6.
Plug in the charger to a 110-240 V AC 50-60 Hz socket.
7.
If you have the multi-charger, turn the power switch to the
ON
position.
The power switch lights on. If not, check the AC power cord connection.
8.
Wait for the battery to charge: standard charging cycle takes 8 to 12 hours. A fast charge
configuration allows a 70 % charge in 1 hour and full charge in 4 hours.
9.
Look at the LED(s) on the charger box to know the charge status. For the multi-charger, there is
a LED for each sensor charging cable. The charge status are:
•
Green LED: > 90 %
•
Orange LED: from 70 % to 90 %
•
Red LED: < 70 %
Note:
If the sensor is in configuration mode, it will begin to charge after 10 minutes. As
long as it is in configuration mode, the charger's LED remains red, whatever the charge
level.
10.
Make sure to disconnect the charger from the sensor when you switch off the charger or
vessel's power supply. If not, the contact of the charger's pins with the shoulder bolts switches
on the sensor, that will run until discharged.
Results
Once charged, the operational life time can be up to approximately 75 hours.
The operational life time depends especially on the uplink power of the sensor, but also on the
sounding range, uplink frequency and options activated.
Maintenance
Read this section to learn best practices for maintaining the sensor.
Only an approved Marport dealer can access the internal unit. Warranty will become void if anyone
other than an approved dealer tries to do internal maintenance duties on the sensor.
CAUTION:
Never remove shoulder bolts directly from the end cap (black part). Shoulder
bolts are attached to cables and trying to remove them will damage the cables.
CAUTION:
Always inspect and correctly install all the o-ring seals inside the sensor when
doing internal maintenance duties. If o-ring seals are worn out, missing or incorrectly
installed, sensor may be flooded.
