OIt • Overcurrent time delay R/W<br />
Adjusts the time delay linked with the parameter OId.<br />
(1)Only available when Advanced mode LAC page 50 is set to On.<br />
*: Write only when the soft starter is stopped<br />
0.0 .. 5.0<br />
by increment of 0.1<br />
Ubd • Unbalance threshold R/W Off,10..100 (% of In) 25<br />
Trips the soft starter in case of motor current unbalance, between 2 or 3 phases.<br />
This is depending also to the soft starter range.<br />
This is linked with the unbalance time delay Ubt.<br />
Adjusts the motor current unbalance. Combined with unbalance delay Ubt.<br />
Note: Trip message is PHbd.<br />
Ubt • Unbalance time delay<br />
Adjusts the time of unbalance threshold Ubd.<br />
Grdd • Ground leakage current threshold<br />
Only in the SH31-.../6 ranges<br />
Automatically set to oFF on SH31-.../4 range<br />
Combined with Ground leakage current time delay (Grdt).<br />
Note: Trip message is GrdF.<br />
Grdt • Ground leakage current time delay<br />
Adjusts time delay of ground leakage current threshold Grdd.<br />

- 3 2 1: reverse (L3 - L2 - L1)<br />
- 1 2 3: Forward (L1 - L2 - L3)<br />
- Off: not monitoring<br />
If the line phases are not in the order confugured, the soft starter trips and displays PIF.<br />
Note: When dLtA is set to dLt (the soft starter is connected Inside delta connection), PHr is forced to 123.<br />
In this case, PHr value is not used and is not relevant.<br />
