Horner XL4

2 posts in this topic

Greetings,

I'm having trouble with a Horner XL4 power cycling itself when 120 V is switched with its relay outputs. I have tried both polarities and slowing down the switching quite a bit. The unit appears to power cycle even when the relay is not switching, and only when 120 V is applied to the relay outputs. I am driving a control 24 - 230 V AC/DC light off an on once a second or so, with the identified/neutral attached to the 120 V AC / 12 V DC PSU.

Would anyone be able to guide me into what could be causing this?

Thank you.

I do not have an answer for you but will share a similar experience. Not only would ours cycle power, but it would also lose its program. You can try installing MOVs, isolating the PLC power or other means of reducing electrical noise but we replaced ours with another brand.
