9.4 Protection Simulation

NOTICE
Protection simulation is protected by the security access
code.
To test the operation and control circuits of the soft starter
without connecting it to mains voltage, use the software
simulation functions.
The protection simulation feature enables the soft starter
to confirm that it responds correctly and reports the
situation on the display and across the communication
network.
To use the protection simulation:
1. Open the Main Menu.
2. Scroll to Protection Sim and press [OK].
3.
To select the protection to simulate, press [
▼
[ ].
4. To simulate the selected protection, press [OK].
5. The screen is shown while [OK] is pressed. The
soft starter response depends on the protection
action setting (parameter group 16 Protection
Actions).
6. To return to the simulation list, press [Back].
7.
To select another simulation, press [
press [Back] to return to the Main Menu.

NOTICE
If the protection trips the soft starter, reset before
simulating another protection. If the protection action is
set to Warn or Log, no reset is required.
If the protection is set to Warn & Log, the warning
message can be viewed only while [OK] is pressed.
If the protection is set to Log only, nothing appears on
the screen but an entry appears in the log.

9.5 Output Signal Simulation

NOTICE
The security access code protects the output signal
simulation.
The LCP allows simulation of output signaling to confirm
that the output relays are operating correctly.

NOTICE
To test operation of the flags (motor temperature and
low/high current), set an output relay to the appropriate
function and monitor the relay behavior.
