CHAPTER 7
DIRECT SUPPORT (INTERMEDIATE) MAINTENANCE INSTRUCTIONS
Section I. GENERAL
7-1. Scope
This chapter provides specific instructions for all maintenance functions authorized direct support maintenance personnel
by the maintenance allocation chart (Appendix B). Included are maintenance, troubleshooting and repair instructions.
7-2. Purpose
These maintenance instructions are for use following isolation of a J-SIIDS malfunction to the Capacitance Proximity
Sensor (CPS).
7-3. Periodic Checks and Services
There are no scheduled preventive maintenance procedures required for the CPS.
Section II. TOOLS AND EQUIPMENT
7-4. Standard Tools and Equipment
The CPS can be maintained with standard tools and a voltohmmeter.
7-5. Special Tools and Equipment
No special tools and equipment are required for direct support maintenance of the CPS.
Section III. TROUBLESHOOTING
7-6. Visual Inspection
Before troubleshooting the CPS make a thorough visual inspection. Check sensor cable and PCS for damage and
evidence of failure. Check CPS housing interior for presence of moisture of foreign matter.
7-7. Troubleshooting
If the CPS malfunctions refer to Table 7-1. Find the trouble that most closely corresponds to that encountered, note the
probable cause (s) and perform the corrective action (s) indicated. If the corrective action in Table 7-1 does not correct
the malfunction the trouble is in the circuit board assembly. Figure FO-1, (located in back of manual) PCS schematic
diagram and the preliminary checks given in Chapter 2 will help to identify the trouble.
CAUTION
Do not adjust R29 Sensitivity Adjust. This is a factory adjustment and calibration
procedures are not included in this manual.
