Problem with the undercarriage

IMG_9483.JPGIMG_9495.JPGIMG_9494.JPGIMG_9496.JPG

I am having a problem with my undercarriage staying on for only 6 seconds when it should stay on for 30 seconds.  So the culprits are the entry banner eyes, what is weird is the eyes are giving 2 pulses when the eyes are blocked once.  I swapped the eyes with the front treadle eyes and the undercarriage worked perfectly.

The Water Wizard uses the same Banner eyes for the front (treadle) and the back (entry, undercarriage).  These eyes are in pairs with one receiver and a super duper laser emitter.  The Banner emitter is the SM306EQ and the receiver is the SM30SN6RQ.

Proximity sensors problems again already?

IMG_9434.JPG

William replaced the “home” prox today.  The gantry was passing the “home prox target” (which is under the prox) and hitting the end of the rail.  So this is an easy prox to troubleshoot because the unit will just stop and be at the end of the track.  While William was installing the sensor he did have to adjust it to make it closer to the target because the gantry would miss the target and hit the end of the rail.  While reading the specs on the inductive sensor you have only 15mm sensing range, so this was our problem.

Again:  The Jim Coleman model number is 6626 and the Turck model number is Ni15U-EM18WD-AN6X-H1141 id number is M1634835 .  If you want to look at all the Water Wizard parts for some reason check out this.

Proximity sensors problems already?

IMG_9433.JPGIMG_9435.JPG

William replaced the gantry “end of track” proximity sensor along with the “lower boom prox”.  The “end of track” prox tells the machine that the unit has traveled to the end of the track.  If this prox is bad you will know because the gantry will not move but still run though a wash normally.    The second prox replaced tells the “wash boom” when to stop the boom so it will not hit the end of its track.  If this prox is bad the boom will be lower then normal and probably be pressure washing the ground.  Both the sensors are located on the passenger side of the gantry.

This type proximity sensor used above is used in many locations in the Water Wizard.  The Jim Coleman model number is 6626 and the Turck model number is Ni15U-EM18WD-AN6X-H1141 id number is M1634835 .  If you want to look at all the Water Wizard parts for some reason check out this.

Hamilton entry unit problem

IMG_9395.JPG

I called Hamilton support today (1-800-837-5561) and they dialed into my modem and checked out my credit card computer.  They said that the unit was turned off for a very long time and it was reset a lot of times.  So apparently they can not really check anything by dialing into the system.  (I knew that much!)  They did say to send the unit in to them and they think it will cost anywhere between $200 and $500 to fix.

Hamilton entry unit problem

IMG_9375.JPGIMG_9377.JPGIMG_9374.JPG

William was trying to show me how the entry unit works and the Hamilton handheld would not work.  (The handheld, from what I have gathered, programs prices and the credit card computer.)  William called Hamilton to try and get the handheld to work but nothing would work.  Ends up that the cord was messed up (last picture).

I took the $1900 Hamilton credit card computer home with me to fix the handheld cord, which I did.  I did not take the 2 boards apart but the top board looks like an Aprotek modem.

Water Wizard control unit problem

IMG_9337.JPGIMG_9338.JPGIMG_9339.JPG

We were having a problem already with the Wizard control unit not allowing us to test each function.  Ends up that the Red Lion (1st picture, has a display on it) was not plugged in.   The silver plug (2nd picture) was a little loose and that was the problem.  So our first problem was solved!
