Operating modes
The BAUER Plug & Play separation system can be operated in two main operating modes:
1. Automatic operation with pressure control
Automatic operation with clear effluent pump ( see chapter 7.10.3)
Automatic operation without clear effluent pump (see chapter 7.10.4)
2. Manual operation
Manual operation with clear effluent pump (see chapter 7.10.5)
Manual operation without clear effluent pump (see chapter 7.10.6)
The different operating modes are described further below (see chapter 7.10.3 to chapter 7.10.6).
7.10.1 Automatic Operation
The automatic mode is the preferred mode of operation for the BAUER Plug & Play separation sys-
tem. In the automatic mode the system is regulated via a pressure sensor and a frequency converter.
The pressure sensor measures the pressure in the separator inlet. The desired pressure must be
set in advance by using the potentiometer at the front of the control panel. (see chapter 7.9). If the
pressure in the inlet deviates too strongly from the set value, the frequency converter regulates the
pump speed up or down, until the preset target pressure is reached again. Moreover, in the automatic
mode a shut-off for over pressure (chapter 7.9.3) and a wire break monitoring of the pressure sensor
cable are active. If the pressure in the inlet rises or the cable of the pressure sensor is damaged, the
system automatically switches off.
7.10.2 Manual Operation
The manual operation is designed for building up a starter cake (described in chapter 7.8) / for the cleaning
or "empty run" and for the case that the pressure sensor is damaged. In the manual operation the pressure
in the inlet is measured, this, however, has no influence on the pump speed. In the manual operation the
pump speed should be adjusted in a way that there is some raw liquid manure in the overflow. This way it is
made sure that enough liquid raw manure is supplied to the separator. In order to get a suitable rotation speed
for the pump for each application, the frequency for the pump motor must be adjusted by the second poten-
tiometer at the front of the control panel. The adjustment range of the potentiometer is following:
0 = 5Hz
10 = 80Hz
The adjustment of the speed can vary according to the type of manure or the screen width and ranges be-
tween under 50 hertz or more than 50 hertz.
