2.10. DIELECTRIC TESTING
Do not perform any high voltage dielectric testing on the transfer switch with the TSC 800
controller connected into the circuit, as serious damage will occur to the controller. All AC
control fuses or control circuit isolation plugs connected to the TSC 800 must be
removed/disconnected if high voltage dielectric testing is performed on the transfer switch.
3. DESCRIPTION
The TSC 800 controller consists of two parts; a Lexan faceplate, which is mounted externally on the
transfer switch door, and a printed circuit board (PCB), which is mounted inside the transfer switch
door.
3.1. LEXAN FACEPLATE
The Lexan faceplate is shown as in FIGURE 7. The Lexan pushbuttons are connected to the
main PCB via plug-in ribbon cable. The main features of the Lexan faceplate are described
as follows with reference to FIGURE 7.
