The electrical section explains the ECOS (Electronic Crane Operating System) and its CAN-Bus based control architecture. It covers the joystick modules, joystick axis functions, direction and safety-zero contacts, ECOS control principles, electrical installation panel, relay installation and resistor boards. The manual also explains how the resistor boards continuously monitor switched circuits and how electrical faults can be detected through the ECOS system.
Detailed information is provided for the telescope cylinder proximity switch system, including switch sequences, locking and unlocking functions, trigger plates and switch status. The proximity switch table identifies switches such as S2110N through S2118N and S3702N through S3710N and explains their associated ECOS or EKS 4 functions.
The hydraulic section provides an in-depth overview of the GMK 5100 superstructure hydraulic system. It covers the variable-displacement main pump P1, the dedicated slewing pump P2, load-sensing operation, the main control block, proportional control solenoids, pressure compensators and relief valves. The manual describes how the load-independent hydraulic control system allows multiple crane functions to operate while maintaining proportional flow distribution.
Dedicated sections cover the main hoist, auxiliary hoist, telescope cylinder, boom derrick cylinder and slewing system. The telescope section is particularly detailed, showing the hydraulic flow paths for unlocking boom section pins, extending boom sections, locking boom section pins, unlocking telescope cylinder pins, retracting the unlocked cylinder and locking the cylinder pins.
The manual also documents auxiliary hydraulic functions including counterweight control, turntable pinning, cab tilt and swingaway lattice (PTJ) control. Component diagrams identify solenoid valves, pressure switches, holding valves, relief valves, pressure transducers and other important hydraulic components.
The final section covers hydraulic filtration and cooling, including the main reservoir return filter, pilot pressure filter, breather, contamination warning switches, thermostatic switches and hydraulic oil coolers. These diagrams and descriptions make the manual useful as a technical reference when diagnosing system operation or understanding component relationships.
