1) Set the following switch and 22-turn potentiometers to the settings given below:
switch
ZERO
FULL
D
CORE
STOP TIME
STOP MULT
2) Set the external TENSION pot full Clockwise.
3) Position the follower arm on an empty core.
4) Adjust the CORE pot to obtain zero on the remote meter.
5) Adjust the ZERO pot until the meter just starts to increase, and then reverse adjustment direction to
just return the meter to zero.
6) From published torque versus current curves adjust the CORE pot for the desired output current at
core. (Example: y madc to provide xx ft.-lb. at core)
7) Place the follower arm at the full roll position, and adjust the FULL pot to the desired output current at
full roll.
Setup is complete, and the DFC-90 is ready for operation.
Optional adjustments:
Stop Multiplier and Stop Time. The STOP MULT pot can be used to increase the torque while the
machine is stopping. The increased torque is applied when the RUN/STOP input is closed (terminals 17
and 18). The length of time the increased torque is applied is adjusted by the STOP TIME pot. The
STOPPED indicator illuminates when the Stop Time expires.

Operation
Tension is adjusted using the external 10 kohm tension pot.
Rewind taper can be adjusted using the FULL pot. The tension will decrease as the roll diameter
increases without changing the remote TENSION pot setting. Counter Clockwise rotation of the FULL
pot will decrease the tension at full roll, thereby increasing the amount of taper.
If the stop multiplier function is used, Clockwise rotation of the STOP MULT pot will increase the
stopping torque. Clockwise rotation of the STOP TIME pot will increase the time that the stopping torque
is applied. The STOP TIME may be adjusted from 0.2 to 60 seconds.
