Hydrophone cable information:

- Black = break

- Red = short circuit

- Yellow = OK

Frequency spectrum - for frequencies on the 00 - 15 band. Select the desired

band by pressing the respective - or + buttons on the keypad (wait for the

unit to update the display). The graph represents background noise and

signal strength of the frequency band selected.

Information from an inter-

faced GPS or integrated echo

sounder if the unit is con-

nected to a transducer.

The Status display shows

sensor data, signal thresh-

olds and background noise

levels providing an overview

of present hydro-acoustical

conditions and the margin

for reliable signal detection.

Other information displayed

includes cable status, pro-

gram version, and echo

sounder / position informa-

tion if the necessary equip-

ment is connected.

Defines sensors 1 to 3

and keeps track of their

attachment locations to

the net.

AGC - recommended to

be ON. Under favorable

noise conditions manual

gain adjustment may

provide increased

range.

MP filter - reduces

excessive echo return or

interference from other

hydro-acoustic equip-

ment operating on the

configured channel

where the sensor is not

in use.

Max shooting speed - compensation

for doppler shift when shooting the

net. Maximum speed may be limited by

channel separation. Effective only when

the vessel is in motion.

Detection threshold -

increases the DT if false sig-

nals are detected on a chan-

nel where a sensor is in use.

A high DT indicates that

only the strongest signals

will be received. A low DT

may provided a longer range

under favorable conditions.

MPF level - is activated

when the MP Filter is ON.

Reduce the MPF level value

in small steps to increase the

filter ’s effectiveness. Avoid

reducing the level so low that

the sensors’ signals are also

blocked.

Select the channel shown on the sensors’ labels

and/or the visual LED identification signal dis-

played when turned on. Note the sensor configura-

tion for later reference.

Sensor filter:

- OFF = no effect (fastest

update of data)

- Light = average of the

last four pings

- Heavy = average of the

last eight pings

The PI30 must receive at least four

pins when first powered up to gener-

ate data. Should one or two pings be

missing, the predicted value will be

displayed in grey. If the signal is lost,

*.* is displayed.

Calibration - is performed on board the vessel to set the sensors’ reference levels to one meter as follows: Suspend

the sensors over the side of the vessel individually or together at a depth of one meter, the draft plus one meter or the

reference level that is to be defined as one meter. Once the sensors’ depth readings have stabilised, set the Calibration

parameter to YES. Sensor calibration takes one minute and the data will be temporarily displayed as grey during this

time. Once the process is complete, the data will again be displayed in black with updated offset values and a depth

of one meter. Note: Sensors not submerged in saltwater will not be calibrated.

Charging - connect the red and black alligator clamps

to the positive and negative fastening lugs labelled “+”

and “-” respectively. Check that the charging lamp on

the sensor charger is illuminated and that the sensor

being charged blinks every four seconds. If it does

not blink in this manner (indicating charging mode),

the battery will not be fully charged. Note: Never

charge a sensor with wet rope in contact with the

fastening lugs.

A fully depleted sensor (representing about 30 hours

of continuous service) must be charged for at least 16

hours to restore its battery to full capacity. Optimal

charging temperature is from +10ºC to 25ºC. Never

charge sensors at temperatures below freezing.

Warning! The use of chargers not specified by Simrad

may lead to personal injury and/or material damage.

Testing - touch the sea water detector (serial no below

300: touch the cover) and a fastening lug at the same time.

This will cause the sensor to switch ON and identify the

channel it transmits on with a series of blinks (see the

Instruction manual) and begin sending data if it is not

programmed differently.

• If the sensor does not blink when switched ON, it

indicates a depleted battery and should be charged for

a few minutes and tested again. If it blinks and begins to

send data, it should be charged for at least 16 hours.

• If the sensor continues to just blink when switched ON

it indicates a close to empty battery. Charge the sensor for

10 minutes and test. If it resume normal operation, charge

for ~ 16 hours.

• If the sensor repeats the start up blinking sequence with

a four seconds interval, it indicates fault with the depth

cover. Contact your nearest Simrad dealer.

Programming - of sensors

is accomplished using a PC

connected to their charging/

fastening lugs. To program

a sensor both the software,

Simrad number: 889-24037

and a special cable number:

380-204728 are required. The

dealer is normally respon-

sible for programming the

various channel selections

and other functions.

Maintenance - rinse sensors with fresh water to avoid depleting their batteries after use. A saltwater film on the

exterior of a sensor can complete the circuit from the sea water detector to a fastening lug. This phenomenon

may also cause the red LED on the sensor charger not to illuminate when a sensor’s battery is deeply depleted.

To remedy this problem, wash the sensor with fresh water and wait several minutes. The sensor may then be

charged as described under “Charging”.

Sensor 1, 2 or 3 Channel 1 to 30

Other depths - if the sensor

is programmed to start at a

depth of 2 m, it should be

suspended at 3 m during the

calibration procedure. Cali-

brate the sensor as described

and note the offset values.

Reduce the offset values by

2 m after calibration.

The red field shows the

signal level that is over the

detection threshold, DT.

The green field over the

noise reference level shows

the detection threshold, DT.
