red lion KADET 2 G307K2

The Red Lion G307K2 Kadet 2 Operator Interface is a 7-inch TFT display designed for monitoring and controlling multiple devices in industrial applications. It serves as a versatile solution for operators needing to interact with various systems, including PLCs, motor drives, and bar code scanners.

Function Description

The G307K2 acts as a multi-protocol converter, facilitating communication between dissimilar Ethernet-based products. It is equipped with three high-speed serial communication ports (one RS-232 and two RS-232/422/485 ports) and a 10 Base-T Ethernet port. The Ethernet port supports up to four protocols simultaneously, enabling broad compatibility. The unit's configuration is stored in non-volatile Flash memory, ensuring data retention even without power.

Important Technical Specifications

Certifications and Compliances: UL Listed (File #E302106, UL508), UL Type 4 Indoor Use Only Enclosure rating (Face only), UL50, IP65 Enclosure rating (Face only), IEC 529.
Construction: Plastic enclosure with a NEMA 4/IP65 front panel when properly installed.
Weight: 30 oz. (850 g).

Usage Features

Ease of Programming: Programmed with Red Lion's free Crimson 3 software, which simplifies communication configuration and screen design through a drag-and-drop interface and an embedded image library.
Field Configuration Loading: The SD card slot allows for easy loading of configuration files in the field, facilitating updates and transfers.
Multi-Device Connectivity: With its multiple serial and Ethernet ports, the G307K2 can connect to and manage a wide array of industrial devices simultaneously.
Front Panel Indicators: Three front panel LED indicators provide visual feedback on the unit's status:
- RED (COM) flashing indicates communications are active.
- GREEN (CPU) steady indicates the CPU is functioning.
- ORANGE (PWR) steady indicates power is applied.
Touchscreen Operation: The resistive analog touchscreen provides user input, producing an audible tone (beep) when an active cell is touched. It is fully functional upon initialization and can be operated with gloved hands.
Mounting: Designed for panel mounting into enclosures with a depth of 4". It requires 1" clearance around the sides for mounting hardware and 2.5" along the bottom edge if using Red Lion communication cables.
Switch Settings: Includes switches for normal mode operation and for displaying the Clear Database prompt, allowing users to clear the database or continue in normal mode. Switch 4 must remain in the ON position at all times.

Maintenance Features

Battery Replacement: The unit uses one CR2032 coin-type lithium battery to maintain the Real-Time Clock (RTC) and for proper Ethernet download operation. To replace the battery, power and cabling must be removed, the rear cover detached, the old battery replaced with a new one, and then the unit reassembled. Used batteries must be disposed of according to local waste regulations.
Troubleshooting: Requires Crimson 3 Software build 619.004 or later for programming. Users converting existing databases from original Kadet models should be aware of potential wiring differences and programming port availability issues, with Red Lion providing Tech Notes on their website for assistance. Technical support is available via phone, fax, and email.
Safety Precautions: Users are advised to observe all safety regulations, local codes, and instructions. The unit should not be used to directly command motors, valves, or other actuators without safeguards. When handling the operator interface without the rear cover, static charges should be discharged by touching a grounded bare metal object. The circuit board contains static-sensitive components, and care should be taken to avoid touching surface areas to prevent contamination.
