Rapid-Air STRAIGHTENER: SBX, SCX & SD SERIES - Manual (Page 9)

6. DANCER ARM LOOP HEIGHT AND RANGE ADJUSTMENT
A. Loop Range—The loop range switch adjusts the amount of travel that the dancer arm will
move to provide the full range of speed on the straightener. It has three positions with a “0” as
the least travel from slowest to fastest speed and a “2” has the most movement between slowest
to fastest speed.
B. Loop Height—The loop height switch is used for setting the start position of the control
arm. It has three positions with the “0” setting having the start position at the dancer arm rest
position and the “2” having the start position somewhat higher than the dancer arm rest posi-
tion. This setting will determine the dancer arm angle that the reel will start turning. This func-
tion is used to accommodate different thickness of material which would have a different bend
radius thus requiting the dancer arm to be at a height somewhat above the home position when
at rest.
7. LOOP ARM / EXTERNAL SWITCH
This switch is used to select whether the material loop is controlled by the dancer arm or an ex-
ternal loop control. If LOOP ARM is selected then the control will monitor the dancer arm
movement. If EXTERNAL is selected then the control will monitor whatever is plugged into
the “D-SUB” (25 pin) connector.
8. REMOTE INTERFACE PORT “D” CONNECTOR
This 25 pin connector, located on the lower portion of the console is used to communicate with
external loop equipment. The RSB, RTB, & RTA will plug into the port and can immediately
be implemented.
CAUTION: NEVER PLUG ANY TYPE OF COMPUTER OR NON RAPID-AIR
EQUIPMENT INTO THIS PLUG OR SEVERE DAMAGE COULD RESULT. AL-
WAYS CONSULT THE FACTORY WHEN INSTALLING DIFFERENT EXTERNAL
CONTROLS FOR ADVICE ON COMPATIBILITY AND WIRING INFORMATION.
