Maximum Controls gate operators make service calls easy via the unique
USB port/Black Box On-Board Diagnostics (OBD) feature.
Our gate operators use non-volatile memory to continuously log performance characteristics and
input/output events. A service technician can access this data via a USB port to download the
event history, quickly diagnosing complex or intermittent problems that have been very difficult to
isolate and repair in the past.

< A thumb drive plugged into the USB,
with all history downloaded,
acts as a “Black Box”
to find out what happened. >

The event history is stored
as a .TXT document which can be emailed to the factory for on-site diagnosis. The .TXT file is a log of the most recent 1000 events reported by each module to the central logger. >
