Discharge/ByPass Conveyors
Ribbon Tension Adjustment
Tension on the discharge ribbons and both
front and rear bypass ribbons should be adjusted
when ribbons sag or tend to track to one side.
These conditions cause excessive wear on the
ribbons and can shorten their life.
Tension adjustment is identical on these three
ribbon sets.
Required Tools
3/8”, 9/16”, 3/4” wrenches, pliers, thin
slotted screwdriver
Perform only when the unit is OFF
with power disconnected.
Turn power OFF at the main disconnect
switch.
Only if the front bypass ribbon set is to
be tensioned:
Turn ON the compressed air supply
to the unit.
Locate the right pneumatic panel (Fig-
ure 7-33) just to the right of the center
of the machine.
On the bottom of this unit is the main
solenoid valve. Locate the override
screw on this valve (Figure 7-34).
Use a small screwdriver to push in
the lockout screw and turn it 1/4 turn
clockwise to lock it in the “in” position.
This allows compressed air to flow to
the pneumatic control solenoids.
On the right pneumatic panel, locate
the solenoid air valve for the front by-
pass conveyor (Figure 7-37) and locate
its lockout screw.
Use a small screwdriver to push in
the lockout screw and turn it 1/4 turn
clockwise to lock it in the “in” posi-
tion. The front bypass conveyor should
rise.
