NOTE:
Figure 5-1. 4195KS Series Controller Parts and Adjustments Locations
Prestartup Checks for 4195KS Series
Controllers
When performing the checks, open loop conditions
must exist. Refer to figure 5-1 for location of
adjustments.
Note
If the controller has the auto/manual
option (option E), be sure the
controller is in the automatic mode
prior to performing prestartup checks.
1. Connect supply pressure to the supply pressure
regulator, and be sure it is delivering the proper
supply pressure to the controller. Provide a means
of measuring the controller output pressure.
2. For controllers with remote set point (option M),
connect regulated pressure of 0.2 to 1.0 bar (3 to 15
psig) or 0.4 to 2.1 bar (6 to 30 psig) to the remote
set point connection at the top of the controller case.
3. Loosen two screws (key 6), lift off the
proportional band cover (key 36), and set the
proportional band knob between DIRECT and
REVERSE.
4. The process indicator should indicate the process
pressure. For example, with the process pressure at
50 percent of the input span, the process pointer
should be 50 percent (+/-1 percent) of its span.
Slight adjustment of the indicator zero screw may be
necessary. See figure 5-1 for zero adjustment and
locking screw location.
5. If desired, the accuracy can be verified at other
points on the scale. If the indicator appears to be out
of calibration, refer to the process zero and span
adjustment portion of the calibration procedure.
6. Install the proportional band cover and install two
screws (key 6).
Startup for 4195KS Series Controllers
It is recommended that the controller switching
points be set as described in the calibration
procedures.
