Parallel Systems
If this is a parallel system, the CTs cannot be installed
on the load side of the active filter. Either the CTs are
improperly installed, the CTs are not functioning, or the
CT secondary wiring is not properly installed.
Single Unit
If you intend to install a single unit and the CTs on the
source side of the active filter, verify CT installation,
operation, or secondary wiring.
If you intend to install a single unit and the CT on the load
side of the active filter:
1.
Touch OK.
The unit asks if the load is regenerating.
– If so, the auto CT detection does not accurately
determine the CT configuration. Manually enter the
CT configuration.
– If the loads are not regenerative, touch NO
and Continue.
The unit asks if the displacement power factor of the
load operating at the time of the test was extremely low,
less than 0.5.
2.
Touch Yes or No as applicable for the connected loads
and then touch Continue.
The unit asks if the connected load at the time of the CT
detection was capacitive (having a leading power factor)
or inductive (having a lagging power factor).
3.
Select the appropriate load type and touch Continue.
The CT configuration is displayed based on parameters
selected. The DPF value and Leading or Lagging can be
compared to an external meter to verify accuracy of
the results.
