Section 7 7.7 Circuit Board Identification

There are two main circuit boards in the sampler; the Utility Board and the CPU board. The CPU board is attached to the bottom panel and the Utility board is located inside the control housing behind the motor/gearbox assembly.

Note: Removal and handling of the circuit boards used in the sampler requires knowledge of ESD (Electro-Static Discharge) precautions and the CMOS (Complementary Metal-Oxide Semiconductor) circuit components used in the sampler. Static electricity has the potential to damage the CMOS components of the sampler when the boards are unplugged and removed from the case. Precautions must be taken to assure static-free personnel and work area prior to handling the circuit boards.
