Analog Interface
(Hei-FLOW Advantage and Hei-FLOW Precision only)
To operate pump externally an analog
interface is located at the backside of
device.
Via this interface the speed can be set.
The socket is protected against splash
water with a screw cap.

▪ PIN 1 = +5 V
▪ PIN 2 = Start /Stop
▪ PIN 3 = 0-10 V
▪ PIN 4 = Direction of rotation

▪ TTL-level 0 V = clockwise rotation, TTL-level 5 V = counter-clockwise rotation
▪ TTL signal 5 V switches pump on and off.
This function is available all the time (also in internal mode).
▪ For triggering direction of rotation and ON/OFF function, a 5 volts pin is available in
the interface connector which allows potential-free switching.
▪ The analog interface is recognized at a level of 0.2 volts or a 4 mAmps current.
▪ Hei-FLOW Precision: This mode is confirmed by “EA” in the display. As long as the
pump drive is controlled via analog interface, the display is inactive and “Start/Stop”
key will be the only active key on the device.
Digital Interface
(Hei-FLOW Precision only)
You can connect the device to a PC.
In addition to an analog interface a
RS 232 digital interface is located at the
backside of device.
