Telco Magic Box problem


I had my first paying customers that I have seen today but the only problem was the Water Wizard did not work right.  The gantry boom would not go down during the wash and the wash would stop before the triple foam function.


About the problem:  The Telco PA11B303T “magic box” works with the transmitting and receiving safety eyes located on the gantry and the cans on the front of the gantry.  When the gantry safety eyes do not read a car the unit will not drop the boom, which was my problem.  But the real problem was my Telco magic box when I switched the boxes the signal indicators were not lit and would follow the box.  So I am going to over night a new magic box to get my automatic to work again.

Proximity sensors problems again already?


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?


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.

Water Wizard Preparation – Gantry test


I labeled the “box of power” today, actually it has only 3 things and the electrician told me the answers.  William and I turned the power on and moved the gantry for the first time today and there was a problem.  The third picture shows how the gantry gearbox bolts hits the rail bolts.  So William cut off all the bolts then the gantry can move back and forth.

Water Wizard Preparation – Rail heat install


William installed the rail heat today along with the home and away things (second and third picture) for the automatic.  The rail heat is installed inside the rail and is a copper line.  The home and away things make sure the gantry does not go to the end of the rail and shut down.

Water Wizard transfer day


We rented a Penske 24 foot truck, blue dual axel trailer, and fork lift today to move the Water Wizard.


William just put the gantry on the trailer and strapped it down with 4 2″ tie downs, which we purchased from Lowes.


The pumping station went into the back of the truck along with the rails, entry gate, etc.


It was a long and bumpy road and my back is going to hurt tomorrow.  “Air Ride”… I say back breaker.


William moved the gantry off the trailer without any problem!


Thanks again William and my Dad for your help today.
