Test Operation
Run the pump for a short time (3–10 minutes) and confirm the
following:
Using an ammeter (clamp-on type), measure the operating current at the L1 and L2 phase wires
on the terminal.
COUNTERMEASURE:
If the operating current exceeds the rated
value, pump motor overload may be a cause. Make sure the pump
has been installed under proper conditions as described in
Installation
.
Using an AC voltmeter (tester), measure voltage at the terminals. Supply voltage tolerance:
within ±5% of rated voltage.
COUNTERMEASURE:
If the supply voltage is outside the tolerance,
possible causes are the power supply capacity or an inadequate
extension cable. Look again at the wiring diagram and make sure the
conditions are proper.
In case of very excessive vibration, unusual noise or odor, turn off the
power immediately and consult your nearest dealer or Wacker
Neuson representative. Continuing to operate the pump under
abnormal conditions may result in electrical shock, fire, or current
leakage.
WARNING
Injury or other major accident hazard.
To avoid possible recoil, do not operate the pump while it is suspended in the air.
WARNING
Electric shock hazard.
To avoid a current leak, do not start the pump when people are standing next to it.
