6. Connect the terminal blocks and set the selector
switch according to the following table which re-
fers to the diagrams at the end of these instruc-
tions.
Single-pump operation
(the pumps are operating independently of
each other)
With operating indication
With fault indication
Alternating operation or standby operation
(use the intermediate cable supplied, see fig.
2)
Alternating Operation
Standby operation with pump 1 as
duty pump and pump 2 as standby
pump.
Note:
The selector switch must
not be set to alternating
operation.
Standby operation with pump 2 as
duty pump and pump 1 as standby
pump.
Note:
The selector switch must
not be set to alternating
operation.
Fault or operating indication for
twin-head pumps in alternating
operation:
If the signal output is to be used for
fault or operating indication, an in-
termediate relay must be used.
Figure F shows a single-phase
pump in alternating operation with
external fault indication if pump 2
or both pumps are faulty.
Fault or operating indication for twin-head
pumps in standby operation:
• If the signal output of the duty pump is to
be used for fault or operating indication, an
intermediate relay must be used.
• If the signal output of the standby pump is
to be used for fault or operating indication,
proceed as shown in fig. A or B.
7. In the case of alternating operation: Make a
functional test as described in section 9. Func-
tional test in the case of alternating operation.
8. Fit the terminal box covers.
