Normal operation is the state of the machine when the machine control circuit is energized and
the
Run/Program
keyswitch is in the
Run
position. The machine may be either idle (waiting to
run a formula) or running. If the machine is idle, the message on the display will begin with “Run
Formula” and include a formula number on the second line.
1. Push the
Start button
(
) to start the wash formula. The formula begins if the machine
has power and the door is closed. To see the status of the microprocessor inputs, hold the
Start button
and push the
Scroll Up button
.
2. The
Run/Program keyswitch
must be in the
Run
position (
) unless the machine is being
configured or programmed. All control descriptions listed under
During Normal Operation, page 15
are based on the keyswitch being in the
Run
position. See
2.1.3: Control Functions During Programming, page 18
for descriptions of how the controls
operate with the keyswitch in the
Program
position (
).
3. The
Run Indicator light
, in the upper left corner of the
Start button
, lights when a formula
is started by pressing
. If the operator stops the formula before it stops automatically, the
light goes off when any coast time expires and the control unlocks the door. If the formula
runs to completion, the light goes off when the coast time following the final extract step
expires.
4. When selecting a specific formula to run, press the
Scroll Down button
(
) to display the
next lower numbered formula in memory. Push this button with the lowest formula displayed
(Formula 01) to select the highest numbered available formula (maximum of 30 formulas).
For troubleshooting, hold the
Manual button
and press the
Scroll Down button
to view the
status of the second 12 outputs.
5. The display on these machines is a vacuum fluorescent type displaying two lines of twenty
characters each.
6. The
Scroll Up button
(
) functions in much the same manner as the
Scroll Down button
described above. Push this button to display the next higher numbered formula in memory.
For troubleshooting, hold the
Manual button
and press the
Scroll Up button
to view the sta-
tus of the first 12 outputs. Hold the
Start button
and press the
Scroll Up button
to view the
status of the microprocessor inputs.
7. The
Next button
(
) is used during normal operation only for troubleshooting. Holding the
Signal Cancel
,
Manual
, and
Next buttons
simultaneously displays the raw pressure data and
the actual number of inches detected by the bath level pressure transducer.
8. Push the
Signal Cancel button
(
) to silence the operator signal buzzer which sounds when
a formula completes normally. Also, if a signal is programmed with a chemical injection in
any formula, this button must be pressed to indicate that the chemical has been added and to
resume operation. For troubleshooting bath level problems, hold the
Signal Cancel
,
Manual
,
and
Next buttons
simultaneously to display the raw pressure data and the actual number of
inches detected by the bath level pressure transducer.
9. The
Operator Signal light
, in the upper left corner of the
Signal Cancel button
(
), is a
visual indicator that operator attention is required. This light is illuminated simultaneously
with the sounding of the operator signal buzzer.
