(1) Disassemble the module as described in Section 5.1.2.
(2) Remove the PC-327 Analog board as described in Section 5.1.3.1. Lay the circuit board
aside on an anti-static surface.
(3) Remove the retaining screw from the desired DH200 transducer. Lift the transducer
straight up to remove it. Make sure that the two (2) O-rings remain with the transducer as it
is removed from the adapter plate. Ensure that the adapter plate O-ring sealing surface is
clean and free of contaminants. See Figure 5.4 (above).
(4) Replace the DH200, making sure that the electrical connections are located on the outer
edge of the cubic design. Be sure that the two (2) O-rings are in place on the DH200 and
that O-ring surfaces are free of contaminants. The DH200 must fit the guiding pins
smoothly and be aligned with all other DH200 transducers. Tighten the retaining screw to
40 inch-ounces ±5 inch-ounces of torque.
(5) Replace the PC-327 Analog board as described in Section 5.1.3.1 and reassemble the
module. Ensure that the two hex-head standoff screws are installed on DH200 positions 2
and 15 and that they align with the two PC-206 mounting holes.
(6) Test your scanner to ensure proper operation.
5.1.5 Calibration Valve Solenoid Replacement
Following is a step-by-step procedure to replace the Calibration Valve Solenoids in a Model
9116 Intelligent Pressure Scanner. All Model 9116 scanners contain the purge and leak check
calibration manifold and contain two solenoid valves. Use the tools and follow the general
warnings already described at the start of Section 5.1.1. Refer to Section 5.1.6.5 for details
concerning solenoid O-ring replacement.
Note
The hex-head standoff screws used on DH200 positions 2 and 15 are
used to secure the PC-327. These hex-head screws should not be
over-tightened or else the screw may break. (Recommended 40
inch-ounces for all DH200 screws)
(1) Disassemble the module as described in Section 5.1.2.
(2) Carefully remove the two (2) Phillips-head screws from the top of the solenoid. Disconnect
the solenoid from connector P6 of the PC-322 Main Board Assembly. See Figure 5.5.
(3) If the either the new or old solenoid does not have a pluggable wiring harness at the
solenoid, the new solenoid wires will require crimp pins to be installed for insertion in the
P6 mating housing. The proper crimp pin is Molex part number 08-56-0110. After
installing the crimp pins to the solenoid wiring, remove the old crimp pins from the Molex
P6 housing and insert the new solenoid’s wiring. Ensure that the new wires are installed
in the same position as the old wires.
