Battery
The battery pack is connected directly to the main board.
Wiring diagram - see drawing on page 46
Battery chemistry:
NiMH
Design:
PTC - protected against short circuit
Melt fuse - operating at 72 C
NTC - temperature measurement
The battery pack includes a circuit board with:
* Diodes
* Battery under voltage control - disconnects the battery
from the electronics when the battery voltage is too
low. This reduces the possibilities of reverse polarity.
* ID chip - an EEPROM containing information about
the battery pack (Remaining capacity, etc.)
To get (read) correct remaining capacity, the battery must be
fully charged before turning the transponder ON.

proposed operation.
2 Before deployment, perform a visual inspection of the
transponder.
- The Vent screw and the Pressure relief valve must
be closed.
- The Charger connector must be fitted with a
dummy plug.
- The Signal connector must be fitted with an
external cable or a dummy plug.
3 Perform a functional check to ensure it will operate
correctly once it has been positioned on the seabed.
- Ensure the transponder replies to the correct
interrogation frequency.
The functional check can be performed as follows:
Transponder on deck – use TTC for cNODE® transponders.

Recovery checks
1 After recovery switch the unit OFF.
2 Wash the unit thoroughly in warm fresh water to dissolve
any salt deposits and clean off any sand or silt.
3 As an extra precaution, it is recommended that the unit is
left to soak in fresh water to allow salt to dissolve and
diffuse from hard-to-reach areas, such as crevices around
O-rings, and between mating parts.
- Leave the unit to soak for 24 hours, or as long as
practical conditions allow.
Deployment and operation
331869/D 29
If a rechargeable unit is to be re-deployed imminently, put the
unit on charge.
Vent screw
The vent screw is used when charging the battery, to prevent
build-up of gases inside the cNODE® Mini. The vent screw can
be opened by hand, or use a suitable screwdriver.
Pressure relief valve
The ON/OFF switch also acts as a pressure relief valve. The
ON/OFF switch has two dual O-rings and work as follows:
One O-ring will seal only when the switch is pressed fully
into its seat.
The other O-ring will seal, even with the switch pushed
approximately 2 mm outwards.
If the switch rest in a not fully home position, or they feel
springy when pushed in place, it means there is some
over-pressure inside the cNODE® Mini.
If the pressure becomes too big, the valve will vent. When the
pressure has been relieved, the switch can be pushed back into
position.

How to charge the battery
The battery is charged inside the cNODE® Mini. This is
connected with some risk, so please read the information below,
and follow the charge procedure carefully.
Warning When you are charging the battery ensure the following: - Good ventilation and stable temperature.
- The transponder is not covered. - No open fire, sparks or smoking in the area.
Before you start charging
NiMH batteries can generate some hydrogen and oxygen gas,
the amount depending on certain conditions. Most often this
generation occurs during charging. To prevent build-up of
gasses inside the cNODE® Mini, there are 2 countermeasures.
1 Vent screw.
Caution The vent screw must be open during charging.
a Unscrew the vent screw until you feel some resistance
(a nylon washer is forced against a metal surface).
The O-ring is now visible.
b Hold the cNODE® Mini in an upright position while
you do this, so that any water droplets caught around
the vent screw comes out, rather than going inside the
cNODE® Mini.
c When the charging is complete - tighten the vent screw
by hand only, until you feel a rather sudden resistance.
(an internal axial O-ring hits a metal surface,
compresses 0.3 mm, before 2 metal surfaces meet). The
main flat circular surface of the end cap should now
align with the edge of a semicircular groove that runs
all around the vent screw. This is to visually confirm
that the vent screw has been properly tightened.
Deployment and operation
331869/D 31
2 Safety valve - The ON/OFF switch also acts as a safety
valve.
a In case of a pressure build-up inside the cNODE®
Mini, the safety valve will pop open when the pressure
reaches 0.1-0.2 bar. Under normal conditions this valve
will never operate, as any gas build-up is released
through the manually opened vent screw.
Charge modes
Initialization (charger measures battery status)
Fast charge (charge mode)
Complete charge (Trickle charge – battery fully charged)
Error
Status LEDs
There are three status LEDs on the charger:
A, B and C - for charging of the three battery strings (A, B, C)
individually.
Charge procedure
1 Switch OFF the transponder.
2 Climatize the transponder.
- The battery must have a temperature between 5 C and
40 C. Recommended charging temperature is 25 C.
Note Charging cold batteries (below 10 C) will give less capacity
and shorter service life.
3 Manually vent the transponder - use the vent screw.
4 Connect the charger plug to the cNODE® Mini.
5 Connect Power supply to mains (110 Vac or 220 Vac).
6 Switch on the charger.
- All status LEDs - constant orange light.
7 The charging will start:
Stage 1 - Charger measures the battery status
(Initialization mode):
All status LEDs - constant yellow light.
cNODE® Mini transponder
32 331869/D
- If the battery temperature is out of range, (ref point 2
in this procedure), the charger will show error mode.
* Status LED - flashing orange / green light.
Refer to the Action for Error mode below.
Stage 2 - Fast charge mode
All status LEDs - constant orange light.
Caution Ensure that all (A, B, C) status LEDs show fast charge mode after a few seconds.
- Fast charge - the charger will measure temperature,
voltage and time during this mode.
Stage 3 - Detection of fully charged battery:
All status LEDs - green light with yellow flash for 1
minute.
Methods for detection of fully charged battery:
- Temperature rise (dT/dt)
- maximum time.
When one of these criteria occur, the charger will stop the
fast charge mode.
- If the battery temperature reaches the maximum
temperature (60 C), the charger will show error
mode.
* Status LED - flashing orange / green light.
Refer to the Action for Error mode below.
Action for error mode:
a. Stop charging.
b. Climatize the battery.
Ref to point 2 in the charge procedure on page 31
c Start charging again.
Stage 4 - Completely charged battery and trickle charge
(Complete charge mode)
All status LEDs - constant green light.
Deployment and operation
331869/D 33
Caution Ensure that all (A, B, C) status LEDs show complete mode.
When the battery is fully charged, the charger will start trickle
charge the battery.
Note It is not recommended that the battery is trickle charged for a
long time. It is better to start fast charge again to top the battery
just before operation.
The transponder is now ready for operation!
8 Switch off the charger.
9 Disconnect charger plug from the cNODE® Mini
transponder (external connector).
10 Ensure that the ON / OFF switch and the vent screw are in
closed position.
The recommended temperature range for long-term storage of
the rechargeable battery cells is -20 degrees C to +35 degrees
C*. Stored capacity decreases over time due to the self-
discharge of the rechargeable battery cells.
How to replace the battery pack
The battery is build into the chassis. To replace it, follow the
procedure below:
1 Open the transponder.
Refer to page 19 for details.
2 Disconnect the battery connector. The connector is placed
at the top of the battery.
3 Pull the battery out.
- The battery is fastened to the electronic chassis with
double-faced tape.
4 Assembly is the reverse of dismantling.
cNODE® Mini transponder
34 331869/D
Battery storage
Store the battery in a suitable environment if the unit is not to be
re-deployed in the near future.
The recommended temperature range for long-term storage of
the rechargeable battery cells is -20° C to +30° C*. Stored
capacity decreases over time due to the self-discharge of the
rechargeable battery cells.
Self-discharge is dependent on temperature and the higher the
temperature the greater the self-discharge over time. Long-term
storage has no permanent effect on capacity. Loss in capacity
due to self-discharge is reversible.
*The relative humidity should be < 50%.
Maintenance
331869/D 35
6 MAINTENANCE The following maintenance is normally required:
Washing the unit.
Lubrication of the external connector
Caution Electronic devices can be destroyed by static electricity. It is therefore essential that full protection against static is practised by service engineers.
Although the unit is resistant to mechanical vibration and shock, every effort must be made to avoid careless
handling when the unit is in use or being transported.

O-rings
Whenever the transponder is opened and the O-rings are
exposed, precautions must be taken. This includes keeping the
O-rings and mating surfaces free of dust and debris. If any of the
mentioned surfaces is to be cleaned, it is important to use lint-
free objects. Q-tips must never be used to clean areas anywhere
near an O-ring.
When inserting an O-ring, make sure the surface is clean, and
that it is covered with a thin film of silicone grease.
Preventive maintenance
Preventive maintenance is limited to keeping the unit clean.
Caution Do not use high pressure water as this will damage the transducer face.
Remove all traces of salt and debris.
Before any connectors are disconnected, ensure the
surrounding areas are dry.
Inspect the unit for damage at regular intervals. Pay particular
attention to the transducer surface. This is manufactured of a
synthetic rubber material, and can easily be damaged.
How to open the transponder
Before you open the unit:
1 Wash the unit thoroughly in fresh water, and dry off any
moisture on the outside.
2 Place the transponder horizontally on a flat, clean work-
bench, and support it so it cannot roll off.
3 Disconnect any external cable.
4 Turn OFF the transponder.
Maintenance
331869/D 37
Opening the unit:
The unit is held together by a lock cord inserted (see photo
above) in a groove between the tube and the end cap /
transducer. Access to the cord is via two clearly visible slots at
either end of the transponder tube. The cord is inserted by hand,
and it is removed by picking up the free end visible in one slot,
and pushing the other end (visible in the other slot).
Caution Take care not to use sharp objects that can damage the anodized surface of the aluminium.
Caution Observe the 5 mm orientation peg at either end of the tube. When pulling apart, make sure to keep this
orientation until parts are completely free from each other. Forceful twisting of the parts relative to each other while the internal parts are still mated, will
damage the unit.
5 Remove the retaining cord between the end cap and the
tube, as described above.
6 Carefully pull the end cap from the unit.
- There is a padding between the end cap and the
battery, to secure the battery.
cNODE® Mini transponder
38 331869/D
- Take care when replacing / removing the padding, to
avoid damaging the cables.
7 The end cap is fitted with two guiding pins that fit into
two holes in the electronic chassis.
See drawing on page 45
8 Remove the lock cord between the transducer and the
tube, as described above.
9 Pull the tube from the transducer. Support the transducer
as it is withdrawn.
- All internal parts are now clearly visible and
accessible.
10 Once the O-ring is clear of the housing, the transducer and
electronics chassis may be removed.
Replacement of the transducer
The transducer is a sealed unit and cannot be opened. If the unit
is not working, the whole unit must be replaced.
1 Open the transponder.
Refer to page 36 for details.
Maintenance
331869/D 39
(Cd30111)
2 Remove the transducer from the electronics chassis
(2 fixing screws).
3 Assembly is basically the reverse of dismantling.
Note The transducer part contains a matching transformer.
How to assemble the transponder
Before you start:
1 Inspect the O-rings and backup rings for damage. If in
doubt, or if they have been used for more than one year,
they should be replaced.
2 Place the new bag of silica-gel desiccant into the housing
to absorb any humidity that may have entered the unit
while it was open.
3 Ensure all surfaces, O-rings and backup rings are
completely clean and then wipe a thin film of silica-gel
over the rings and mating surfaces.
Caution Ignoring these recommendations may result in flooding of the transponder unit.
Assembling:
Assembly is the reverse of disassembly.
Handling the O-rings:
cNODE® Mini transponder
40 331869/D
1 Check the condition of the rings and carry out any
necessary replacements.
2 Ensure the O-ring surfaces are clean and free from any
dust, debris or old grease.
3 Lightly grease the rings prior to assembly using Molykote
33 grease or similar.
4 Re-fit the O-rings (see figure below).

2 ringsO- 2 ringsO-
End cap
Retaining cord
(Cd6418)
Lubrication of the subsea connectors
The two 8-pin connectors should be kept free from grit and dirt.
The manufacturer recommends lubricating the pins with:
Molykote 44M silicone based grease.
You must not use silicone based sprays like 5-55, WD-40
or similar. These will degrade the rubber fused around the
metal pins.
Note Use it sparingly; half a match-head dose per contact is
adequate.
