Compensating Input Voltage
NOTE: The TB800 can be used with a control signal
within a voltage range of 0-5VDC to 0-10VDC. The TB800
is calibrated for a 0-10VDC signal. If a different voltage
range is used, additional adjustments are 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
