SECTION 1—IN GENERAL

Efficient and safe machine operation depends on the development, implementation and enforcement of a safety program. This program requires,

among other things, the proper selection of point-of-operation guards and safety devices for each particular job or operation and a thorough safety

training program for all machine personnel. This program should include instruction on the proper operation of the machine, instruction on the

point-of-operation guards and safety devices on the machine, and a regularly scheduled inspection and maintenance program.

Rules and procedures covering each aspect of your safety program should be developed and published both in an operator’s safety manual, as

well as in prominent places throughout the plant and on each machine. Some rules or instructions which must be conveyed to your personnel

and incorporated in to your program include:

Danger is used to indicate the presence of a hazard which WILL cause SEVERE

personal injury if the warning is ignored.

THIS SAFETY ALERT SYMBOL IDENTIFIES IMPORTANT SAFETY MESSAGES IN THIS MANUAL.

WHEN YOU SEE THIS SYMBOL , BE ALERT TO THE POSSIBILITY OF PERSONAL INJURY, AND

CAREFULLY READ THE MESSAGE THAT FOLLOWS.

A company’s safety program must involve everyone in the company, from top management to operators, since only as a group can any

operational problems be identified and resolved. It is everyone’s responsibility to implement and communicate the information and material

contained in catalogs and instruction manuals to all persons involved in machine operation. If a language barrier or insufficient education would

prevent a person from reading and understanding various literature available, it should be translated, read or interpreted to the person, with

assurance that it is understood.

SECTION 2—INTRODUCTION

Preliminary Steps Before Installation (continued)

4. Please make sure the machine is in first-class condition. Before starting any installation, it is essential that the machine is thoroughly

inspected. Be sure all mechanical components and all collateral equipment are in first-class operating condition. Your inspection should be

done according to the machine manufacturer’s installation and maintenance instruction manual. Special attention must be given to the machine

clutch and brake. The clutch and brake must be maintained in an operating condition which is within the specifications set by the machine

manufacturer. If you have any doubts or questions concerning the condition of the machine, contact the machine manufacturer for assistance.

Repair or replace all parts not operating properly before proceeding.

Inspection and maintenance programs must be established and implemented to keep machines in first-class

condition. Programs must include thorough inspections of each machine on a weekly basis and records kept of these

inspections. Any part of the machine that is worn, damaged or is not operating properly must be replaced immediately

or repaired before the machine is used.

5. Verify that the machine is in first-class condition and operating properly; shut off all power to the machine. Padlock all electrical and pneumatic

energy in the “off” position and do not actuate the machine again until the installation of all package components has been completed. Lockout/

tagout energy isolation procedures must always be practiced and enforced.

6. If the machine has a mechanical-friction clutch (usually found on older presses and press brakes), an air cylinder is required to engage and disengage

the clutch. Install the air cylinder in the most logical place to actuate the clutch. Please see the enclosed Installation Manual No. KSL-096 if an air

cylinder was ordered. Note: On machines equipped with air-operated friction clutches, an air cylinder is not required.

Safeguard Interlocks and Other Types Of Interlocks

SAFEGUARD INTERLOCKS

The machine will not operate or must not be operated until you either: (1) electrically interlock or (2) mechanically safeguard the machine’s point

of operation with a guard or device.

When an electrically interlocked method of safeguarding the point of operation is chosen, connect the interlock to the safeguard interlock

terminals (P8-17 and P8-18) in the control box, and as shown on the control wiring schematic (wire numbers 86 and 87). If a light curtain(s) is used

as the point-of-operation safeguard, it does not need to be interlocked in to P8-17 and P8-18 safeguard interlock terminals. Refer to the control

wiring schematic for proper terminal connection of the light curtain.

Point-of-operation electrically interlocked safeguards, when opened, prevent or stop normal machine operation during operator cycling modes.

Examples of these types of interlocks are barrier guard interlocks and gate device interlocks.

When a mechanical guard or device (nonelectrically interlocked) is chosen, the safeguard interlock terminals (P8-17 and P8-18) are not used. In

order for the machine to operate with the use of a mechanical guard or device, the safeguard interlock terminals must be connected. Please see the

wiring schematic.

The mechanical guard or device must be properly installed, used and maintained and must always prevent all

personnel from bodily injury.

If the mechanical guard or device is not used, is removed, or is defeated, an electrically

interlocked method of safeguarding must be used and connected to the safeguard interlock terminals (P8-17

and P8-18).

Never operate this machine without point-of-operation safeguarding.

Note: Additional equipment that can help safeguard machines includes indexing tables, electrically controlled sliding bolsters, and automatic feeding

systems. These systems usually require additional control logic circuitry. Please contact the factory for a quotation itemizing the interface equipment

necessary for these types of systems as well as others (see page 33). Please send complete schematics, including the hydraulic and pneumatic

systems, of the particular system to be interfaced.

SECTION 2—INTRODUCTION

OTHER ELECTRICAL INTERLOCKS

There are basically two types of electrical interlocks as applied to machine control circuitry:

• Interlocks for the purpose of personnel protection, as explained on page 7.

• Interlocks intended for the purpose of protecting the machine and its control components.

There are other locations for interlocks that, when opened, prevent all machine functions. Examples of these types of interlocks are safety block

electrical cut-off systems, lubricating systems, die protection equipment, and tonnage monitoring systems.

Be sure to connect the various electrical interlocks to the proper terminals, in the control box, according to the machine wiring schematics. If your

schematics do not include these electrical interlocks, please send this information to the factory and they can be added to your drawings. There is an

additional charge for this service.

SECTION 2—INTRODUCTION

Overview of Motion and Settings

The redundant inputs are used by both processors to control the operation of the press. When the actuating means is depressed, and the primary

safeguard interlock conditions are met, the processors turn on their appropriate relays (SSR1 and SSR2). The dual solenoid valve is energized

sending air to the clutch and brake. The crankshaft is engaged to the flywheel drive and the brake is released allowing the ram to move. Within

the motion reference time window, the microprocessors must see a voltage signal from the DC tachometer in the resolver/pulser assembly that

represents motion or a motion fault is generated. If the actuating means is released prior to the auto up (holding) angle, the press ram movement

will stop. The stroke can be finished by depressing the actuating means again.

For brake monitoring, the control starts a timer when the relays and solenoids are deenergized. This timer stops when the motion from the

tachometer in the resolver/pulser has stopped. The stop-time value is then compared to the brake stop-time setpoint. If the stop time exceeds this

setting, a brake fault message is displayed. The reason for the increased stop time should be investigated and corrected before operating the press

again. (See pages 46 - 48 for programming the brake monitor.)

Sequence of Operation

This sequence of operation applies to all standard modes provided with the SSC-1500 Press Control.

OFF

The press is inoperable in this mode of operation. The OFF position cannot be used solely as the lockout/tagout means. To use any of the following

modes of operation, turn the mode selector switch from OFF to the appropriate position.

TWO-HAND INCH

To use Inch, the mode selector switch must be set to INCH, and the actuating means selector switch must be set to HAND.

Two-Hand Inch is a mode of operation in which the ram travels as long as the operator(s) maintains actuation of the palm buttons. Each time the

buttons are released, the ram will stop. If the palm buttons are held depressed, the maximum amount of crankshaft travel the control will allow is

approximately 220°.

If Timed Inch is turned on, the clutch will engage and the ram will move only for a set amount of time programmed in to the control, even if the

palm buttons are held depressed. See pages 56 - 57 of this installation manual for Timed Inch programming information.

The Inch mode of operation is used for die setup, tool setup, and maintenance only. It is not intended for use

during production operations.

TWO-HAND SINGLE STROKE

To use Two-Hand Single Stroke, the mode selector switch must be set to SINGLE, and the actuating means selector switch must be set to HAND.

Two-Hand Single Stroke is a mode of operation in which the ram makes one complete stroke or cycle upon actuation of the palm buttons. The palm

buttons must be held depressed during the die-closing portion of the stroke. Once the ram passes this part of the stroke, the palm buttons can be

released and the ram will automatically return to the top. If the palm buttons are released during the die-closing portion of the stroke, the ram will
