69100034 TAUT STOCK OUTPUT
The 69100034 - proportional control board has a taut stock output. This output must
be wired to a solid state relay as the Max current draw is 20 ma. The solid state
relay’s contact can then be incorporated into the electrical control circuitry.
The output can be wired so that the relay is either on or off with the dancer arm down.
When the dancer arm reaches the set point for taut stock, the relay switches state.
The taut stock height set point is set by raising the dancer arm to a position that the
material is taut and then adjusting pot R7 so the output changes state. Lower and
raise the dancer arm a few times to check that the set point repeats and then the task
is finished.
The potentiometer that is located just below the taut stock terminal strip is used for
presetting the Max voltage output requirement for a particular drive. A Ramm DC
drive board needs 6 VDC for Max motor sped so turn the pot fully counter—
clockwise. A minarik drive board needs 10 VDC for Max motor speed so turn the pot
fully clockwise.
The following is a brief wiring diagram for the taut stock.
3 GRD.
2 10 VDC out with dancer arm down
1 0 VDC out with dancer arm down
If the existing taut stock is being used, do not change anything. This change was
incorporated so that the straighteners and other equipment without the direction
board have a taut stock option.
