1.1 Air regulator unit
1.1.1 Supply air pressure
The air regulator for controlling the air pressure to the machine's pneumatic units is located at the lower left
panel on the front side of the machine. Specify the appropriate air pressure setting shown below.

Supply air pressure
This is the pressure of the source air supplied to the machine. Before setting the air pressure with the
air regulator, make sure that this supply air pressure is in the following optimal range.
YRM20 : 0.45MPa or more
►
Air pressure gauge
When within the normal range, the air pressure displays in green. When the air pressure is beyond
the upper/lower limit values (air down detection), an error occurs, and the air pressure displays in
red.
►
Set air pressure and air down detection
Set air pressure for main machine : 0.40MPa (0.39MPa~0.41MPa)
(When it achieves 0.45MPa, the air pressure gauge displays in
red.)
Air down detection pressure : 0.33MPa
►
Air supply/shutoff swith (valve)
Turning this switch to the right shuts off air supply and exhausts air that remains inside the machine.
►
Source air connector
Prepare an air hose with an inner diameter of at least 8 mm having a 40SH socket (Nitto Koki, or
equivalent), and connect it to this connector. Use dry, clean air passed through an air filter.

WARNING
TO AVOID THE RISK OF ELECTRICAL SHOCK, MAKE SURE THAT THE POWER SOURCE IS OFF BEFORE CONNECTING THE
POWER CABLE. ALSO MAKE SURE THAT THE GROUND CABLE IS SECURELY CONNECTED TO THE MACHINE.
c
CAUTION
Use a power cable whose conductor cross-section area is greater than 6.0mm
2
.
c
CAUTION
By referring to the figure above, be sure to connect the power cable correctly to the L1, L2 and L3 terminals on the power
input terminal block so that they are in the normal phase. Incorrect connection may cause the vacuum pump to turn in the
wrong direction and drastically damage to the components in the vacuum pump.

1.3 Connection between machines
To exchange signals such as board request and operation status with the downstream or upstream machine,
the "NEXT INTERFACE" and "PREVIOUS INTERFACE" connectors located on the rear of the machine are
used.
The "NEXT INTERFACE" connector connects to the downstream machine, and the "PREVIOUS INTERFACE"
connector connects to the upstream machine such as a loader.
At the standard "R to L" flow line, the PREVIOUS INTERFACE is located on the observer's left and the NEXT
INTERFACE on the right.
Both connectors use AMP206043-1 (14 pin, receptacle).
