8.1
Testing the Installation
The EMX3 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 (refer to
Minimum and Maximum Current Settings
on page 82).
NOTE
When testing the soft starter with a small motor, set parameter 1A
Motor Full Load Current
to the minimum allowable
value.

5.
Use the
and
buttons to change the value.
6.
To save changes, press the button. The EMX3 will confirm the changes.
To cancel changes, press the button.
Simulation Tools
Software simulation functions let you test the soft starter's operation and control circuits without connecting the soft starter to mains
voltage. The EMX3 has three simulation modes:
•
The run simulation simulates a motor starting, running and stopping to confirm that the soft starter and associated
equipment have been installed correctly.
•
The protection simulation simulates activation of each protection mechanism to confirm that the soft starter and
associated control circuits are responding correctly.
•
The output signal simulation simulates output signalling to confirm that outputs and associated control circuits are
operating correctly.
The simulation tools are accessed via the Commissioning Menu. 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 security access code.
The default access code is 0000.
