INTRODUCTION
FIGURE 3
The TB800 Booster Amplifier amplifies control signals from Nexen tension controls into the electric signals needed for
operatingan electro-magneticbrake orclutch.
• Variable output signal varies directly with input signal
• Constant current output circuit
• Externalpotentiometerorsignalinputoperation
• Adjustableoutputrange
Functions:
INSTALLATION
1. Install the TB800 Booster Amplifier in a shock and
vibration free area that has an ambient temperature
of less than 120°F [50°C] and more than 32°F [0°C].
2. Mount the TB800 securely using 4 M5 screws. See
Figure 1 for mounting hole dimensions.
3. Use 18 AWG [0.9 mm2] wire rated for 600V when
connecting the output to a brake or clutch.
4. Set the AC Select connector to the supply voltage
used (100, 110, 200 or 220 VAC). (See Figure 4)
5. Connect the Brake/Clutch, AC Power Supply and the
Control Signal to the TB800.
NOTE: Refer to Figure 2 if amplifier is operated with an
external control signal (0-10VDC)*. Refer to Figure 3 if
amplifier is operated manually with an external
potentiometer.

Output Adjustment
NOTE: Adjust the output current according to the rated
current of the brake/clutch being used.
NOTE: Brake/Clutch must be connected to the TB800
before making proper adjustments.
1. Connect an ammeter in series to the brake/clutch.
(See Figure 5)
2. Turn the NFG potentiometer fully clockwise. (See
Figure 4 and 6)
3. Adjust the input control signal to full scale or
set the external potentiometer to maximum.
4. Apply ACPower.
5. Slowly turn the NFG potentiometer
counterclockwise until the rated output current
is obtained.

Compensating Input Voltage
NOTE: The TB800 can be used with a control signal
withinavoltage rangeof0-5VDCto0-10VDC. TheTB800
is calibrated for a 0-10VDC signal. If a different voltage
rangeis used,additional adjustmentsare needed. Follow
this procedure for the set up of a specific voltage range.
1. Turn the ATT potentiometer fully counterclockwise.
(See Figure 7)
2. Set the input control signal to maximum.
3. Turn the ATT potentiometer clockwise until the
voltage between check pins COM (-) and TP2 (+)
is 4V. (See Figure 8)
4. Perform steps for Output Adjustment in
