HEALTH” HEALTH SETTING ROUTINE
This function is used to enable the health protection feature for product when needed. When enabled it operates
as follows:
1. Cabinet temperature must be maintained at 41 degrees F (5 degrees C) or below for product to be
vended while in normal operation. If the cabinet temperature exceeds 41 degrees F, and fails to return to
41 degrees F or below for 15 minutes the controller will issue a “HCOD” error and disable vending of
health protected products.
2. After door closure, (refill or service) the machine has 30 minutes to pull down to 45 degrees F (7 degrees
C). If the machine has not reached 45 degrees F (7 degrees C) after 30 minutes the controller will issue
a “HTIN” error. Once a health time error is activated the controller will not allow product to be delivered.
After 30 minutes if the temperature is 45 degrees F or less, but not 41 degrees F the controller will set a
15 minute timer. During this time, if the cabinet temperature falls below 41 degrees F (5 degrees C) the
controller will allow health guarded product to be delivered. If the temperature doesn’t fall below 41
degrees F (5 degrees C) the controller will issue a “HCOD” error and disable vending of health protected
products.
3. Power loss for 30 minutes or longer will result in automatic “HCOD” error activation and disable vending
of health protected products upon power up.
4. Power loss less than 30 minutes. Once the machine regains power, if the cabinet temperature is 45
degrees F (7 degrees C) or less the controller will allow product to be dispensed. The controller will allow
an additional 15 minutes for the temperature to pull down to 41 degrees F (5 degrees C). If the
temperature doesn’t reach 41 degrees F (5 degrees C) or less after the 15 minute period the controller
will issue a “HCOD” error and disable vending of health protected products. If the temperature is greater
than 45 degrees F (7 degrees C) on power up the controller will automatically set a “HCOD” error and
disable vending of health protected products.
5. Power loss less than 15 minutes. On power up the controller will allow vending. If the cabinet
temperature doesn’t reach 41 degrees F (5 degrees C) or less in 15 minutes the controller will issue a
“HCOD” error and disable vending of health protected products.
