Simrad PI Charger
Purpose
The Simrad PI Charger is an
intelligent battery charger for fast and
secure charging of the PI sensors. The
charger will automatically set up the
correct charging current depending
on the sensor type and the battery
temperature.
Even though the PI Charger is
designed for fast charging of the PI
sensors, it can also charge the PS
sensors,
but only at normal charge
rate.
A “fuel meter” shows the status of
the battery during the charge.
Indicators
(A)
= 12 to 32 Vdc connected
(B)
= “Fuel meter”, the number
of LEDs illuminated shows the
current charging status. A complete
charging cycle is indicated with all
“full” battery. Charging is indicated as
follows:
Fast
: Fast flash
Normal
: Slow flash
Trickle
: On, off every 4 second
(C)
= Battery temperature
indicators during fast charging of PI
sensors:
Green
: Battery
temperature b5
and +40°C. Fast charge is
enabled.
Green
and
Blue
: Battery
temperature between 0
and +5°C. Fast charge is
disabled, normal charge is
used.
Green
and
Red
:
Battery
temperature b
40
and +50°C. Fast charg
disabled, normal charge is
used.
Blue
: Battery temperature
is below 0°C. No charging
takes place.
Red
: Battery temperature is above
+50°C. No charging takes place.
Daily operation
1)
Attach the charging clamps to
the sensor as follows:
Red
clamp: Positive fastening lug (+)
Black
clamp: Negative lug (-)
2)
Ensure that attachment
materials, rope etc. do not short circuit
the charging lugs. This will prevent
charging, and may and cause damage
to the sensor lugs.
Once connected, the charger will
identify whether the sensor connected
can be fast charged or not. The battery
temperature will always be
monitored for a fast charging
sensor. If the sensor can
not be fast charged, the
charger will not display the
battery temperature, and the
temperature LED will be
dark.
3)
Observe the charge
times and temperature
limitations:
Fast charge:
First
approximately one hour for
70% battery capacity, then
approximately three hours to
reach 100% capacity. Once
fully charged, a constant
trickle charge will compensate for self
discharging.
Note that fast charging applies to
PI sensors only!
Normal charge:
16 hours for
full battery capacity. This mode
applies for charging outside specified
temperature range, and for all PS
sensors.
Charging temperature:
For best
results, keep the ambient temperature
b10 and +25°C.
Do not charge sensors in
temperatures above +50°C or below
0°C!

WARNING!
Charging a sensor at sub-
zero temperature might develop
explosive gases representing a
potential danger. Simrad assumes
no liability for improper charging,
or the use of other chargers than
those approved by Simrad.
