Restoring the factory settings with the MODE and RESET / TEST keys
Requirements
• 3RW51 soft starter from firmware version V2.0
• Make sure that the motor is switched off and that you do not start the motor while restoring
the factory settings. To ensure the quickest and most fault-free restoration of the factory
setting, it is recommended that you disconnect the main voltage (operating voltage) at the
3RW51 soft starter.
• The 3RW5 communication module must be isolated from the 3RW51 soft starter.
Procedure
1. Start the restoration of the factory settings by pressing the MODE key longer than 2 seconds
until the STATE / OVERLOAD LED flickers green.
Press and hold the MODE key.
2. Simultaneously press the RESET / TEST key down for at least 10 seconds.
After 2 seconds, the STATE / OVERLOAD LED begins to illuminate red.
After 10 seconds the STATE / OVERLOAD LED goes out and switches back to displaying the
motor operating state (e.g. flashing yellow if there is no main voltage (operating voltage)).
3. Release the MODE and RESET / TEST keys.
Result
The factory setting of the 3RW51 soft starter is restored.
Note the effects of the factory settings (Page 155).
