The side panel reveals detailed terminal wiring diagrams, including connections for RS485 communication, various input/output terminals labeled 'NIC' (Not In Use/Connected), and specific terminals for relay and SSR outputs, alongside power input details.
4. Setup and Installation
4.1 Mounting
The X3-3107-0000 controller is designed for 1/8DIN panel mounting (48x96mm cutout). Ensure sufficient space for ventilation and wiring connections at the rear.
- Cut a panel opening of 45mm x 92mm (H x W).
- Insert the controller into the opening from the front.
- Secure the controller using the provided mounting brackets from the rear.
4.2 Wiring
Refer to the wiring diagram on the side of the controller and the detailed instructions below. Use appropriate wire gauges for all connections.
- Power Supply: Connect 100-240VAC to the designated power terminals. Observe correct polarity if applicable.
- Inputs: Connect process inputs (e.g., sensors) to the specified input terminals.
- Analogue Output: Connect to the analogue output terminals for proportional control signals.
- Relay Outputs: Connect control loads to the relay output terminals. Note the contact ratings.
- SSR Outputs: Connect solid state relay loads to the SSR output terminals.
- RS485 Communication: Connect RS485 communication lines (A, B, GND) to the corresponding terminals for data exchange with other devices.
5. Operating Instructions
5.1 Power On
After verifying all wiring, apply power to the controller. The display will illuminate, showing the current process value and potentially the setpoint.
5.2 Front Panel Controls
- Display: Shows process values, setpoints, and menu parameters.
- A/M Button: Toggles between Automatic and Manual control modes.
- Arrow Keys (Up/Down): Used to navigate menus and adjust parameter values.
- Function/Enter Key (*): Confirms selections and enters menu levels.
- Escape/Back Key (↵): Exits menus or cancels changes.
5.3 Basic Operation
- Viewing Setpoint: Press the Up or Down arrow key briefly to display the current setpoint.
- Adjusting Setpoint: While the setpoint is displayed, use the Up/Down arrow keys to change its value. Press the Function/Enter key to confirm.
- Accessing Menus: Press and hold the Function/Enter key for a few seconds to enter the parameter menu. Use arrow keys to navigate and the Function/Enter key to select.
6. Maintenance
The ASCON X3-3107-0000 controller is designed for minimal maintenance. Regular inspection and cleaning are recommended.
- Cleaning: Gently wipe the front panel with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the device.
- Inspection: Periodically check wiring connections for tightness and signs of corrosion. Ensure proper ventilation around the unit.
- Firmware: Firmware updates, if available, should only be performed by authorized service personnel.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not power on. | No power supply or incorrect wiring. | Check power connections (100-240VAC) and ensure power is supplied. |
| Display shows 'Err' or error code. | Sensor fault, input range error, or internal malfunction. | Refer to the specific error code in the full technical manual. Check sensor wiring and calibration. |
| Output not responding. | Incorrect parameter settings, wiring issue, or load problem. | Verify output wiring. Check control mode (Auto/Manual) and setpoint. Inspect the connected load. |
