HEALTH SAFETY FIELD TEST
0.7.4 HEALTH SAFETY TEST
The HEALTH SAFETY feature prevents the sale of perishable food if the air temperature
inside the Satellite Food Vendor compartment rises above the Health Safety temperature
limit for more than 15 minutes. The factory default for health safety limit is automatically set
when the refrigeration configuration is set. The perishable products being vended must
match the refrigeration configuration.
Important Note: Make sure that the Health Safety setting is enabled prior to starting this
test. See Service Mode 4.9.1 below.
1. Close the door and wait 75 minutes for the temperature stabilize
2. Simulate Warm Temperature
a. Open the door
b. Locate the sensor at the back of the cabinet above the top tray.
c. Remove the mounting screw; place the sensor in a cup of warm water.
d. Enable HS Test software setting in control board service mode. See below
e. Close the door.
3. Perform Test
a. Press
on the host machine numerical keypad to check the temperature.
b. Wait until the temperature is above the upper health safety limit of 41ºF for
15 minutes.
c. Try to vend a product from the Satellite Food Vendor.
d. If the health safety is working properly the vend should fail; the machine
should have automatically been disabled by the controller board.
4. After Test is Completed
a. Open the Satellite Food Vendor door
b. Remove the sensor from the cup of water and put the sensor back in place.
c. Close the door and time how long it takes for the Satellite Food Vendor to
get below the refrigeration set point. . Cold should be below the set point
within 30 minutes.
When HS test ON (HS Door switch override ON) is saved in Service mode, and the
machine door is closed the Health Safety Activation Delay Time is set to the 15 minute
value rather than the extended 30 minutes for Cold and 75 minutes for Frozen that is
allowed after a normal door closure. To allow for multiple door open/closes and door close
debounce the HS test mode is active for 3 minutes after "HS test ON" is set in Service
Mode, so that if the door is opened/closed multiple times the 15 minute timer would be set
again and still be used. Also, when "HS test ON" is set the refrigeration OFF timer should
also be reset at this time so that when it is time for the minimum off time to expire the "HS
test ON" mode is also cleared. Once the door is closed Health Safety feature now functions
as if the machine door had been closed for a long period of time and any temperature
value over the HS limit, for the refrigeration mode in use, causes the normal 15 minute HS
limit timer to start a count and if the temperature limit is exceeded for 15 minutes disables
vending from the machine. Refrigeration Modes affected are: Cold, Frozen and MZF
