1) Using a cutter knife, cut the centers of the grommets that
come with the robot arm. Install the grommets through the
connectors coming out of the rear of the No. 2 arm.
2) Using the screw holes on the rear of the No. 2 arm, firmly
install the solenoid valve box with the mounting screws
(M4 x 10: 4 pcs) that come with the product. Be sure to
securely tighten the screws so that they do not interfere
with the robot arm.
3) Loosen the mounting screws (M4 x 8: 4 pcs) of the
solenoid valve from the solenoid valve box, and remove
the solenoid valve.
4) Using a cutter knife, cut the centers of the grommets
located on the bottom of the solenoid valve box. Feed the
connectors (GR1 and GR2) coming out of the rear of the
No. 2 arm through the grommets, and connect them with
the hand output cable connectors (GR1 and GR2) coming
out of the solenoid valve.
5) Pull out the air hose (φ6, provided by the customer)
coming out of the port P of the solenoid valve from a
grommet located on the bottom of the solenoid valve box.
If air ventilation is required to satisfy the clean
specification, connect an air hose (φ6, provided by the
customer) to the port R of the solenoid valve, and pull it
out from a grommet in the same manner.
6) Install the solenoid valve back in the original position, and
securely tighten it with its screws. Be careful not to pinch
cables while in this installation operation. Also, be sure
that no gap is created between the solenoid valve box and
the solenoid valve by the sponge sealant applied onto the
solenoid valve. If there is a gap, the protection
specification may degrade.
* In the case of the oil mist or clean specification, fill the
surrounding areas of the grommets as well as the outlets of
the cables and air hoses with silicon rubber.
7) Connect the air hose (port P) pulled out of the solenoid
valve box to the coupling (AIR OUT) on the robot arm side.
Also, if the port R of the solenoid valve is used, connect
that air hose to the coupling (RETURN) on the robot arm
side. In this case, remove the dustproof cap attached to
the RETURN air coupling (φ6) in the rear of the robot's
base section. If the robot is operated with this cap on, the
exhaust air pressure increases and the solenoid valve may
not function normally. Additionally, the exhaust air from
the solenoid value can be relieved to the designated
location by connecting an exhaust hose to the RETURN
air coupling (φ6, provided by the customer).
