Set Point
TO DISPLAY THE SET POINT
The SET POINT is the value at which the output trips. The switched output will reset once the
process variable returns beyond the set point value plus (or minus) the deadband value
(depending on the SWITCH MODE selected). Example: For High Limit Alarm, if SP = 300,
Deadband = 50, switch energizes at 300 and de-energizes @ 250.
To display the SET POINT value, press the arrow key:
X.XXX psi
Set Point: X.XXX
NOTE: If there is no keypad activity for approximately 4 seconds,
the unit returns to normal operation.

NOTE: Attempting to select a Set Point value outside of the operating range will result in an error
message - "Out Of Range" - and the value will be ignored.

30 seconds, the unit returns to the normal operating mode and new data is NOT saved.
Deadband
The DEADBAND value is the difference, in units, between when the switched output energizes and
de-energizes. The DEADBAND operation will change based on the selected SWITCH MODE to be
either positive (above) or negative (below) the set point. The deadband value is always set as a
positive number (no negative values).

In High Limit Alarm and High Limit Shutdown mode,
the deadband is below the set point.
n
In Low Limit Alarm and Low Limit Shutdown mode,
the deadband is above the set point.
