Troubleshooting
When FASI is enabled, a FASI signal to enable lasing must be connected to input IN3. If not, Flyer will
not send PWM Commands signals to fire the laser and the Status LED starts blinking red at a fast rate. If
IN3 goes low while marking a piece then the mark is not completed.
Symptom:

Flyer boots up normally (Pwr and Status LED’s are solid green), but after the servos are initialized, the
Status indicator begins flashing red at a slow (2 Hz) rate and marking is halted.
Possible Causes:
 Flyer detected a fault in the optical scanner system.
Remove power, wait 30 seconds, and then reapply power. If the fault re-occurs after the servos are initial-
ized, then contact SYNRAD Technical Support.
Symptom:

The Status indicator is red.
Possible Causes:

If the Status LED is solid red, not blinking, this indicates a fatal, non-recoverable, fault has occurred.
Remove power, wait 30 seconds, and reapply power. If the fault re-occurs, contact SYNRAD Technical
Support.

A solid red, not blinking, Status LED may indicate that the field reprogramming procedure was at-
tempted, but DIP switch # 4 on switchbank SW2 was not switched back to the OFF position.
Refer back to Service Bulletin #08 and complete or restart the reprogramming procedure. If the fault re-
occurs, contact SYNRAD Technical Support.
Symptom:

WinMark Pro v6 is installed, Flyer is powered up, Pwr and Status LED’s are green and the USB Com-
munication cable is connected between FH Flyer and the computer, but WinMark Pro v6 does not
“see” the FH Flyer marking head. The “Search for heads again” option does not locate the head, forc-
ing WinMark Pro v6 to open in demo mode with the Mark button grayed out.
Possible Causes:

FH Flyer’s USB device driver is not installed.
In the Windows
®
Control Panel, open the Add Hardware Wizard and follow the instructions to scan for
new Devices and install the appropriate Device Drivers. If this fails, restart your computer and/or
reinstall WinMark Pro v6 Laser Marking Software. The first two screen shots in Figure 7 -3 show that a
hardware device exists, but a corresponding driver is not installed. The screen shot on the right shows
the Flyer Laser Marking Device is properly installed and functioning.
