8.5. Instruments not allowed
Note:
The use of the following instruments is not
allowed during fault finding:
Note:
When measuring, use RMS-instruments.
8.6. Checking of motor and cable
1. Supply voltage
Measure the voltage (RMS) between
line and neutral. Connect the voltmeter
to the terminals at the connection.
When the motor is loaded, the voltage
should be within the range specified in
section 5, Technical Data.
Large variations in supply voltage
indicate poor electricity supply, and
the BMQE should be stopped until the
defect has been remedied.
2. Current consumption
Measure the current (RMS) while
the pump is operating at a constant
discharge head (if possible, at the
capacity where the motor is most
heavily loaded).
For maximum current, see nameplate.
If the current exceeds the full load
current, there are the following
possible faults:
• Poor connection in leads, possibly
in the cable joint.
• Too low supply voltage, see item 1.
