Figure 10 Typical Operator Control Panel (Showing the Monitor/Mimic Display Screen)
2.2 Operator Controls
The operator control panel is furnished with five push-button switches.
UP—This push-button switch is used in conjunction with the menu-driven display to move the
cursor or highlight up. On some setpoint and calibration screens, this push-button switch is also
used to increase values.
DOWN—Similar to the UP push-button switch, the DOWN push-button switch is used in con-
junction with the menu-driven display to move the cursor or highlight down. On some setpoint
and calibration screens, this push-button switch is also used to decrease values.
SELECT—This push-button switch is used in conjunction with the menu-driven display to select
the highlighted item.
ALARM RESET—This push button is used to clear all latched inactive alarms. All active alarms
remain in memory until the condition is corrected and the alarm has been reset. The alarm reset
switch is also used to clear the History Status Report memory buffer. After the alarm condition
has been corrected, pressing and holding the alarm reset push-button switch for at least 5 seconds
will clear the History Status Report memory buffer.
ALARM SILENCE—This push button is used to acknowledge an active alarm. Pressing this
push button will silence the audible alarm.
2.3 Liquid Crystal Display
The operator control panel is furnished with a high visibility, full-graphics Liquid Crystal Display
(LCD) as the primary means of communication between the operator and the static switch con-
trols. The menu-driven LCD provides comprehensive monitoring and control of the static switch.
The LCD is active as long as at least one input to the static switch is energized and the Control
Power switch (located inside the static switch) is ON.
