SYNC Error
The SYNC signal has occurred before expected.
Possible causes:
• A bad SYNC signal has caused extra SYNC pulses - check voltage
levels with a scope.
• A bad REF signal has caused missing REF pulses - check voltage
levels with a scope.
• Bad REF / SYNC alignment.
• Incorrect
Setup
No SYNC
Two or more consecutive SYNC pulses are missing.
Possible causes:
• No SYNC signal - check the wiring and SYNC sensor voltage levels
with a scope.
• A bad REF signal has caused many extra pulses - check voltage
levels with a scope.
• Incorrect
Setup
Multiple REF / SYNC Errors
Multiple REF / SYNC errors may occur. Often the first error to occur is
the correct error.
Multiple errors may also occur due to incorrect Setup.
