Identifying Faults and Troubleshooting
Indication
Probable Cause
Suggested Solution
AfiPass II COMM
FAULT LED blinks red
& AfiControl displays
communication fault
with the devices.
Broken
communication
between AfiPass II
and PC.
Verify the communication cables between the
AfiPass II & PC are intact.
Make sure the AfiPass II communication connectivity
is intact, properly connected and wired according to
spec.
Make sure the AfiPass II is not in Test Mode.
No LED and/or
display indication in
the AfiPass II.
Display PCB flat
cable is
disconnected.
AfiPass is not
working at all.
Verify that the flat cable leading from the control
PCB to the display PCB is intact and properly
connected.
Verify that the 24VAC power cable is connected
properly to the AfiPass II.
Verify that the 24VAC power supply is turned ON
and supplies 24VAC.
If power is OK, replace controller.
ID tag not identified/
insufficient ID range
Antenna not
calibrated/low
transmission power.
Initiate antenna calibration process and adjust Tx
power level.
Display shows 'ERR
06' and/or 'ERR 08'
Antenna is shorted
or disconnected.
Antenna has not
been calibrated to
resonance.
Verify the antenna cable is intact, properly
connected, and no loose wires from the shield wire
of the coax cable are shorted.
Initiate antenna calibration process and adjust Tx
power level.
If error persists: Isolate the problematic component
(i.e. antenna output or the antenna itself) by
crossing the malfunctioning antenna with a
functioning antenna connected to same controller
and initiating antenna calibration process on both
outputs. If the malfunctioning antenna still shows an
error replace antenna. Otherwise replace controller.
Display shows 'ERR
05'
Antenna Tx power
level is too high.
Transmission
circuitry
overcurrent/
overtemperature.
Initiate antenna calibration process and adjust Tx
power level.
If error persists, replace controller
.
