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.
