Laserwash 4000 Dryer Time Issue

I've been having an issue recently where our stand alone dryer in one of our bays shuts off early. I have both bays set to 63 seconds. This bay sometimes shuts off with approximately 45 seconds (not always) left so they are only getting around 15 seconds or so of drying time which isn't enough. I cannot say if it only happens during certain times of the day. In the morning we have bright sunlight on the exit end of the bays. Do not know if the exit eyes getting hit by sunlight can cause an issue so I turned the amplifier down for those. No help. I then put some PVC over the ends to help shade the sun and it still happens. As far as I know there no in-bay sensors that have anything to do with when the dryer shuts off. Anybody have any ideas?
 
When I had dryer timing issues, I was told to check the bay length. My dryers wouldn't shut off. The opposite issue you are having. My bay setting should have been short, but was set to long. That fixed my issue.

Do you have the Carlo Gavazzi eyes and amps for your dryer sensors? Maybe the eyes are going bad. Check the amp as well, make sure it is working properly. Swap it with an amp that you know works. Just thinking out loud. These are things I'd check.
 
check the base also where the amp and the amp setting goes they go bad also and alignment of the eyes make sure a kid ain't pulled on them and throwed them out of alignment. Most of the time it's the receiver eye that goes first just from my experience.
 
I have checked the amp and settings and tested that the eyes are seeing the break at all points between the exit door eyes. Still no luck. I am also having no issues with the exit door closing after a customer exits the wash so that tells me that the eyes are working properly.
 
I don't know without being there. Have you checked the contactors in the dryer itself. I have replaced several of those. Maybe it's not holding in the entire time and something is making it so that. Have you checked the amp draw on the motors at the contactors while there running. Please be careful. Just something to try. This is a PDQ dryer right not a superior or something else.

Just thought about something if you go into parameters in the outputs section make the dryers come on to see if it holds in the contactors for like 2 mins and that's will eliminate bad contactors to make sure there holding more than 45seconds like you said.

I assume the dryer time cycle is not controlled by a Dixmor? I've had issues with the slave timer resetting to zero for no reason, had to send it for repair.

MEP001 is right make sure the PDQ control panel in paremeters and the diximor are both set to 60 seconds or whatever you like I have had a issue like that before once. They both where not Set the same
 
By Dixmor are you referring to the actual countdown timer displayed to the customer? If so I did not know that this actually controlled the dryer. I just assumed since the dryer time was set within the J0 that it was controlled by it. I thought it just sent a pulse to the display to tell it to start counting down. Tomorrow I will swap the two countdown displays to see if the problem follows.
 
I don't know if it controls it or not, but if it's on all the time and going out with the dryer on it probably does control it. Should be easy enough to tell, just look and see if there's a wire attached to the timed output. I've only used them as a slave so there wouldn't be a wire there.
 
Mine was doing the same timer set for 60 sec worked for a while messed with machine and then dryers starting kicking off at about 30 sec. Called pdq and got some sort of reset code and dryers went back to running for full 60 seconds>>>???
