3Installing the option devices
It is necessary to set the parameters (HIOTYPE, HANDYPE) in accordance with solenoid valve type (sink type/
source type) and output signal before using the solenoid valve set.
Refer to the separate volume, "Instruction Manual/Detailed Explanations of Functions and Operations" for how to
set parameters.
1) Install the solenoid valve set <1> on the No.2 arm side. Fixing at the T slot on the No.2 arm side with two fixing
screws and two nuts attached for T slots. Install in the position of 10mm from the arm end.
2) Connect the hand output cable within No.2 arm. Makes notch or removes in one of grommet near a solenoid
valve. (Following)
a) General environment: ......makes notch. (draw in a hand output cable from here)
b) Clean/ Waterproof: ..........removes (fixes a hand output cable here by a cable clamp)
3) Loosen the fixing screw and remove the No.2 arm cover <3> and the arm cover A(2) <12>. Since the air tube
is connected, No.2 arm cover <3> is completely inseparable.
4) Pass the hand output cable <4> of the solenoid valve set to No.2 arm cover.
a) General environment: ......pass it to grommet <2> in which the notch was made.
b) Clean/ Waterproof: ..........fixes it to the hole which removed the grommet by an attached cable clamp.
5) Connect with hand output cable (GR1, GR2) <5> of the robot arm side in No.2 arm. Connect the same
connector names.
Note : Please see the hand output cable from the arm cover A (2) <12> side, and store it outside the bracket. If
the cable enters within the bracket, it will rub to the timing belt and will become the cause of breaking
down.

6) Install the No.2 arm cover <3> and the arm cover A(2) <12> as before. Be careful not to catch any the cables.
7) Connect primary air piping with the two φ6 air hoses (customer preparation). Connect between the "R" port
(6) of the solenoid valve set and the "RETURN"<8> on No.2 arm cover, and between"P" port <7> and
"AIROUT"<9>.
8) Connect secondary air piping with the φ4 air hose (customer preparation).
There are two connection methods as follows.
a) Connect with the tools of customer preparation direct from the solenoid valve set. The fixing place of
the air hose which can be used of the customer is shown in
b) Connect via the air hose piped in robot arm previously.
Note: In the robot arm, fourφ4 air hoses are piped to the secondary piping air joint in motor cover J3
<11> from the secondary piping air joint of J2 axis upper part <10> previously.
(If more numbers of piping are necessary, please pipe to the tools directly)
And, please prepare separately the air hose for connection from the secondary piping air joint <11>
to the tools. (The conversion coupling is attached(φ4 to φ3))
<Reference> : The air hose which can be passed in the shaft is four φ4 hoses maximum. If you utilize

Pass the hand output cable to the attached cable clamp , and pass to the hole
of No.2 arm cover, and pass to the lock nut , and fix it to No.2 arm cover by
lock nut surely.
Cable should be stored in
outside of the bracket.
