Section 2 — Outline,
Mounting, and Installation
Unpacking
Inspect shipping cartons for signs of
damage before opening. Check package
contents against the packing list and
inspect each item for visible damage.
Promptly report damage claims to the
freight handler.
Tools
No special tools are necessary.
Controller Mounting
Outline, mounting, and clearance
dimensions for the CHC 140-1W are
shown in Figure 2-2. Four 10-24 x 1/2-
inch screws are required. Outline,
mounting, and clearance dimensions for
the CHC 140-1R are shown in Figure 2-1.
Location
Locate the controller in an area with
restricted access. Locate it where you can
conveniently view front panel indicators
related to Beacon operation. Access to the
rear of the unit is required during
installation and servicing of a rack-
mounted controller. You can place it
anywhere within 2500 feet of the most
distant Beacon without further
consideration. Consult with the factory if a
greater distance is necessary.
Radio Frequency Interference: Direct
exposure to strong radio frequency (RF)
radiation could damage some of the
components or interfere with proper
performance. Place the unit at an adequate
distance from a powerful RF radiator.
Controller Wiring
Figure 2-5 shows the controller and
photocell wiring in a typical installation.
Only general information for a typical
installation is presented here. Consult
any installation drawings prepared
especially for your site or supplied with
the equipment. The installation
drawings prepared specifically for your
site should take precedence. The
System Controller does not control
power to the Beacons.
Make electrical connections at the terminal
block at the rear of the unit. Be sure to
leave enough slack to permit pulling the
unit out of the rack from the front without
disconnecting the wires when installing an
CHC 140-1R.
Ground the case to the site grounding
system.
Photocell Mounting
Conduit usually supports the photocell.
The socket in the photocell has a threaded
male fitting for ½-inch NPT. Mount the
photocell vertically at the top end of a
vertical length of conduit. The conduit
should fasten to the socket from the
bottom.
Dimensions and details are shown in
Figure 2-3 PEC 510 Photocell Mounting
and Outline.
You may locate the photocell any practical
distance from the controller. Mount the
photocell:
•
With an unobstructed view of the polar
sky.
•
So that direct or reflected sunlight or
artificial lighting does not strike them.
•
Vertically at the top end of a vertical
length of electrical conduit to prevent
water from entering the unit.
