3c. By hand, move the Socket Opener down until the opener ribs
open the socket completely. See Figure 4-5.

(Optima Socket Adapter shown.)
3d. Loosen the Phillips-head screw on the down sensor bracket.
3e. Move the down sensor downward until the red LED on the sen-
sor lights.
3f. Tighten the sensor bracket screw.
3g. On the Power Panel, rotate input air valve ON (counterclock-
wise).
3h. At the Gantry window on the monitor, click the Actuate Socket
toggle OFF and ON several times to verify that the LED turns off
and then on.
Adjusting the Socket Actuator Air Pressure
PS588 FlashCORE is the only programmer with socket actuation built
into the programmer. Other actuators, commonly called Openers, are
on the PNP head.
Pressure for Actuators on PNP Head
[PS288, PS388 and Optima Programmers only on PS588] If the PNP
head does not properly pick or place a device in a socket because the
socket is not opening completely, the Socket Actuator air pressure
might be set too low.
Note: Prior to adjusting the actuation pressure, the opener ribs
must be adjusted for proper contact with the socket. See Adjust
Socket Opener Ribs on page 3-14.
To adjust the Socket Actuator air pressure:
1. Preparation—
1a. Pause any job that is running.
1b. At the Gantry Window, move the head to a programmer by click-
ing P1, for example.
1c. Click the Actuator tab.
1d. Click the Actuate Socket switch to ON (green).

2. Power Panel—
2a. Verify that the Socket Actuator pressure regulator (on the back
Power Panel) is set within this range:
• Standard Sockets, 1.3 ±.34 Bar (20 ±5 PSI), and for
• HIC sockets, 2.2 ±.55 Bar (32 ±8 PSI).
CAUTION: Possible excessive socket wear. Setting the Socket
Actuator air pressure too high can cause premature wear of the
sockets.
2b. If experiencing problems, increase the Socket Opener air pres-
sure slightly to the high end of the range.
2c. Open and close the socket to check that it opens with one stroke
of the opener.
3. Restart Job—
3a. Restart the job and check the action of the Socket Opener and the
pick and place performance.
Pressure for Actuators on the Programmers, PS588
[PS588 Machines with FlashCORE] Actuators are part of the pro-
grammer. If Socket Actuators are moving too fast or too slowly, or
you are experiencing pick or place problems, contact Data I/O sup-
port or a qualified technician.
Adjusting the Socket Opener Speed
Prior to adjusting the actuator speed, the actuator pressure should be
set (see the previous heading).
Speed for Openers on the PNP Head
[PS288, PS388 and Optima Programmers only on PS588]
Note: Prior to adjusting the opener speed, the opener ribs must be
adjusted for the current socket. If this has not been done, see Adjust
Socket Opener Ribs on page 3-41.
To adjust the Socket Opener speed:
1. Preparation—
1a. Ensure that power and air are connected and ON, and a Socket
Adapter is installed.
1b. At the Gantry Window, click the label for a programmer with
easy access. The head will stop over socket 1.

2. Adjust the down speed—
2a. Open the safety door nearest the PNP head and locate the in-line
air flow control for the upper end of the air cylinder on the head.
See figure below.
Figure 4-6: Flow controls for the Socket Opener Speed control. (PS288,
PS388 and Optima only on PS588.) (Your head assembly may not look
like this one.)
2b. Loosen the locking ring and adjust the down flow control as 1/2
to 1 revolution clockwise for slower or counter-clockwise for
faster.
2c. Close the Safety Door, and clear the Safety Door warning on the
monitor.
2d. At the Actuate tab of the Gantry Window, click the Actuate
Socket toggle switch to ON while listening and watching the
opener.
If it is too fast it will produce a louder thump than optimum
when it opens the socket.
If it is too slow it will look slow.
2e. Click Actuate Socket OFF.
2f. Adjust the flow control as necessary and repeat the test.
2g. Tighten the locking ring when done.
3. Adjust the up speed—
3a. Follow the same procedure as above with the other flow control.
