DISPLAY
The Excela features a large, easy-to-read display, showing the process condition and the status of the switch. (See program-
ming section for a complete description.) Setpoint and minimum/maximum process values can be easily accessed from the
front of the unit while in operation. Programming and interrogating the Excela is done through two buttons on the faceplate.
The Excela features a large, easy to read LCD display. It is used for three main purposes:
• Process value indication
• Programming of key features
• Switch status/troubleshooting.
In the process display mode:
• Pushing the left
o
button once, the display will scroll the min/max process values and the number of switch trips. The dis-
play will revert back to the Process Display mode after scrolling.
Note: While scrolling you can clear the values by pushing the right
g
arrow.
• Pushing the right
g
button once, the display will scroll setpoint, Rise and Fall. The display will revert back to the Process
Display mode after scrolling.
ALARM CONDITION
When the process goes beyond the Rise setpoint, the Green LED will change to Red.
The Red LED will continue to flash until the process has returned to a value below the Fall setting, at which point the Green
LED will flash again. If latch mode is activated, the Red LED will continue to flash even if the value drops below the Fall set-
ting. Refer to Latch function on page 5 to clear a latched output.
Note: The LED color should be set to Green for ‘FALL’ alarm points. Refer to LED flip function on page 4.
