Hi All, arrived onsite to ohs relay chattering and getting 86vac instead of 120vac. At first doors still operated in open then they quit altogether for open. Door close circuit seems alright. Replaced module that fed the ohs coil and now have 120vac and no chatter there but still doors do not open. OHS changes state and OD contactor pulls in the prints i have onsite don't seem to show the ohs relay. Thanks all.
