1. Make sure that all Magtrol Torque Transducers and electronic products are earth-grounded, to
ensure personal safety and proper operation.
2. Securely ground the 6400 Torque Transducer Display case by connecting a good earth ground
at the ground stud located on the rear panel of the unit. Use a number 12AWG, or larger wire.
3. Check line voltage before operating.
4. Make sure that torque transducers and motors under test are equipped with appropriate safety
guards.

DESCRIPTION
Magtrol’s Model 6400 Torque Transducer Display is designed
specifically for use with all TM, TMHS and TMB Torque
Transducers. This easy-to-use device powers the transducer
and utilizes high speed Digital Signal Processing (DSP) to
display torque, speed, mechanical power and direction of
rotation.
The 6400 can be used as a basic display, as an interface with
Magtrol TM Software or on the production line using its
pass/fail feature. The unit includes an auxiliary analog input
for the option of testing with an additional transducer and a
special tare function to help offset any slight residuals caused
by couplings or suspended loads. The 6400 also has IEEE-488
and RS-232 interface capabilities, allowing a PC-controlled
environment that can yield high data acquisition rates of up
to 100 torque and speed readings per second. With Magtrol's
TM Software (sold separately), the data for torque, speed
and mechanical power can be automatically collected, saved,
displayed graphically, printed or exported.
PASS/FAIL MOTOR TESTING
The Model 6400 comes with an easy-to-use motor testing
Pass/Fail feature. This feature is ideal for quick pass/fail
(go/no go) testing in production and incoming inspection
applications.
When the 6400 is operated in the Pass/Fail mode, one of
three readings is used as the tested parameter: torque, speed
or auxiliary transducer. The two parameters not used are set
with user defined upper and lower acceptable limits. As the
motor is loaded to the tested parameter value (for example,
speed), the other two parameters (in this case, torque and
transducer) will indicatePASS or FAIL. The display willshow
pass or fail, or can be toggled to display the actual values.

GENERAL
INFORMATION
2.3 VACUUM FLUORESCENT DISPLAY (VFD)
The VFD provides information about the control functions, the torque transducer, and an auxiliary
input device (if connected). The displays, from left to right, are:
• POWER (expressed in horsepower, kilowatts or watts) or
AUX INPUT (expressed in scale factor times the auxiliary input voltage).
• TORQUE
• SPEED
• Memory Indicator
• Overload Indicator (If the inputs exceed the range of the instrument, "-OL-" will appear in
the TORQUE or SPEED portion of the display. Once the condition has cleared, the unit
will automatically return to the main menu.)
2.3.1 CONTRAST SETTINGS
The 6400 is shipped with the Contrast programmed to the lowest setting in order to prolong display
life. If it is necessary to increase the Contrast for improved readability, execute the following steps:
1. Press and release SHIFT.
2. Press and release SETUP.
3. Press and release UP Sbutton twice. "Menu: I/O" appears in the display.
4. Press and release SHIFT. The display appears as follows:
POWER/AUX TORQUE SPEED
Figure 2–2 Contrast Setup Menu
5. Use UP Sand DOWN Tbuttons until desired brightness is reached (select from a range of
0 to 3).
6. Press SHIFT three times to return to main menu.
Note: The lowest possible setting should be used to achieve desired result.
Using a setting higher than necessary may cause display segments
to burn-in over a period of time, resulting in uneven illumination
from segment to segment.

3. Installation/Configuration
Note: Before installing the 6400, you should become familiar with the
front and rear panels, as outlined in Chapter 2–Controls.
3.1 POWERING UPTHE 6400
WARNING! TO REDUCE THE RISK OF ELECTRIC SHOCK, MAKE
SURE THE 6400 IS EARTH GROUNDED BEFORE
STARTING!
3.1.1 SETTING UNIT FOR LINE VOLTAGE
The 6400 will operate with either of the following power sources:
• 120 V 50/60 Hz
• 240 V 50/60 Hz
1. Find the line cord receptacle on the rear panel. The line cord is a detachable NEMA Standard
3-wire.
2. If changing the line voltage:
1) Locate the power entry module.
2) Remove the line cord.
3) Insert a screwdriver into the slot and open the fuse door.
4) Install the appropriate fuses for that voltage as marked on the rear panel of the unit.
3.1.2 SELF-TEST
Note: To make sure that the 6400 is operational, a Magtrol torque sensor
must be installed and connected to the 6400. It is not required that
the 6400 be connected to a computer.
1. Connect the 6400 to the torque transducer using a 14-pin to 6-pin signal cable.
