A fault indication can be reset in one of the following ways:
• By briefly pressing the button
or on the pump. This will
not change the setting of the pump.
A fault indication cannot be reset by means of
or if the
buttons have been locked.
• By switching off the electricity
supply
until the indicator lights
are off.
• By switching the external start/stop input off/on.
• By means of the R100, see section
When the R100 communicates with the pump, the red
indicator light will flash rapidly.
