Calibration
The control has been factory calibrated and no further adjustments
should be necessary. However, since the control was calibrated
using a speed adjust pot (P1) of 10K ohms and the pot shipped with
the control has a tolerance of ± 5%, the maximum speed could be
higher or lower than 1800 RPM. If the maximum speed is not
satisfactory, if the control has been repaired, or if you want to make
any changes, then follow the procedure listed below.
1.
Disconnect the power line.
2.
Set the speed adjust knob to “0” (full CCW).
3.
Set the MAXIMUM SPEED trim pot to full CCW (refer to Figure
3 on page 13).
4.
Set the REGULATION trim pot to full CCW (refer to Figure 3 on
page 13).
5.
Read and follow the SAFETY WARNING on page i.
6.
With no load on the motor, apply 115 VAC to the control and
advance the speed adjust knob to “100” (full CW).
