This action will reset both thermal models.
NOTE
The second thermal model is only active if Pr 11B Dual Thermal Model is set to 'Dual' and the starter is using the
NOTE
secondary motor set (a programmable input is set to 'Motor Set Select' and the input is active).
Resetting the motor thermal model may compromise motor life and should only be done in the case of emergency.

Simulations
Software simulation functions let you test the soft starter's operation and control circuits without connecting the soft starter to mains
voltage. The simulations are accessed via the Simulations menu.
The Digistart D3 has three simulation functions:
The protection simulation simulates activation of each protection mechanism to confirm that the soft starter and
associated control circuits are responding correctly. See Protection simulation for details.
The run simulation simulates a motor starting, running and stopping to confirm that the soft starter and associated
equipment have been installed correctly. The run simulation follows the protection simulations in the Simulations menu.
See Run simulation on page 68 for details.
The output signal simulation simulates output signalling to confirm that outputs and associated control circuits are
operating correctly. The output signal simulation follows the run simulation in the Simulations menu. See Output signal
simulations on page 69 for details.
The simulations are only available when the soft starter is in Ready state, control voltage is available and the keypad is active.
Access to the simulation tools is protected by the access code (see Access code on page 45).
The default access code is 0000.
NOTE
Protection simulation
To use the protection simulation:
1.
Open the Programming Menu and select Simulations.
2.
Use the
and
buttons to select the protection you want to simulate.
3.
Press and hold M to simulate the selected protection.
4.
The screen is displayed momentarily. The soft starter's response depends on the
Protection Action setting (parameter group 16).
5.
Use
or
to select another simulation, or press
Run simulation
You can end the simulation at any time by pressing
To use the run simulation:
1.
Open the Programming Menu and select Simulations.
2.
Scroll to Run Simulation and press M .
3.
Press START or activate the start input. The Digistart D3 simulates its pre-start
checks and closes the main contactor relay. The Run LED flashes.
If mains voltage is connected, an error message is shown. Remove mains
NOTE
voltage and proceed to the next step.
4.
Press M . The Digistart D3 simulates starting. The Run LED flashes.
5.
Press M . The Digistart D3 simulates running. The Run LED stays on without
flashing and the bypass contactor relay closes.
