Test result
The test results are provided in the following tables. If the 3RW5 soft starter does not
respond as shown in the tables below during the function test, check the external
connections, their function, and the wiring. If the error persists even though the connections
are correct, the 3RW5 soft starter must be replaced.
If a 3RW5 HMI is connected to the 3RW5 soft starter, the 3RW5 indicates "Motor overload
tripping" when it passes the function test. If the 3RW5 soft starter does not pass the function
test, the 3RW5 HMI indicates a device error.
