****THIS BOARD REQUIRED FOR YOU TO HAVE SAFETY SENSORS ****
***REPLACES OLD 500415 AND 500410 CONTROL BOARD, BUT REQUIRES TO ADD PART NUMBER 550011***
The Sentry 500022 Control Board is a
genuine OEM replacement main logic board designed specifically for the Sentry
300 series vehicular swing gate operators. As the central
"brain" of the system, this board manages all motor functions, power
distribution, and safety monitoring to ensure your gate operates with precision
and security.
Core Functionality
- Plug-and-Play
Logic: Engineered for a direct "drop-in"
replacement, featuring standardized terminal blocks that match the
original wiring harness of the Sentry 300 system.
- Solar-Optimized
Performance: Specifically designed for
high-efficiency power management, making it the industry standard for
solar-powered gate sites while remaining fully compatible with traditional
AC-charged systems.
- Advanced
Safety Monitoring: Equipped with dedicated inputs
for monitored safety devices (such as photo eyes or sensing edges),
ensuring the gate reverses or stops instantly if an obstruction is
detected during travel.
- Precision
Motor Control: Regulates the 12V DC motor's torque
and speed, providing a reliable "Stall Force" sensitivity
adjustment to protect pedestrians and vehicles.
Technical Specifications
- Part
Number: 500022
- Voltage:
12V DC system.
- Charging
Circuit: Integrated smart charging logic
designed to maintain lead-acid or AGM batteries via solar panels or an AC
transformer.
- Diagnostic
Interface: Features onboard LED indicators
that provide real-time feedback for troubleshooting battery health, limit
switch triggers, and accessory signal inputs.
- Adjustability:
Includes user-accessible potentiometers for fine-tuning the auto-close
timer and obstruction sensitivity.
Compatibility
This control board is the factory-specified
replacement for:
- Sentry
300 Single Swing Gate Operators.
- Sentry
302 Dual Swing Gate Operators (manages both
Master and Slave arms).
- Note:
This board is designed for UL 325 compliant systems;
ensure your safety accessories are correctly wired to the monitored
terminals to maintain full system functionality.
Installation Note
When replacing the 500022 board, it is critical to
disconnect both the battery and the solar panel (or transformer) to
prevent electrical shorts. Once the new board is mounted, you must perform
the "Learn" procedure to set the gate's open and
close limits. It is highly recommended to test the battery's voltage during
installation, as a weak battery is the leading cause of intermittent logic
errors.
