7.1.2 Warnings and Group Errors
Message Cause / Remedy
Check voltage Main voltage not yet applied.
Check line phases Main voltage is applied, but the motor is not connected or not properly connected, or the motor is properly
connected but no phase voltage is present.
Ready to start Device is ready to start (main voltage is applied and the motor is connected properly).
The motor will start when a start command is received.
Starting is active Motor is started in the set starting mode.
Motor is running Device is in bridging mode (bypass contactor). Starting completed.
Stopping is active Motor is stopped using the selected stopping mode.
Motor cool-down time active After overload tripping of the thermal motor model, it is impossible to start the motor for a defined period of time
(parameter: pre-charge time) to ensure that the motor can cool down.
Contact block cool-down time After overload tripping of the inherent protection, motor start is impossible for 30 s to allow the device to cool
down.

Warning
Error without restart
Error with restart
Cause / Remedy
No line voltage x Start command output even though the main voltage has not yet been applied.
Remedy: switch on line voltage.
Incorrect start conditions x 1. Error occurs without motor starting.
Cause:
- Motor is not connected correctly.
- Inside delta circuit wrongly configured.
- Ground fault present.
Remedy: Check and correct wiring (see inside delta circuit wiring suggestions).
2. Error occurs during starting.
Cause:
- Start voltage too high
- Breakaway pules set (unnecessarily): instable motor start
(Only set breakaway pulse if it is required. In the case of pumps, for example ,a breakaway
pulse often causes misfiring.)
If the idle time < 5 s since the last start, the 3RW44 starts with a higher start voltage. In
combination with a set breakaway pulse this can lead to "Incorrect start conditions".
Remedy: adjust the parameters or increase the idle time.
Phase failure L1 x Phase L1 missing or it fails while motor is running or it drops off.
Remedy: connect L1 or rectify cause of voltage drop.
Or: the motor that is connected is too small and the error message occurs immediately
after switching over to bridging mode.
Remedy: adjust rated operating current for connected motor or set it to minimum (if motor
current is lower than 10 % of the configured I
e
, the motor cannot be operated with this
starter).
