1 STYLE 3678 Conquest and 3878 Vanquish SST Monitor DRIVE COUPLING REPLACEMENT INSTRUCTIONS Applies To: Zone &, Zone with Handwheel, Zone &, and Vanquish SST Monitors The following is intended to provide the basic instructions for replacement of the elevation and rotation joint motor drive couplings. Read and understand these operating instructions before use. 66

2 Product Warnings Indicates a hazardous situation which, if not avoided, WILL result in death or serious injury. Indicates a hazardous situation which, if not avoided, COULD result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. Addresses practices not related to personal injury. Disconnect power and disable flow before maintenance. Keep all personnel out of the Danger Zone, in front of the outlet of the monitor when the water source is attached. Dangerous flow velocities can cause serious injury. Use only for firefighting by trained operators. Read and follow the operating instructions before use. The monitor uses current limiting for both the monitor and nozzle. Use only appropriate Akron Brass Company nozzles. Replace the identification tags if they should become worn or damaged. The monitor, nozzle, logic box, control box, tether controller, and field adjustable stops are made for optimal performance. Do not alter in any manner. The monitor was designed for use with the Akron nozzle. Use of any other nozzle could affect the speed or operation of the unit and should be tested before being put into service. During freezing conditions the monitor must be drained to prevent damage.

6 Elevation and Rotation Joint Motor Drive Coupling Maintenance Instructions Rotation and Elevation Joint Motor Housing Removal:. Turn off power and lock out / tag out power switchgear.. For Zone & monitors, remove set screw from enclosure plug. 3. Unscrew enclosure plug (7) counterclockwise to remove. Page 6

7 4. Compare and note wiring configuration with diagram provided with kit. Cable Glands 5. Standard terminal layout for the rotation joint To Junction Box: Green, White, Orange, Yellow, Brown, Blue, Red, and Black. To Rotation Motor: Black, Blue, Grey, Green or Green/Yellow To Elevation Motor: Green, White, Orange, Blue, Red, and Black Page 7

8 6. Standard terminal block layout for the elevation joint To Rotation Motor: Green, White, Orange, Blue, Red, and Black. To Elevation Motor: Green or Green/Yellow, Grey, Blue, and Black To Nozzle Motor: Green, White, Red, and Black 7. Separate wire leads from terminal block coming into housing. Note position of cable glands and pull cables through cable glands. 8. Remove two motor cover bolts () 9. Unscrew motor cover (9) counterclockwise from housing adapter. 0. Remove seven socket head cap screws (33 and 34) from housing adapter (). Page 8

9 . Insert a /4 Allen wrench into the override socket and turn clockwise to drive the worm and motor housing assembly from monitor.. Remove four bolts (33) from housing adapter and pull out motor. 3. Remove old coupling from motor shaft by loosening set screw, pulling off coupling, and set aside. Do not discard drive key (05), it must be reused. 4.
