tests the wiring, the behavior when the monitoring function responds and the soft starter
parameterization of the plant for correct functioning. In simulation of the motor operating
states, all functions and messages of the 3RW55 soft starter are executed and displayed as in
normal operation. The error monitoring functions that are to be attributed to a missing main
supply are not active.
If, during an active "Simulation", the 3RW55 soft starter detects the presence of main current, a
fault is generated with a shutdown command and the message text "Line voltage for test not
permissible". This safety measure prevents a connected motor from being switched on
accidentally. After disconnection of the 3RW55 soft starter from the main supply, this error
message can be acknowledged with Reset. The "Simulation" remains active until the test mode
function is deactivated.
The motor and intrinsic device protection functions of the 3RW55 soft starter remain active
according to their parameterization and are not influenced by the test mode function
"Simulation".
Validity
This function is not available for the 3RW55 Failsafe soft starter.
Requirements
• 3RW55 soft starter from firmware version V2.0
• The test mode functions, e.g. "Test with small load" or "Self-test (user-test)" are deactivated.
• The 3RW55 soft starter is disconnected from the main circuit.
• The motor is switched off.
• The 3RW55 soft starter must be in Test mode (Page 221). In test mode, the "RN" LED flashes
green on the 3RW55 soft starter.
Note
Activating test mode
If you activate or deactivate the "Simulation" on the 3RW5 HMI High Feature, you will
automatically also switch to Test mode or Normal operation. For activation and deactivation
on the 3RW5 HMI High Feature, the 3RW5 HMI High Feature must have master control.
