Parallel relay
The function
parallel relay
makes it possible to switch an additional relay in case of an error.
It is possible to select what kind of incident causes the relay to be switched.
Example: The parallel relay R2 is chosen for the primary pump. Whenever the controller sends
a signal to the primary pump, the relay R2 is switched.
This can be useful to switch hydraulic paths on or off using a zone valve, for example.
