Digistart D3: User Guide

Issue: G
NOTE
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 secondary motor set (a programmable input is set to 'Motor Set Select' and the input is active).
CAUTION
Resetting the motor thermal model will compromise thermal model protection and may compromise motor
life. Only reset the thermal model in an emergency.
8.9.2 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 87
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 88
for details.
The simulations are only available when the soft starter is in Ready state, control voltage is available and the keypad
is active.
NOTE
Access to the simulation tools is protected by the access code (see
Access Code
on page 57).
The default access code is 0000.
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).

to exit.
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
