4.1 Electrical Installation of Controller
4.1.1 Overview
The LPC-2000 controllers have signal processor controlled power converters with switched inverters for the
drive and the bearing windings of the motor. The signal processor allows precise control of pump speed and
impeller position. Figure 26 shows the interfaces of the standalone controller LPC-2000.1 with standalone
and minimal PLC functions and Figure 27 the interfaces of the controller LPC-2000.2 with extended PLC
functions and USB interface for communication.

“POWER INPUT”
AC power input
1
Torque spec. for tightening of connector screws on motor side: Min. = 0.5 Nm, Max. = 0.6 Nm
5
“Power on” Green LED
LED is on if supply voltage of signal electronics is present.

9
“UP” Button
Button for speed increasing
10
“DOWN” Button
Button for speed decreasing
11
“Firmware” Label
Firmware version and revision number
