LINK Systems Max Presence Sensing Device - Manual (Page 3)

Link Lite Black Max Section 1 - User Requirements
1-2
5. Machine controls must be designed for
"Control Reliability", i.e., so that a single
failure in electrical, pneumatic, or
hydraulic components does not prevent the
normal stopping of machine action when
required but does prevent initiation of
further machine action.
6. The machine must require manual
initiation of action after power is turned
on, after changes in operating modes, and
each time a stop signal is applied to the
control.
7. Where presence sensing devices such
as the Black Max are used to safeguard
part revolution mechanical power presses,
the control system must include a brake
monitor"! See 1910.217(b)(14) of
OSHA's General Industry Standards.
NOTE! Link Systems' engineers will
provide assistance upon request in
evaluating your machine tool as to
compliance with control requirements.
Link Systems can provide control systems
for part revolution mechanical power
presses and mechanical press brakes, and
interface systems for many hydraulic
presses and press brakes that meet OSHA
and ANSI requirements for the use of the
Link Lite Black Max as safeguarding
device. Link Electric and Safety Control
Co. assumes no responsibility when the
Black Max is used on machines with
controls that do not comply with the above
requirements or where controls not
supplied by Link fail in such a manner as
to not stop the machine action when the
Black Max provides a stop signal to the
controls.
1.2. Installation
It is the user's/employer's responsibility to
properly install (or have installed) the Link
Lite Black Max, using qualified installers.
Proper installation of any necessary
supplemental barriers or safety devices, or
alternative safeguarding methods is the
responsibility of the user/employer.
1.3. Use Requirements
1.3.1. Safeguarding Configuration
It is the user's/employer's responsibility to
perform a hazard analysis for every job
performed by a machine or production
system using a Black Max light curtain as
a safety component. The user/employer
must determine and implement a
safeguarding configuration of Black Max
units, any necessary supplemental barriers,
and/or alternative safeguarding
components to enhance personnel safety
on every job performed.
1.3.2. Training
It is the employer's responsibility to train
all setup personnel, operators, maintenance
personnel, and supervisors in all aspects of
the safe setup and use of the production
system for every job performed on the
machine. Training must include the
following items.
1. The required safeguarding
configuration for each job.
WARNING! If machine controls are not
designed to stop hazardous machine action
if a component fails, the control may not
stop the machine action when the Link Lite
Black Max sends a stop signal, with
possible consequent serious injury or death
to personnel.
