Alternative Models & Compatibility
When transitioning from legacy CP32xx or CP39xx series, note that the CP3718-0020 utilizes an integrated mounting arm adapter layout that directly aligns with Rittal and Rolec systems. Software compatibility requires proper runtime licensing in TwinCAT 3; depending on the chosen CPU variant (E3930 vs. E3940), the controller level maps to performance classes TC3:40 or TC3:50. Ensure projects are targeted correctly in TwinCAT XAE before deploying runtime tasks.
Application Pitfalls & Engineering Notes
While the CP3718-0020 features internal fans to achieve uniform heat distribution across its aluminum housing, it relies entirely on passive radiation for cooling. You must maintain at least 20 cm (7.9 inches) of open clearance around the entire exterior of the unit. Placing the device in tight corners, alcoves, or directly against structural bulkheads will impede convective airflow, causing thermal throttling of the Intel Atom processor under peak graphic or logic execution cycles.
Commissioning & Wiring Tips
To retain the IP65 rating, only utilize industrial-grade push-pull RJ45 patch cables designed for IP65 environments. Ensure that the sealing rings on unused interface ports are fully engaged and torqued down. Ground the mounting arm assembly directly to the machine frame using high-frequency copper ground braids. Poor high-frequency grounding can introduce electrical noise into the capacitive multi-touch controller, resulting in erratic coordinate tracking or phantom touch signals.
Installation Guidelines
CRITICAL WARNING
Before starting any installation, modification, or wiring adjustments, ensure all power sources to the machine arm and internal PC modules are completely de-energized. Confirm that internal UPS capacitors (if fitted) are fully discharged to prevent high-energy transients or system damage during component handling.
1
Mount the CP3718-0020 onto the 48 mm mounting arm tube (Rittal/Rolec standard). Adjust the tilt and rotation adapters to the desired operational angle before tightening the locking collar bolts to the OEM-specified torque.
2
Route the power supply line (24 V DC) and Ethernet patch cables through the center of the mounting tube to avoid cable tension or binding during screen rotation.
3
Connect the IP65 push-pull Ethernet interface and securely terminate the 24 V DC input terminal. Seal any unused ports with the provided IP65 rated blanks.
4
Turn on the primary 24 V DC supply and verify that the display powers up, initiates POST, and boots into the configuration console or operating system successfully.
