SYNRAD FH Series Flyer Operator’s Manual Version 3.4
Troubleshooting
After boot-up, when the optical scanners are activated, you may hear a high-frequency hiss from Flyer.
This hiss is a normal result of sampling noise inherent in Flyer’s DSP-based servo loop.
Symptom:
Power (+30 VDC) has just been applied to the head, the Pwr LED is green; however, more than 30
seconds has elapsed and the Status indicator is still blinking green at a slow (2 Hz) rate.
Possible Causes:
Flyer’s OS or ash memory is corrupted.
A fault exists that prevents Flyer’s Operating System from booting. This fault condition may be eld re-
pairable. Contact SYNRAD Technical Support for instructions on how to proceed.
Symptom:
Power (+30 VDC) has just been applied to the head, the Pwr LED is green, but the Status indicator is
blinking red at a slow (2 Hz) rate.
Possible Causes:
Flyer is in alternate boot mode because it has failed to fully boot-up ve times in a row.
Allow the alternate boot sequence to continue. If the Status lamp starts blinking red at a fast (10 Hz) rate,
then the alternate boot mode was successful. Contact SYNRAD Technical Support for instructions on
how to proceed.
Symptom:
Power was applied to the head, the Pwr LED is green, however the Status indicator was blinking red at
a slow (2 Hz) rate and is now blinking red at a fast (10 Hz) rate.
Possible Causes:
Flyer’s OS has completed an alternate boot sequence.
A fault exists that prevents Flyer’s Operating System from booting normally. This fault condition may be
eld repairable. Contact SYNRAD Technical Support for instructions on how to proceed.
Symptom:
Flyer booted up normally (Pwr and Status LED’s are solid green) and a mark session was in progress
when the Status indicator began ashing red at a fast (10 Hz) rate and the laser quit ring.
Possible Causes:
Flyer received a ‘start mark’ signal; however, the Fast Acting Safety Interlock (FASI) feature is en-
abled and a high level (5 V–24 VDC) signal was not detected on input IN3.
