The PAT DS 350 G Load Moment Indicator Operator’s Handbook is the manual that accompanies the DS 350 G LMI system, the microprocessor-based safety device that monitors crane functions and gives the operator a continuous reading of the machine’s capacity. The handbook has been written for the crane operator first – the person who has to start the system, select the language, confirm the reeving, enter the operating code and read the load moment meter before every lift – but it also carries the service, maintenance and troubleshooting content that keeps the LMI reliable over a long working life.

What This LMI Manual Covers In Practice

The DS 350 G Load Moment Indicator system is built around a central microprocessor unit, an operating console, a length/angle sensor mounted inside the cable reel on the boom, pressure transducers on the lift cylinders, and anti-two-block switches on the boom head. The handbook explains how those parts work together on the reference/real comparison principle: the real value coming from force and pressure measurement is compared against capacity charts, boom weights, centres of gravity and dimensions stored in the processor memory, and when limits are reached the console warns the operator and cuts the dangerous crane movements.

Section 3 of the PAT DS 350 G operator’s handbook describes each console element in detail, including the load moment indicator meter, the language switch, the reeving switch, the anti-two-block warning light, the load moment prewarning light, the load moment alarm light, the load indication button, the INFO button, the angle limit button, the “E” enter button, the by-pass key switch with its three positions, the operating code switch and the main/auxiliary hoist selector. Section 4 walks the operator step by step through the information run – the messages that introduce the console, the load moment meter zones, the reeving setting, the alarm states and the override key warnings – before moving into the programming procedure.

Operating Code, Angle Limits and Machine Configuration

Setting the LMI to match the actual crane configuration is treated as safety-critical throughout the document. The thumb wheel operating code switches must be set to the code printed in the load chart for the current setup, whether that is on outriggers, on rubber or with a jib fitted at a particular offset. The manual explains how the system reacts to a change of code, how to confirm the configuration on the display, and how the outrigger and axle lockout checks are presented to the operator when the corresponding codes are selected.

Angle limits have their own chapter. The DS 350 G stores presets for maximum and minimum boom angle within the crane geometry, and the operator can activate one or both limits, set new values by moving the boom to the intended position and confirming with the enter button, or clear the limits by pressing the angle limit and enter buttons together. Every step of the procedure is shown with the message text the console will display, so the manual doubles as a screen-by-screen reference during a lift setup.

Troubleshooting and Error Codes

The troubleshooting chapter of the PAT DS 350 G Load Moment Indicator operator’s handbook lists the E01 to E06 error codes together with their causes and the action required. E01 and E02 cover radius and angle range exceedances caused by raising or lowering the boom too far. E03 flags a boom position outside the permissible working area. E04 covers an operating mode that does not exist for the current configuration. E05 relates to a prohibited length range or a length sensor cable that has slipped off the drum. E06 covers the luffing fly jib angle or radius range. Operating errors that the crane operator can clear are separated from faults that require factory-trained service personnel.

Pre-Operation Inspection, Service and Multilingual Sections

Before each shift, the operator is taken through the electrical connection checks for machines with a main hoist only and for machines with main and auxiliary hoists, including the correct positioning of the anti-two-block switch weight, the bypass plug, and the connecting cable when a jib or boom extension is fitted. The inspection then requires a functional test of the anti-two-block alarm light and audible alarm by manually lifting the switch weight, a slow raise of the hook block into the weight, and a slow lowering or telescoping to create a potential two-block condition, verifying that the alarm sounds and the movement stops. The service and maintenance section covers cabling, length sensor cable insulation and guides, anti-two-block switch freedom of movement, cable reel tension, and pressure transducer and hose oil leakage.

The complete PAT DS 350 G LMI manual is repeated in four full language sections – English, Spanish (Manual de Servicio del Indicador del Momento de Carga PAT DS 350 G), French (Mode d’emploi Controleur d’etat de charge PAT DS 350 G) and German (Bedienungshandbuch PAT Lastmomentbegrenzung DS 350 G) – so the same content can be handed to an operator or technician working in any of the four languages.

Why This PAT DS 350 G Operator’s Handbook Matters

The DS 350 G is a crane safety device, and the way it is set up directly affects what the machine will and will not do. A wrong operating code, an incorrect reeving setting, an unconfirmed outrigger setup or a misread error code can put a lift outside the configuration the load chart was written for. This handbook gives the exact console text, the exact button sequence and the exact error descriptions, so the operator can set the system correctly, recognise a warning state, and act on it without guesswork. The same content supports the technician doing pre-operation inspections, checking anti-two-block switches, tracing a length sensor fault or investigating an E-code the operator cannot clear.
