Environment

H909HV-S6 Current Transformer

Cause

The issue is due to incorrect wiring between the current transformer and the DDC controller.

The installation instructions may appear to indicate that four connections are required to the DDC controller. However, this is not correct—only two connections are necessary.

Resolution

To resolve the issue:

1. Review the wiring diagram in the installation instructions carefully.
2. Ensure that only two connections are made between the CT and the DDC controller:
   • The status output has two terminal sets, but only one connection is required from each set.

     

3. Correct the wiring to match the proper configuration.
