No worries jluff just trying to establish what is happening . Haven't worked on a true MRL Gen 2 in ten years ( that was the only type of Gen 2 in the u.k where you don't need. Controller space ) . All of mine here have the controller exterior . With that type of controller the gov trip / reset button is a silver button on the maintenance panel above the moveable circuit jumper on the right hand side side ( above controller inspection controls ) it only functions if you go in to safety test functions ( m-2-2-5-1 on service tool ) and scroll through until you come to Gov trip or gov reset . You enable one or the other and then the button should work ( or quite often not as the solenoids in the governor tend to pack up ) . The buttons on the board are UCM reset button and CpU reset button . I don't know the setup in the door jamb with the controller in the hoistway tho to be honest so it could be the Gov trip/reset you are hitting . The fault lists you should look at are the OCSS event list ( M-1-2 ) the MCSS event list (M-2-2-2 ) ( this is the most important one ) and the DBSS ( M-4 ) . With the drive there are two fault logs one gives you a history in a format that looks like this
F58 R20 F56 R45. Etc ....
The f number is a fault code and the R number is the amount of times it ran between the faults . To clear the ocss and mcss fault logs go into the log to view the faults and hit blue 5 blue enter . To clear the drive faults is an option at DBSS menu.
Next time you get the fault make a note of all the info in the above event lists and then clear them all . Let us know what they say . Hope this helps .
