This section describes the installation of an additional channel (sensor board) in a DECADE Elite using the DECADE Elite additional channel kit (p/n 175.0210). This kit enable you to upgrade your DECADE Elite to an instrument with two or three flow cells.
Therefore, always disconnect the instrument from all power sources before disassembly. In the next sections all steps are explained in detail to guide you through the installation procedure. In case of questions please contact Antec, the Netherlands for assistance.
Sensor board installation 1. Removing the rear panel To be able to access the electronic parts in the DECADE Elite the rear panel has to be removed. All circuit boards are mounted on a separate metal frame, which is fixed on the rear panel of the detector. To access the electronic parts loosen the four M3 Phillips screws as depicted in the figure below using a Phillips PH-1 screw driver.
175.0020 - DECADE Elite service manual - rev 03 Figure 7 Detector with rear panel pulled backwards and frame with elec- tronic boards accessible. The rear panel is constrained by the length of the connected cables. The PCB frame can rest on the casing of the power supply compartment with- out any problem (as depicted in the figure above).
