6.1 Variable-Frequency Drive Overview
LED
Description
PWR
Lights when the machine is connected to the power supply.
RUN
Lights during operation of the machine.
FLT
Lights when a fault occurs.
Blinks if maintenance is necessary (every 8000 operating hours).
Maintenance counter can be reset via terminal 14 (Digital In 4) of the
control unit.
Fault codes: see chapter 9.1 ‘Fault Tracing’ in the document ‘Pump
Control Instructions’ part no. 0870166596
RDY
Lights when the machine is ready for operation and no faults occur.
Blinks in case of a warning.
6.2 Pressure Control
Pressure control of the machine requires a pressure transmitter. A suitable Busch
pressure transmitter is available as accessory.
In case of dusty application a filter must be installed upstream the pressure transmitter
to avoid malfunction or damage to the pressure transmitter.
Depends on the pressure transmitter the DIP switch SW3 must be switched either to
current mode (4 ... 20 mA) or to voltage mode (2 ... 10 V) (see
).
During pressure control the machine controls the speed according to deviation
between the actual value and the desired pressure value.
In case of the actual value is above the desired pressure value the speed of the ma-
chine increases. Drops the actual value below the desired pressure value the speed of
the machine decreases.
In case of a long operation with the minimum speed the machine switches to the sleep
mode, that means the machine stops and starts automatically when the actual value
exceeds the desired pressure value by 50 mbar.
