2. ALL VALVES:
a. ENABLE/DISABLE DRIVES: These push but-
tons work the same as the ENABLE/DISABLE
DRIVE push buttons for each individual compo-
nent, they just enable all the pumps or disable
all the pumps at the same time. The
enabled/disabled status is indicated in each
individual component.
b. DRIVE FAULT RESET push button: If there is a
drive fault (indicated in the status of each com-
ponent or in the upper right corner of any
screen), pushing the drive fault reset button will
reset the fault.
c. DRIVE SHUTDN RESET push button: Neces-
sary to reset the drive for certain faults if shut
down. Use this push button to reset the drive if a
fault shuts down the machine.
d. SET AUTO/RATIO/MAN'L mode push buttons:
These are used to set the machine mode. When
connected to the press the mode should be set
to auto mode. Push the SET AUTO MODE push
button. In auto mode, the button color will
change from gray to green and will read “IN
AUTO MODE”. The ratio check and manual
modes are set the same way. The ratio check
mode is used to run a pump individually and the
manual mode is used for manually toggling
valves when priming.
e. OPEN/CLOSE/AUTO SCREW VALVE push
buttons and indicator. These buttons are used
to setup the customer supplied valve between
the outlet of the mixer and entrance of the
screw. During normal running in auto mode the
valve should be set to AUTO by pushing the
AUTO SCREW VALVE push button. The indi-
cator beneath the push buttons will read
“AUTO”. The valve is set to be held open or
closed by pushing the OPEN or CLOSE
SCREW VALVE button. The valve should be
held open or closed for priming and clean out.
f. RESET OVERTRAVEL FAULT push button
(only visible when supervisor is logged in). This
is one method used to reset an over travel fault
which occurs when a pump axis goes beyond
the defined range.
g. Status box in lower right corner (only visible
when supervisor is logged in): This is used for
additional troubleshooting. The status box dis-
plays the actual motor position, actual motor
speed, pressure and motor torque while running
for each component.
NOTE: Negative speed or torque value indicates the
motor is moving in thee negative direction. The position
for home is 0.0, +/-.02 for the base, +/-.002 for the inhib-
itor and catalyst.
