WOODWARD 5466-316 Servo speed governor

Check cabinet, module mounting unit backplane assembly, digital output module and termination device for dust. Clean as necessary using an antistatic vacuum. If circuit board cleaning is necessary, refer to procedure. Every six months or during plant shutdown, whichever occurs first. Check all signal, power and ground connections that are associated with the digital output module. Verify that they are secure. Refer to procedure.PREVENTIVE MAINTENANCE PROCEDURES This section covers tasks from Table 6-1 that require specific instructions or further explanation. • Cleaning printed circuit boards and edge connectors. • Checking signal, power and ground connections.

Never clean electrical parts or components with live power present. Doing so exposes you to an electrical shock hazard. Wear eye protection whenever working with cleaning solvents. When removing solvents from printed circuit boards using compressed air, injury to the eyes could result from splashing solvent as it is removed from the printed circuit board.

Printed Circuit Board Cleaning 

There are several circuit board cleaning procedures in this section. These procedures cover circuit board cleaning and washing, cleaning edge connectors and circuit board laminate between edge connectors. Use the procedures that meet the needs of each circuit board. Remove all dust, dirt, oil, corrosion or any other contaminant from the circuit board. Do all cleaning and handling of the printed circuit boards at static safe work stations. Always observe the steps under SPECIAL HANDLING in Section 3 when handling printed circuit boards.

GENERAL CLEANING AND WASHING 

If the printed circuit board needs minor cleaning, remove dust and residue from the printed circuit board surface using clean, dry, filtered compressed air or an antistatic field service vacuum cleaner. To wash the printed circuit board: 1. Clean the printed circuit board by spraying or wiping it with isopropyl alcohol (99.5% electronic grade). Use a foam tipped swab to wipe the circuit board. 2. Remove excess solvent by using compressed air to blow it free of the circuit board.
