You will find further information on the diagnostics of the 3RW5 communication module in the
Equipment Manual for the respective 3RW5 communication module.
9.9 Self-test (user-test)
With the self-test (user-test), you can test correct functioning of the 3RW55 and 3RW55 Failsafe
soft starters (LEDs, current measurement, electronic motor overload protection, F‑RQ failsafe
signaling output).
Requirements
• The 3RW55 or 3RW55 Failsafe soft starter is in the error-free condition.
• Perform the test with the motor switched off.
Activation on the 3RW5 HMI High Feature
• 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.
Operating principle
Start the self-test (user-test) via the 3RW5 HMI High Feature. The self-test (user-test) is
performed as follows:
• LED test
All LEDs are controlled (3RW5 soft starter and 3RW5 HMI High Feature).
• Current measurement test
The current detection is tested in all 3 phases.
On the display of the 3RW5 HMI High Feature, the average phase current (%) relative to the
rated operational current I
circuits and overload.
• Test of the electronic motor overload protection
The entire control circuit is tested, including the switching elements and the error signaling
output.
• Test of the F‑RQ failsafe signaling output (output 41, 42) on the 3RW55 Failsafe soft
starter (function test)
