Instruction manual

Simrad PI Remote/Depth
INSTALLATION
The PI Remote/Depth sensor is mounted on the starboard
trawl door using a special adapter. From this position, it will
communicate with a Spread or a Spread/Depth sensor on the port
trawl door, and with the hydrophone beneath the vessel.
Sensor installation
The PI Remote/Depth sensor and the Spread or Spread/Depth
sensors must be mounted in dedicated adapters on each trawl
door. These adapters must be installed beforehand. Detailed
information on how to install the adapters are provided with the
installation kit.
The PI R emote/Depth sensor is mounted on the s
tarboard door,
while the PI Spread (or PI Spread/Depth) sensor is mounted on
the p
ort door.
Note
It is essential that there is a clear line of sight between the two
transverse communication “eyes” (one on each sensor). It is
also important that both the PI Spread (or Spread/Depth) and
the PI Remote/Depth sensors have a clear line of sight to the
hydrophone on the vessel.
The two rubber inserts provided at the bottom of e ach sensor
adapter must not be replaced with any other types or designs.
It is essential that these inserts provide a secure cradle for the
sensors, but they must also allow for free water c irculation to
allow the sensor’s water switch to engage. Also, the design of
the inserts allows sand and mud to flow out when the trawl doors
are pulled up from the water.
Adapter installation
The installation of the sensor adapter is described in the dedicated
instruction manual provided with the adapter. The document can
also be downloaded f rom w
ww.simrad.com.
Note
The adapter used to install the PI Remote/Depth sensor is not the
same as the adapter used for the standard PI Remote sensor.
The PI Remote/Depth sensor uses the same physical housing
as the PI Spread and PI Spread/Depth sensors, but it must be
mounted “upside down” to establish free view between the two
transducers used for the transverse communication.
