2.5.5 Air supply circuit example for the hand
An example of pneumatic supply circuitry for the hand is shown below.
1) Make sure that a surge voltage protection circuit such as a diode is connected to the solenoid coil in
parallel.
2) When the factory pneumatic pressure drops, as a result of the hand clamp strength weakening, there
can be damage to the work. To prevent it, install a pressure switch to the source of the air as shown
in
Fig. 2-8
with a spring-pressure clamp, or a mechanical lock-type hand, that can be used in cases where the
pressure switch becomes damaged.
3) If the air supply temperature (primary piping) used for the tool etc. is lower than ambient air tempera-
ture, the dew condensation may occur on the coupling or the hose surface.

2.5.6 About the Installation of Tooling Wiring and Piping
The customer should supply all wires, hoses, and fixtures for tooling.
Adjust the installation position and the length of wires and hoses to suit the movement of the robot.
After connecting all wires and hoses to the robot, run the robot at low speed and check that the wires and
hoses do not interfere with any part of the robot or peripheral devices.
