Final Inspection
A. Voltage at terminal posts 4 and 5- should be no less than 9 volts DC and no more than 36 volts
DC.
B. Check for possible grounds.
C. Check voltage and current during operation.
The voltage on terminals 4 & 5 should never drop below 11 volts during the gate up cycle.
The gate up current at the mechanism should be 6-15 amps (longer arms require more current).
Power down current should be 6-15 amps.
D. Check ascending and descending times.
Validate ascend and descend times with the values that were programmed during the installation.
Measured times should be within 1 second of the programmed times. This can be verified by using
a stop-watch or the timer on a mobile device.
E. Brake air gap - using Air Gap Tools (part numbers NYK:074070-C and NYK:074070-D), verify air
gap is no less than 0.015", and no more than 0.020".
