2.1 PREVIOUS INTERFACE circuit
When the following three conditions are met, the PREVIOUS
INTERFACE circuit in the mounter allows the next PCB to be carried in.
1. Machine is ready for carrying in a PCB (BUSY OUT: ON)
2. PCB carry-in signal is input from the upstream machine.
(BA IN [N1115]: ON)
3. Automatic operation signal is input from the upstream machine.
(UR IN [N1117]: ON)
n
Note
• When the automatic operation signal (UR IN) from the upstream machine turns off
during
transfer of a PCB, the machine temporarily stops carrying in the PCB.
• When the PCB being carried in is detected by the entrance sensor, the BUSY OUT signal
turns off.
• Carrying in the PCB is finished when both the BUSY OUT and BA IN turn off.

2.2 NEXT INTERFACE circuit
When the following three conditions are met, the NEXT INTERFACE
circuit in the mounter allows the PCB to be carried out.
1. Machine is ready for carrying out the PCB (BA OUT: ON)
2. PCB carry-in signal is input from the downstream machine.
(BUSY IN [N1113]: ON)
3. Automatic operation signal is input from the downstream machine.
(LR IN [N1116]: ON)
n
NOTE
• When the automatic operation signal (LR IN) from the downstream machine turns off
during
transfer of a PCB, the machine temporarily stops carrying out the PC.
• When the PCB being carried out is detected by the exit sensor, the BA OUT signal
turns off.
• Carrying out the PCB is finished when both the BUSY IN and BA OUT turn off.
