- Mains Inputs: Connect for mains voltage monitoring in AMF/ATS applications.
- Control Outputs: Connect to engine start/stop solenoids, fuel solenoids, circuit breakers, and other control devices.
- Communication Ports: USB for PC connection, RS-485, Ethernet, and GPRS via optional plug-in modules.
5. Operating Instructions
5.1 Basic Operation
Once properly installed and powered, the D-500-LITE-MK2 will display its operational status on its LCD or LED screen. Navigation through menus and settings is typically done using the front panel buttons.
- Power On: The controller will perform a self-test and display the main screen.
- Menu Navigation: Use the UP/DOWN arrow buttons to scroll through parameters and menus.
- Selection/Confirmation: Use the ENTER button to select an option or confirm a setting.
- Exit/Back: Use the ESCAPE button to go back to the previous menu or exit a setting.
5.2 Operating Modes
The D-500-LITE-MK2 supports various operating modes, configurable through the controller's menu or PC software:
- Manual Mode: Allows direct manual control of the generator start/stop sequence.
- Automatic Mode (AMF/ATS): The controller continuously monitors the mains power supply. In case of a mains failure, it automatically starts the generator, transfers the load, and reverses the process upon mains return.
- Remote Start Mode: The generator can be started and stopped via a remote signal, often used in conjunction with building management systems or external timers.
- Test Mode: Allows for testing the generator's operation without transferring the load or under load conditions.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your D-500-LITE-MK2 controller and the associated generator system.
- Periodic Inspection: Visually inspect the controller and its wiring for any signs of damage, loose connections, or corrosion.
- Cleaning: Keep the controller's display and buttons clean using a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Firmware Updates: Periodically check the Datakom website for available firmware updates. Updates can be performed via the USB port using the provided PC software.
- Battery Check: Ensure the generator's starting battery is in good condition, as it powers the controller during startup.
