4.0 Turntable Installation Considerations Before assembling, installing, or connecting any components, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. Pre-planning is essential for a successful installation. Discuss your requirements will your sales representative and request dimensional drawings prior to site construction. Before You Begin—Precautions Read this manual completely before starting installation.
Do not, at any time, place hands or feet in the vicinity of the drive pinion on the turntable. Power and Signal Lines CONDUIT Power and signal line paths should be planned in advance. Conduit should be in place before pouring concrete or installing the ground plane. Consider the size of the cable bundle when selecting conduit diameter.
5.0 Electrical Installation Before assembling, installing, or connecting any components, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. Electrical installation must be performed by a qualified electrician, and in accordance with local and national electrical standards. Model 2181 Electrical Installation The Model 2181 Turntable is configured to operate using 200-230 VAC, single phase, 50/60 Hz service.
To feed the fiber optic connectors through the waveguide in a chamber, it may be necessary to remove part of the protective sheath. This removal allows the connectors to fit through the hole without excessively bending the fiber optic cable. Find and mark the spot where you will need to remove the sheath. Use a sharp knife to carefully cut around the outside of the sheath at each end of the defined area.
6.0 Assembly and Installation Before assembling, installing, or connecting any components, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. Prior to assembly and installation, see the drawings located in the back pocket of this manual. Proper installation of the turntable directly affects performance.
4. The drawings in the back pocket of this manual show the placement of floor plates and leveling screws to anchor and level the turntable. Anchor the turntable through the attachment holes using the concrete expansion bolts provided. After installing the floor plates and leveling screws, level the entire turntable by adjusting all the leveling screws between and under the casters, and in the center section of the turntable. 5.
When the turntable is positioned as close as possible to the center, attach the measuring bar to the brass spacers mounted onto the bearing. Appropriate hole-mount locations correspond to the size of the turntable. Rotate the bearing and make sure approximately 7/8-in to 1-in spacing exists between the edge of the outer measuring bar and the diameter of hole cut into the pit. Adjust as required.
The turntables have a quantity of floor flange pieces depending on the size of the turntable. All flanges are pre-cut at the factory for a drop-in fit. A 2-meter Model 2181 is depicted in the following. The turntable top is shown as a partial cut-away to provide a view of internal components. 1. Lay the floor flange into the opening of the raised floor and push outward to the diameter of the opening. 2. Attach the turntable top onto the center bearing with the hardware provided. 3.
6. Continue mounting until all screws are installed. Some screws may fall between the floor panel joints. Try to position the flanges, making sure as few screws hit these points as possible, and making sure that the first or last hole in the flange is not too close to one of these joints. Trim the top floor joint strips to fit up against the flange. Floor Flange Installation in a Concrete Pit Installing in a concrete pit is the same as a paneled floor, with the exception of the mounting hardware.
• Small flat blade screwdriver • Phillips #2 bit driver • Adhesive tape INSTALLATION STEPS 1. Choose a location for the IR infrared sensor that is away from traffic. 2. Using a 1-in hole saw, cut an opening in the floor for the IR sensor. 3. Connect the V+, GND, and SIG wires to the IR sensor as shown in the diagram, and feed the cable through the hole. 4. Use the 1/16-in drill bit and four flathead mounting screws to mount the IR sensor collar. 5.
7.0 Operation Before placing into operation, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. If you are unfamiliar with the operation of the controller, see the Model 2090 Series Multi-Device Controller Manual. A manual is included with each positioning controller shipment and is also available for download from www.ets-lindgren.com.
Key Function INCRM, DECRM, or ENTER Once the desired limit, position, or parameter is visible in the display window, press INCRM, DECRM, or ENTER to toggle into edit mode. The lowest adjustable digit will flash on and off. LOCAL Press the LOCAL key for that device to switch the flashing digit to the next higher digit. In this way, it is possible to rapidly adjust any digit of a multi-digit parameter or limit.
3. Set the mechanism to the CCW armed position and insert actuation pins in the holes on either side of the mechanism 45 degrees away. 4. Set the current position displayed by the controller to 000.0 degrees. 5. Test the lower limit by holding down the DEC key, which allows the turntable to travel past the soft limit. The turntable should engage the lower hard limit between -35 and -55 degrees.
Turntable Encoder Calibration Parameter C, the encoder calibration parameter, calibrates the encoder counts to the rotation of the turntable. For the Model 2181, parameter C must be set to 3660. This setting is used to convert the encoder count values returned from a motor base into the corresponding centimeter or degree position reading. For turntables, this represents the number of encoder counts per revolution.
TURNTABLE CALIBRATION EXAMPLE • The turntable is set at the 0 degree position. A piece of tape is placed on the edge of the turntable to line up with the edge of the gearbox cover. The turntable is stopped when the tape travels exactly 360 degrees around. The display on the controller now reads 356.3 degrees, which is recorded. • The table is rotated CCW back to zero. The parameter button is set on the C setting. The C digits display 3430. A new C setting is now calculated: New C = (356.
Do not operate the turntable in a stalled condition. Doing so may cause damage to the drive unit and will void your warranty. Always make sure that the minimum speed setting specified in the S1-S8 parameters is above the minimum value at which your turntable will rotate under normal load. Speed Selection For the variable speed turntable, the Polarization/Flotation button provides the ability to cycle between eight preset speeds.
SSn: Set speed value • n = 1-4 • Command is valid only for a variable speed turntable • Valid speed values are 1-255 • Command Usage: SSn • Example: Output 708, SS1 196 SSn?: Query speed value • n = 1-4 • Command is valid only for a variable speed turntable • Returns a speed value 1-255 • Command Usage: SSn? • Example: Output 708, SS2?
