Archived 3/18/10 MODEL 2087 TURNTABLE SERIES Assembly Instructions ASSEMBLY INSTRUCTIONS The installation of turntables 2 meters and larger will be performed by a factory installation specialist or by individuals who have been authorized by ETS-Lindgren to do such work. Proper installation of the turntable directly affects performance. The following installation information is provided to familiarize the user of the turntable with the installation process. 1. Uncrate all parts.

Archived 3/18/10 Assembly Instructions MODEL 2087 TURNTABLE SERIES 6. Connect the fiber-optic control cable and install the power connection per local electrical code. The standard power configuration is 230 VAC 50/60 Hz. CAUTION Electrical connection should only be performed by a qualified electrician and subject to local electrical codes. CAUTION Keep all body parts away from the drive pinion when the turntable is energized. 7.

To maintain the proper spacing between the turntable and the ground ring, it may be necessary to shim or pull the ground ring into position before fastening. ELECTRICAL INSTALLATION CAUTION It is important that this electrical installation procedure be performed by a qualified electrician, in accordance with local and national electrical standards prior to energizing the unit.

Archived 3/18/10 Electrical Installation MODEL 2087 TURNTABLE SERIES Should it be desired to operate at 115 VAC, jumpers in the relay enclosure assembly can be reconfigured. Consult the factory for safe and proper modification of the jumper configuration. Prior to changing these jumpers, insure that power has not been supplied or has been safely removed from the assembly. The jumpers provide a means for applying the proper voltage to both the internal power supply and to the electric motor.

Archived 3/18/10 MODEL 2087 TURNTABLE SERIES Setting Travel Limits fiber optic cables as straight as possible from the connector to the protective sheath. Using the Model 2090 Position Controller (or hand controller), rotate the motor base shaft to verify proper operation. Run the motorbase down to the lower limit CCW and then back it off from the lower limit just a bit. The previous step will help when it is time to set the rotation limits for the turntable.

Archived 3/18/10 Setting Travel Limits MODEL 2087 TURNTABLE SERIES 5. Disengaged the limit mechanism by loosening the inline coupler and sliding the coupler at least ¼ inch back from its mate to disengage the drive teeth. 6. Retighten the shaft set screws on the coupler. 7. Reinstall the cover and the adjustment knobs. Once limits have been set or disengaged using the above procedure, return the turntable to its original position by replacing the top section. 12 © EMC TEST SYSTEMS, L.P.

Archived 3/18/10 MODEL 2087 TURNTABLE SERIES Operation OPERATION Please refer to the Model 2090 Positioning Controller manual if you are unfamiliar with the operation of the unit. A 2090 manual is included with each 2090 shipment and is also available for download from our website: www.ets-lindgren.com. With the assembly complete the Model 2090 controller will need to be connected to the unit and power applied to both the motor base and controller in order to continue.

Enter this value for the encoder calibration value and reset the limits and position information. 7. Test the turntable by moving it a complete revolution and comparing the alignment marks. It may be necessary to adjust the encoder calibration value up or down slightly depending on the result.

Archived 3/18/10 MODEL 2087 TURNTABLE SERIES Operation SETTING CURRENT POSITION ON 2090 The total travel between the mechanical limits is typically set between 370 and 400 degrees at the factory. Set the 0 degree position on the 2090 so that the 2090 moves the table between the mechanical limits without engaging them in normal operation. EXAMPLE (CW - clockwise, CCW - counterclockwise) The table is rotated CCW until it stops at the mechanical limit. The table current position is then set at 0.

Archived 3/18/10 Hand Control Unit MODEL 2087 TURNTABLE SERIES HAND CONTROL UNIT To connect the Hand Control Unit (HCU), remove the connector cap on the motor base. Plug the cable receptacle from the hand control unit into the electrical enclosure and screw connectors completely together. The HCU is now ready to operate. Be sure to coordinate use of the unit with the operator of the Model 2090 Positioning Controller.
