RVV Gen II KO Service and Parts Manual
SECTION 3: Vender Programming
•
Test Diagnostics
Pressing <enter> at the “Test Diagnostics” prompt will
cause the controller to enter the diagnostic test routine.
The display will show “Perimeter Test.” Use <up>
or <down> to cycle through the available diagnostic
tests. The door can be shut while in this part of the
service menu.
Note:
If no activity is noticed after five
minutes, the controller will exit the service menu.
Note: If the DMC does not support the diagnostics
command or the vender is currently busy and cannot
respond to the diagnostics command, “Unavailable”
will be displayed upon the initiation of the test. If
the door is not in the correct state for this test to be
carried out, either “DOOR MUST BE SHUT” or
“DOOR MUST BE OPEN” will be displayed upon
initiation of the test. If the test could not be carried
out for any reason, the test must be reinitiated in order
to try again. The system does not auto-detect that the
problem has been fixed.
1.
Perimeter Test
Pressing <enter> at “Perimeter Test” will
cause the vender to move the cup around the
perimeter of the vending area once. This allows
service personnel to observe if there are any
obstructions around the perimeter of the vender
that would inhibit vending. “Testing” will be
displayed while this test is carried out. “Test
Complete” will be displayed when the vender has
completed this test. This is purely a visual test.
Pressing <exit> will terminate the test.
Note:
The perimeter test will only start if the door is
CLOSED.
2.
Delivery Test
Pressing <enter> at “Delivery Test” will cause
the vender to move the cup to the delivery
position and attempt a delivery. If no product is
dispensed, the vender will attempt to deliver two
more times. This allows service personnel to
observe if there are any obstructions around the
delivery position of the vender that would inhibit
vending. “Testing” will be displayed while
this test is carried out. “Test Complete” will be
displayed when the vender has completed this
test. This is purely a visual test. Pressing <exit>
will terminate the test.
Note: The delivery test
will only start if the door is CLOSED.
3.
Cup Test
Pressing <enter> at “Cup Test” will cause the
vender to actuate the plunger in the cup. This
allows service personnel to observe if there are
any problems with the cup plunger that would
inhibit vending. “Testing” will be displayed
while this test is carried out. “Test Complete”
will be displayed when the vender has completed
this test. This is purely a visual test. Pressing
<exit> will terminate the test.
Note: The cup test
will only start if the door is OPEN.
4.
Sensor Test
Pressing <enter> at “Sensor Test” will display in
real time the settings of the sensors on the DMC.
The following will be displayed:
MAG (0/1) Y (0/1) CS (0/1)
PDOOR (0/1) BIN (0/1)
a.
MAG
corresponds to the Hall Effect home
sensor that is used for finding the home
position in the X-axis.
b.
Y
corresponds to the Y-axis home sensor.
c.
CS
corresponds to the cup sensor.
d.
PDOOR
corresponds to the port door.
e.
BIN
corresponds to the delivery bin.
f.
(0/1) corresponds to the sensor’s state: “0” =
off, “1” = on.
This allows service personnel to observe if there
are any problems with any of the sensors on the
DMC. Pressing <exit> will terminate the test and
return the display to “Sensor Test.”
Note: The
sensor test can be performed with the door OPEN
or CLOSED.
5.
Motor / Encoder Test
Pressing <enter> at “Motor / Encoder Test” will
display in real time the encoder counts of the cup’s
position. Pressing <up> will move the cup +450
encoder ticks, or +1 foot (+305 mm), in the Y-axis
direction. Pressing <down> will move the cup
-450 encoder ticks, or -1 foot (-305 mm), in the
Y-axis direction. Pressing <right> will move the
cup +300 encoder ticks, or +6 inches (+153 mm),
in the X-axis direction. Pressing <left> will move
the cup -300 encoder ticks, or -6 inches (-153 mm),
in the X-axis direction. If the encoder’s count is
off by more than +/-3 ticks from what is expected,
there is a problem with the motor / encoder.
Pressing <exit> will terminate the test, home the
motors, and return the display to “Motor / Encoder
Test.”
Note: The motor / encoder test can be
performed with the door OPEN or CLOSED.
