Wrong phase sequence
If the connection to the soft starter is not done in the correct sequence (L1,
L2, L3), the RSBD will trigger the wrong phase sequence alarm and the motor
will not be started.
N/A
1
User intervention is required to change the wiring sequence to recover alarm.
• Check that wiring on L1, L2, L3 is in the correct sequence.

Line voltage out of range
At every power-up the RSBD automatically detects the supply voltage level
and determines whether it is working on a 220, 400, 480* or 600* V supply.
The under- or over- voltage alarm level is then set at a level of -20% and +
20% (from the measured supply voltage level) respectively.
If the supply voltage level is out of these limits for more than 5 seconds then
the line voltage out of range alarm will be triggered.
* Applies to RSBD60 models.
Note: for RSBD60 over-voltage alarm level (for the case of a 600V supply) is
675V (600V + 11%).
Note: RSBD 45mm models have a fixed level for undervoltage (174VAC)
and for over-voltage (466VAC). The alarm will trigger when the voltage level
measured is outside these limits for at least 5 seconds.
5 minutes

The alarm will self-recover after 5 minutes from when the supply voltage is
within limits.
• Check supply voltage level across L1, L2, L3 terminals.
• Make sure that you are not using a RSBD40 model on a supply voltage >
440 VAC.
4
Frequency out of range
If the frequency measured by the RSBD is >66.5Hz and <44.5Hz for at least
1 second, this alarm will trigger.
5 minutes
N/A
Check for any disturbance on the voltage network. The voltage waveform may
be disrupted when unfiltered variable frequency drives are used.
• In the case where variable frequency drives are present, ensure that proper
EMI filters are installed.
