Functions
8.19 Test mode
Setting options
Automatic starting in test operation (test with a small load)
Can cause death or serious injury.
The 3RW55 and 3RW55 Failsafe soft starters immediately continue to operate with the values
set by the control once test operation has been activated. Outputs are activated when the ON
condition is met.
Take appropriate measures to prevent unintentional starting and to ensure a defined start of
the system.

Simulation

Operating principle
The test mode function "Simulation" is useful for commissioning and troubleshooting because
any situations can be tested without great effort, e.g. wiring modifications, connection of
external devices or interventions in the PLC.
With the test mode function "Simulation", the 3RW55 soft starter virtually simulates the motor
operating states (starting, running, stopping) without main current. The 3RW55 soft starter

Description
The 3RW55 or 3RW55 Failsafe soft starter switches to the test mode function "Test with
small load".
The test mode function "Test with small load" is terminated. The 3RW55 or 3RW55
Failsafe soft starter exits the test mode and switches back to the parametrized operating
mode.
