HTK screen reads out of service. Inside HTK the WIS (wash in service) light is not lit. Hamilton tells me it's not receiving a signal from the wash. OK. The input and output board are lit as they should be. No code on the two digit in bay display. Any suggestions? I'll add a secondary...

And now the thing is working again. I left the power off for 2 days b/c I couldn't get to it due to employee absence at another business. Went today to pull the PLC and the contactor didn't close when I switched the breaker to turn on the 110 on. Operated it manually with no problem. Ran...

Ok. So, this is all coming together. Before this issue, I was having having an issue with the Q13 breaker tripping. Found a severely corroded solenoid under a water leak. Switched it out and the breaker issue was resolved. However, this was when the issue with the gantry contactor began...

Got it thanks.

I had that thought last night. Perhaps the water cooling feature is shorted on and is causing the constant signal. So, how do I go around the water cooling feature? THere is only one wire on Y13. Where should I be looking?

Yeah, the replacement seems pretty straightforward with the caveat that the terminal strip comes off. I’m more worried that I’ll have to get Ryko out to program it. Think I may be able to save some coin and headache by sending it out for repair. I also have a soft gloss, which gets most of the...

Where did you get the PLC, price of, and who installed? If you don't mind. I just listed my car wash for sale. So, I'm not really game for a big repair. I think i'm leaning toward pulling the plc off and sending out to a control company for repair.

My man. Thanks for this info. Had a dead battery on my meter so had to remove wires. Yes removing the 24v wire from the bottom of the the contactor opened it. Connected that back and then removed wire from the y13 terminal. That also opened contactor. Obviously there is constant charge on...

Yeah. I've shut down all power. Actually left it off overnight. I haven't had a chance to go back today. Is the gantry contactor supposed to be closed? I'm digging through books now trying to find the info for relays. I've been pretty lucky with the OHD thru the years. This has really...

I'm lost. My go to tech says he's never heard of such. So show me your skills ryko pros, please. The trolley and the gantry move at the same time. If I manually drive the trolley to the left the gantry moves in reverse. If I manually move the trolley to the right the gantry moves forward...
