Operation PS (3-Phase) Series
wc_tx000131gb.fm 20
4.5.6 Operate the pump for a short time (3 to 10 minutes) and perform the
following checks:
Operating current
Using an AC ammeter (clamp), measure the current at the phases U,
V, and W that are connected to the terminal board.
COUNTERMEASURE: Because an overload condition may be
present at the motor if the operating current exceeds the rated current,
refer to Section
Installation
in this manual for procedures on reverting
the motor to the correct state.
Operating voltage
Use an AC voltmeter (tester) to measure the voltage at the terminal
board.
Power supply voltage tolerance = within ±5% of the rated voltage
COUNTERMEASURE: If the power supply voltage deviates from the
tolerance value, the deviation may be caused by the capacity of the
power supply or the extension cable that is used. Refer to Section
Electrical Wiring
in this manual to provide correct voltage.
Vibration
If the pump generates a considerable amount of vibration, noise, or
smell, disconnect the power supply immediately and contact the dealer
where you purchased the equipment, or the Wacker sales office in
your area.
