• Power Supply: Connect a stable 24VDC power source to the DC 24V terminals. Observe polarity (+ and -).
• DC Inputs (I1-I8): Connect your digital input devices (e.g., switches, proximity sensors) to these terminals.
• Analog Inputs (A1, A2): These inputs accept 0-10V analog signals from sensors (e.g., temperature, pressure).
• Relay Outputs (Q1-Q4): Connect the devices you wish to control (e.g., motors, lights, valves) to these relay contacts. Each relay can switch up to 10A at 250V.

5. Software Installation & Programming

The Electrodepot 93EL6DR can be programmed directly via its HMI and keypad or through PC software using a USB connection.

5.1. PC Software Programming (Ladder Logic)

Install the provided programming software on your computer. This software allows you to create and edit ladder logic programs, simulate their operation, and then upload them to the PLC via the USB interface.

6. Operation

Once programmed, the PLC will execute the loaded logic. The HMI display provides status information, and the keypad can be used for basic monitoring, parameter adjustments, or manual control depending on the program.

• Monitoring: Use the display to view input/output status, timer/counter values, and program execution.
• Keypad Navigation: Use the arrow keys to navigate menus and the OK/ESC buttons for selection and exit.
• Program Execution: The PLC operates continuously once powered and a program is loaded.

7. Applications

The Electrodepot 93EL6DR is suitable for a wide range of automation tasks, from simple control sequences to more complex industrial processes.

Common applications include:

• Industrial process control (e.g., packing, conveyors, transportation)
• Home automation systems
• Security systems
• Lighting and climate control

8. Maintenance

Regular maintenance helps ensure the longevity and reliable operation of your PLC controller.

• Cleaning: Keep the unit free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
• Connections: Periodically check all wiring connections for tightness and signs of corrosion.
• Environment: Ensure the operating environment remains within specified temperature and humidity ranges.

9. Troubleshooting

If you encounter issues with your Electrodepot 93EL6DR, consider the following common troubleshooting steps:

• No Power: Verify the 24VDC power supply is connected correctly and is active. Check fuses if applicable.
• Inputs Not Responding: Check wiring to input devices. Ensure input signals are within the specified voltage range. Verify the program logic for input handling.
• Outputs Not Activating: Check wiring to output devices. Ensure external devices are powered. Verify the program logic for output control.
• Communication Issues (PC): Ensure USB drivers are correctly installed. Check USB cable connection.
• Incorrect Program Behavior: Review your ladder logic program for errors. Use the simulation feature in the PC software to debug.
