Installation
Environmental
Temperature
Turntable System Type 9640 will work reliably at temperatures from +5 to +40°C (+41 to
+104°F) in a relative humidity of up to 90% non-condensing at +40°C (+104°F). The safe
temperature range for storage is −25 to +70°C (−13 to +158°F).
Electromagnetic Compatibility
Type 9640 complies with the U.S. FCC requirements for class B digital devices.
Type 9640 is compatible with EMC standards EN/IEC 61000–6–1 and EN/IEC61000–6–3.
Power Supply
To ensure safe operation of Type 9640, make the following checks and adjustments be-
fore connecting the mains supply.
Mains Voltage Setting
Ensure that the Mains Voltage selector on the rear panel of Turntable Controller Type 5997 is
set correctly according to Table 1.1. If the supply voltage is in overlapping ranges, select the
setting which is closest to the supply voltage.

Turntable System Type 9640 – User Manual 2
Mains Fuse Rating
Ensure that the correct fuse is fitted:
• 100 – 127V: 316mA slow-blow (T316mA)
• 200 – 240V: 160mA slow-blow (T160mA)
Use only correctly rated fuses of the specified type. Do not attempt to short-circuit the fuse
holder or use “mended” fuses.
Mains Socket Connection
Once the mains voltage setting and fuse are correct, use the Power Cable AN0020 provided to
connect the mains supply to the mains input socket on the rear panel of Type 5997. Type 5997
has a high standard of safety insulation in accordance with Safety Class II of IEC61010–1 and
therefore need not be connected to the protective earth contact of a mains supply outlet.
Mounting
Four 6mm holes are provided for mounting Controllable Turntable Type 5960. These are
spaced at equal distances around the periphery of the turntable. The turntable can, if necessary,
be hung upside down. The maximum load in either position is 100kg (220lb.) at the centre of
the turntable, or 30kg (66lb.) on the periphery, when the table plate is lined up perfectly in the
horizontal plane.
For fixing a test object to the turntable, there are six tapped holes that will accept M5 or
10–32UNF screws. Three of these are positioned 65 mm from the centre of the turntable and
three at 145mm, at 120°angles. Alternatively, the removable chuck can be used. This accepts
rods of up to 16mm diameter and is located in the centre of the turntable.

Operation
Manual Use
Controllable Turntable Type 5960 can be manually controlled either from the front panel of
Turntable Controller Type 5997 or from Remote Control WB1254. Type 5997 allows you to set
the mode of operation and to initiate rotation, while the remote control allows you to control the
turntable once the mode of operation has been selected.
Use of Turntable Controller Type 5997
Setting Up the Turntable System
1) Switch Type 5997 on.
2) Press Mode repeatedly to step to the required operational mode.
3) Use “<” and/or “>” to select the required numerical setting (not relevant for Set 0°).
4) Press Enter to store the setup mode.
Note: When in setup mode (Mode pressed), Stop can be used to exit without accepting
changed parameters.
The operational modes, functions and available settings are detailed in Table 3.1.
Start and Stop
If Mode is set to TURN_REL, TURN_ABS or CONT, Start must be pressed to start rotation of
the turntable.
If Mode is set to CONT, rotation can be stopped at any time by pressing Stop.
Note: Stop has no effect on rotation for TURN_REL or TURN_ABS.
Rotating the Turntable
When not in setup mode, “<” and “>” rotate the turntable clockwise (negative angle of rota-
tion) and anticlockwise (positive angle of rotation), respectively.
BE124513.book Page 9 Friday, November 25, 2005 10:21 AM

Turntable System Type 9640 – User Manual 10
Table 3.1 Operational modes of Turntable Controller Type 5997
Inverted Turntable
Note: The direction of rotation, anticlockwise or clockwise, does not depend on the orientation
of the turntable. When Type 5997 is switched on, the position of a switch inside the turntable is
read. This ensures that “>” will always give anticlockwise rotation whether the turntable is on
its base or upside down.
Use of Remote Control WB1245
The remote control works in the same way as Type 5997 except that the only available mode is
Set 0°.
•TheMode key is therefore replaced by a Set 0°key.
Mode Function Range
TURN_REL When Start is pressed, the turntable will rotate by the
specified angle relative to its present position.
Positive angles give anticlockwise rotation.
−359°to +359°
TURN_ABS When Start is pressed, the turntable will rotate from its
present position to the specified angle relative to the 0°
reference angle.
If MAX_360 is OFF, rotation is clockwise or anticlockwise,
dependent on which angle of rotation is smallest.
If MAX_360 is ON, the turntable will rotate in the direction
required to avoid cable wrapping.
0 to 359°
CONT. (s/r) When Start is pressed, the turntable will rotate
continuously at the speed specified. If MAX_360 is ON,
the turntable will stop after one rotation. The turntable
can also be stopped at any time by pressing Stop.
The + or – sign before the speed indicates the direction
of rotation: positive values give anticlockwise rotation.
±22.7 to ±720 seconds/
revolution.
Note: The “<” and “>” keys
work in the sequence
−22.7, …, −720, +720, …,
+22.7.
ACC. Sets the acceleration of the turntable. An acceleration
of, for example, 5 is constant regardless of the mass of
the device under test. Lower values of acceleration
should be chosen for heavy objects.
1 (min.) to 10 (max.)
MAX_360 When ON, rotation of the turntable is limited to one
revolution. This avoids cable wrapping when the
turntable’s slip rings are not used.
When OFF, rotation is unlimited.
ON/OFF
SET 0°Sets the 0°reference angle.
BE124513.book Page 10 Friday, November 25, 2005 10:21 AM

CHAPTER 3
Operation 11
This means that the turntable cannot be set up from the remote control but that, once the setup
has been made, all other options are available, including resetting the 0°reference angle.
IEEE Use
WARNING: Switch off all equipment before connecting or disconnecting the digital
interface. Failure to do so could damage the equipment.
Installing National Instruments™ IEEE–488.2 Hardware and Software

Note: The IEEE address switch is located inside Turntable Controller Type 5997. To
gain access:
1) Switch Type 5997 off.
2) Unscrew the screw at the top centre of the rear panel.
3) Slide the top of the unit off.
The address switch (S1) is situated in the top-left rear corner of the unit. The default setting is:
10001010
where the first figure, if set to zero, bypasses the “upside-down switch” (see “Inverted Turnta-
ble” on page 10), and the last five figures are the IEEE address.
Changing from Remote to Local
If the controller has sent REN (Remote ENable), the display of Type 5997 will show Remote
and operation from the front panel or remote control keys will be disabled.
To enable local operation (as long as a Local LockOut has not been sent), press the following
sequence of keys in quick succession:
1) Mode: The display shows Remote.
2) Mode: The display shows Go to local.
3) Enter: The display shows Local on.
You can now use Type 5997 or WB1254 to move the turntable until the next command is
received from the controller.
