Diagnostic Code 8 -
State Transition History
This test is used to view the state transition log main-
tained by the CPU board. It stores a history of all state
transitions which occur during the operation of the dis-
penser. It is capable of storing the last 40 state transitions
and events that have occurred since the last cold start
(zeroing the RAM).

in the dispenser memory. If no changes in state have
been recorded, the display flashes the message in figure
D-12a.
To enter this test, enter diagnostics and press the 8 button

If there are states recorded, the display is read as in figure
