OPERATING INSTRUCTIONS CABINET REEL
INSTALLATION
1. The machine that you have just received is fully assembled and ready to be put into position. Due to shipment vibration the machine should be checked to be sure all screws and
bolts are tight; visually inspect the machine for damage parts due to shipment. If the machine was damaged in shipment, contact the carrier first to report the damage, and then
Rapid-Air.
2. Install the machine on a level surface with sufficient clearance for loading and unloading
coils.
3. The machine is completely self-contained and need only be plugged into a 20 amp, 120 volt,
60 HZ outlet. If an extension cord is used as the source to the machine, it should be a minimum #12 gauge wire to keep the voltage loss down and for electrical safety reasons.
See Drawing (fig. Man5)

The main control is located behind the side access cover. Fig. Man14 is an illustration of the
layout of the control panel. This diagram lists all the components and the approximate location
of each that could be used for troubleshooting the machine if a problem should occur. The reel
can be ordered with—120 vac (1 phase) input. Terminal 4 & 5 will not be used and cannot be
used unless the Ramm is changed to a 220 volt controller. If using 220 vac 1 phase wire as indicated by drawing fig. Man14. This unit cannot be used with 120 vac 1 phase input unless the
Ramm board is changed to a 120 volt controller.

Mechanical Operating Procedure
To Load or Unload a Coil Ring
a) If your reel has a fixed center shaft go to Step—1
b) If your reel has an adjustable center shaft go to Step—2
Step 1:
Release and remove the outer coil retainer from the shaft. Load or unload the coil ring. Replace and secure the outer coil retainer. The reel is now ready for production.
Step 2:
Release and remove the outer coil retainer from the shaft. If unloading, adjust the centering
arms to a position that they have released the coil. Remove the coil ring. If loading, place the
coil ring on the adjustable centering arms, adjust the centering arms until they are tight on the
coil. Replace and secure the outer coil retainer. The reel is now ready for production.
The dancer arm was designed to operate from either side of the reel. The main reason for this
was so the reel controls could be lined up on the same side as the punch controls.
To switch the dancer arm to operate on the opposite side that it is currently located on, first remove the counter weight it equipped with one, then turn the locking knob to disengage the lock
on the dancer arm hub. Remove the dancer arm and relocate it to the other side. Turn the hub
60 degrees and insert the dancer arm into the slot. Set to desired position. Turn the locking
knob until tight on the dancer arm. Then replace counter weight, if so equipped. The dancer
arm is now ready for production running.

DANCER ARM LOOP HEIGHT ADJUSTMENT
Eight different loot sensing arm operating positions are selected
manually during set-up. By incrementing the thumbwheel height
switch, the zero point of the dancer arm is raised from it’s rest position to the angle shown (as indicated 0-7). The dancer arm will move
from rest position to the angle selected before the pallet reel begins to
rotate.
DANCER ARM LOOP RANGE FUNCTION
30 degree—Loop sensing arm travels through a full 30 degree arc to
vary turntable rotation speed from slow to full speed as controlled by
% speed pot.
20 degree—Loop sensing arm travels through a 20 degree arc to vary
turntable speed from slow to full speed as controlled by % speed pot.
10 degree—Loop sensing arm travels through a 10 degree arc to vary
turntable rotation speed from slow to full speed as controlled by %
speed pot.
5 degree—Only the first 5 degrees of loop sensing arm travel is required to control turntable rotation from slow through full speed as
controlled by % speed pot.

START UP PROCEDURE
Prior to applying power to the machine the operator should review all the controls on the machine. A brief summary of the controls is listed below.
MAIN CONSOLE & CONTROLER
The main control console & controls are mounted on the end of the cabinet. Located on the
face of the console are four switches and one potentiometer which are explained below.
1. DIRECTION CONTROL— The direction control switch selects the direction the reel will
turn, clockwise or counterclockwise.
2. % SPEED POT— The % speed pot adjusts the maximum speed that the reel will rotate and
should be set to maintain a constant feed rate.
3. ON/OFF SWITCH— The illuminated switch is the main power switch for the controller. It
must be “ON” for the machine to function.
4. PAYOUT/REWIND SWITCH— The payout/rewind switch selects whether the dancer
arm will cause the reel to function at a low speed at the bottom of the arc and increase the reel
speed as the arm raises. (Payout); or cause the reel to function at a low speed at the top of the
arc and increase the reel speed as the arm lowers. (Rewinds)
5. RUN/STOP/JOG SELECTOR SWITCH— The switch selects between Run & Jog. If in
Run and the control arm is moved the coil plate will turn. If in Jog, the Jog button has to be depressed for the coil plate to turn.
6. JOG BUTTON— Used for intermittent movement of the coil plate, mainly for set up, speed
is adjusted on the 69100053 terminal board on the electrical control sub panel.
7. DANCER ARM LOOP HEIGHT & RANGE ADJUSTMENT—
a. Loop Range— The loop range thumbwheel adjusts the amount of travel the dancer arm will
move to provide the full range of speed of the pallet reel.
b. Loop Height— This thumbwheel is used for setting the start position of the control arm.
The setting determines when the pallet reel will start turning. Each position will move the operating angle of the arm so that top-to-bottom travel is located to accommodate specific material
and loop height requirements.
ELECTRICAL COMPONENT DESCRIPTION
69100034 board—proportional control board
69100035 board—rotational isolation board
69100053 board—terminal board
PC control board (RAMM) - D.C. motor board

TAUT STOCK
The Taut Stock feature monitors the loop between the reel and the external equipment. If the
loop gets small enough to possibly cause damage to the reel, the interface contacts change state
and stops the external equipment.
If it is desired to monitor the reel then the following write-up will explain how to connect and
adjust this feature.
The “TAUT STOCK” feature is built into the Rapid-Air board #69100035 and wires to external terminals 7-8-9. The terminal #9 is common and from terminal 8 to 9 is a normally closed
contact with power on the unit. Terminal 7 to 9 is a normally open contact with power on the
unit. These contacts are from “Relay 2” chip. See diagram. This relay has to be in place for
taut stock to work. There is also a 4 prong post labeled “JUMP” that has to be connected so
that relay 2 can be activated. To correctly apply the jumper, locate the post and then locate the
plastic 2 prong jumper, insert the jumper so that he left 2 vertical posts are covered. Once this
is in place the taut stock feature can be tuned.
To tune the taut stock, check that there are no connections on the terminals 7-8 & 9, except
those that were factory connected. Attach an OHM meter to terminal 9 & 8 with the meter set
to OHMS.
Start the reel and raise the dancer arm so that the reel is running at maximum speed. Raise the
dancer arm up to a point that the stock would be taut. Hold the dancer arm at this position and
adjust the pot “R9” of board 69100034 until the contact changes state. Release the dancer arm.
The contact should return to normal state. Raise and lower the dancer arm 2 to 3 times to insure
that the contact functions properly. Disconnect the OHM meter and connect the customer interface. CAUTION!

INTRODUCTION
The RAMM Full Wave Solid State DC Motor Speed Control represents the latest state of the
art design achievable through modern technology.
Features Include:
Integrated Circuitry
Used to control and amplify command and reference levels with both closed and open loop
feedback to provide superior motor regulation. (Speed changes due to load, line voltage, or
temperature variations are held to minimum levels).
High Quality Components
Selected and tested for proven dependability.
Transient Protection
Used to prevent failure of the power bridge circuit caused by voltage spikes on the AC line.
High Reliability
When used in accordance with instructions in this manual, the RAMM will provide years of
trouble free operation.
A. Initial Setup and Wiring
i. General Instructions
1. Install proper size Plug-In Horsepower Resistor.
(see table 2)
2. The RAMM can be connected to a standard 120V or 240V 50/60 Hz AC line (be
sure the AC input voltage corresponds to the control voltage rating and the motor rating). (e.g.
90-130 VDC motor on 120VAC and 180 VDC motor on 240 VAC)
3. Follow the recommended supply wire sizes as per table 3.
4. Follow the NEC and other electrical codes that apply.
CAUTION: SEPARATE BRANCH PROTECTION MUST BE PROVIDED ON 240V
CIRCUITS.

Fig. 1. Basic RAMM Connection Diagram
CAUTION: Do not bundle potentiometer connections (P1, P2, P3) and inhibit
connections (I1, I2) with AC line or motor wires.
B. VOLTAGE FOLLOWING. All models can be controlled with an isolated analog reference voltage (0-6VDC) in lieu of the main speed potentiometer. The voltage is connected to P2
(+) and F-. The control output voltage will linearly follow the input voltage. The source impedance of the input should be 10K ohms or less. The Min trimpot can be used to provide an
offset speed. If an offset is not required adjust the Min to 0+ or 0– speed as desired. The Max
trimpot is rendered inoperative in the voltage following mode. Use auxiliary trimpot to limit
the control range. If the input signal is not isolated, or is a current signal (4-20ma), the RASI240D) Signal Isolator must be used. It will allow direct connection to process controllers and
microprocessors.
CATUION: 1. The voltage feeding P2 and F– must be isolated form the AC line.
Do not ground P2 or F– to set up a zero ground reference.
2. Do not bundle signal wires to P
connections. If signal wires are over 18”, use shielded cables.
2 and F– with AC line motor
C. FUSING. The RAMM has provision for a built in AC line fuse and armature fuse. The AC
line fuse protects the control against catastrophic failure. If the fuse blows, the control is miswired, the motor is shorted or grounded, or the RAMM control is defective. The armature fuse
provides overload protection for the motor and control. Choose the proper size armature fuse
by multiplying the maximum DC motor amps by 1.7. On domestic 240 Volt AC lines, separate
branch circuit protection for each line must be used. All fuses should be normal blow ceramic
3AG or ABC or equivalent.
1. AC Line Fuse is chosen according to the maximum rating of the control:
12 AMP fuse for all motors up to 3/4 HP-90V and 1 1/2 HP-180VDC.
25 AMP fuse for all motors 1 and 1 1/2 HP-90v and 2 and 3 HP-180VDC.
12
(Use Buss ABC, Littlefuse 326 ceramic fuse or equivalent.)
2. Armature Fuse can be chosen in accordance with the fuse chart. Note: The armature fuse is
calculated based on the approximate full load DC current rating of the motor times a from
factor of 1.5. If motor has characteristics not consistent with these approximations, a different fuse value may have to be used. Fuses are available from your distributor.

ADJUSTMENTS AND CONTROL FUNCTIONS
WARNING: If adjustments are made under power, insulated adjustment
tools must be used and eye protection must be worn.
The RAMM has been factory adjusted to provide 0-full speed using the speed control knob.
Minimum and Maximum speed trimpots are provided to change the speed from other than 0full speed. The Acceleration (ACCEL) trimpot is provided to allow for a smooth start over an
adjustable time period each time the AC power is applied or the speed pot is rotated. The DECEL trimpot controls the amount of ramp-down when the speed pot is adjusted to a lower
speed. The Current Limit (CL, or torque output) adjustment is factory set to approximately 1
1/2 times the motor rating. The IR Compensation (IR) is factory adjusted to provide excellent
motor regulation under normal operation.
13
NOTE: In order for the IR comp and CL trimpot settings to be correct, the proper Plug-in
Horsepower Resistor must be installed for the particular motor and input volt age
being used. Do not attempt to change the settings of the trimpots unless absolutely
necessary since they are factory adjusted to near optimum settings.
The following procedure, presented in order of adjustment sequence, should be used when readjusting all trimpot functions.
Fig 2. ACCEL/DECEL
TRIMPOT ADJUSTMENT
A. Acceleration Start. The ACCEL is factory set at approximately .2 seconds. To readjust to
different times, set the knob to the desired position as indicated in Fig 2.
B. Deceleration. The DECEL is factory set to provide a ramp-down time of .2 seconds. To
change the ramp-down time, adjust the DECEL trimpot as indicated in Fig 2.
C. Minimum Speed Adjustment. If a higher than zero minimum speed is desired, readjust
the minimum speed by turning the speed control knob to zero setting (full CCW position).
Then adjust the Min. Speed Trimpot to the desired setting.
NOTE: The min. speed adjustment will affect the max. speed setting. Therefore, it is
necessary to readjust the max. speed after the min. speed is adjusted.
D. Maximum Speed Adjustment. Turn Speed Control Knob to full speed (maximum CW position). Adjust max. speed trimpot to new desired setting.
NOTE: Do not attempt to adjust the max. speed above the rated motor RPM since unstable motor operation may occur. For moderate changes in the max. speed, there will be a
slight effect on the min. speed setting.
E. Current Limit (CL/Torque Adjustment). CL circuitry is provided to protect the motor
and control against overloads. The CL also limits the inrush current to safe level during startup.
The CL is factory set to approximately 1.5 times the full load rating of the motor. (CL trimpot
is nominally set to approximately 65% of full CW rotation).
14
To set the CL to factory specifications adjust as follows:
1. Set speed control knob at approximately 30-50% CW rotation.
Set CL trimpot to full CCW position.
2. Connect a DC ammeter is series with the armature lead.
3. Lock shaft of motor (be sure CL pot is in full CCW position).
Apply power and rotate CL pot CW slowly until DC ammeter reads 1.5 times motor
rating (do not exceed 2 times motor rating, Max. CW position.)
NOTE: If only an AC ammeter is available, it can be installed in series with the AC line.
Follow above instructions; however, set AC amperage at .75 times motor rating.
F. IR Compensation Adjustment. IR compensation is provided to substantially improve load
regulation. If the load presented to the motor does not vary substantially, the IR adjustment
may be set at a minimum level (approximately 1/4 of full setting). The control is factory adjusted to approximately 3% regulation. If superior performance is desired (less than 1% speed
change of base speed from 0 to full load), then the IR comp. Should be adjusted as follows:
NOTES: 1. Excessive IR comp. will cause control to become unstable, which causes
motor cogging.
2. For tach feedback applications the IR comp can be set to minimum rotation
(full CCW).
1. Set IR comp. trimpot at approximately 25% of CW rotation. Run motor unloaded at approximately 1/3 speed and record RPM.
2. Run motor with maximum load and adjust IR comp. trimpot so that the motor speed under
load equals the unloaded speed per step 1.
3. Remove load and recheck unloaded RPM. If unloaded RPM has shifted, repeat procedure
for more exact regulation.
The RAMM is now compensated to provide minimal speed change under large variations of
applied load
