Activation (Operate)
Switches
Located on either side of the base are two optical (RUN)
switches. These are shown in Figure 4-13. These switches
use Infrared (IR) sensors. They comply with OSHA and
CE safety standards. Both switches are identical.
Each optical–touch switch has a small red LED that is dimly
illuminated whenever the power is on, as shown in Figure
4-14. When the operator places a finger in the tray, the LED
brightens and a second LED in the opposite corner of the
tray illuminates to indicate the switch has been activated
as shown in Figure 4-15. Both switches must be activated
simultaneously to initiate a weld cycle.
Emergency Stop (Abort)
Switch
A red Emergency–Stop (E-STOP) switch is located in the
center of the base as shown in Figure 4-13. The emergency
stop switch must be in its reset position before the operate
switches will function.
To reset the Emergency Stop, twist the large red button
about 45 degrees to the right, which will cause the button
to spring out. This is shown in Figure 4-16.
The abort switch applies 24 VDC power to the thruster/
press. Pressing the abort switch causes the press to:
• Immediately turn off the ultrasound,
• Remove electrical power from the press, and
• Initiate a software abort sequence.
Front Panel Status LEDs
The function of these LEDs is to indicate the status condi-
tions of the press:
POWER
• - A green POWER status light indicates
that power is applied to the press, and it is ready for
operation.
ABORT
• - When the E-STOP (abort_ switch is pushed
in, the red ABORT status indicator illuminates. Press
operation is no longer possible.
TRIGGER
• - The blue Trigger light comes on when-
ever Ultrasound turns on. It is activated by the Trigger
Switch or at the beginning of the weld cycle if "Pre-
trigger" is enabled.
