UM348-1 MAINTENANCE

6.0 MAINTENANCE

The Field Mounted Controller's (FIELDPAC's) maintenance requirements are minimal. Activities such as cleaning and visual inspection should be performed at regular intervals. The severity of the FIELDPAC's operating environment will determine the frequency of maintenance. Additional topics including troubleshooting, assembly replacement, and software compatibility are also covered.

6.1 TOOL AND EQUIPMENT REQUIREMENTS

The following tools and equipment are necessary for servicing:

A. Common electronic hand tools

B. Digital Multimeter (DMM)

Voltmeter section

Accuracy ................ +/-0.01% of reading

Resolution .............. 1.0 millivolt

Input impedance ..... 10 Megohms

Ammeter section

Accuracy ................ +/-0.1% of reading

Resolution .............. 100 microamperes

C. Maintenance Kit, P/N 15545-110, containing wrist strap and conductive mat. This kit, or an equivalent, is required when a circuit board is handled for any reason.

6.2 PREVENTIVE MAINTENANCE

The objective for establishing a preventive maintenance program is to provide maximum operating efficiency.

Every preventive maintenance operation should assist in realizing this objective. Unless a preventive measure reduces a Station's down time, it is unnecessary.

6.2.1 Environmental Considerations

The FIELDPAC has been designed to operate within specified environmental parameters (temperature and humidity). These parameters are listed in the “Specification” section of this Instruction. Additional information concerning environmental contaminants is presented in the Installation section.

6.2.2 Visual Inspection

As part of a periodic maintenance program the FIELDPAC must be visually inspected. When viewing the assembly, scan for abnormalities such as loose, broken or stressed ribbon cables. Look for damaged circuitry and
