A short circuit can lead to damage to

The interface adapter comes with a mains adapter for the
power supply.
The pump is to be connected to the signal output at the
terminals 5 and 6 (see table below).
The VBus /PWM interface adapter comes with a pre-con-
®
nected VBus ® cable. The second pair of VBus
be used for the connection of another VBus

The jumper to the right of the terminals is used for deter-
mining whether a PWM signal or 0-10 V signal is to be used.
The jumper poles are indicated with A, B and C.
Jumper position A+B = PWM signal (factory setting)
Jumper position B+C = 0-10 V-Signal
Changing the signal type:
Î Pull the jumper out of the slot and insert it according
to the desired signal type.
By means of the two-pole jumper slot to the left of the
DIP switches, the PWM signal generated can be inverted.
Jumper not connected:
Jumper connected (factory setting):
Changing the factory setting:
Î To disconnect the jumper, take it off its initial position
and relocate it onto only one of the pins.
The 0-10 V signal is not affected by the signal inversion.
The minimum pump speed is 30 % (see fi gure to the left).
Note
Whenever the pump is switched on, it will be
run at 100 % speed for a few seconds before the
fl exible pump speed control is effected.
