1
Disconnect and lockout the main power supply, and the air supply from the
blender.
2
Remove existing manual FCV from the rear of the blender.
3
Install the automatic version in its place using the original hardware or the new
supplied hardware.
Use removable strength Loctite when installing hardware to
make sure that the bolts do not work loose.
4
Open the blender door and remove the front plate and mixer from the unit.
Manually push the slide gate back and then bring it forward to determine where the
front of the slide gate ends relative to the opening in the bottom of the mixing cham-
ber. It should just seal off the hole in the mixing chamber – there should not be a
hole large enough where the material can leak by and it is important that the slide
gate does not run past the mixer opening or material binding could occur. If this is
not correct continue to step 5. (Note the FCV is adjusted at the factory and should
be adjusted correctly for most blenders). If set correctly continue to step 6.
5
Remove the slide gate from the blender, remove the cover from the FCV
and
loosen lock nuts that adjust the length of the assembly as required from step 4. Re-
install assembly and re-check mixing chamber closing. Once the length is correct,
place a small amount of Loctite on the locknuts and re-assemble the FCV on the
chassis.
6
Open the control box enclosure door and route supplied tubing through the
holes on the right side of the box.
7
Remove the existing plugs from the last solenoid on the stack.
Connect the hose
that goes to the rear of the cylinder to the bottom of the valve stack and connect the
hose (4) that goes to the front of the cylinder to the top of the valve stack. Make
sure that the hose is fully seated into the fitting.
8
Close control box door and re-connect the air and power to the unit. Make sure
no leaks are present.
9
Place the blender manual mode and operate the FCV.
Make certain that the valve
is operating the way the manual indicates (if indicates open valve is open and if indi-
cates closed the valve is closed). If not correct switch hoses inside the control box.
10
The valve should retract at full speed and extend fully in about one second.
If
this is not set correctly loosen the locking nut (12) on the throttling valve on the front
of the cylinder and adjust as necessary. Once this is adjusted correctly re-tighten the
locking nut to make sure that this speed does not change.
