Controlling the MD 1 VARIO-SP

Connecting the cable:

As set at the factory, the pump is designed for operation

with a control signal; i.e., without a control signal, the pump

does not start!

To operate the pump without a control signal, change the

settings on the circuit board (see below)!

NOTICE

External setting of the motor speed via PWM

(factory set)

PWM

(pulse-width modulation; Low: 0V - 0.5V; High: 5V - 24V max.)

frame frequency: 100Hz to 1.5kHz

0% to 100% PWM: Linear increase of the motor speed:

0 rpm (at 0% PWM) to 2400 rpm (at 100% PWM)

Pump will run smoothly only at motor speeds higher

than 200 rpm.

Example: Pulse-width at a frame frequency of 1 kHz

and at 700 rpm motor speed: 0.3 ms

Selecting the control signal input:

(PWM / voltage / internal setting)

To select a control signal input other than the factory set one (PWM), the

control line at the terminal board has to be reconnected.

The control line contains four differently colored wires.

wire in control line

assignment

red

+24V DC (supply voltage, max 7A)

blue

GND (24V)

white

PWM: 5V to max. 24V or

voltage input: 0V to 10V DC (max. 24V)

(depending on the control signal input for

motor speed)

black
