1. Password 0000 0000 to zzzz
This setting specifies to enter the set password
2. Trigger Position 50% 10% to 90% step 1%
This setting sets the trigger point as a percentage of the duration. For example, the default setting, which is set to 50% (of 1.0s) gives 0.5s
prefault and 0.5s post fault recording times.

This setting is used to enable or disable the 2nd Harmonic blocking of the overcurrent protection.
2. 2ndHarm Thresh 20% 5% to 70% step 1%
This setting is used to specify the 2nd Harm Threshold value. If the level of 2nd harmonic/fundamental in any phase current or neutral
current exceeds the setting, the overcurrent protection will be blocked as selected.
3. I>lift 2H 10.00*In 4 to 32*In step 0.01*In
The 2nd harmonic blocking is applied only when the fundamental current is above 2nd Harm Thresh and below I> lift setting. The reset
levels are 95% of these thresholds.
