step 2. If they are on, have an authorized
person use the RUN/PROGRAM/SELECT
switch to turn them off while leaving any
FIXED BLANKING necessary for the
setup.
2. Check to see if any Black Max sensor
channels are blanked, that no sensor
channels are unnecessarily blanked, and
that, if blanking is used, that the
requirements for safe blanking in section
4.2.4 of this manual are met. If the
requirements of section 4.2.4 are not met,
have any authorized person set up the
safeguarding system to comply with these
requirements.
3. Insert a test rod or bar with a width
equal to the minimum object sensitivity
(M.O.S.) stated on the labels attached to
the Link Lite Black max receiver and
transmitter units into the Black Max
sensing field next to the receiver unit.
Mover the bar slowly from the top to the
bottom of the receiver unit, observing to
see that every receiver channel LED
indicator turns on as the bar blocks its
position in the sensing field, except for
those channels that are blanked. Also,
check to see that the red STOP SIGNAL
LEDS on the front door of the receiver stay
on except in blanked areas. If remote
segment Black Max transmitter and re-
ceiver units (usually mounted horizontally
or at an angle) are used, block each channel
next to the receiver and observe that the
channel indicator turns on and that the
STOP SIGNAL LEDS on the main receiver
unit light up.
4. Repeat step 3 of this procedure with the
test bar passing through the sensing field
next to the transmitter unit.
5. Repeat step 3 of this procedure with the
test bar passing through the sensing field
about half way between the transmitter and
receiver units.
6. Initiate machine action and insert the
test bar into the Black Max sensing field in
the hazardous portion of the cycle or
stroke. The machine should stop with
normal reaction time. (If muting is used,
the machine will not stop in the non-
hazardous portion of the cycle when the
bar is inserted into the sensing field.)
7. Check to make sure that any other
supplemental or alternative safeguarding
components used with the safeguarding
system configuration in addition to the
Black Max safety components are in place
and functioning.
8. Do not operate the machine if any result
or requirement of this "Operator Safety
System Checkout" is not satisfactory.
Immediately notify a supervisor of any
setup or equipment problem and don't run
the machine until the problem is corrected.

WARNING! MACHINE OP-
ERATOR(S) must perform the "Opera-
tor Safety System Checkout" at each
shift change, operator change, and
production setup change to verify
proper safety system operation and use.
Serious injury or death can result from
a machine or production system hazard
that is not properly safeguarded or a
machine that is not functioning cor-
rectly.
