To stop the pump permanently, press the "Stop" button. If the pump was out of
operation for some extended period of time, the steps described above have to
be repeated for a renewed putting into operation. The electrical pumps of the
T.I.P. HWA series are equipped with an integrated thermal motor protection fea-
ture. In the case of overload, the motor will switch off independently and on again
after cooling down. For possible causes and their elimination, please refer to the
“Maintenance and troubleshooting” section.
8. Functioning of the electronic pump control system
8.1.
General information
The electronic pump control feature acts as a function of the pressure and the
water flow rate. On the one side, it will cause the automatic cutting-in or cutting-
out of the pump when the water tap or any other consumer component is opened
or closed. On the other side, the electronic pump control will trigger the automatic
cut-out feature of the pump in the case of dry running or absence of water, which
means if the volume of the water being discharged is insufficient or if no water is
being discharged at all. This will prevent damage to the pump caused by over-
heating.
8.2.
Functioning
Opening a water tap or any other consuming component will lead to a drop of the
pressure inside the pipe system. As soon as the preset cut-in pressure is
reached, the electronic pump control will start the pump. Following the closing of
the consuming component, the pump will continue to run until the pressure in the
system stops to raise, subsequently it will cut the pump out. The pipe system will
then be subject to the max. attainable pressure of the pump.
The current working pressure of the device is indicated by the blue light on the
right side of the control panel. As soon as the pump stops, the blue light switch
off after a few seconds.
8.3.
Cutting out in the case of dry running or absence of water
In the case of dry-running or the absence of water, the electronic pump control
will cut the pump out. In addition, the red “Fehler” (Error) warning indicator will
light up. This protection feature will prevent another automatic start-up of the
pump. To resume operation, the “Start Pump” key of the electronic pump control
has to be depressed. Before doing so, please make sure to eliminate the cause
of the dry running.
