Specific Installation Requirements
¾ During the installation you may have to 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. Always consider the following general guidelines:
o The locomotive antenna should be mounted on the cab roof in a vertical position
using the magnet mount hardware provided in the accessories 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.
.
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.
