The HCYC prompt stands for “Half Cycle Line Loss.”. The theory as explained to me by Watlow was that if supply voltage on any phase was disrupted to the degree that it lost half the cycle, meaning the positive or negative half of the sine wave, the resulting DC component could have caused damage to the transformer. As a matter of fact, these very instructions originally stated that the user should not disable the HCYC function when the SCR was firing into a transformer. I retyped it and added a few notes to clarify the steps to get to the setup and factory pages based on feedback from some users who went through the process. I did speak with Watlow in March and asked them again to confirm that we should ignore the note about not disabling HCYC when using a transformer, and they did confirm without hesitation.
