Citizen L20 Initial Start up

Not familiar with Citizen at all. Acquired two machines and have just hooked them up to power. Bar feeders are not connected yet.
Turned on the power and getting alarms on both. Wanted to jog the axis around and get some lubrication going. Not sure how to clear the alarms.
Do you zero return these machines at start up? Both are 1997 machines with windows based software.
Thanks

You do not need to zero return them, If you turned them on with any doors open or anything, and you may have to have a bar feeder hooked up too, it will throw all kinds of alarms.

Does anyone know where must to be located this paper io sensor?
