Functional Description Printed Circuit Boards Printed Circuit Boards The LTQ Orbitrap XL is controlled by a PC running the Xcalibur software suite. The software controls all aspects of the instrument. The main software elements are the communication with the linear ion trap, the control of ion detection, and the control of the Orbitrap mass analyzer. The following pages contain a short overview of the various electronic boards of the LTQ Orbitrap XL. For each board, its respective location and function are given. If applicable, the diagnostic LEDs on the board are described. The electronics of the LTQ Orbitrap XL contains complicated and numerous circuits. Therefore, only qualified and skilled electronics engineers should perform servicing. A Thermo Fisher Scientific Service Engineer should be called if servicing is required. It is further recommended to use Thermo Fisher Scientific spare parts only. When replacing fuses, only use the correct type. Before calling a Service Engineer, please try to localize the defect via errors indicated in the software or diagnostics. A precise description of the defect will ease the repair and reduce the costs. Warning Parts of the printed circuit boards are at high voltage. Opening the electronics cabinet is only allowed for maintenance purposes by qualified personal. ▲ Note Many of the electronic components can be tested by the LTQ Orbitrap XL diagnostics, which is accessible from the Tune Plus window. ▲ 1-30 LTQ Orbitrap XL Hardware Manual Thermo Fisher Scientific
Linear Ion Trap Electronics Functional Description Printed Circuit Boards The linear ion trap is connected to the LTQ Orbitrap XL main power switch. The linear ion trap has a sheet metal back cover. Figure 1-23 shows the electronic connections at the rear side of the linear trap. Cold Ion Gauge Figure 1-23. Electronic connections to linear trap (covers removed) The linear ion trap electronics has two connections with the LTQ Orbitrap XL electronics: • Data communication with the internal computer of the LTQ Orbitrap XL. Refer to the topic “Electronic Boards at the Right Side of the Instrument” on page 1-32. • Signal communication (SPI bus) with supply information for the instrument control board. Refer to the topic “Instrument Control Board” on page 1-37. For further information about the linear ion trap electronics, refer to the LTQ XL Hardware Manual.
