Resetting of fault indication
A fault indication can be reset in one of the following ways:
• Briefly press 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.
• Switch off the power supply until the indicator lights are off.
• Switch the external start/stop input off and then on again.
• Use the R100. See section 10.1.3 Fault indications.
When the R100 communicates with the pump, the red indicator
light will flash rapidly.
