lowest number will
be the master pump. From factory, the master pump is marked
with number 1.
If master pump 1 is switched off or stopped due to an alarm, one
of the other master pumps will automatically take control of the
system.
