General Information 1 GENERAL INFORMATION The PAT Load Moment Indicator (LMI) DS 350 has been designed to provide the crane operator with the essential information required to operate the machine within its design parameters. Using different sensing devices, the Load Moment Indicator monitors various crane functions and provides the operator with a continuous reading of the crane’s capacity.
DS 350 / 1319 3 SYSTEM DESCRIPTION The PAT Load Moment Indicator DS 350 consists of a central micro processor unit, operating console, length/angle sensor, pressure transducers, and anti-two block switches. The system operates on the principle of reference/real comparison. The real value, resulting from the pressure measurement is compared with the reference data, stored in the central processor memory and evaluated in the micro processor.
If any of the displays reflects a deviation between displayed and actual values, an authorized PAT service representative shall be called for repair of the system or reverification of the crane’s LMI calibration.
