GENERAL
INFORMATION
2.3 VACUUM FLUORESCENT DISPLAY (VFD)
The VFD provides information about the control functions, the motor under test, and an auxiliary
input device (if connected). The displays, from left to right, are:
• POWER(expressedinhorsepowerorwatts)/AUXINPUT
• TORQUE
• SPEED
• MemoryIndicator
2.3.1 Contrast settings
The 6200 is shipped with the Contrast Setting at zero (lowest) in order to prolong display life. If it
is necessary to increase the Contrast for improved readability, execute the following steps:
1. Press SHIFT.
2. Press COM SETUP button.
3. Select CONTRAST until desired brightness is reached.
4. Press SHIFT to return to main menu.

Note: Before installing the 6200, you should become familiar with the
front and rear panels, as outlined in Chapter 2–Controls.
3.1 POWERING UP THE 6200
WARNING! TO REDUCE THE RISK OF ELECTRIC SHOCK, MAKE
SURE THE 6200 IS EARTH GROUNDED BEFORE
STARTING!
3.1.1 setting unit For line Voltage
The 6200 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 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.

Magtrol Model 6200 Open Loop Dynamometer ControllerChapter 3 – Installation
SETUP
3.1.2 Hardware ConneCtion
Do not overload or stall the motor. Prolonged overload can cause the motor to overheat.
Note: 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.
3.1.3 selF-test
After turning the power on to the 6200, the display panel will show all segments of the VFD
(series of rectangles), indicating that the 6200 is downloading the program.
When the program download is complete, themessage“MAGTROL6200”appears.
3.2 BASIC TEST SETUP
1. After the Model Display wappears, press the UNITS DISPLAY button and set current
output to 0% with Decrease/Increase Dial.
2. Start the test motor.
3. Allow the motor speed to stabilize at its no-load speed for a few seconds.
4. Press the BRAKE ON/OFF button to ON.
5. 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.
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 7 –
Troubleshooting.
