Help with a CSM 84 V | 15 April, 2007

Hi Brand new here and I really need some help on a problem with a Philips CSM84V. We have programs loaded and they worked fine awhile ago. When we hit run now, the conveyor starts running without the board being present (says "transporting pcb" not waiting for pcb), and the stops do not come up. In other words, instead of the stops coming up and waiting for the board to be put on the sensor, we place a board on the running conveyor and it will just shoot through the machine out the other end and onto the floor.

Is this a problem with a sensor somewhere or an obscure setting somewhere in the menu?

Your help is very much appreciated, thanks

Check Running Menu Run Mode 2 = Normal (Pass) Mount = Exec (Skip)

Data In > PCB > Origin > O* > Skip = No Data In > PCB > Mount > M* > Skip = No

Data In > System > Parameter > Position > Waiting Pnt Check that the waiting point is not set at such a co-ordinate that the PCB sensor is seeing the gantry. The pcb sensor also has a sensitivity adjustment - it may be turned up too high. I think your pcb sensor will be DI24 on the DI/DO page. Cable number should be N24. Put your hand over the sensor and DI24 should show the number 1. If you take your hand away it will show 0. If this is not the case, I.E. it stays on 1 - then your sensor is cactus. Swap the cable to either the conveyor input or output sensors to check. To keep running while you get a new sensor - If you have a sub-stopper that has a working sensor then move it to the pcb position, connect to N24 and turn the sub-stopper option off in Data In > System > Machine Config > Sub Stopper = No. If you do not have a sub stopper then move the Exit sensor to pcb position, plug in to N24 and set Data In > System > Machine Config > Conveyor Spec= Return. This will mean the pcb will return to the entry after the mount is finished. Grab it and put in a new pcb otherwise the same pcb will be populated again and again, while you're in the brascoe.

"we place a board on the running conveyor and it will just shoot through the machine out the other end and onto the floor." That's funny!

Yep you were right, turns out the middle sensor went bad. Thanks again for your help.
