Rapid-Air STRAIGHTENER / RAPID-ROLL: SA3 - SD with compact control - Manual (Page 15)

The 69100034—Proportional control
board has a taut stock output. The
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 posi-
tion that the material is taut and then
adjusting pot R7 so the output chang-
es state. Lower and raise the dancer
arm a few times to check that the set
point repeats and then 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 needs
6 VDC for max motor speed 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.
