Installation
4.1 Electrical Installation of Controller
4.1.1 Overview
The
LPC-200
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.
shows the interfaces of the standalone controller
LPC-200.1
with stand-alone
and minimal PLC functions and
the interfaces of the
LPC-200.2
controller
with extended PLC
functions and USB interface for communication.

Interface (as labeled)
Description
1
“MOTOR”
- Position, field and temperature sensor signals from motor
- Drive and bearing currents of the motor
Torque spec. for tightening of connector screws: Min. = 0.4 Nm, Max. = 0.6 Nm
2
“USER INTERFACE”
1 Digital Input
- Galvanic isolation with optocoupler
- Lowest input voltage for high level detection: min. 5 V
Typical 24 V / 16 mA, maximal 30 V / 20 mA
- Highest input voltage for low level detection: max. 0.8 V
- Minimum input resistance: R
IN
= 2.2 k
1 Digital Output
- Galvanic isolation with relay
- Relay: 1A / 30VDC, 0.3A / 125 VAC
1 Analog Input
- Analog current input: 4
– 20 mA
- 450 Ohm shunt input
3
“POWER INPUT”
DC power input -> 24 - 48 V
4
“Power on” Green LED
LED is on if supply voltage of signal electronics is present.
5
“Power Output off”
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.
6
“RESET” Button
Reset button of the controller stage. The button is sunk mounted and can be activated for example with a
small screw driver.
7
2-
Digit Display “Speed”
Rotational speed display in 100rpm
8
“UP” Button
Button for speed increasing and enabling of levitation
9
“DOWN” Button
Button for speed decreasing and disabling of levitation
10
“Firmware” Label
Firmware version and revision number
