2. DESCRIPTION
The TSC 80e controller utilizes microprocessor-based design technology, which provides high
accuracy for all voltage sensing and timing functions. The TSC 80e is factory configured to control all
the operational functions and display features of the automatic transfer switch.
The TSC 80e 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 on
the enclosure door. The TSC 80e PCB contains a built-in LCD display that is visible from the front
panel faceplate. The Lexan faceplate contains operation/data-acquisition/programming pushbuttons
and indication LEDs.
2.1. LEXAN FACEPLATE
The TSC 80e Controller Lexan faceplate is shown as in FIGURE 1. The Lexan pushbuttons
and LED lights 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 1.
