IP1 Relay PCB, where is it??? | 4 December, 2006

I work for a small SMT contract manufacturer with a couple SMT lines utilizing both old (IP1, CP3) and newer (CP643, XP242)Fuji machines. We have an issue with an IP1 that has us stumped. One of the device locations has no power. After some basic troubleshooting, I feel I've narrowed the problem down to the "Relay PCB". The problem is, I can't find it!? The schematics show it located on the right side (facing the front). We have both the electrical and air drop bolted to this side of the machine. I've partially pulled the side panel off and can't see where the "Relay PCB" would reside. I would rather not have to pull off the power drops until I know for sure this will gain me access to the Relay PCB. Has anyone ever had to access this part of the machine before? The schematics are not specific as to EXACTLY where the board is and even Fuji was stumped when I called tech help. It seems this machine is too old, all the young teckies don't have any experience with it...

Todd,

It's been a while since I have looked at this but I believe the IP-1 does not have a relay board for the feeders. +24 Vdc is wired to a pin on the connector and the I/O board (NO 3 I think) switches the ground. If you don't have +24 Vdc at 1 feeder location it's probably a broken wire. These connectors come loose some times and rotate breaking wires on them. If the +24 Vdc is at the connector but it still does not work it's probably the I/O. Jerry

The "Relay PCB" is # CON I/F 8909-0. Of course it's a real old drawing with many of the P/Ns being obsolete. I'm looking at drawing # SIP-1750. The Relay PCB is shown between the 1st station connectors and the control box. In the meantime, I'll double check for my 24Vdc. This issue has been on the back burner for awhile and I'm just looking back into it. I don't remember a lot of what I looked at before...

I'm not finding 24Vdc at any feeder location?! I checked all pins with the coresponding feeder activated through the I/O and a key in the emergency disconnect. Am I not using the correct procedure to check for my 24V?

What year is your machine and what year is your Electric Drawing? My machine is 1989 and so is my drawing. I do not have a SIP-1750 drawing. The IP went through several changes during its production so your machine may not match mine.

The CON I/F 8900 board is used on the IP-II so maybe later IP-I's also got this. If so I don't know where it is but you can try to backtrack the cable from the feeder connections.

I can never remember which pin on the feeder connector is 24V so plug a feeder in and you can get the +SOL wire on the solenoid easy enough. You need to pick up GB as the negative. Usually easiest to pick it off of one of the sensors.

Do IP1's use MFU's like the IP2's ? If so I can most likely tell you what the problem is....

Please advise.

All of the IP-1's I have seen use a fixed feeder bank. No MFU's which is where the board is located for IP-II's.

Ok, an update... I finally found my 24Vdc. I was trying to use a screw and/or outside of the connector for ground. It was necessary to use the ground IN the connector pins. I believe it was the top/right and 3 o'clock pins that toggled with the 24Vdc. The faulty device location did not have 24V. I checked the wiring behind the connectors and it looks fine as far as I can tell. We finally found our "Relay PCB", but have yet to get in to look at it. We have recently had our parent company purchased by a very large leader in their industry and they have very strict safety procedures. We are awaiting an electrician to remove an electrical box that is mounted to the side panel we need to access. I have pulled the panel away enough to see a bit of the PCB, but not enough to get a good look. For those who are curious, the PCB is located behind the right/lower body panel (facing the front of the machine), just beside where the air regulator is mounted. And, for the record, the machine has a manufacture date of Aug. 1990. I want to thank all for your input and help. What a great forum for this type of thing! I will reply later once we get in to look at this "Relay PCB"
