4. Principle of operation of battery charger
Battery charger CH-105 allows to charge automatically the accumulator batteries
connected to it (maximum charging current and voltage are set by the user). The battery is
charged by combined method (operation in current stabilization mode in the phase of main
charge with switching to voltage stabilization mode in terminal phase). The example of charging
current and voltage curves of ABC is given on the graphs below (refer to Figure 1):

5. Installation and connection of battery charger
5.1 Installation
ABC is installed in the following sequence:
1. Select and prepare the place for installation of the device so as to ensure free access,
input of cables and termination of their ends. Vertical bulkhead inside the vessel is a convenient
place for installation.
CAUTION! When selecting the place for installation of the device ensure safe
distance to the port-hole so that the water splashes do not penetrate the device when the
port-hole is opened.
ABC shall be installed at a distance at least 1 m away from magnetic compass.

Unicont SPb Ltd Technical Documentation CH-105
Page 6
When ABC is installed in the panel or utility room, take into account the
requirements of Para 7.
2. Properly secure the case of battery charger on the vertical bulkhead with the help of bolts or
self-tapping screws. By the effort of hand check for reliability of its fastening. The information on
installation and overall dimensions of ABC are specified in installation diagram of this OM (refer to
Figure 2);
3. Bring the cables of connected devices to ABC. Use the cable of КМПВ (Э) brand or its
substitutes with the appropriate cross-section of cores. When selecting the cable use information on
diameters of cable leads (Table 2) and maximum dimensions of cross-sections of ABC terminals (Table
3). CAUTION! Before laying and connecting the cables to ABC decide if there is a
requirement to use ABC function on protection of AB from deep discharge and select the
appropriate method of load connection to accumulator battery (refer to Para 5.2.4).

5.2 Connection OF ABC
5.2.1. ABC Connection Procedure
ABC is connected in the following sequence:
1. Remove the device lower cover;
2. Insert the connecting wires of supply circuit, accumulator battery and other connected
devices through the glands located in the lower part of the device case
3. Ground ABC case to the common grounding bus. The grounding bolt is located from
the right side in the lower part of ABC case (Figure 2).
4. Connect the wires of accumulator battery and peripheral equipment to battery
charger terminals in accordance with the diagrams (refer to Paras 5.2.2 and 5.2.3).
5. This paragraph is applicable only to battery charger with marking CH-105
(Table 1). Ensure that the onboard power supply complies with the requirements of this OM
(110 or 220 VAC). From factory ABC is delivered adjusted to supply voltage from network of
220 V 50/60 Hz. If ABC receives power supply from network of 110 V 50/60 Hz, switch the
power unit to power supply from 110 V network. To switch the supply voltage of ABC to
voltage 110 V 50/60 Hz, on power unit set the voltage selector from position "220 V" to position
"110 V" (bottom-upwards). Supply voltage selector is located from the right side of power unit.
6. Connect the power cable to terminals "Input" of ABC (refer to Para. 5.2.5).
CAUTION! For safety of the personnel before connecting the power cable to ABC
make sure that it is completely de-energized.
7. Apply power to ABC with the help of key switch located on the left side of ABC
case. Five seconds after start ABC will be set to operating mode and will display present value
of AB voltage. From the factory ABC is delivered adjusted to charging current and voltage
values of 0.2 А and 25.5 V, respectively (if a battery with operating voltage below 24 V is
connected to ABC, take into consideration that because the value of charging current is small,
the battery charger will not damage the battery since the preset current is comparable with AB
leakage current; however do not leave ABC enabled for a long time without changing the
charging voltage to the appropriate value).
Note! During adjustment of ABC built-in signalling can operate. To disable the sound
signal, press the key "Mute" (refer to Figure 9).
8. In ABC menu set the value of charging current and voltage corresponding to the
connected AB (refer to Para 10).
9. Make sure that ABC operates normally: charging current and voltage do not exceed
the set values and green or yellow light-emitting diode glows (refer to functions of light-emitting
diodes, Table 6).
If the alarm operates, find and eliminate the cause of its operation (refer to the table of
alarms, Table 4).

Safety precautions:
-Do not allow the device to get into water, as well as ingress of water inside the
device.
-When cleaning the device surface do not use organic solvents to exclude damage of
marks and inscriptions.
DO NOT:
-tense the cables connected to ABC;
-connect ABC to networks with parameters different from the ones specified in the
present Manual;
-use the device against its intended use;
-operate faulty device.
5.2.2. Connection of AB to ABC
Connect the cable of accumulator battery to terminal "BATTERY" of ABC.

5.2.3. Connection of Additional Devices to ABC:
Besides the accumulator battery the following devices can be connected to battery
charger:
–thermal sensor DTS-135
–alarm unit AU-106
–remote-control unit UCB-91
Thermal sensor DTS-135 is intended for checking the temperature of charged battery. It
is recommended to use the thermal sensor as part of ABC with helium batteries. Temperature
sensor DTS-135 is connected to terminal "TS" of ABC (refer to Figure 4).
Alarm unit AU-106 is intended to inform the navigator that ABC is in alarm mode by
means of visual and sound signal and it is used when ABC is installed inside the panel or in the
rooms remote from the bridge (refer to Para 7) Alarm unit AU-106 is connected to terminal
"AU-106" of ABC (refer to Figure 4).

Unicont SPb Ltd Technical Documentation CH-105

Remote-control unit UCB-91 is intended for remote control of ABC; it is connected to
control unit through standard interface RS-232. Remote-control unit is connected to terminal
"Remote/Bat_control" of ABC (refer to Figure 4).

ABC.
5.2.4. Connection of Load to ABC
The load can be connected to AB by two methods: directly to AB circuit (refer to
Figure 5) or by means of switched connection through special terminals of ABC (refer to Figure
6).
Direct method of connection is used for loads of any capacity; switched connection is
used for loads with consumption currents not exceeding 30 А.
Method of switched connection enables to use the function of AB protection from deep
discharge (for more details refer to Para 11). ABC function on AB protection from deep
discharge is enabled in ABC menu (refer to Para. 10.2.3.).

Page 10
Note! Voltage of terminal “Output 24VDC” of ABC is directly linked to voltage of AB
connected to terminal "BATTERY" of ABC, i.e. when a battery of 12 V is connected to ABC,
the voltage at terminal “Output 24VDC” equals to 12 V and when a battery of 24 V is connected
to ABC, the voltage at terminal “Output 24VDC” equals to 24 V.
It is recommended not to use ABC as main power supply since the reserved load
connected to AB circuit can be de-energized by ABC despite of availability of power supply line
voltage (for example, in case of short-circuit in AB circuit or in case of strong sagging of
charging voltage when ABC charges deeply discharged battery). To ensure reliable supply by
reserved load, it shall be fed from separate power unit (refer to example in Figure 7).
