Chapter 2 BASIC FUNCTION DESCRIPTION
This chapter describes the controller's front panel layout, user interface and basic operation. When the
user has completed this chapter, he or she should have a basic understanding of the various operating
modes of the unit, and be able to use the keyboard and liquid crystal display (LCD) to navigate through
those modes.
2.1 Front Panel
The front panel (figure 2.1) of the RC2000C contains an ON/OFF switch, a 2 row by 40 column backlit
LCD, and a 4 by 4 matrix keypad with tactile feedback. An AC line circuit breaker is built into the
ON/OFF switch, and a 12-amp circuit breaker (located on the back of the unit) protects the controller's
36-volt actuator drive circuits. When a circuit breaker of this type trips, it will protrude from its mounting
bezel. To reset a circuit breaker, turn the power switch off, wait a few minutes for the circuit breaker to
cool down, then depress the breaker so that it latches and is even with the bezel.

The field in the upper right hand corner of the LCD is reserved for the display of the current mode of the
controller. The various modes are introduced in the following section. If an error condition is active, an
error message will periodically flash across the bottom row of the display. Error messages are
discussed in chapter 7. Chapter 5 explains the contents of every field on the display for all of the
various controller modes.
An examination of the keyboard in figure 2.2 reveals that many of the keys have 2 or more labels. The
function of each key is determined by the current operational mode of the controller. The various
modes are discussed in the following section.
