Conveyor unit and air supply unit adjustment
1.1 Adjusting the air valve
The air valve of each conveyor unit mechanism is located inside the lower
right panel on the back of the machine. Air drive speed can be adjusted by
turning the speed controller knob connected to each air valve.

Conveyor unit and air supply unit adjustment
1 Open the output monitor in MANUAL mode.
Select <3/4/A1 INPUT/OUTPUT MONITOR> - ”SELECTION” -
“CONVEYOR” and press the [ENTER] key.
2 Check the speed of the conveyor unit you want to adjust.
Use the arrow keys to line up the cursor with the desired unit and press
the [ENTER] key.
The selected unit turns on and off each time you press the [ENTER] key
and the digit on the output monitor changes to “1” or “0”. The speed
should be around one second (speed at which components mounted on
the PCB in the preceding process do not shift).

3 Press the emergency stop button, then adjust the speed.
Loosen the lock nut and turn the speed controller knob for the orange tube
to adjust the ascent speed, or turn the speed controller knob for the black
tube to adjust the descent speed. In either case, turning the knob to the left
increases the speed, while turning it to the right decreases the speed.
n
NOTE
The main stopper must ascend slightly earlier than the locate pins.
The ascent speed of the fixed locate pin should be slightly higher than the movable locate
pin.
4 Tighten the speed controller lock nut .
Use the same procedure when adjusting the operation speeds of other
conveyor units.

Conveyor unit and air supply unit adjustment
1.2 Conveyor speed
The conveyor speed varies according to the frequency of the power supply
and the weight of the PCBs on the conveyor. You can adjust the carry-in
and carry-out conveyor speeds by using the adjustment screws located
inside the lower right panel on the front side.
The YV180X conveyor section is divided into 4 conveyors: carry-in
conveyor, B-table conveyor, A-table conveyor and carry-out conveyor. The
carry-in and carry-out conveyors each move at two different speeds: a high
speed (H) for reducing the transfer time of PCBs and a low speed (L) for
minimizing impact when the PCB hits the entrance stopper and exit
stopper. To adjust these speeds, prepare typical PCBs and use the proce-
dure below.
