Simrad PI REMOTE - QUICK REFERENCE GUIDE REV B Quick Reference Manual page 2

System confi guration
Sensor configuration: The sensor
must be configured with a unique
sensor number. Select channel number
and update rate according to the
sensor's configuration. Write down the
configuration for future reference.
Status & Receiver: The Interference
filter must be switched on. Set it to level
9 if you have noise problems from other
hydroacoustic sources. Note that with
the filter on, it will influence the signal
spectrum shown in the Status display.
Sensor filter: Switch this filter to Light.
Set it to Heavy only if you experience
excessive noise. Position Off will provide Off Off will provide
raw data and fastest possible response.
Mounting
The Spread and Remote sensors
must be mounted in special
adapters on each trawl door.
These adapters must be installed
aforehand. Detailed information
on how to install the adapters are
provided with the installation kit.
Installation principle
The PI Spread sensor is mounted
on the port door, while the PI
Remote sensor is mounted on
the starboard door. It is essential
that there is a clear line of sight
between the two transverse
communication "eyes" (one on
each sensor), and between the top
of the PI Spread sensor and the
hydrophone on the vessel.
Sacrifi cial water switch
sensor
If the water switch on your
sensor is a sacrificial brass screw,
this screw must be checked every
month. Whenever required due to
wear and tear, the screw must be
replaced. Refer to the operational
procedures in the operator manual.

Numerical presentation
On the PI display, the distance between
the trawl doors is displayed in the numeric
display. If the distance is increasing or
decreasing, this is shown with two arrows
and the variation in meters per second.
When the readings are stable, the digits
are shown in black colour. When the
values are predicted, the digits are grey,
and if the contact is lost, the characters
*** are shown in grey. If the transvere
communication link fails, this is indicated
with the characters ±±± .
