An overboard lanyard (vinyl-covered stainless
steel cable) is used to secure the sensor/pivot mount
to an eyelet on the PCU unit mounting plate prior to
installation or removal. The overboard lanyard and
associated safety procedures will prevent accidental
over-the-side loss or severe damage (fall to a lower
deck) during installation or removal.
INSTALLATION
Two mounting locations are to be established for
each AN/KAS-1 (fig. 2-12). Each location should be
carefully chosen to ensure that it has a wide field of
view (the view as wide as possible, and not blocked
by other hardware). Care must be taken to avoid
interference with other ships' equipment. Locations
already selected for the Mk 37 night vision sight
(NVS) are usually excellent. When possible, the
mounting locations should be high on the ship, such
as the signal bridge or pilothouse bridge wings. The
locations must be accessible to sound-powered
headphones.
The PCU mounting plate installation requires
separation distance between the sensor unit and the
PCU, and between the PCU and the deck when the
PCU is mounted near the AN/KAS-1. These
separation distances are necessary to ensure that the
power cable will be neither too short nor too long and
thereby create entanglement.
MAINTENANCE
The AN/KAS-1 has been designed for minimum
maintenance. Scheduled maintenance procedures will
be detailed on the MRC. Corrective maintenance
consists of removal and replacement of the sensor/
pivot unit or the PCU when a failure occurs. The
failure will be handled on a repair-and-return basis and
does not require a requisition for replacement.
TRAINING
Each AN/KAS-1 received will have a complete
training package. This training should be incorporated
into the Signalman Personnel Qualification Standards
(PQS).
OPTICAL EQUIPMENT
LEARNING OBJECTIVES: Identify optical
equipment. List procedures for the operation,
maintenance, and handling of optical
equipment.
