Adjustment of the tilt adjustment feature is a one-time adjustment performed at initial installation. This unique shaft-mounted device yields the highest accuracy tachometer feedback. All errors associated with couplings and foot mounted tachometers are eliminated.

1. ADAPTER PLATE INSTALLATION - Reference Drawing1200A0101 sh.1, 1200A0101 sh.2, 1200A0101 sh.3

1.1 Prepare motor shaft by removing any dirt, debris, burrs, or other protrusions from the area where the adapter plate surfaces will come in contact with the motor shaft. A wire wheel, wire brush, sand paper, and files are tools needed for this procedure.

1.2 Using 9/16" open end wrench or Adjustable wrench, remove adapter plate from CC1200 Base Plate. (reference drawing 1200A0101 sh.1, 1200A0101 sh.2, 1200A0101 sh.3)

1.3 Clean the surface of the adapter plate to be mounted to the motor shaft.

1.4 Mount the adapter plate to the motor shaft with the hardware provided. Make sure the pilot and counter bore fits, and that the surface with the mounting screw holes is flush with the mounting surface. If the mounting holes are outside of the pilot or counter bore, the plate should be flush with the motor shaft. If the mounting holes are inside the pilot or counter bore, they should contact the motor shaft leaving a small gap between the motor shaft and the adapter plate outside the pilot or counter bore area. Torque Screws 30-35 Ft.-lbs.

2. MOUNTING CC1200 TACHOMETER TO ADAPTER PLATE - Reference drawing 1200A0101 sh.1, 1200A0101 sh.2, 1200A0101 sh.3

Tools required: 9/16" open end wrench or Adjustable wrench

2.1 Clean the mounting surfaces of the adapter plate and the CC1200 Base Plate.

2.2 Mount the CC1200 with the (6) 3/8-16 hex bolts provided and torque 25-30 Ft.-lbs. The CC1200 Base Plate should be flush with the adapter plate. If not, remove the CC1200, clean again and remount flange.

3. TILT (RUNOUT) ALIGNMENT PROCEDURE - Acceptable Tolerance +/- 0.001" Reference drawing 1200A0102 sh.1, 1200A0102 sh.2

Tools required: 3/16" long arm hex key, 9/16" open end wrench or Adjustable wrench, and 1" dial indicator* scaled by 0.001" with magnetic stand

*Dial indicators scaled by 0.0001" can be used, but it is best to start with above indicator until tilt (run out) is roughed to approximately 0.01"

Objective: To align the CC1200 tach +/- 0.001" perpendicular to the motor shaft.

3.1 Use the (3) 3/8-24 oval point socket head set screws with nylon in the CC1200 Base Plate for adjusting tilt (runout.)

3.2 Set the dial indicator on the CC1200, see drawing 1200A0102 sh.2.

3.3 Rotate the motor shaft identifying the highest reading on the dial indicator. Because of the three tilt adjusting screws, the high reading for this alignment can be located between two screws.

3.4 Stop the motor shaft as close as possible to the dial indicator high reading. Set the dial indicator to zero. If this is in between two screws, mark the location with a magic marker.

3.5 Rotate the motor and record the difference between the high and the low readings.

3.6 Stop the motor as close as possible to dial indicator and the high reading as in 3.4.

3.7 Take the 3/16" hex key and screw in on the high area. The dial indicator should move in the direction of the low. Adjusting just half the difference.

3.8 Adjust using the screw points as close as possible. If tilt adjustment is acceptable (+/- 0.001"); proceed to section 4; if not acceptable, continue with 3.8.1 for fine adjustment to acceptable tolerances.

3.8.1 The high point may be located at a screw, or between two screws. In order to bring the tilt into acceptable tolerance it is most likely the case where two screws will need to be adjusted independently, but in combination with each other. This procedure will be trial and error. First make an adjustment with the screw that is the highest, then adjust the other screw. Set dial indicator to zero, rotate the motor and record the amount difference. Going through the process of tightening, loosening, rotating and recording, will bring the tilt into acceptable tolerances.

NOTE 1: The CC1200 adjustment screws are not flush with the adapter plate at time of shipment. It will take several turns of the tilt screw before coming in contact with the adapter plate. These screws have a nylon insert and will require more torque to screw into the base plate.

NOTE 2: In rare cases where the tilt adjustment screws have been screwed in as tight as possible, but still more adjustment is needed, take the 9/16" open end wrench and break the 3/8-16 bolts mounting the CC1200 to the adapter plate, see drawing 1200A0102. Only break the screw or screws where adjustment is needed, (high) do not break the low screw(s). Break is defined as turning a fraction of a turn, where the relief of stress due to the force exerted on the screw is removed. Because of this force in order to break the screw sometimes the screw(s) are loosened too much. Just snug the screw(s), not applying more than 20 in.-lbs. of torque to the screw. Continue to adjust. If more adjustment is needed, repeat this process. Continue until tilt adjustment is acceptable.

4. Stabilizer Bar Installation - Reference Drawing 1200A0103

4.1 Mount stabilizer bar to CC1200 torque arm making sure that the insulated spacers provided are mounted on each side of the torque arm as shown in drawing 1200A0103. Torque 10-15 Ft.-lbs.

4.2 Mount stabilizer bar to angle bracket, not provided, with the insulated spacers mounted as shown in drawing 1200A0103.

5. MS Connector Installation - Reference Drawing 1200A0104

5.1 Tachometer Supplied with Mating Connector Only

5.1.1 Reference MS connector wiring drawings 72325B005 without a Z pulse, or 72325B006 with a Z pulse, or 72325B015 for Resolver, for wiring to MS connector mating socket, provided.

5.1.2 Screw mating connector onto bulk head connector so that approximately two threads remain visible on the bulk head connector, as shown in drawing 1200A0104.

5.2 Tachometer Supplied with Mating Connector and Cable or (JB) Junction Box Option

5.2.1 Reference 5.1.2 for proper connector mounting.

NOTE: If Tach is a (2T) with multiple outputs, or (1T) with Resolver, or (2T) with Resolver, it is extremely important to correctly identify tach bulk head connector with appropriate mating connector. Reference outlines drawings that are provided with each tach.
