AMERITRON RCS-4 - Installation; Operation

INSTALLATION
The relay box may be mounted on a tower leg, mast or
building wall. The mounting hardware furnished will
accept a tubular mast up to | 4” diameter.
If the box is mounted on a building wall discard the “U”
bolt assembly and use two 4” screws to attach the
bracket to the wall.
The relay box must be mounted with the connectors
down. Do not attempt to air seal the relay box. Install
drip loops below the box if the feedlines are brought in
from a higher location. Lightning retarding loops area
recommended precaution on all cables (see illustration).
Relay Box Cable Connections
Connect your antennas to coax connectors numbered 1-4
and note which antenna is connected to cach socket.
Connect a coax lead to the connector marked
“CONTROL CONSOLE.” This lead should be long
enough to altach to the control console.
If contro] power fails, the relay box selects antenna “4”.
It would thus be wise to put the most frequently used
antenna in position 4
Control Console Connections
Locate the RCS-4 control console at a convenient
location on the station operating desk.
The control console supplies 12YV AC and DC control
voltages. It has an internal LA fuse in the transformer
secondary circuit that protects the power supply if a short
circuil occurs in the feedline. Caution must be exercised
when connecting the RCS-4 to prevent damage to station
equipment.
Use coax to connect the “STATION” SO-239
connector to the output connector of your transceiver,
amplifier or tuner. Connect the coaxial line from the
relay box to the “RELAY BOX” SO-239 connector.
DO NOT CONNECT THE “RELAY BOX”
CONNECTOR TO THE STATION. CONNECT IT
TO THE RELAY BOX FEEDLINE ONLY. DO NOT
“HOT SWITCH” THE RELAY BOX WITH POWER
LEVELS OVER 100 WATTS.
THERE SHOULD BE NO _ PIECE OF
EQUIPMENT BETWEEN THE INDOOR AND
OUTDOOR BOX.
OPERATION
Ll. Plug the Sine cord into a 117 VAC outlet.
2. Place the PWR switch in the “ON” position.
3. Rotate the SELECT control and observe the
lights one through four.
The switch positions are numbered on the front of
the control box and a space is provided above each
position so you can pencil in its designation for
each antenna.
GROUNDING
The RCS-4 has small air gaps near each antenna
connector on the printed circuit board to protect against
lightning damage. We strongly recommend the use of
lightning retarding loops in the coaxial cables near the
relay box (see illustration). Remember that lightning
travels through the path of least resistance. Station
ground leads should be solid, large surface arca
conductors. Do not use braided or stranded wire for
the ground leads.. Avoid sharp bends in the ground
leads. Use multiple ground rods and/or radials to
provide the earth termination.
