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 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.
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
(horizontal 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 I/O control board to perform diagnostics on sensors.
