Ted,
BEWARE that if the cabin or car call button is disabled, the elevator must still function on phase one and phase two operation.
I would strongly recommend the video published by NAESAI.

An extra waffer on the fire service phase 2 switch inside the car might be the key.
Respectfully Submitted,
