The RVM Monitor ROM logs an "Error 999: Watchdog reset".
[updated 7/16/09] Remove the "watchdog enable" jumper (labeled WDEN, near the battery) from the RVM controller board.

The RVM fails for "out of coins" and then "coin power relay stuck on", but a printer is installed, not coin hoppers.
Set the following parameters to 0: COIN_HOP_TYPE, LEFT_HOPPER, RIGHT_HOPPER.
CF1500 SC: edit PARMS.TBL and run SCSETUP, then the SC.
MU2000 SC: edit edit PAnnnnnn.TBL (where nnnnnn=RVM serial #), then run the SC.

On power-up, the RVM beeps 3 times quickly, delays 2 seconds, then repeats.
The processor self-test is failing. This is a serious error that can be caused by many things such as a short circuit on the controller board, a defective CPU, defective memory, or any defective electronic component. The RVM controller board should be swapped out and the old unit sent in for repair.

On power-up, the RVM beeps twice quickly, delays 2 seconds, then repeats. The RVM software never runs (stuck in MON1500).
The LCD/VFD is not being detected. Make sure it is plugged in. Swap with a known good display.

The RVM software doesn’t run.
When you turn on the RVM controller:
1. Does the red light by the power switch and the fan come on?

If not, check the wall outlet for power, check for blown fuses.

2. Does the cursor show up on the display, but no text? Make sure the LCD is plugged in and getting power.

3. Does the display show "MON ..."?

If the RVM does not make it this far, the RVM controller board is bad and must be replaced.

The LCD displays "MON 1500" and beeps (every 8 seconds if in RS-232 mode). 
Note: this is normal behavior for a new RVM controller that has never been used.
The RVM memory has been trashed somehow. Check that the battery jumper (W3) is installed snugly. Reload the RVM software by selecting "Install RVM program/Create Machine" from the PCRVM main menu, or alt-L if a site controller is attached. Once the RVM software is loaded, check/set the serial number via keypad command #9, 04. Check the battery voltage via keypad command #1, 25. If less than 2.9V, replace battery.

Unable to enter PIN

  • Open the cabinet door and press any key, the RVM should display "ENTER PIN:____", and display a "*" for each key press. If not, the keypad may be bad. Swap the keypad for a good one. Reloading the software may also fix this problem under certain circumstances. 

  • If the LCD displays a "*" for each key press, but the RVM beeps after entering all 4 digits of the PIN, then this indicates the file PINS.TBL is either incorrect or not loaded. Check the PINS.TBL file to make sure it contains the proper PINs in the proper format. Send PINS.TBL to the RVM (if using a SC, just edit and save the file, then reboot the PC).

The RVM is out of service for "Waiting for startup" and the site controller displays "operation suspended".
Reboot the RVM and the site controller. Check all communications cables. Force-load the RVM via alt-L. You may need to reset the RVM’s serial number via keypad function #9,04.

A communications failure occurs after loading approx. 2000 bytes of the RVM program to the RVM.
The LCD is either unplugged or defective.

RVM won’t take steel cans with an aluminum lid.
Typically, RVM software is set up to reject steel cans that are less than 90% steel. Some cans such as 1 Liter Danish cans can be as low as 82% steel, 18% aluminum. To fix this problem the RVM parameter STEEL_RATIO must be lowered (for this example, a number less than 82%). To determine the actual steel ratio, run the CONSOLE or CONS485 program, enter "VIEWAD:ON" and then run the can to view the data. Enter "VIEWAD:OFF" when done.
Note: certain RVM versions after 7/23/99 don't support the "VIEWAD" commands, you will know if the RVM responds with "ALERT_:150".

How do you enable/change the barcode-on-a-voucher feature?
[updated 4/12/17]
See also: Cash voucher Barcode specifications  

CF1500/U48:  

The easy way: use the VoucherMaker program (for text printers or Hecon C56 printers), or the Coupon Designer program (for Hecon X56, Hecon C56, Swecoin printers) edit an existing voucher file that was created for another store. See the barcode section of the Coupon Designer documentation for the actual codes to use.

By hand:
If the current voucher does not have a barcode on it:

If this is a SC installation: save a copy of the original voucher in case you ever want to revert back to it by copying CASH.VOU to CASHOLD.VOU. Copy CASHUPC.VOU (or CASHEAN.VOU for EAN) to CASH.VOU. The cash voucher will now have a barcode of 000000 (which replaces "Thank you for using an Envipco recycling machine to help keep our environment clean" message. To change the barcode, proceed to the next step.

To change the barcode on the voucher:

For a UPC barcode (normal):

Edit CASH.VOU (if SC) or CASHUPC.VOU (if PCRVM), 
change the 6 digits after "57" that are 0s on the line: <B4B11A57000000%D%$n
to the desired digits for the first 6 digits of the barcode. The above example uses a "price check digit" or "random weight" as the 7th digit as indicated by "%D". If the store requires a fixed value instead for the 7th digit in the barcode, change the "%D" to a single digit, like 0. 

Note: Cybertech 9250 graphics printers use a different command for the barcode: <B4B2A150000000%D%$n
Change the last 6 zeros in the above line to the desired digits for the first 6 digits of the barcode.

SC: The modified voucher file (cash.vou) will automatically be sent to the RVM the next time the SC is run.

PCRVM: hold down the shift key when selecting "load voucher description files" from the "Load table to RVM" menu, then select the filename CASHUPC.VOU.

For an EAN barcode (infrequently used):

The Cybertech text printer software must be at least version 3.0.9 (released 3/98) to support printing of EAN barcodes. To determine the printer software version, remove the two screws on top of the LCD cover, remove the LCD cover, push the "test" button on the upper-right of the printer board. A ticket will print that indicates the software version.

Edit CASH.VOU (if SC) or CASHEAN.VOU (if PCRVM), 
change the 8 digits after "57" that are 0s on the line: <B6B11A5700000000%$n
to the desired digits for the first 8 digits of the barcode. The above example doesn't use a "price check digit".

Note: Cybertech 9250 graphics printers use a different command for the barcode: <B6B2A15000000000%$n
Change the last 8 zeros in the above line to the desired digits for the first 8 digits of the barcode.

SC: The modified voucher file (cash.vou) will automatically be sent to the RVM the next time the SC is run.

PCRVM: hold down the shift key when selecting "load voucher description files" from the "Load table to RVM" menu, then select the filename CASHEAN.VOU.

MU2000:  

Edit the end of the last line of CASH_UPC.VOU which ends in "<FC;123456%D%$n". Change 123456 to the desired 6-digit barcode, rename the file to CASH.VOU. 
On-site: Reboot the PC and the modified voucher file will automatically be sent to the RVMs.  

Remotely: Make the above changes to CASH.VOU and send the this file to the site via the takecall system.

200-series:  
Apply an option file such as barcode.opt which contains:

*THIS OPTION FILE ENABLES THE BARCODE ON-A-VOUCHER FEATURE
*ON 200-SERIES RVMS BARCODE OF 2887590
:2151 28
:2152 87
:2153 59
:2154 30

Note: Syntest printers do not support UPC or EAN barcodes, they only support "3 of 9". A Cybertech printer must be used.

MU1000 glass/PET RVMs: set the PAYMENT_BARCODE and PAYBAR_CKDIGIT parameters in M_PARMS.DO (requires MG16 or MP16 or later software). See comments in M_PARMS.DO for details.

MU1000 can RVM: 
Set BARCODE_PRN1 and BARCODE_PRN2 parameters in CANPARMS.TBL (requires 10/27/93 or later can RVM software). See comments in CANPARMS.TBL for details.

How do you remove the barcode from the cash voucher?
For Cybertech printers: edit CASH.VOU, delete the line that contains "B4B11A57...". Replace with the following text to make the ticket length the same:
"Thank you for using an ENVIPCO recycling machine to help keep our environment clean."

The store’s scanners can’t read the barcode on the cash voucher.
Verify the first 6 digits on the barcode match what the store is expecting. The 7th digit can either be a fixed number, or typically, is a "price check digit"/"floating check digit"/"double-active check digit", which means that the 7th digit varies, depending on the amount. The RVM software may be configured to print the 7th digit in the wrong format. See Cash voucher Barcode specifications for more info. 

For CF1500 RVMs, if a "price check digit" is desired, but the RVM is printing a fixed 7th digit: edit CASH.VOU, change the last digit ‘x’ in the line "B4B11A57nnnnnnx%$n" to "%D".

How do you determine what the last barcode that was read by the RVM? Run the CONSOLE or CONS485 program. Type "REQUST:UPC". The RVM will display the last barcode it read. A musical note character indicates that no barcode was read. Six-digit barcodes will be displayed with 4 trailing "F"s.

Coins won’t vend from hopper, even though hopper is full of coins.
There may be a quarter in the nickel hopper or a nickel in the quarter hopper.

How do you configure a machine to accept steel?
Change the RVM’s REJECT_TYPES parameter, silo table, and add steel barcodes with the correct material type byte.

The RVM accepts containers, but won’t pay for them.
Make sure the DEPOSIT parameters are set correctly (DEPOSIT0 typically set to 0500) and the corresponding barcode table entry indicates the correct deposit amount. If taking unreadables (TAKE_UNREAD), is the machine configured to pay for unreadables (UNREAD_VALUE),?

The cash voucher doesn’t print the site name or number.
Reboot the Site Controller - this should resend the info; print a voucher from diagnostic #1, 45 to verify. Check the file SC_CTRL.PRM for the correct info on the SITENAME and SITEID lines. Check the cash voucher template (CASH.VOU) for the proper format.

The machine is in "sleep mode", how do I wake it up?
Use keypad function #9, 06 for MU1000 RVMs, #9, 07 for MU2000/CF1500 RVMs.

CE1992 can machines should never enter sleep mode, but if one does, it indicates a module memory error. They only way to recover from this problem is to reinitialize the module with PCMOD. The module may be defective.

A particular barcode doesn’t scan, is there a way to tweak the scanner so that it will scan this barcode?
No. All you can do is make sure that the scanner’s glass window is clean for best performance.

The RVM’s crusher/shredder stalls every time.
Make sure the RPM sensor is plugged in.
Check the "SH_STALL_TIME" parameter for the proper value.
