Page 13: Selection Of Lifting Capacity Chart
Selection of lifting capacity chart Selection of lifting capacity tables The system selects the correct lifting capacity according to the operating mode set on the central unit and current boom configuration (length, telescope status, boom length). Calculation of the radius The radius is calculated from the boom length and angle as well as from the boom load derived from the hydraulic pressure measured in the derricking cylinder, taking the deflection of the boom Into consideration.
Page 14: Data Translation And Transmission
Data Translation and Transmission The measured values are digitized in the Data Transmitters, converted into signals and transmitted time- delayed as impressed current via the common dual-line data bus to the central unit. Transmitter Boards All transmitter Boards fitted on a machine are the same part number. The system each board is monitoring is identified to the CPU by the number and configuration of Links (Jumper wires). ...
Page 15: Checking Data Transmitters
Between 0 - 3 links (inclusive) can be fitted to each board. This will give up to 8 Permutations of configuration. Each configuration, varies the 'Output Signal' level of the transmitter board onto the Data Bus, thereby giving it a unique signature, therefore we can have up to 8 transmitters with different output signals on 1 Data Bus.
