NORMAL OPERATION
Normal operation occurs when communication has been established
between all the components within the Type SLC controller and
everything is operating properly. During normal operation:
1. The set point, process variable and control output will appear on
the front panel display.
2. The controller operates as a basic (single or dual loop PID), cas-
cade or ratio station, depending upon the configuration entered.
POWER UP
Power up the unit. When the controller is first powered up, the follow-
ing screen appears for a short time and then the process display
screen appears if a configuration is entered. If no configuration is
entered, the main menu screen appears.
During start-up, the controller is performing some self-diagnostics. If
one of the tests fails, a message will appear. Refer to
