Test the Health Control
Use this procedure on model 480 merchandisers configured for refrigerated food to verify
the operation of the Health Control Automatic Shutoff circuitry. The purpose of the Health
Shutoff Control is to disable the vending mechanism whenever the machine does not
maintain the air temperature in the food storage compartment at or below 41oF (5oC). The
temperature shutoff requirement does not apply for 30 minutes after filling, servicing or a
defrost cycle.
NOTES:
a. The Automatic Health Shutoff Control timer resets every time the cabinet door is
closed.
b. The internal cabinet temperature can be viewed on the credit display by pressing
.
1. Check the temperature of the food compartment by pressing to ensure that the
machine is not in the 30-minute recovery period that occurs after the door is closed
following filling, servicing or after a defrost cycle. If the machine is in the 30-minute
recovery period, the time remaining will appear on the display. Before proceeding, wait
until the recovery period ends.
2. Open the main door a minimum of 45 degrees to allow the food compartment
temperature sensor to warm. Observe the cabinet temperature on the credit display by
pressing the button. When the temperature on the display rises to 42o F (5.5oC),
the message " ", “ ” or “
” depending on machine configuration will display. This verifies that
the vending mechanism of the machine has been disabled as required. With the door
open, the sensor temperature will typically reach 42o F (5.5oC) in less than 5 minutes.
3. Press the but ton and the message "HCER" ( Health Control Error) will display.
This is the message a service person would observe after opening the door.
4. Close the main door. You may observe the recovery time and temperature by pressing
again.
