Quick Gate Sensor Check
-
Locate the safety sensor and reflector.
-
Run your hand in front of the sensor. Listen for a clicking sound.
-
If the sensor clicks: The sensor is detecting properly, but there may be another issue with the gate. At this point, a service technician may need to come out and diagnose the problem.
-
If the sensor does not click: The sensor may be out of alignment, the beam may be blocked, or the sensor/reflector may be dirty.
-
Clean the sensor and reflector. Wipe away dirt, dust, moisture, or condensation, then test it again.
-
Check the alignment. Make sure the sensor or reflector hasn't been accidentally bumped or moved. Carefully adjust the alignment and test it by running your hand through the beam again.
-
Listen for the click. Once properly aligned, the sensor should click when your hand breaks the beam.
Good luck! This simple check may solve the problem and save you the cost of an unnecessary service call.
Safety Tip: Never stand in the gate's path while testing it, and don't attempt to bypass or disable any safety device.
Batteries
All gate operators, except Amazon units, are battery-operated. The batteries typically have an expected life of 2–3 years, depending on operating conditions.
Both extreme heat and cold can shorten battery life. As batteries begin to weaken, low voltage can cause the gate operator to malfunction and may potentially affect sensitive electronic components.
Best Practice: Have your gate operator inspected and serviced once a year. During the service, the technician should check the batteries, charging system, voltage, safety devices, and overall operation.
A little preventive maintenance can help avoid unexpected breakdowns, protect your equipment, and extend the life of your gate operator.
All of our service vehicles carry a full stock of replacement batteries, helping us get your gate operator back up and running as quickly as possible.
Our goal is to minimize downtime. In many cases, if a weak or failed battery is the problem, our technicians have the correct replacement on the truck and can take care of it during the service call—no waiting for parts and no unnecessary delays.
