6.7.1 Fault signal module
Via an internal relay, the fault signal module gives
access to a potential-free fault signal.
In addition to this fault signal output, the module has
four inputs for external signals for the forced-control
functions:
• Start/stop of pump.
• Max. curve duty.
• Min. curve duty (night-time duty).
• External analog control of head or speed from an
external 0-10 V signal transmitter.

Note:
• If no external on/off switch is connected, the con-
nection across terminals 7 and 8 should be main-
tained.
• If the 0-10 V input is used (terminals 11 and 12),
there must be a connection across terminals
7 and 9 (the input for the min. curve must be
closed).
• All cables used must be heat-resistant up to at
least +85°C.
• All cables used must be installed in accordance
with EN 60 204-1.

• Wires connected to
- outputs 1 to 3,
- inputs 7 to 12 and
- supply terminals
must be separated from each other and
from the supply by reinforced insulation.
• All leads connected to a terminal block
must be tied up at the terminals.
