1.1 Air regulator unit
The air regulator for controlling the air pressure to the pneumatic units of the machine is located behind the
front lower left panel. A digital pressure gauge is provided on the front left of the machine. The air pressure
must be set to the optimum level.

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.

Air supply/shutoff switch (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 8mm having a 40SH socket (Nitto Koki, or equivalent), and connect
it to this connector. Use dry, clean air passed through an air filter.

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. In the case of standard right-to-left flow, the
PREVIOUS INTERFACE connector is located inside the lower right cover on the rear of the machine while the
NEXT INTERFACE connector is located inside the lower left cover on the rear of the machine.
1.3.1 PREVIOUS INTERFACE connector
When the following three conditions are satisfied, the PREVIOUS INTERFACE circuit in the machine allows the
next board to be carried in. (ADVANCED GATE is selected.)
1. Machine is ready for carrying in a board. (BUSY OUT: ON)
2. Board carry-in signal is input from the upstream machine. (BA IN [N01007A1] : ON)
3. Auto operation signal is input from the upstream machine. (UR IN [N01007A3] : ON)
n
NOTE
• When the auto operation running signal (UR IN) from the loader turns off during board carrying-in, the machine
temporarily stops carrying in the board.
• When the board being carried in is detected by the entrance sensor, the BUSY OUT signal turns off.
• Carrying in the board is nished when both the BUSY OUT and BA IN turn off.
