Restoring the factory settings with the MODE and RESET / TEST keys

Requirements
● Make sure that the motor is switched off and 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 at the 3RW50 soft starter.
● The 3RW5 communication module must be isolated from the 3RW50 soft starter.
Procedure
1. Start the restoration of the factory settings by pressing the MODE key longer than 2 s
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 s.
After 2 s, the STATE / OVERLOAD LED begins to illuminate red.
After 10 s the STATE / OVERLOAD LED goes out and switches back to displaying the
motor operating state (e.g. flashing yellow if there is no supply voltage).
3. Release the MODE and RESET / TEST keys.
Result
The factory setting of the 3RW50 soft starter has been restored.
Note the effects of the factory settings described in Chapter Effects of the factory setting
(Page 189).
