Problem shooting
If the pump does not start to operate or stops the operation abruptly, please
proceed as follows:
Try to liberate the micro annular gear pump:
by turning the potentiometer knob back and forth or by sending an analog
via the control software
through the micro annular gear pump
by changing the operating direction of the pump.
If these measures turn out to be ineffective, please contact the service staff of
HNP Mikrosysteme (see chapter 14) and send the pump back to the
manufacturer for inspection.
You should under no condition try to dismantle the pump by yourself. This
Warning
may cause damage to the pump components and consequently annul your
warranty claims.
