3Installing the option devices
Installing the solenoid valve set 3-69
2) Installs the air hose.
(only internal wiring and piping specification)
Connects the port A/B of solenoid valve to use and the coupling on the front side installed by above-
mentioned
with air hoses (φ4).
3) Loosen the fixing screws (M4x12) and detach the No.2 arm cover U (forearm upside) and the No.2 arm cover
L (forearm side face).
(standard/internal wiring and piping specification common)
The connectors (GR1, GR2), φ4 secondary piping air hoses (4), and the AIR IN (φ6, white) and RETURN
(φ6, black) primary piping air hoses are set inside the forearm.
* The figure is an example which connected the first and second solenoid valve.
No.2 arm cover U
(M4 ｘ 12, (four screws)
Thermal conductive sheet
After the cover is removed, take
care not to damage the thermal
conductive sheet or timing belt.
CAUTION
Timing belt
Forearm top
φ4 air hose for secondary piping
first - fourth (A total of four)
(only internal wiring and piping specification)
AIR IN (φ6, white)
Connector
(GR1, GR2)
RETURN (φ6, black)
Do not cut the cable tie that bundles
the cables inside the arm.
Doing so may loosen the fixed
cables, resulting in interference with
the timing belt.
CAUTION
No.2 arm cover L
(M4 ｘ 12, five screws)
The thermal conductive sheet is
adhered closely to the No.2 arm
cover L. To prevent the thermal
conductive sheet from coming off,
detach the cover slowly and firmly.
When the sheet comes off, reattach
it to the original position.
CAUTION
Take sufficient care to prevent for
-
eign matters (cut chips of air hoses,
etc.) from entering the robot.
CAUTION
Do not cut this cable tie.
