The iLEARN System Manual describes a comprehensive door control system designed for freight elevator applications, featuring various components for door and gate operation, control, and diagnostics. The system is engineered to provide reliable and efficient control over hoistway doors and car gates, with a focus on safety, adjustability, and troubleshooting capabilities.

Function Description:

The iLEARN System is a next-generation freight door system that integrates door control, VFD floor control, and VFD gate control. Its primary function is to manage the opening and closing of hoistway doors and car gates, ensuring synchronized and safe operation. The system utilizes a CANbus network for communication between its components, allowing for centralized control and diagnostics. It supports both "Q" and "PA" style interlocks, adapting to different installation requirements. The iLEARN Door Control acts as the central hub, processing commands from the elevator control and managing the iDRIVE VFD Floor and Gate Controls.

Important Technical Specifications:

Power Requirements: The iLEARN Door Control requires 110 VAC, while the iDRIVE VFD Floor Control requires 240 VAC hoistway power. Machine room power requirements specify a 110VAC power supply for the iLEARN Door Control and a 240 VAC 3-Phase power supply for COURION's Hoistway Equipment. A disconnect switch with three (3) 15 AMP fuses should be provided by the General Contractor in the Machine Room. The system can also be powered by 260VAC, with COURION supplying two (2) single-phase step down transformers.
Wiring Bundles (iWIRE Package):
- Motor Wiring Bundle (#90-947400): Four (4) wire hoistway motor cable for COURION Door Motors, Gate Drives, and Retiring Cam Motors to iDRIVE VFD Controls.
- CANbus Cable (#90-947405): Two (2) twisted pair communication wires and a drain wire for iLEARN Door Control to all iDRIVE VFD Floor and Gate Controls.
- Hoistway Cable (#90-947409): Five (5) shielded 16 AWG insulated power wires, one (1) yellow 18 AWG insulated wire for CANbus Address In/Address Out Input, and three (3) black 18 AWG insulated spare wires.
- Floor/Gate Wiring Bundle (#90-947415): Fifteen (15) 18 AWG insulated wires for Door Push Buttons, EUDs, and Floor Zone Switches to iDRIVE VFD Controls.
- Traveling Cable (#90-947416): Four (4) twisted pair shielded serial CANbus communication wires, five (5) 16 AWG insulated power wires, and three (3) 18 AWG insulated spare wires.
- Interconnection Wiring Bundle (#90-947423): Three (3) 16 AWG insulated power wires and twenty (20) 18 AWG insulated wires for iLEARN Door Control to Elevator Control interface.

Maintenance Features:

LED Indicators:
- iDRIVE Network LEDs (RX & TX): Rapidly flashing indicates normal communication; steady or dim flashing indicates a communication error.
- STATUS LED (iLEARN Door Control): 1 flash/sec for normal operation; other flash patterns indicate specific faults (iDRIVE fault, memory failure, CAN controller failure).
- +5V & +24V LEDs: Constantly ON indicates proper power for CANbus and digital inputs.
- CONTROLLER STATUS LED (iDRIVE VFD Floor Control): 1 flash/sec for normal operation; other flash patterns indicate specific faults (door operation fault, motor fault, memory failure, production test mode).
