4 Installation
4.1 Electrical Installation of Controller
4.1.1 Overview
The LPC-300.1 controller has signal processor controlled power converters with switched inverters for the
drive and the bearing coils of the motor. The signal processor allows precise control of pump speed and
impeller position. Figure 10 shows the interfaces of the standalone controller LPC-300.1 with stand-alone
and minimal PLC functions.

LED is on if supply voltage of signal electronics is present.
“Power Output not active”
Red LED
Red LED is off if the switched output stage of the controller is enabled. If the LED is on, the bearing and
drive coils of the motor carry no current.
Reset button of the controller stage. The button is sunk mounted and can be activated for example with a
small screw driver.
Rotational speed display in 100rpm
Button for speed increasing
Button for speed decreasing
