7i96s and Hypertherm CPC port THCad2

Tying in the THCad2 to the 7i96s today and noticed that pins 12 and 14 of the CPC port which are for arc ok / Transfer have power on them 14 has 18vdc and 12 has 24vdc. Kept wondering why I was getting the ARC ok LED on the 7i96s to light up. Is this normal as I was under the impression 12 and 14 were just basically part of an internal relay in the Hypertherm so technically the only power there should be what ever I supply to it?? No where in my system do I have those voltages as it is 50vdc, 12vdc and 5 vdc these power readings are also present when there is no power applied to the Hypertherm. So im guessing somehow im applying voltage to it through one of the other connections and its multiplying??

Ok power had been applied to the hypertherm prior to testing but an hour later the power on those pins seems to be slowly dropping off like there is a cap there at the relay?
