. If the
system has been commissioned/started up before, restoring the factory settings will
cause all parameter settings made so far to be deleted if they have not been backed
up using the service software.
In multiple pump configurations, the PumpDrives must be reset to the factory
settings using the active master control panel.
7.4 Digital and analog inputs/Digital and analog outputs
In multiple pump configurations, the digital inputs, relay outputs, and analog
outputs must be parameterised individually for each PumpDrive.
7.4.1
Digital inputs
PumpDrive is equipped with six digital inputs (24 V process level). Inputs 1 and 6 are
assigned a fixed function:
▪
Digital input 1: Start/stop command for single-pump operation, enable in
multiple pump configurations
▪
Digital input 2: Start/stop command in multiple pump configurations (must be set
manually)
Digital input 6: Changeover to multiple pump configuration
The functions of inputs 2 to 5 are user-defined:
