Appendix – A
Configuration/Bank/Switch Status
Level2 En/Dis
ENABLE
Allows Bank Failed Level 2 neutral current
measurements to determine capacitor bank switch
status.
Level2 Current Level
XXXX.X A
Neutral current detection setting from 1.0 to 200.0
A in .01 increments.
Bank Failed Delay
XXX Sec
Provides a 10 to 300 second time delay in 1 second
increments.
Prior OP Action
000
If the measured Level 2 neutral current is
determined to be a result of Prior Bank Operation
(detected within one minute of bank operation) this
setting allows the user to set up to three actions to
be taken by the control when the Bank Failed Delay
times out. They are:
• Retry Operation
• Reverse Operation and Block
• Reset Block
The sequence of actions is in the order above. See
the individual settings screens for "Retry Operation/
Number of Retry Attempts" and "Reset Block/Block
Reset Time Delay".
No of Retry Attempts
X
Setting establishes the Number of Retry Attempts
(1 to 9) that the control will attempt when "Prior OP
Action – Retry Operation" is activated.
Block RST Time Delay
XX Hrs
When "Prior OP Action – Reset Block" is activated,
this setting provides a timed reset of the block
activated by the "Reverse Operation and Block
selection. This setting can be set from 1 to 72 hours.
No Prior Op En/Dis
ENABLE
Enables the "Open Lockout Time Delay".
Open Lockout T Delay
XXXX
When enabled and if the measured Level 2 neutral
current is determined to be a result of No Prior
Bank Operation (detected greater than one minute
after bank operation) this timer starts timing (1 to
4320 Minutes) when the Bank Failed Delay timer
has timed out. When this timer times out it initiates
an Open command to the capacitor bank and locks
out any further operation.
Lockout RST En/Dis
ENABLE
Enables the "Lockout Reset Time Delay".
Lockout RST Delay
XXXX
When enabled and if the measured Level 2 neutral
current is determined to be a result of No Prior
Bank Operation (detected greater than one minute
after bank operation) this timer starts timing (1 to 72
Hours) when the "Open Lockout Time Delay Delay"
timer has timed out. When this timer times out it
removes the Open Lockout and allows capacitor
bank operation.
