4 OPERATING INSTRUCTIONS,
REQUIREMENTS, AND PRECAU-
TIONS
IMPORTANT! All setup personnel,
operators, supervisors, maintenance
personnel, and other persons associated
with the care and use of machines or
production systems using Link Lite Black
Max light curtains as safety components
must read (or be provided with the knowl-
edge of) the material in this Operating
Instructions, Requirements and Precautions
section to enhance safety to the fullest
possible extent. OSHA and ANSI stan-
dards make it the employer's responsibility
to train all employees associated with the
setup, operation, and maintenance of the
machine, and to provide supervision to
ensure that employees follow proper setup
and operation procedures.
4.1 Safeguarding System L imitations
and Requirements
Link Lite Black Max light curtains are not
the safety system, but rather are a compo-
nent of the machine safety system. Light
curtains send a stop signal to the control of
a machine when someone of something
blocks their sensing field light. They
depend on other electrical, pneumatic,
mechanical, and/or hydraulic components
of the machine drive system to actually
stop hazardous action when you are in the
sensing field. In some cases, supplemental
barriers or safety devices may be required
in addition to light curtains to protect you
from the machine or production system
hazard(s). Light curtains must be properly
installed, located, and used in conjunction
with any other necessary safety compo-
nents to protect you, in accordance with the
following requirements.
1. Link Lite Black Max light curtain
presence sensing devices are designed and
manufactured to comply with OSHA and
ANSI standards for construction of point of
operation devices. Properly installed,
located, adjusted and used presence
sensing devices enhance personnel safety
by preventing normal initiation of hazard-
ous machine action or by stopping normal
hazardous action in progress if the opera-
tor's (or other's) hand or other body part are
in the sensing field (the plane directly
between the Black Max transmitter and
receiver units as shown in Figure 4.1).

location between main Black Max
transmitter and receiver units when no
blanking is used.
Proper machine preventative maintenance
must be performed to reduce the risk of
accidents that result from failure, wear, or
misadjustment of machine components.
WARNING! No presence sensing
device, including the Link-Lite Black
Max, will protect you from abnormal
hazardous machine action(s) caused by
failure, wear, or misadjustment of
mechanical, hydraulic, pneumatic, or
electrical components of the machine
upon which it is installed. Serious
injury or death may result from such
failures.
