Self-test (user-test)
With the Self-test (user-test), you can test correct functioning of the 3RW52 soft starter
(LEDs, current measurement, electronic motor overload protection).
Requirements
Activation options
Procedure - Activation with the RESET / TEST key
Depending on how long the RESET / TEST keys are held pressed, the following tests are
performed in the specified sequence. Thus, if the key is held pressed for longer than
8 seconds, all 4 tests are performed. If you press and hold the key for only 3 seconds, for
example, the first 2 tests are conducted.

SIRIUS 3RW52 Soft Starter
Equipment Manual, 04/2020, A5E35630451002A/RS-AE/005
The 3RW52 soft starter is in a fault-free condition.
Perform the test with the motor switched off.
Using the RESET / TEST key on the 3RW52 soft starter
3RW5 HMI High Feature (accessory)
Menu: "Diagnosis > Soft Starter > Self-test"
The 3RW5 HMI High Feature (LOCAL) has master control. Access protection to
3RW5 HMI High Feature is not active or has been reset.
Here the self-test (user-test) is run through completely.
Explanation
LED test
All LEDs are controlled.
Visual display of the position of the rotary coding switch
16 different positions are available for the rotary coding switch for setting the
rated operational current I
The table "Visual display of the position of the rotary coding switch" displays
the exact position of the rotary coding switch based on a combination of
5 LEDs.
You will find further information in chapter
Setting elements on the 3RW52 soft starter (Page 97).
Current detection test
The current detection is tested in all 3 phases.
In the case of 3RW52 soft starters with thermistor motor protection, the
thermistor evaluation unit is also tested.
Motor overload protection test
The entire control circuit is tested, including the contact blocks and the error
signaling output.
If the 3RW52 soft starter responds correctly, no overload trip occurs. This can
be reset immediately without a cooling-down period by pressing the TEST /
RESET key again.
