Troubleshooting
Symptom
Possible Cause
Solution
Unit will not turn
on
No power
Make sure that there is power to the turnstile power terminal block. Check if LEDs are
lit on the I/O control board and the seven-segment display is showing a number.
Blown fuse
Check fuse. If necessary replace with a
2.5A (slo-blo) fuse.
Constant auditory
alarming
Communication/
Low-voltage cable
Check the I/O control board to see if amber LEDs are lit. If they are lit, the most likely
problem is a loose or improper communication connection. Disconnect the black 16-
pin connectors from the I/O control board and motor controller boards, apply contact
cleaner / lubricant to connector pins and reseat. Retry operation.
If condition persists, perform the same process on the 16-pin connectors going into and
out of the light boards and sensor boards. Retry operation. Alvarado Technical Support
has a process document and can provide additional instructions.
Barrier arms
operate erratically
Barrier arms do
not move.
Digital position
encoder is not in
place
Verify the digital position encoder is secured to the pully shaft with all the locks tabs in
place. [Figure 30].
NOTE: After re-seating the digital position encoder, the barrier
Home position must be reset PRIOR to power cycling the turnstile.
Blown 24VDC
fuse on the motor
controller board.
Locate the motor controller board fuses [Figure 31]. Using a multimeter, check the
24VDC 6.3A fuse for continuity. If the fuse is blown, contact Alvarado for replacement
instructions.
Blocked Sensor
auditory alarms
sounds after 15
seconds (default).
Wire or cable
blocking sensors
Check for a stray wire or cable in front of the transmit and receive operational sensors
(horiazontal arrays).Tuck any stray wire or cable out of sensor viewing area. If this does
not resolve the problem, contact Alvarado technical support for instructions on using
the ADR-UP and ADR-DN buttons on the I/O control board to perform diagnostics on
sensors.
Barrier arms do
not align in closed
position
Home position
needs to be reset
Follow the Setting the Home Position instructions in Appendix A on Page 32.
System does not
boot.
Motor controller
board fuse is
blown.
Locate the motor controller board fuses [Figure 31]. Using a multimeter, check the
5VDC 3A and 12VDC 2A fuses for continuity. If a fuse is blown, contact Alvarado for a
replacement.
NOTES: If a user status display or open / closed status light is out,
this may indicate the 5VDC 3A fuse is blown. If the motor controller board LEDs
are out, this indicates the 12VDC 2A fuse is blown.
