How do you replace the PET sensor?
[added 5/12/14]

1. It's easier if loosen the front feed retaining screw with a flat screwdriver and gently pull the unit forward about Six inches.

2. Remove the plastic nuts holding the existing yellow sensors in the mount brackets. Unplug the connectors and remove the yellow sensors.  You may have to cut a few ties.

3. Install the new sensors. The Emitter will go on the right side and use the adapter harness supplied. Route the cable around through the front cutouts and to the left side to plug in. Tie up the cable with the cable ties. The Receiver will mount to the left side bracket , tie up the excess cable and plug in.  If the sensors plastic nuts are hard to reach, you can use the Phillips screwdriver to remove the two screws holding the bracket, remove/ replace the sensor,  then reinstall brackets. You can also use the pliers to remove the nut if needed, but only hand tighten securely when reinstalling or you may break the nut.

4. Make sure the sensors are fairly aligned across from each other. To calibrate, press and hold the top raised button on the left sensor for 2 seconds then release. (same procedure as the blue exit sensor.

For GUI LCDs, how do you not show the counter count on the LCD?
[added 10/11/13] Changed the line 197 of the message table line which is normally "%t" and change it to blank (don't delete the line!)

Glass bottles/paper cups/other objects are in the bins.
[added 6/26/12] Customer is either inserting the object and a can/PET bottle together or leaving the object inside from previous customer and inserting a can. If customer inserts a glass bottle, machine will tell you to remove it. If you open and close the customer door without removing the glass bottle, the machine has no idea the bottle is still inside the machine as we donít have a sensor near the  customer door or middle of feed area. The only sensor that can see glass is the sensor in front of the diverter.

The machine fails for "Exit sensor failed to clear" after the first container.
[added 4/27/12] Run diagnostic #1, 75 to see if the exit sensor indicates blocked with no container present. If so, recalibrate the sensor by holding the button on top of the blue exit sensor for a few seconds. This can happen if containers are jammed in the machine blocking the exit sensor for a long time, the sensor automatically recalibrates itself.

Cans try to be accepted but are left at the end of the conveyor just before the diverter and the RVM goes out of service for a diverter failure.
[added 3/22/12] The diverter behind the front conveyors may not be stopping in the correct position, the diverter sensors may be mis-aligned, or you are not detecting alum or steel.

1. Use Diagnostic #1, 61 to move the diverter to the down position. This is the position where the can should transfer off the front belts and slightly drop down 6-10 mm onto the diverter flap.
If the diverter has somehow moved upwards on the shaft it may be higher and create a wall that the can hits. The sensor will then see the can has not moved onto the conveyor and be rejected.
If this is the case, first turn off the machine for safety, then open the side door. You will be able to access the diverter flap and sensors from here.
If it is just slightly loose, you can usually push the diverter back to the correct down position with your hand. You will most likely have to hold the diverter shaft(hold one of the sensor target brackets
while pushing) to prevent the motor from just turning. If it is extremely loose(I suspect it may not be) and will not stay in place, you may have to retighten the set screws in the connecting coupler, holding the diverter to the main shaft. These set screws are in the coupler, under the sensor target brackets. Allen wrenches are required for this.

2. Possibly one of the diverter sensors is misaligned, You can use diagnostic #1, 62 to see if the sensor is stopped in the correct position. If not bring the targets in no farther than 3mm from the position sensors.

Small PET bottles aren't accepted.
[added 2/20/12] Top-heavy PET bottles tilt forwards and will not block the sensor in front of the diverter. The RVM rejects because it thinks someone is trying to cheat the machine. Workaround: insert container bottle-first. We're working on a solution involving moving the sensor forwards a bit.

Cans where the barcode couldn't be read are left at the back of the feed unit instead of the front.
[added 11/16/10] WinRVM automatically sends the option file supplemental.opt to the RVM when sending barcodes and "Enable supplemental barcodes in RVM when sending barcodes" is enabled in WinRVM's barcode options. The original supplemental.opt set USE_LASER=3 which causes this problem.
To fix, set the LCM's USE_LASER parameter to 5 by sending LCRVM.OPT. Copy the updated supplemental.opt to the CF1500 folder, overwriting your old version to avoid this problem in the future.

The RVM indicates the cabinet door is open when it isn't / Shaking the RVM activates the door open state.
Make sure the machine is level, adjust the leveling feet on the bottom of the cabinet to achieve this.
If still does not fix the problem, the machine has two safety magnetic switches on the doors. One on the bottom right of the upper door, and one on the top right of the lower door. They each match up with a corresponding magnet on the cabinet. You can adjust each magnet to mate it up with the other, the magnet holes are slotted.
The magnets should be almost touching, within 20 mm should be ok. The up and down alignment should be close also, as if they are too far off center this will cause problems. If you put the magnets on the cabinet side to test and it comes in service, this will tell you they need alignment. (if you do not have any magnets, you can temporarily remove the ones from the door and use these to test.
Make sure the 2 pin harness is connected to the top of the ac box. The two door sensors run parallel into this connector. The signal is then carried up to the RVM controller through the larger 15 pin connector from the ac box to the rear of the RVM controller. You can check these connections also.
You can place magnets on each magnet mounted on the cabinet. If it comes into service, the harnessing is good and you are not getting contact from one of the door magnets when it is closed.
Make sure the silver key is not in the ac box and turned to the up position. This will also cause the machine to not come into service.

While the RVM is Processing, the door does not lock.
This issue may also be solved with the leveling of the cabinet as the customer door sits inside the front door opening and if it is not level could through off the door latches.
Enter diagnostics and use #1,77 to test the door latches with the customer door closed. The latch bracket assembly can be adjusted by loosening the two front Philip screws to align the locking tabs into the latch holes.
The door latch bracket may either be loose or may need to be bent slightly inwards to tighten the gap between the switches. Look also at the switch brackets mounted to the cabinet just to make sure they are not loose or have somehow bent outwards.

If the problem happens intermittently, the locking pin may be magnetically bound, preventing it from dropping. Use diagnostic #1,77 to lock the door then use your finger to pull up on the door latch:

If the latch remains in the up position (unlocked), there is a problem. Make sure a washer is installed on the door lock solenoid:

If a washer is present, try adding a second washer or thicker washer.

Loyalty Card Reader only showing partial pattern.
If the scan pattern from the loyalty reader only shows ĺ of the pattern, try the following fixes:
a) Leveling the machine with the 4 leveling feet will usually put the main door in the proper position for the scan pattern to fully appear.
b) Adjust the scanner bracket to allow the pattern to fully appear.

Machines, Screens, and AC units not powering up
Check if the power plugs have vibrated loose. Anytime the machines are transported, upon arrival all connectors should be checked for seating. Heavy vibration and rough international transit could cause connections to vibrate loose, and this was found to be the cause of the above power issues.

Customer door not lining up.
Each time the machine is moved to a different location the machine must be leveled with the 4 leveling feet located below each machine leg. It is imperative that the machine be leveled and on solid ground. Once the machine is leveled each in-feed module must be adjusted correctly to assure proper customer door and push button operation.

Diverters getting stuck and taking machine out of service.
Occasionally this will happen and the adjustment is part of the routine maintenance. Over time from continuous movement and vibration occasionally the diverter arms will need to be adjusted.
