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.

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.
