1.3.2 Connection of peripheral devices
1.3.2.1 DTS-135 is installed on rechargeable SB and controls its current tem-
perature. Use DTS-135 only with gel batteries in order to prevent them from «thermal
runaway» in case of their buffer connection. DTS-135 is connected to «TS» terminal,
see Figure 3.
1.3.2.2 AU-106 (AU-206) ensures visual and sound signaling in alarm mode.
AU-106 (AU-206) is used when charger is placed beyond line of sight, where the vessel
is typically controlled from; the units also ensure alarm in case of charger input power
failure.
AU-106 (AU-206) is connected to group of terminals «AU-106», see Figure 3.
Opening (closing) of special charger relay contacts ensures alarm switching on/off:
when alarm is switched on –«Alarm» contacts open, when alarm is switched off –
close.
1.3.2.3 BPC-136 ensures remote control of the Product, present charge or dis-
charge current and voltage, visual and sound signaling in case of transition to alarm
mode.

BPC-136 is connected via standard RS-422 interface; it is connected to «Re-
mote/Bat_control» charger terminal, see Figure 3.
Forced connection of SB to load circuit is carried out by closing contacts of
«Forced start key» terminal, see Figure 3.
Use «Forced start key» together with the Product operation mode №1, see 2.3.1,
and switched connection type, see Figure 5.
Note –If forced SB connection was activated, SB deep discharge protection is
switched off (not depending on the selected operation mode).

Figure 3 –The Product’s connection diagram
1.3.2.4 Load may have direct and switched connection to SB, see Figures 4–5,
respectively.
Direct type of connection is used for loads with consumption current more than
30 А, i.e., power exceeds maximum permissible for the Product.
Switched connection is used for loads with max. consumption current 30 А.
Switched type of connection allows for using SB deep discharge protection
function, see. 2.3.7. Enable (disable) this function in the Product menu, see 2.3.2.
Selected type of connection (direct or switched), as well as switching of connec-
tion type may lead to the limited use of some functions or change the Product’s opera-
tion.
Note –Voltage of the Product «Output 12/24 VDC» terminal, see Figures 3–6,
is directly connected to voltage of SB connected to Product «BATTERY» terminal, see
Figures 3–6; thus, if SB with voltage 12 V is connected to charger, voltage of «Out-
put 12/24 VDC» terminal is 12 V; if SB with voltage 24 V is connected to charger,
voltage of «Output 12/24 VDC» terminal is 24 V.

Figure 5 –Diagram of load to SB switched connection
Do not use the Product with connected SB to power the load (i.e., in buffer
mode), because the load connected to SB circuit may be limited in power output by the
Product (e.g., in case of SC in SB circuit or in case of high drop in charge voltage in
case of deeply discharged SB connection). To provide reliable power supply, power the
load from separate PSU (see Figure 6).

2.3.3 Protection
The Product ensures the following protection:
a) Inductive-capacitive filters (built-in) ensure protection against transient pro-
cesses in power circuit. The filters suppress interference in power circuit ensuring unin-
terruptible operation;
b)Electronic lock of power output ensures protection against current overload
and SC in SB circuit. Once SC or overload occurs, the Product registers the rise of out-
put current and cuts off the power from power output, activating alarm signaling (sound

Automatic battery chargers
CH-105, CH-105-24
17
signal switches on; LED is glowing red; relay contacts open). Power output is switched
off until the reason of overload or SC is removed; once it is done, the lock is automati-
cally released; the Product starts operation and SB is charged in standard mode;
c) Product’s electromechanical switch off from SB ensures protection against
SB reverse polarity connection with alarm signaling (sound signal activates; LED «Er-
ror»is glowing red; relay contacts open). After connection with relevant polarity the
Product automatically connects to SB and continues charging in standard mode;
d)The Product software protects SB against overheating by choosing a charging
mode. To activate this protection, use DTS-135 fastened directly on the SB side.
DTS-135 transmits current SB temperature via communication cable. Once the tempera-
ture increases, the Product automatically decreases charge voltage and current to pre-
vent SB from heating. Alarm is not activated, because charge parameters are changed in
dynamic mode;
e) Order of power phase connection is not essential; the Product will operate
without malfunctions at any order. This type of protection is not supported by alarm and
applied only to CH-105 type.
2.3.4 AU-106 (AU-206) or BPC-136 connection
To ensure alarm signaling, use AU-106 (AU-206) or BPC-136; the units provide
sound and visual signaling of no input power or transition to emergency operation
mode.
Alarm activation of AU-106 (AU-206) is based on dry contacts closing (open-
ing), see 1.3.2.
BPC-136 receives alarm signal from the Product in digital form via RS-422
channel, see 1.3.2.
AU-106 (AU-206) and BPC-136 are powered from rechargeable SB, or, if nec-
essary, from other independent power sources.

memory.
CAUTION! Observe 2.3.1 before switching on SB deep discharge protection.
2.3.6 Display of current SB temperature
The Product may display temperature of rechargeable SB. SB heating is con-
trolled by DTS-135 which is fastened directly on SB.
To activate this function:
In standard operation mode press ▼, the left LCD displays character «t», the
right one –current SB temperature (if DTS-135 is not used, the right LCD
shows «– ––»);
in 10 sec the Product will transfer to main operation mode and LCDs will
display present charge voltage and current strength (press ▼again during displaying
data on SB temperature and the Product will return to standard operation mode).
Note –This function is available if DTS-135 is included in the scope of supply.
2.3.7 SB deep discharge protection

capacitive characteristics and prolongs its lifetime. To activate the function, select menu

Automatic battery chargers
CH-105, CH-105-24
19
item «Pdd» and set «ON»status. If «OFF» status is selected, the function is switched
off.
SB deep discharge protection may be used only if load switched connection is
used, see Figure 5.
If direct connection is used, see Figure 4, protection function shall be switched
off.
SB deep discharge protection activates at residual voltage 19.2 V –for SB 24 V
and 9.6 V –for SB 12 V.
2.3.8 Energy saving mode
Energy saving mode enables to prolong time of load powering from SB. Digital
LCDs (to display present values of charge current and voltage) are switched off in this
mode.
Energy saving mode is activated automatically in case of power mains failure.
To activate LCDs, press «SELECT»button on the casing; they will start dis-
playing within 3 sec.
In case of main power recovery energy saving mode is switched off.
2.3.9 Recommendations on charge current values
To recharge SB, set the current values in compliance with the Manufacturer’s
recommendations (factory parameters) given in SB certificate.
If, for any reason, it is impossible, the Manufacturer recommends to set charge
current values not more than 10 % from SB capacity.
Sample calculation:
At SB capacity (С) –150 А·h, charge current equals С150 * 0.1 = 15 А.
Note –This current value prevents SB from damage in case of overcurrent.
2.3.10 Recommendations on charge voltage values
SB charge voltage shall be set in compliance with SB documentation (factory
charge voltage parameters).
If, for any reason, it is impossible, the Manufacturer recommends to set charge
voltage values 28.4 V for SB with voltage 24.0 V, and 14.2 V for SB with volt-
