6.6 Indicator lights
The two indicator lights are used for fault and operat-
ing indication.
For position on pump, see fig. 11, section 7.2 Control
panel.
Note: When the R100 remote control communicates
with the pump, the red indicator light will flash rap-
idly.
Functions of indicator lights:
See also section 8. Fault finding chart.
6.7 External fault indication
The pump incorporates a fault signal output for a po-
tential-free fault signal via terminals 2 and 3.
Functions of signal output:
The fault signal output is activated when the pump
registers a fault. The fault signal relay is activated to-
gether with the red indicator light on the pump.
Resetting of fault indications:
A fault indication can be reset in one of the following
ways:
• Briefly press “+” or “–” on the pump. This will not
influence the pump performance set.
• Briefly switch off the electricity supply to the
pump.
• By means of the R100, see section 7.3 R100.
The fault indication cannot be reset until the cause of
the fault has disappeared.
