brackets (or surface) to which the transmit-
ter and receiver are to be mounted are in
reasonable alignment. The two mounting
holes in the "ears" that bolt to the mounting
surface are slotted to allow the transmitter
and receiver units to be aligned lengthwise
as shown in Figure 3.20b. The front
mounting hole on the section of the
mounting ear that attaches to the transmit-
ter and receiver unit is slotted (the rear hole
is not) to allow pivoting motion to align the
transmitter and receiver in the direction
shown in Figure 3.21b. To achieve best
alignment, first loosen the bolts on the
mounting ears of transmitter and receiver
units that attach the ears to the mounting
brackets or other mounting surface and use
a carpenters level to get them plumb as
shown in Figure 3.20b. When plumb,
tighten mounting ear bolts to the bracket or
surface.
5. Now loosen the mounting ear bolts that
connect the mounting ears to the transmit-
ter and receiver units and pivot transmitter
and receiver back and forth until the green
"CLEAR" light comes on the door of the
receiver unit. Tighten the bolts that hold
the mounting ears to the receiver unit only,
making certain that the green "CLEAR"
light stays on as you do so.
6. Pivot the transmitter clockwise just till
one or more of the red LEDS behind the
acrylic lens on the front of the receiver
come on, indicating that these channels
have lost alignment. Then pivot the
transmitter counterclockwise. The red
channel LEDS should first turn off as the
transmitter is rotated back into alignment,
then turn back on as alignment is lost in the
counterclockwise direction. Again pivot
the transmitter clockwise until the transmit-
ter is located at an angle halfway between
the clockwise and counterclockwise loss of
alignment angles. Tighten the bolts that
connect the mounting ears to the transmit-
ter unit to lock the transmitter into angular
alignment.
7.
Loosen the bolts that connect the
mounting ears to the receiver unit and
repeat the procedure of step 6 with the
receiver to bring the receiver into angular
alignment.
NOTE ! When aligning Black Max units
that have remote segment units, first align
main receiver and transmitter units and
then remote segment receiver and transmit-
ter units. Until both main and remote
segment units are roughly aligned, the
green "CLEAR" lights on the main receiver
door won't come on.
3.8 Functional Checkout of the Link
Lite Black Max Installation and
Machine.
When the installation steps described in
sections 3.3 through 3.7 have been success-
fully completed, a functional checkout of
the operation of the machine and the Link
Lite Black Max(s) must be performed
before placing the machine into produc-
tion, or before beginning installation of
supplementary barriers if necessary.
WARNING! The functional checkout
of the Link Lite Black Max Installation
and the machine on which it is installed
must be performed to verify that the
Black Max is wired into the machine
control to provide on immediate
initiation of stopping action and that
the machine is functioning correctly.
Serious injury or death can result from
hazardous machine action if there are
installation errors or machine
misadjustments or malfunctions.
