6.
Press STOP or activate the stop input. The Digistart D3 simulates stopping. The
Run LED flashes and the bypass contactor relay opens.
7.
Press M . The Ready LED flashes and the main contactor relay opens.
8.
Press M to return to the commissioning menu.
Testing the installation
The Digistart D3 can be connected to a small motor for testing. During this test, the soft starter's control input and relay output
protection settings can be tested. This test mode is not suitable for testing soft starting or soft stopping performance.
The FLC of the test motor must be at least 2% of the soft starter's minimum FLC (see Minimum and maximum current settings on
page 11).
When testing the soft starter with a small motor, set Pr 1A Motor Full Load Current to the minimum allowable value.
NOTE
Output signal simulations
The following outputs are available to simulate:
Programmable relay A
Programmable relay B
Programmable relay C
Run relay
Low current flag
High current flag
Motor temperature flag
Analog output A
Analog output B
To test operation of the flags (motor temperature and low/high current), set an output relay to the appropriate function
NOTE
and monitor the relay's behaviour.
To use the signal simulation:
1.
Open the Menu and select Simulation.
2.
Use the
and
buttons to select a function to simulate, then press M .
3.
Use the
and
buttons to turn the signal on and off.
To confirm correct operation, monitor the state of the output.
4.
Press
to return to the simulation list.
The analog output simulation uses the
analog output terminals.
Attach a current measuring device to the analog output terminals. Use the
display. The current measuring device should indicate the same level of current as shown on the display.
If the input/output expansion card is fitted, the simulation can also be used to test the operation of Relays D, E, F and Analog
Output B.
