4-3. CHANGING DIRECTION OF CONVEYOR TRAVEL
1. Machine with Reverse Switch (optional)
(1) Constant-speed Type
To change direction of conveyor travel, operate the reverse switch of control unit.
NOTE: Before operating reverse switch, be sure to stop the conveyor by setting RUN/STOP switch on
operating panel to “STOP” position.
(2) Brushless-inverter Variable-speed Type
To change direction of belt travel, slide the reverse switch on inverter operating panel from CCW to
CW (or from CW to CCW).
NOTE: Before operating the reverse switch, be sure to stop the conveyor by setting RUN/STOP switch
on operating panel to “STOP” position. (For brushless -inverter, if the set position of reverse
switch is changed while RUN/STOP switch is in “RUN” position, belt running will be rapidly
reversed and the inverter may trip due to inertia of load. In this case alarm LED will be
illuminated in red.)
2. Machine without Reverse Switch
To change direction of belt travel, remove control box cover and change electrical wiring connections as
follows:
■ Control Box Cover Removal
Loosen cover fixing bolts(*1)(one bolt on each side) and remove the cover(*2) sideways. (If difficult,
remove the entire control box from frame, and then remove fixing bolts and cover. In this case do not
loosen any of the other bolts on sides of control box.)
Changing Electrical Wiring Connections (constant-speed type):
Connector(*3) is found in center of base plate inside box cover(*2). Press down hook(*4) on the top with
your finger and disconnect connector(*3) from base plate. Then replace it with connector(*5), which is
attached to connector(*3). (Connectors(*3, *5) can be identified by lead wire colors, red or white.)
