Before installing your 6200, you should become familiar with the front and rear panels, as outlined in Chapter 1-
Introduction.
CHECKING YOUR 6200
Do not overload or stall the motor.
Prolonged overload can cause the motor to overheat.
Make sure the 6200 is earth grounded before starting!
SETTING UNIT FOR LINE VOLTAGE
The 6200 will operate with either of the following power sources:
• 120V 50/60 Hz
• 240V 50/60 Hz
1. Find the line cord receptacle on rear panel. The line cord is a detachable NEMA Standard 3 wire.
2. Make sure the selector matches the power source
(numbers should match the line voltage).
If not:
• Locate the power entry module.
• Remove the line cord.
• Insert a screwdriver into the slot and open the cover.
• Slide the voltage selector so the desired line voltage appears in the window.
• Install the appropriate fuses for that voltage.
Figure 6.
Cover for Voltage Selector, Fuses
NOTE: To make sure that the 6200 is operational, a Magtrol dynamometer with a test motor installed must be connected to the 6200. It is not required that the 6200 be connected to a computer.
1. Connect the 6200 to the dynamometer using the following cables:
• 14-pin signal cable
• 2-pin brake power cable
2. Turn on 6200 power.
Desired results:
• The display panel will show all segments of the VFD (series of rectangles), indicating that the 6200 is executing a self-test routine.
• Message "MAGTROL 6200" appears.
• Normal display panel appears.
3. Press the UNITS DISPLAY button and set current output to 0% with Decrease/Increase Dial.
4. Start the test motor.
5. Allow the motor speed to stabilize at its no-load speed for a few seconds.
6. Press the BRAKE ON/OFF button to ON.
7. Turn the Decrease/Increase Dial clockwise.
Desired results:
• The torque reading will increase.
As brake power is applied, load is applied to the motor. The applied torque increases as the
Decrease/Increase Dial is turned clockwise. For most motors, loading is indicated by motor speed reduction.
7
Chapter 2 - Installation
8. Reduce the torque load to zero by turning the
Decrease/Increase Dial counterclockwise.
Desired results:
• The torque reading will decrease.
9. Press the BRAKE ON/OFF Button to OFF.
10. Turn off power to the test motor.
NOTE: If the desired results did not occur, please see Chapter 6 -
Troubleshooting.

4 - The 6200 with a PC (R emote Control)
The 6200 can be used with a personal computer to control a dynamometer and to transmit data from motor testing directly to the computer.
ABOUT THE GPIB INTERFACE
(General Purpose Interface Bus)
Magtrol instruments use the GPIB (IEEE-488 Standard) for computer-to-instrument interfacing because:
• The GPIB parallel interface is faster than serial interfaces.
• The GPIB enables testers to access up to 15 instruments on one port. Because typical motor testing requires that at least five separate parameters must be synchronized, a system of easy, fast access to more than one instrument is essential.
• The GPIB has rigid data formatting and hardware standards. These standards help to ensure that all functions will work properly when the hardware and software are installed.
NOTE: The GPIB interface is not standard on most computers. An interface card and driver software must be installed. Magtrol recommends National
Instruments Corporation hardware and software.
• An IEEE-488 cable must be installed between the computer and the 6200.

CHECKING THE 6200-TO-PC
CONNECTION
NOTE: Make sure that the 6200 and its host computer are communicating before acquiring data.
1. Make sure the primary address is set correctly for the 6200.
2. Set the input variable to 15 characters (13 variable characters and the two required data termination characters CR and LF. (See “Programming” in this chapter.)
3. Issue output data command "OD" and read 15 characters according to the instructions for your
GPIB interface.
Desired results:
• Torque/speed data will be returned
NOTE: If the desired results did not occur, please see Chapter 6 -
Troubleshooting.
2. Set the timeout for at least one second, if you are asked to set a communication fault delay timeout.
• If the communication fault delay timeout is too short, or if the computer resets the interface too quickly, the host instrument may stop responding.
6200 COMMAND SET
When entering a command code:
1. Type all characters in uppercase ASCII format.
2. End all commands with a CR-LF (hex 0D-0A).
3. Do not string multiple commands together in one line.
The character # represents a floating point numerical value following the command. Leading zeroes are not required.
PROGRAMMING
NOTE: Check the manual provided with your software for full instructions.
1. Use the following information to answer the formatting questions asked when installing your
GPIB software.
• All GPIB data acquisition systems requires the use of data termination characters. The 6200 uses the GPIB standard termination characters

Magtrol Model 6200 Dynamometer Controller/Readout Chapter 4 - The 6200 with a PC (Remote Control)
ACQUIRING SPEED-TORQUE DATA
Speed-torque data is a fixed-length string in ASCII format with a floating point decimal. Use the following string format:
SdddddTdddd.R[cr][lf] or
SdddddTdddd.L[cr][lf] where . . .
S = speed in RPM. No leading zeroes are used.
d = decimal digit 0 through 9
T = torque in units selected during setup. The torque value always contains a decimal point.
L = counterclockwise dynamometer shaft rotation (left)
R = clockwise dynamometer shaft rotation (right)
. = decimal point. The decimal point location depends on the specific dynamometer and torque range in use.
NOTE: The [cr] and [lf] characters will not display.
Example:
If a motor is running at 1725 RPM clockwise, with the dynamometer loading the motor to 22.6 oz.in., the 6200 will return:
S 1725T22.60R
By manipulating the string, the speed-torque and shaft direction (if required) can be extracted. Then separate numerical variables can be assigned to them for data processing.
SELECTING THE BAUD RATE FOR THE
RS-232 INTERFACE
The 6200 communicates with the host computer through a DB-9 interface connector. The connector pin-out is:
2-RX, 3-TX, 4-DTR, 5-GND. No other pins are connected.
Figure 8.
Connector Pin-Out

The 6200 is equipped with an RS-232 (serial) interface.
To select the baud rate:
1. Press SHIFT and release.
2. Press SETUP button.
3. Press DOWN " twice.
4. Press SHIFT three times.
5. Press the UP ! or DOWN " buttons to cycle through the following available baud rates:
300
600
1200
2400

9 Pin
(Computer)
3 2 6 5
A cable may also be purchased from your local electronics store. A Radio Shack #26-152 cable and
#26-264 null modem adapter are known to work. The null modem adapter must be used on the computer end of the cable.
15
CLOSED-BOX CALIBRATION
The 6200 features closed-box calibration. The advantage of closed-box calibration is that the user does not have to disassemble the case or make mechanical adjustments. However, the calibration of the Accessory
Torque Output must be done internally with Offset and
Gain trim pots.
The Torque readout and Auxiliary Input can be calibrated using external reference sources. Correction factors for Offset and Gain are stored in nonvolatile memory. They remain in effect until the user or the calibration house updates them.
The front panel displays the actual values for the ZERO and GAIN correction factors. Record these values before calibration. In the unlikely event of a Controller/
Readout failure, it can re-initialized by pressing and holding the STORE and RECALL buttons while turning the power on. All internal memory and setups will be lost. After re-initializing, reprogram the GAIN and
ZERO values into memory.
CALIBRATION SCHEDULE
Calibrate your 6200:
• After any repairs are performed
• At least once a year; more frequently to ensure required accuracy
BASIC CALIBRATION PROCESS
The basic calibration process consists of four procedures which must be performed them in the following order:
1. Initial Procedure
2. Torque Offset and Gain
3. Accessory Torque Output Offset and Gain
4. Auxiliary Input Offset and Gain
To calibrate the 6200, you will need:
• External voltage reference of 0 to 5 Volts DC
• Digital multimeter (DMM) with VDC accuracy of 0.05% or better

NOTE: Record the actual correction factors displayed before proceeding with calibration.
1. Allow the 6200 to stabilize in an environment with:
• An ambient temperature of 18°C to 25°C
• Relative humidity less than 80%
2. Turn on the 6200.
3. Allow the 6200 to warm up for at least 30 minutes.
4. Enable the calibration mode as follows:
• Turn instrument power OFF
• Press in and hold the UP ! and DOWN " arrow buttons simultaneously
• Turn instrument power ON
5. Continue pressing the UP ! and DOWN " arrow buttons until the display shows the software revision date.

The 6200 can also be calibrated by using a certified dynamometer, calibration beam, and weight instead of an external voltage reference.
NOTE: Magtrol suggests you do NOT use this method. By using the alternate calibration procedure, you are calibrating the 6200 to a specific dynamometer, not to a reference standard. If you connect the 6200 to a different dynamometer, the resulting torque reading may be incorrect.
1. Connect the chosen dynamometer to the 6200 using the 14-pin signal cable and the 2-pin brake cable.
2. Attach the calibration beam to the dynamometer shaft.
3. Enter the calibration mode.
4. Press the BRAKE ON/OFF button ON to apply full loading to the dynamometer.
5. Hang the weight on the calibration beam pin and level the beam.
6. Press the DISPLAY button.
7. Adjust the gain by turning the Decrease/Increase
Dial until the displayed voltage equals the reference voltage.

Chapter 5 - Calibration Magtrol Model 6200 Dynamometer Controller/Readout
NOTE: The magnitude of change per revolution can be increased by pressing the UP ! button or decreased by pressing the
DOWN " button.
8. Remove the weight for ZERO adjustment.
9. Press the UNITS DISPLAY button.
10. Adjust the Increase/Decrease Dial until the display indicates 0 mVDC.
NOTE: The mV output of the dynamometer will be equivalent to the Weight times Distance on the calibration beam, disregarding any decimal point.
Example:
Magtrol’s HD-400-6 Dynamometer has a fullscale torque of 40.0 oz.in. The distance from the center of the dynamometer shaft to the pin on the calibration beam is 5 inches. Placing an
8 oz. weight on the pin will produce a torque of
40.0 oz.in. The mV output of the dynamometer will be equivalent to 8 oz. multiplied by 5 inches, yielding an output signal of 400 mV.
11. Repeat steps 5 through 10.
12. After completing calibration:
• Press the BRAKE ON/OFF button OFF to remove loading from the dynamometer.
13. Remove the calibration beam from the dynamometer shaft.
14. Proceed with your desired motor testing.
