6.8 External fault signal

The pump incorporates a signal output for a poten-
tial-free fault signal.
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, pos. 2, fig. 20, on
the pump.
Function of signal output:

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 7.4 R100 dis-
play overview.
Before the pump can revert to normal duty, the fault
cause must be eliminated.
If the fault disappears by itself, the fault indication
will automatically be reset.
The fault cause will be stored in the pump alarm log.
The latest five faults can be called up by means of
the R100.

6.9 Indicator lights

For position on pump, see fig. 20, section 7.2 Control
panel.
The indicator lights, pos. 2, are used for operating
and fault indication. Furthermore, they indicate
whether the pump is externally controlled.
Note: When the R100 remote control communicates
with the pump, the red indicator light will flash
Normal duty
rapidly.
The function of the operating and fault indicator
lights can be found in section 8. Fault finding chart.
Stop
The indicator light for external control is on
if
• the pump control panel is inactive,
• the pump is in constant-curve operating mode,
• the temperature influence is active or
• the pump is controlled by an external unit.

6.10 Expansion modules

The pump can be fitted with an expansion module
enabling communication with external signals (signal
transmitters).
Two types of expansion module are available:
• GENI module.
• LON module.
The fitting of a module is illustrated in fig. 14.
Open the terminal box cover and fit the module, see
!, " and #.
Before removing the terminal box cover,
make sure that the electricity supply has
been switched off for at least 5 minutes.
