Thanks for your input everyone. My problem is that we installed one HD/LM operator already. I know that the mechanical parts to the operator are very similar, could I switch the PA door board out for a PY or the FX2 board you are suggesting? What I am not sure of is that the PA operator has a VFD drive in it and runs a three phase AC motor. Are the PY or FX boards capable of running an AC motor? Or do I need to replace the motor with a DC motor? Vertical Express suggested installing an HD85 operator instead. I suppose I am wondering if I should just re-install the old operator, return the HD/LM operator and purchase the HD85 instead. This is the price I pay for not verifying the proper job number on the survey.
