Generally speaking the timing value is set to the normal vend time. For example, if the vend normally takes 6 seconds to complete, then
set the timing value to 6. This allows for the VMC to ‘expect’ a home signal at the required time and to ignore any spurious signals in
the meantime. It also sets an appropriate delay after a ‘home’ should be expected, disabling power to the motor if this home wasn’t
reached. In this case the motor is inhibited, the appropriate error code is set and the money entered is returned to the user.
The Vend cycle is Voltage and Load dependent so an approximate setting of the timing value needs to be set. The vend cycle, is the
time from motor start (when at home) to motor end (return to Home) in seconds. This translates directly to the timing value that re-
conditions the value for correct operation.
Operation
1. Press the Red Service Button to scroll to
Displays AS.—
2. Press Button 1 (or 2) to increment/decrement Value
Displays AS.** where ** is value 01 to 99
3. Press Button 4 to store Timing Value
Displays set
Notes
-
The current timing value is displayed whilst doing a test as Pl.**, where ** is current value
-
The timing Value can be set from 00 to 99.
-
For Version 1 Motors the default timing value is 7
-
For Version 2 Motors the default timing value is 3
-
The timing value reverts back to default every time a version change is set
-
The timing value cannot be individually assigned and applies to all outputs when set.
-
The VMC will return to Normal Mode (00.00) 60 seconds after the last button has been pressed unless the Red Service Button
has been pressed or the reject is pressed.
Test Sequence
Overview
The VMC constantly tests the operation of the machine, the data stored and the peripherals attached. Every .01 seconds,
a self-test analysis is done to verify correct operation of the machine. Further tests are done on Power Up, Button Press,
Coin Insertion and entering/exiting Service Mode. These tests will generate the relevant fault code as necessary.
However, it is possible to do a thorough analysis through Service Code AP, which will individually test each motor as well
as escrows and other related functions. This is useful to re-align any jammed motors.
