Instruments not allowed:
Note: The use of the following instruments is not allowed during fault
finding:
Note: When measuring, use RMS-instruments.
Checking the motor and cable:
Environment
During handling, operation, storage and transport, all environment
regulations dealing with the handling of hazardous materials must be
observed.
When the pump is taken out of operation, it must be ensured
that no hazardous material is left in the pump and in the riser
pipe, which can be injurous to persons and the environment.
Disposal
Disposal of this product or parts of it must be carried out according to the
following guidelines:
1. Use the local public or private waste collection service.
2. If such waste collection service does not exist or cannot handle the
materials used in the product, please deliver the product or any
hazardous materials from it to your nearest GRUNDFOS company or
service center.

Resistance
Test
High-voltage
Test
Measure the voltage L1
(RMS) between phase
and L2. Connect the
voltmeter to the terminals
at the connections.
The voltage should, when the
motor is loaded, be within the
range specified on Page 4, large
variations in supply voltage
indicate poor electricity supply,
and the pump should be stopped
until the problem has been
corrected.
Measure the current (RMS)
while the pump is operating
at a constant discharge
head(if possible, at capacity
where the motor is heavily
loaded). For maximum
current, see motor
nameplate.
If the current exceeds the full load
current, there are the following
possible faults:
Poor connection in the leads,
possibly in the cable joint.
Too low supply voltage, see item 1
on Page 13.
