OUT OF SERVICE MESSAGE

Certain critical errors will disable the Fresh Healthy Vending Machine. When this happens, an “OUT OF SERVICE” message will be displayed. If the error is related to the Health and Safety function of a perishable food Fresh Healthy Vending Machine, the “OUT OF SERVICE” message will be followed by an error code beginning with “HS.” Refer to the section on Health and Safety errors below. Please note that if a Health and Safety error occurs, any food which may have spoiled should be discarded.

To get the Fresh Healthy Vending Machine back in service, press the mode switch on the control board. Any errors will be displayed immediately. Refer to the list of error codes and explanations below. Correct the cause of the error first, then press “0” to clear the error code. Certain errors will have more detail available: press 1 to see more detailed (sublevel) error codes, or 2 for date/time of last occurance.

HEALTH AND SAFETY ERRORS

NAMA specifications for perishable food Fresh Healthy Vending Machines require that the temperature in the Fresh Healthy Vending Machine must cool to 41°F within 30 minutes of closing the door (note that Delayed Sales has no effect on this 30 minute cool-down period). This is to allow a recovery period following loading- however, all products should be chilled prior to loading. After this requirement has been met, the temperature in the Fresh Healthy Vending Machine must never get above 41°F for more than 15 minutes.

For Fresh Healthy Vending Machines having this software, the H&S function is activated automatically when the temperature is set to 41°F or below. Unless otherwise specified by regulatory agencies, Fresh Healthy Vending recommends setting the temperature to 40°F when vending perishable food products.

In the event the internal temperature exceeds the NAMA specifications following the recovery period or during normal operation, an error will be generated
and the Fresh Healthy Vending Machine will not allow further sales. This protects the consumer from purchasing spoiled food.

The H&S function can be tested by manually warming the temperature sensor to simulate the failure conditions.

MACHINE ERROR CODES: CAUSES AND SOLUTIONS

Viewing Top Level Error Codes: To view top level error codes, enter the service mode by pressing the mode switch located at the lower right corner of the control board. ACCT DATA will be displayed if there are no errors or an error has been cleared (whether corrected or not). If the error message has been cleared, but the cause has not been corrected, the message can be re-displayed by briefly turning off the power. Use the keypad buttons to perform the following:

#. NEXT ERROR – to view the next top level error code in memory.
2. DETAILS – displays the time and date of last error occurance.
1. SUBLVL ERRORS – to display any sublevel error codes including MDB devices.
0. CLEAR ERROR – to erase the error code from memory (first correct the error).

Viewing Sub-Level Error Codes: To view the sub-level error codes, press the 1 key while the top level error code is being displayed (Refer to 7.3.3). Correct the condition which caused the error first, then clear the error code by pressing “0”.

Once all errors are cleared, “ACCT-DATA” will be displayed.

CLEARING JAMMED MOTOR

If one or more motors and helices become jammed, the motor(s) will be displayed as a sublevel error under “Motor Jammed”.

Energized vend motors can turn a helix with considerable torque, creating a possible entrapment hazard. Disconnect power to the Fresh Healthy Vending Machine or control board before freeing a jammed helix or motor. Always restrain or block the helix before freeing a jammed or caught product.

CAUTION: Use caution when freeing jammed product (Refer to 2.2.4)!

Clear any jammed products from the indicated vend columns.

To reset the error, first enter service mode, then select Tray Setup. Press “1”, then “ * “, then “3”. The control will attempt to run the jammed motors. If the motor had been taken out of the motor matrix, it will be re-established in the matrix.

WATER FORMATION IN THE CABINET

Water formation in the cabinet indicates an air leak which allows moist air to continually enter the cabinet and condense on the evaporator.

  1. Make sure the refrigeration unit cover gasket is sealing properly all the way around. In particular, check the openings where the refrigeration lines and drain tube pass through the cover. These openings should be sealed completely around the lines and tube with duct putty.
  2. Make sure the door is properly tightened so that it makes contact with the gasket on all sides.
  3. Make sure there are no foreign objects interfering with the vend door, and the vend door closes properly.
