j. Verify the BASE PERCENT OF MIX is 94% and
the TOTAL PERCENT (REF) is 100%
k. Press and hold the footswitch down. The base
pump and inhibitor pump (1093 valve) will start
to dispense.
l. When the base pump hits the end travel,
release the footswitch; both pumps will reload.
m. When the pumps are reloaded, repeat this
about fifteen times to verify the volume of the
mixer has inhibitor through the mixer and the
material coming out is air-free.
5. Prime the catalyst pump (1093 valve).
a. Turn the air pressure on the catalyst feed pump
so that the actual material pressure is around
300 psi (2.1 MPa, 21 bar). This is an estimate
based on the air pressure on the feed pump and
the power factor of the pump. If pressure trans-
ducers are included (kit 24M127), the catalyst
pressure readout can be seen on either the
STARTUP, STATUS, or PRESSURE LOG
screen.
b. On the DRIVE/VALVE CONTROL screen, push
the SET AUTO MODE button.
c. If a customer supplied screw valve is being
used, push the AUTO SCREW VALVE push
button.
d. Verify all pumps are ENABLED and HOME.
e. Go to the AUTO MODE SETUP screen.
f. Set the TOTAL FLOW RATE to 4-6cc/sec.
g. Set the INHIBITOR PERCENT OF MIX to 6%
h. Set the CATALYST PERCENT OF MIX to 1%.
i. If color is used (Kit 24M126), Set the COLOR
PERCENT OF MIX to zero.
j. Verify the BASE PERCENT OF MIX is 93% and
the TOTAL PERCENT (REF) is 100%
k. Press and hold the footswitch down. The base
pump, inhibitor, and catalyst pump (1093 valve)
will start to dispense.
l. When the base pump hits the end travel,
release the footswitch; all pumps will reload.
m. When the pumps are reloaded, repeat this
about fifteen times to verify the volume of the
mixer has catalyst through the mixer and the
material coming out is air-free.
6. Prime the color pump (1093 valve). Valid only if
kit 24M126 is being used.
a. Turn the air pressure on the color feed pump so
that the actual material pressure is around
300 psi (2.1 MPa, 21 bar). This is an estimate
based on the air pressure on the feed pump and
the power factor of the pump. If pressure trans-
ducers are included (kit 24M128), the color
pressure readout can be seen on either the
STARTUP, STATUS, or PRESSURE LOG
screens.
b. On the DRIVE /VALVE CONTROL screen, push
the SET AUTO MODE button.
c. If a customer supplied screw valve is being
used, push the AUTO SCREW VALVE push
button.
d. Verify all pumps are ENABLED and HOME.
e. Go to the AUTO MODE SETUP screen.
f. Set the TOTAL FLOW RATE to 4-6cc/sec.
NOTICE
After the catalyst has been added, the material is
able to cure. To avoid machine damage from long
idle times, perform a
Base Purge , page 19.
