With the reference pin in 1.5 0/-0.5 mm lowered position, loosen the adjusting screw and move the sensor bracket up and
down to activate the sensor; then, at that point, secure the sensor bracket in position.
1. The sensor is to be activated when the reference pin lowers 1.5 0/-0.5 mm.

1. Detects that the centering pin does not fit into the reference hole.
1. The centering pin does not fit into the reference hole, which means that the components are transported with the PWB
incorrectly positioned, resulting in the components being placed at wrong positions.

QA Table
Mount a dial indicator to camera bracket D of the head. When the measurement point indicated below of transport rail F
becomes parallel with X-axis to //|0.1, tighten base bar B set screw (SL6104042TN).

1. Matches the placer coordinate axis with the transport direction.
1. The position of the head in X-direction determines deviation of the transport unit from the PWB in Y-direction, resulting in
variations in placement positions.

UP: From the point at which solenoid is energized to point at which UP sensor is activated: 700 ms ±20 ms
Observation point on PWB:
Solenoid energized -> TP6 (red)
UP sensor activated -> TP2 (white)
DOWN: From the point at which solenoid is deenergized to point at which DOWN sensor is activated: 600 ms ±20 ms
Observation point on PWB:
Solenoid deenergized -> TP6 (red)

Adjust speed controller B shown on the right to prevent the table from suddenly falling down at the start of its downward motion.
5. Rail guide shaft height: 87 ｱ0.1 (See Fig. on the right.)
1. BU table up-and-down movement reference position
2, 3. Degree of shock absorbing upon collision between BU table and rail guide shaft
4. Degree of shock absorbing at PWB clamping. Transport tact time adjustment. Shock absorbing during downward motion of
BU table.
5. Transport rail raising height adjustment.
1. Too high: Guide block interfering with damper plate. The reference pin protrudes a lot from the reference hole.
Too low: The transport rail does not clamp the PWB. The BU pin does not reach the PWB. The reference pin is shallow in the
reference hole.
– BU table height adjustment: Loose NM6080003SC and turn the BU damper collar to adjust the height of the table.
– BU table cylinder speed adjustment: Turn down or back off the adjusting screw. After the adjustment has been made,
secure the fixing nut with pliers or similar tool.
2, 3. Orifice too wide, absorber too high: The table collides with the rail severely, deviating the components on the PWB.
Orifice too narrow, absorber too low: The table moves up at a very slow speed, resulting in greater transport tact time.
4. Table speed too high: The table collides with the rail guide shaft severely, deviating components on the PWB.
Table speed too low: Increased transport tact time.
5. Too high: Increased PWB clamping pressure. BU pin pushing up PWB.
Too low: The transport rail does not clamp the PWB. The BU pin does not reach the PWB.
