7.0 TROUBLESHOOTING
7.1 OUT OF SERVICE MESSAGE
Certain critical errors will disable the vendor. 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 vendor, 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 vendor 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 occurrence.
7.2 HEALTH AND SAFETY ERRORS
NAMA specifications for perishable food vendors
require that the temperature in the vendor must cool
to 41°F or lower 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
vendor must never remain above 41°F for more than
15 minutes.
For vendors 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, AMS 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 vendor will not allow further sales. This
protects the consumer from purchasing spoiled food.
H&S error codes are detailed in Section 7.3.
The H&S function can be tested by manually warming
the temperature sensor to simulate the failure
conditions (Refer to Section 8.11).
7.3 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. ACCOUNTING 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, ACCOUNTING DATA will
be displayed.
