Diagnosis state
Shows all active prewarnings and faults. You can acknowledge
faults here. A 3RW5 PROFINET High Feature communication mod‐
ule also shows the device state.
Additional information
You will find further information on the diagnostics of the 3RW5 communication module in the
Equipment Manual for the respective 3RW5 communication module.

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
e
is displayed. The thermistor motor protection is tested for short
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)
