Rapid-Air STRAIGHTENER: SC SERIES - Manual (Page 6)


The main control console with
controls is mounted on the cabinet
of the straightener. located on the
face of the console are five switches,
one potentiometer, 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 straightener 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 posi-
tions 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” set-
ting 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.
