Description
🌐 Product Overview
The Beijer 06020C (Exter K70) is an industrial-grade, keypad-operated human-machine interface (HMI) panel designed for complex machine control and harsh operational environments. Featuring a rugged physical key layout combined with a high-contrast graphical display, this terminal provides operators with tactile feedback and reliable system visualization. Engineered to bridge the gap between heavy industrial equipment and complex automation systems, the Exter K70 stands out for its robust fieldbus compatibility and exceptional mechanical durability.

- Outdoor and Harsh Processing: Water treatment stations and chemical dosing systems where touchscreen performance can be compromised by moisture or debris.
📖 Product Instructions
- Panel Mounting: Prepare a panel cutout matching the specified unit dimensions. Insert the K70 from the front and secure it using the rear mounting brackets, ensuring the sealing gasket is evenly compressed to maintain its environmental protection rating.
- Power Connection: Terminate a stable 24V DC source into the 3-pin power connector block. Ensure the functional ground pin is independently connected to the central cabinet grounding busbar.
- Project Downloading: Connect a PC to the panel using the Ethernet port or a dedicated serial crossover cable. Use the proprietary configuration software tool to compile and deploy your customized HMI screens, alarm configurations, and tag maps.
✅ Initial Startup Checklist
- Verify the 24V DC power supply polarity is correct before applying power to the terminal.
- Confirm that the communication cables (Ethernet/Serial) are securely locked into their respective ports and isolated from high-voltage motor cables.
- Apply power and watch the display screen cycle through the self-test bootloader screen without displaying memory allocation faults.
- Test individual function keys on the boot interface to verify the backlighting and physical feedback mechanisms are operating normally.
🛠️ Maintenance & Care
- Membrane Care: Clean the front overlay panel with a soft cloth dampened with mild soap and water. Never apply concentrated industrial solvents, alcohol, or pressurized steam washers directly to the keypad.
- Gasket Inspection: Check the condition of the rear panel sealing gasket every two years for signs of cracking or compression set to prevent water ingress into the control cabinet.
- Backup Battery: Periodically monitor the health of the internal real-time clock (RTC) battery and replace it during scheduled downtime if low-voltage indicators appear in the system logs.
⚠️ Safety Precautions
- Explosion Hazard: Do not connect or disconnect any communication, power, or auxiliary cables while the circuit is live or unless the area is known to be non-hazardous.
- Correct Installation Voltage: Operating the unit above the 32V DC threshold can result in permanent catastrophic failure of the internal DC-DC converter circuitry.
- Sharp Objects: Instruct operators never to actuate the membrane keys with sharp tools, screwdrivers, or pens, as punctures will compromise the front panel seal and ruin the internal circuitry.
🔍 Troubleshooting & FAQ
- Q: The display stays dark but the status LEDs at the back of the panel indicate power is present. What should be done?
- A: This usually points to a sleep-mode setting or a failure of the display backlight circuit. Try uploading a default blank configuration or power-cycling the device. If the problem persists, the internal CCFL/LED inverter board may require servicing.
- Q: The panel is failing to establish communication with the connected PLC.
- A: Double-check that the communication driver settings, station ID, baud rate, and parity bits in the HMI project match the physical PLC communication configuration exactly. Also, verify that the serial pinout or Ethernet cable layout matches the manufacturer’s specified wiring diagram.
- Q: How can I access the system configuration menu to change IP settings directly on the panel?
- A: During the panel power-up sequence, press and hold a specific combination of function keys (typically F1 and F6 or a dedicated menu button depending on firmware version) to bypass project execution and enter the built-in system service mode.
