FORWARD

These instructions covering operation of your Franklin Roll Leaf Stamping
Press are necessarily general in nature. Specific information and additional
help in the operation of the press and decorating your parts are available
from Customer Service, Franklin Manufacturing Corporation, 692 Pleasant
Street, Norwood, Mass. 02062.

In these instructions, we have tried to outline how the press operates, how to
set it up, how to use it, and how to “trouble shoot” it. Before operating the
press, you should read the entire booklet.

If your press is equipped with accessories such as meter indicating heat
control, air head return, air slide table rotary table, etc., special instructions
are included with these standard instructions.

WARNING!!!

1. A hot stamping press applies high pressure with heat to article being

marked. Care should be taken by the operator to keep hands free of
the stamping area whenever the equipment is connected to air and
electricity. When handling large articles, hold them by the sides so
that the hands are not under the stamping head. When handling small
articles, loading onto fixtures should take place away from the
stamping area. A MANUAL OR AIR SLIDE TABLE SHOULD BE
USED WHEN STAMPING THESE SMALL PARTS.

A TRANSPARENT SAFETY GATE SHOULD BE INSTALLED TO
PROTECT THE OPERATOR. Because this Franklin press is so
versatile, it is impossible for Franklin to supply a universal safety gate or
slide fixture. A device should be made by the customer to protect his
operators. Do not hesitate to consult the manufacturer for advice or
quotations on custom built part loading devices, etc.

2. This press is furnished with 2 hand buttons wired so that an operator

must press both buttons to initiate a cycle. An antitie down feature is
standard on these presses (except where automatic loading features
are provided with presses custom built to order).

3. Any attempt by the customer to alter the wiring or construction of this

press which renders the two hand anti-down circuit useless IS
COMPLETELY UNAUTHORIZED AND PROBABLY WILL
RESULT IN SERIOUS INJURY TO THE OPERATOR.

4. This machine was thoroughly tested before shipment. Please

remember that any machine can malfunction for a number of reasons
beyond the manufacturer’s control. If the operator detects any
malfunction, this press should be immediately turned off and the shift
foreman should be notified at once.

5. It is extremely important to remember that when servicing or setting

up this equipment, electrical power should be shut off and the air line
completely disconnected to prevent accidental actuation of the
stamping head.

ON RECEIPT OF THE PRESS

Remove the upper portion of the crate from the skid; remove the bolts
holding the press and legs to the skid; lift the press with a sling and
mount on legs.

ELECTRICAL CONNECTIONS

Connect only to proper power source. It is a good idea to check the
voltage at an outlet before connecting the press. Check the tag on the lead
wire of the press to see whether your press requires 110, 230 Volt single
phase, 230 Volt three phase, 480 Volt single phase, or 480 Volt three
phase. Special voltages can be supplied when necessary. Please write for
details.

AIR SUPPLY

Air should be supplied through a minimum hose or pipe of 3/8” ID to
insure proper press speed. The press is capable of operating at up to 150
PSI with no damage to any component. Minimum available pressure
should be 80 PSI to 125 PSI, any less than 80 PSI will result in artificial
upper limits on available die pressures. If limited pressure is available at
all times, contact Customer Service for information on boosting output of
press on low pressure air.

REMOVAL OF PROTECTIVE METAL COATING

The coating on this machinery is easily removable with any petroleum
distillate such as kerosene. Just soak a rag and wipe off all sprayed parts
where necessary.

SPECIAL NOTE REGARDING ALL MODEL 8000 SERIES PRESSES

In order to prevent damage to the cam rollers in the press, packing has
been placed between the cam roller and the wedge cam prior to shipment.
This packing should be removed before the machine is activated. This
can be done by manually removing the packing from the top rear of the
wedge cam.

ELECTRICAL SYSTEM:

The machine uses three basic electrical circuits.
A 230 VAC three phase current is provided to the machine through a
separate disconnect box which is fuseable and located on the upper side
of the press. The 230 three phase current is wired through contactor
points to two banks of two cartridge heaters wired in series to the outside
legs of the input with the center line common to all four heaters.

A second set of lines from the fuseable disconnect switch is wired to the
primary side of a 230-120 VAC transformer in accordance with
manufacturer’s specifications.

A 120 VAC is taken from the secondary of this transformer and provides
current for the control elements of the press.

This circuit is fused with 10 amp cartridge fuses and is provided with a
control toggle switch which is located in the upper left-hand corner of the
control box panel.

A pilot light located directly above this switch and wired across the 120
VAC circuit, will glow when this switch is in ON position.

This control switch will also activate the solid state heat control. The
solid state heat control unit can be located inside the control box easily,
since it is the only unit composed of a printed circuit board with a small
relay in the corner.

Power for this unit is supplied to Terminals L1 and L2 on the top surface
of the board. A jumper is used between L1 to terminal C for the common.
The potentiometer located on the front panel of the control box is used as
a remote control for pre-setting the desired temperature. Wires from this
potentiometer are connected to P1, P2, and P3 on the circuit board.
(Green and White to P1------- Red and White to P2------- Black and
White to P3.)

A thermistor probe, which is located in the aluminum or heated portion
of the head, provides a signal to this unit to energize the normally open
contact when the heated head temperature becomes lower than the pre-set
temperature.

The two leads from the thermistor are connected to T1 and T2.

When the thermistor calls for heat, the circuit board generates a 24 volt
current to the small relay located in the corner of the control board. A
110 volt is generated across the contact points of the small relay to close
the 220 volt contactor, thus supplying current to the cartridge heaters.

A yellow pilot light, located on the panel directly above the heat
adjustment, will light and stay lit as long as the thermistor is calling for
heat.

The third major circuit is the dwell time control. This circuit provides the
necessary electric signals to operate the pneumatic units of the press.

The main control element of this circuit is a solid state timer.

This unit is also supplied with a plug-in relay, the contacts of which
provide 115 volt signals to the control pilot valve of the machine.

Power is supplied to this unit through Terminals 1 and 2 of the Terminal
strips located on top of the timer. A toggle switch (Head Switch) is
provided to turn this unit off and on and is also used as a safety switch
when it is necessary to work directly under the ram. A pilot light (Head
On) will light when this switch is in the ON position.

This timing unit is activated by the two hand switches on the press which
are wired to Terminals 10, 11, and 12. A jumper is connected between
Terminals 1 and 7 to provide a common for this unit. Terminal 9, which
is a normally open contact, will produce a continuous 115 volt current to
the solenoid for the period of time pre-set on the potentiometer located on
the face of the panel. A red pilot light is wired in parallel with this circuit
and will stay lit as long as current is being supplied to the solenoid. The
two leads from the dwell potentiometer are connected to Terminals 5 and

6. A toggle switch (Set Up Switch) Is in this circuit which allows
continuous current to the solenoid as long as this switch is open, making
it much more convenient to set the proper level of the work table with the
head in the DOWN position. The head will return to its UP position when
this switch is closed.

A micro switch located on the right side of the frame of the press and
activated by a cam which goes up and down with the head, provide the
pinch point circuit. The cam should be set so that the limit switch is
closed when the head is in the full DOWN position. The two leads from
this switch are connected to Terminals 3 and 4 on the timer.
