3.7.2 Specific Installation Requirements
¾ During the installation you may have mark-up prints. Upon completion of the
installation forward these prints to Control Chief Corporation Application
Engineering so the mark-ups can be incorporated in our drawings and an updated
copy provided.
¾ Locomotive Antenna Installation. Included with the locomotive antenna kit are
detailed installation procedures (P/N 94-85-0-006). Always consider the following
general guidelines:
o The locomotive antenna should be mounted on the cab roof in a vertical
position using the brackets and mounting hardware contained in the kit.
o The locomotive antenna should have a minimum clearance of 36”
between it and any other obstruction mounted on the cab roof. If the
minimum clearance is not possible, then the installation must be tested
to determine if the proximity of obstructions impact system
performance.
o Do not locate antenna in close proximity of any existing UHF/VHF
(voice) antenna(s).
o Pick a location (typically as high as possible) that provides a clear path
between the antenna and the likely transmitter location(s).
o Ensure the antenna cable routing to the receiver / controller unit is such
that the antenna cable will not be cut or damaged by any moving parts.
Note: Two (2) antennas are used on systems with the dual selective control option.
¾ Wiring and Grounding. To avoid EM interference and ensure control system
reliability, specific grounding and shielding practices are required. The following list
provides the minimum guidelines and practices required:
o All coaxial and/or shielded cables are to be grounded at ONE
end only.
The cable shield must be grounded at the end closest to the transmitted
voltage source (i.e. power supply end for transducers not at the
transducer itself).
o All required grounding must be to a common ground plane, which in
turn has a single ground (bonding) connection to earth ground.
o Bonding of the locomotive ground connection must be done using a
copper braid (provided). DO NOT SUBSITUTE.
¾ Remote E-Stop Installation. All externally mounted remote E-Stop enclosures
must be NEMA 4 rated. All remote E-Stop enclosures provided are NEMA 4 or
better. Any field modifications must be done in such a way as to maintain this
rating. All enclosure penetration must be appropriately sealed to prevent
environmental leakage. “Dowty” washer should be used on all cable connectors.
¾ Suppressors Installation Requirements. Another very important requirement, to
minimize EMI, is the installation of suppressors across ALL inductive loads
(solenoid valve and relay/contactor coils). Control Chief will provide all the
appropriate suppressors based on your locomotive design. It is very important to
identify all inductive loads present and to have the appropriate suppressors
installed prior to remote control operation.
