4. Comparator-Switch / Loop Check Mode: Access by pressing MODE for less
than 3 seconds.
A. Comparator-Switch Setting: To activate / deactivate comparator-switch,
scroll to US1 (4-20mA version only) or US2 and select USE / noU. Enter com-
parator-switch set point by selecting A-1 or A-2 and use #/$ keys for pres-
sure setting. Now enter ‘deadband’ value (pressure difference between set
and reset values) by selecting b-1 or b-2 and use #/$ keys for setting. Note:
unit automatically configures the reset point. Increasing setpoint is entered as
a positive ‘deadband’ value, while decreasing setpoint is entered as a negative
‘deadband’ value.
B. Loop Check: Allows the user to check comparator-switch operation without
requiring pressure input. Use $ or # keys to view comparator-switch function
in a simulated test of the application.
