Nexen TB800 911542 - Manual (Page 5)

(1) FORM NO. L-21080-A-0700
INTRODUCTION
FIGURE 3
The TB800 Booster Amplifier amplifies control signals from Nexen tension controls into the electric signals needed for
operating an electro-magnetic brake or clutch.
• Variable output signal varies directly with input signal
• Constant current output circuit
• External potentiometer or signal input operation
• Adjustable output range
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 mm 2 ] 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 (0-10 VDC)*. Refer to Figure 3 if
amplifier is operated manually with an external
potentiometer.
