• If the capacitor bank just Opened and the
Neutral Current results in the capacitor
bank reversing and blocking, and a THD
Trip is concurrently required to Trip and
Lockout, then the THD Trip and Lockout
will be ignored and the capacitor bank
will remain Closed and blocked. In
this scenario, it is better to leave the
capacitor bank Closed and remove the
unbalance rather than Trip due to high
THD. Should the THD conditions remain
and the Neutral Current Block clear in this
scenario, then the capacitor bank would
Trip and Lockout due to THD.
Manual Control
If the control is in Manual and either Voltage or
Current THD increases to a level that results in it's
associated THD alarm, the alarm will be in effect, but
no Trip is allowed and Manual operation will not be
prevented. Consider the feature in standby waiting
to Trip the capacitor bank and Lockout if it should
be placed back in Automatic or Remote Manual.
Setting Voltage and Current THD Trip and
Lockout Settings from the HMI
To set the Voltage and Current THD Trip and Lockout
settings perform the following:
1.
Press the Down Arrow (CNFG Hot Button)

not, a valid Level 2 Access Code will be
required to be entered as described in
Step 7.
