Internal error
The dosing pump carries out a self-check, which switches off the pump if no stroke has been carried out two seconds after motor start-up (e.g. if back pressure is too high) or if the
proximity switch (stroke sensor) does not respond (display E-2). The alarm is reset by pulling out the mains plug.
The functions of the LEDs and built-in warning alarm relay are shown in the following table:
