Rapid-Air STRAIGHTENER / RAPID-ROLL: SA3 - SD with compact control - Manual (Page 8)


The main control console with con-
trols is mounted on the cabinet of the
straightener. Located on the face of
the console are five switches, one po-
tentiometer, one push-button and one
or two circuit breaker reset switches,
which are explained below.
1. ON/OFF SWITCH
This illuminated switch is the main
power switch for the controller.
on the 120 VAC straighteners, it
will be a toggle switch and on the
230 VAC version it will be a mushroom
push-button. it must be “on” for the
straightener to function.
2. RESET BUTTONS (circuit breaker)
120 VAC.
a. 15 amp – This is the main circuit
breaker for the straightener.
b. 3 amp – This is the main circuit
breaker for the “D-SUB” (25 pin)
connector. Any shorting or overloads
would trip this breaker.
240 VAC.
a. 3 amp – This is the main circuit
breaker for the “D-SUB” connector.
Any shorting or overloads would trip
this breaker.
3. RUN/STOP/JOG
SELECTOR SWITCH
a. if “RUn” was selected and the
dancer control arm was raised, the
straightener rolls would rotate. if
“SToP” was selected then none of
the functions would work. if “JoG”
was selected then the jog button has
to be depressed to have the straight-
ener rolls rotate.
4. JOG BUTTON
Used for intermittent movement of
the straightener rolls and mainly for
setup. The jog speed can be adjusted
by rotating the R3 potentiometer on
the 69100079 board in the control
sub panel.
5. % SPEED POTENTIOMETER
The % speed potentiometer adjusts
the maximum speed that the straight-
ener rolls can rotate regardless
of the dancer arm height. it should be
set to maintain a constant material
feed rate through the straightener.
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 position. This setting will
determine the dancer arm angle
that the reel will start turning. This
function 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 external loop con-
trol. 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. Always consult the factory
when installing different external
controls for advice on compatibility
and wiring information.
