Function of the STE-RS reversing control unit
36
Note
If a pump with an integrated pump control unit is connected,
there will usually be no connection for the external control unit.
An extension for connection to an external control unit is
optional.
The STE-RS reversing control unit serves the purpose of
preventing and removing slight blockages of a connected
macerator caused by fiber materials in order to avoid downtimes.
To this end, the STE-RS reversing control unit causes reversing
processes with alternating forward and backward sequences
whose duration and number is adjustable by means of a PLC and
depending on the current consumption of the drive.
If the blockage cannot be removed by means of repeated
reversing within a defined time interval, the macerator is switched
off and the control unit switches to "Fault".
Blockages can also be prevented by regular automatic reversing
(not dependent on current).
The underlying parameters are entered and saved via the
operating terminal.
The control unit also supports manual reversing.
The integrated motor protection protects the motor of the
connected macerator from damage through overload.
The Multichopper control module is programmed in such a way
that the direction of rotation changes automatically every eight
hours during continuous operation in order to prevent one-sided
wear of the cutting elements. The direction of rotation also
changes with each restart.
The control unit is equipped with an emergency stop switch.
The macerator is started and switched off via the control unit. It is
possible to connect an external control unit (optional for some
versions).
