Relay module
The relay module is an optional extra for single-head
and dual-head pumps.
The module enables direct connection of the pump to
line voltage and an external operating or fault indication
device. The signal output for an external signal device
can be set to activate during operation or fault by means
of the selector switch.
The signal outputs of relay modules in dual-head pumps
can be interconnected so that the pumps are operating
alternately as duty pump and standby pump.
The pump is connected directly to line voltage as the
pump incorporates overload protection at all three
speeds. If the pump has been cut out by the thermal
overload switch, it will restart automatically when it has
cooled to normal temperature
.
Indicator lights on relay module
The indicator lights on pumps with relay module have
more detailed operating and fault indications.
All pumps with relay module are equipped with a green
and a red indicator light. Their functions are as shown in
the table below.
Signal output of relay module
The relay module is equipped with a signal output for
external operating or fault indication.
By means of the selector switch, the output can be used
as:
• Operation signal output between terminals 2 and 3
or
• Fault signal output between terminals 1 and 3.
Functions of indicator lights and signal output
Note: Pumps with relay module must not be connected
to a frequency converter.
