Heidelberg MOVP electrical problems

trying to pinpoint my problem, when u start feeding paper into the press it engauges the first unit then it does not engage any other unit when all units are selected. i am having to push the breaker switches in the electrical box for impression on the last three units. Please Help!!!!!

 

Might be from the photocell of second unit
What model do you have?

 

MVOP = 4/c perfecter stream feeder

 

ftwaltonprint - There are no photocells on MO presses - your issue, given the press does not have CPTronics, is more than likely at the roller switch on the 1st or 2nd printing unit impression cylinder as I mentioned in my post to you on Heidelberg Repair Forums.

 

ftwalton - My apologies for not being clear, the infeed obviously has photocells, which appear to be working fine as the first unit is reacting as it should, unlike Speedmaster, there are no impression sequencing photcells between units.
