Restoring the factory settings with the MODE and RESET / TEST keys
Requirements
Ⴠ
3RW52 soft starter from firmware version V2.0
Ⴠ
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 3RW52 soft starter.
Ⴠ
The 3RW5 communication module must be isolated from the 3RW52 soft starter.

2 seconds until the STATE / OVERLOAD LED flickers green.
