Tray Remover Forward and Retract Speed Adjustment
Adjust the forward and retract speed as follows using the speed controllers installed on the side of
the STU control box.

Tray Remover Upper Limit Sensor Adjustment
1) Insert a 2 mm clearance gauge so that the remover is elevated.
2) Move the dog to adjust the upper limit sensor so that it comes on in this 2 mm elevated position.
[10-12] Tray Remover Provisional Position Adjustment
1) Set a standard 100-pin size empty tray in the STU tray holder.
2) Advance the remover.
3) Move the remover mount bracket to adjust it so that the center of the remover aligns with the
center of the empty tray.
* Since the STU itself is not servo controlled, the tray remover position must be moved to the center
of the tray dimensions of each tray type. The standard 100-pin size tray is used here for measuring
but other boards should be adjusted to match each tray size.
Use the dog to adjust the
sensor so that it comes on.

[10-13] Tray Eject Sensor Adjustment
1) Loosen the hollow bolt and adjust so that the distance from the top of the sensor mount bracket to
the top of the sensor is 5 mm and so the sensor amp is on.
2) When the transparent tray eject box is set after the sensor has been adjusted, verify that the
sensor light beam is positioned 1 mm above the box.
[10-14] STU Operation Check
1) Transmit a program for placing one tray of QF 100 pin parts to the machine.
2) Check the part name and set the part on the STU.
3) Attach the nozzle to be used on the nozzle holder or on the nozzle change unit.
4) Activate automatic operation and confirm that the STU works properly.
[10-15] Remover Operation Check
Load a 240 g empty tray (maximum allowable weight) on the STU and verify that the remover is
able to hold the tray.
[10-16] Check of Restrictions When STU is Installed
When an STU-1 or STU-2 is set on the MFU there are restrictions that apply to the feeder
positions as outlined below. Verify that the setup is in conformance with these restrictions.

Move up or down to adjust both sensors to 5 mm together.
After adjusting verify that the distance between the top of
the tray eject box and the sensor light beam is 1 mm.

Note: * When an STU-1 or STU-2 is used without installing a reject parts conveyor,
interference space is required as shown in the following examples so do not set
feeders in these positions. If a feeder is set in one of these device positions the
head
and feeder will collide when the STU part is picked.
Example:
When an STU-1 (D1 ~ D9) is set : D10 ~ D12
When one STU-2 (D1 ~ D7) is set : D8 ~ D10
When two STU-2 units (D1 ~ D7, D8 ~ D14) are set : D15 ~ D17
* An STU-1 and STU-2 cannot be loaded on the same MFU.
* When an STU is installed at device positions other than those given in the
examples above, the number of occupied device positions may increase depending
on the unit that is set adjacent to the STU.

STU Rear LED Display
There are LEDs on the rear of the STU to notify the operator of STU alarms, when to supply trays
to set in the STU and when the empty tray eject box is full. Use the explanation for each of the LED
displays given below as a reference.
[POWER]: Indicates that power is being supplied to the STU.
[ALARM]: The contents of the alarm are indicated by the number of times the connected LED
flashes.
