Adjustments for 4195KB and KC Series
Controllers
This section includes descriptions of adjustments
and procedures for prestartup, startup, and
calibration. Adjustment locations are shown in
figures 4-1 and 4-3. To better understand the
adjustments and overall controller operation, refer to
the Principle of Operation section and to the
schematic diagrams in figures 4-5 through 4-9.
Unless otherwise noted, key numbers given in this
section are found in figure 7-1.
Manual Set Point Adjustment
Adjust the set point by opening the controller cover
and moving the set point indicator until the line on
the set point indicator is over the desired value on
the process pressure scale. Move the indicator to
the right to increase the set point and to the left to
decrease it. Adjusting the set point does not affect
the proportional band setting.
Remote Set Point (suffix letter M)
Adjustment
CAUTION
Do not manually move the set point
indicator on a controller with remote
set point. Manually moving the set
point indicator could damage the
controller.
If the controller is equipped with remote set point
(suffix letter M), vary the remote set point pressure
to change the set point. Increase the pressure to
increase the set point and decrease the pressure to
decrease the set point.
