Chapter IV Keyboard Operation and Running
4.1 Selection of Operation Mode
The Product is provided with three control modes, including keyboard running,
terminal running and self-running upon power-up. Users can select corresponding
control mode according to field environment and working needs. See 5.1 for specific
selections.
4.2 Test Run and Inspection
4.2.1 Precautions and inspection prior to test run
1. Don’t turn power on until the front cover is installed and Don’t remove the
outer cover when power is on; otherwise, electric shock will be caused.
2. Don’t get close to frequency inverter or load when restart is selected, as the
device will restart suddenly after it is just stopped. (Even if frequency inverter
restarts, its mechanical system can ensure personal safety). Otherwise, personal
injuries will be caused.
3. As stop button will become not working after function setting, a separate
emergency stop button should be installed; otherwise, personal injuries will be
caused.
1. Don’t touch the radiator or resistor since it is hot; otherwise, burns will be
caused.
2. As low-speed running can easily become high-speed running, confirm the safe
working range of motor and mechanical equipment before running; otherwise,
personal injuries and equipment damages may be caused.
3. If necessary, install a band-type brake separately; otherwise, person injuries
will be caused.
4. Don’t change wiring during operation; otherwise, the equipment or frequency
inverter will be damaged.
In order to ensure safety, mechanical coupler shall be unhooked before initial
running, so that the motor can separate from mechanical equipment. If the motor and
mechanical equipment are coupled before the initial running, special attention
should be paid in to prevent possible dangers. Inspect the following contents before
test run:
A Whether leads and terminals are connected correctly.
B Whether there is lead residues that may cause short circuit.
C Whether screw terminals are tightened firmly.
D Whether the motor is installed firmly.
4.2.2 Test Run
When the system gets ready, turn on power supply and inspect whether the
frequency inverter is normal. Digital operation keyboard is lighted up when the
power supply is turned on. If any problem is found, turn off the power supply
immediately.
After the power supply is turned on, the frequency inverter operates
automatically (default factory settings) after a 30-second delay. Observe water outlet
of water pump. If the quantity of outlet water is normal, then the test run succeeds; if
it is low, exchange two motor wires randomly and then run again.
