Received a call that elevator was shut down. On arrival the pwr. was turned off. Inspected elevator for anything physical wrong, did not see any problems. Placed car on independent service to turn power on. Returned to run car and it runs fine, every floor, doors open and close fine. Placed the car on automatic to check how that's working and also work fine. Every car call operates as supposed to. Then I decided to check hall calls and (three car group)could not get the same car to respond to a hall call at least at the floor I was at. sent the other cars away. However, the car would answer some call at another floor open and close door. It would answer calls at any other floor except the floor it is parked on but not all the time just intermittently. Tried to use the computer in the Mach. Rm to check for faults or anything that would point to something. I had no success the program would not run. The car also has a longer door time at the second floor after it arrives. Then closes the doors and waits for another hall call at a different floor. Any Ideas, first time working on a miprom controller. Not a lot of information available in the mach. rm, any thing would help and be appreciated.
