4G – Phase Sequence
Options:
Any Sequence
Positive Only (default)
Negative Only
Description:
Selects which phase sequences the soft starter will allow at a start. During its pre-start checks, the starter
examines the sequence of the phases at its input terminals and trips if the actual sequence does not match the
selected option.
4H – Current Imbalance
Range:
10% - 50%
Default:
30%
Description:
Sets the trip point for current imbalance protection.
4I – Current Imbalance Delay
Range:
0:00 - 4:00 (minutes:seconds)
Default:
5 seconds
Description:
Slows the MVE's response to current imbalance, avoiding trips due to momentary fluctuations.
NOTE
The MVE will display a Current Imbalance trip only when phase loss at the supply terminals occurs during Run
mode. When a phase loss occurs during other modes of operation, the MVE will trip on Motor Connection.
4J – Frequency Check
Options:
Do Not Check
Start Only
Start/Run
Run Only (default)
Description:
Determines when and if the starter will monitor for a frequency trip.
4K – Frequency Variation
Options:
± 2 Hz
± 5 Hz (default)
± 10 Hz
± 15 Hz
Description:
Selects the soft starter's tolerance for frequency variation.
4L – Frequency Delay
Range:
0:01 - 4:00 (minutes:seconds)
Default:
5 seconds
Description:
Slows the MVE's response to frequency disturbances, avoiding trips due to momentary fluctuations.
NOTE
If the mains frequency drops below 35 Hz or rises above 75 Hz, the starter will trip immediately, irrespective of the
settings for Frequency Trip parameters.
4M – Restart Delay
Range:
00:01 - 60:00 (minutes:seconds)
Default:
30 minutes
Description:
The MVE can be configured to force a delay between the end of a stop and the beginning of the next start.
During the restart delay period, the display shows the time remaining before another start can be attempted.
4N – Motor Temperature Check
Options:
Do Not Check (default)
Check
Description:
Selects whether the MVE will verify the motor has sufficient thermal capacity for a successful start. The soft
starter compares the motor's calculated temperature with the temperature rise from the last motor start and
only operates if the motor is cool enough to start successfully.
