Pump control with autochange
7 I/O-expander with pump and fan control application
The digital inputs and relay outputs of the I/O-expander board has fixed signals according to
figure 6-1 when the pump and fan control application is selected.
Digital inputs are used for interlock inputs and they all or part of them are active if the use of
interlocks is set active with parameter 9.31. Number of auxiliary drives (par, 9.1) defines
how many inputs are active. The controls of auxiliary drives are connected to relay outputs.
If four- or five-pump autochange is in use then the relay outputs of the basic control board
can be used additionally.
