4 Description of the device and operation of the heater

The heater works independently of the vehicle engine.

The heater is supplied with fuel and electricity from the vehicle. The heater wiring diagram is shown in Fig. 192.

The heater is an autonomous heating device that contains: a heater (the main units of the heater are shown in Fig. 193); a fuel pump for supplying fuel to the combustion chamber;

circulation pump (pump) for forced pumping of the working fluid of the cooling system (antifreeze) through the heat exchange system of the heater;

a control unit that controls the above listed devices according to one of a given program;

a wiring harness for connecting the elements of the heater and the vehicle battery.

The heater can operate in one of two programs: "economic" or "normal". The economical program is distinguished by lower power consumption in the "medium", "small" and "cooling" modes.

The principle of operation of the heater is based on the heating of the liquid of the vehicle engine cooling system, which is forcibly pumped through the heat exchange system of the heater.

The gases from the combustion of the fuel mixture in the combustion chamber are used as a heat source. Through the walls of the heat exchanger, heat is transferred to the coolant of the vehicle's engine cooling system.

When the pre-heater is turned on, testing and monitoring of the performance of the pre-heater elements is carried out: flame indicator, temperature and overheating sensors, pump, air blower motor, spark plug, fuel pump and their electrical circuits. In good condition, the ignition process starts. At the same time, the circulation pump (pump) is turned on.

According to a given program, the combustion chamber is pre-purged and the glow plug is heated to the required temperature. Then, according to the same program, fuel and air are supplied. The combustion process begins in the combustion chamber. After the formation of a stable combustion, the glow plug is switched off. The flame is monitored by a flame indicator. All processes during the operation of the heater are controlled by the control unit.

The control unit monitors the coolant temperature and, depending on the coolant temperature, sets the pre-heater operation modes: "full", "medium" or "low". In the "full" mode, according to the "normal" program, the coolant heats up to 70 ° C, according to the "economical" program up to 55 ° C, and when heated above 70 ° C or 55 ° C, respectively, it switches to the "medium" mode. In the "medium" mode according to the "normal" or "economical" programs, the coolant heats up to a temperature of 75 ° C, and when heated above 75 ° C, the heater switches to the "small" mode. In the "low" mode, the coolant heats up to 80 ° C (for both programs), and when heated above 80 ° C, it switches to the "cooling" mode, while the combustion process stops, the pump continues to work and the car interior is heated. When the liquid is cooled below 55 ° C according to the "normal" program, the heater is automatically switched on again to the "full" mode, and according to the "economical" program to the "medium" mode.

The duration of a full cycle of operation is 3 hours or 8 hours, depending on the position of the switch (see section 6) In addition, it is possible to turn off the heater at any time during the cycle. When a command is given to turn off the pre-heater manually or automatically after the pre-set operating time of the pre-heater has expired, the fuel supply is stopped and the combustion chamber is purged with air.

Features of automatic control of heater operation in emergency and abnormal situations:

1) if for some reason the pre-heater did not start, the starting process will automatically repeat. After 2 unsuccessful attempts, the pre-heater is turned off;

2) if during the operation of the pre-heater combustion stops, the pre-heater will turn off;

3) when the heater overheats (for example, the circulation of the coolant is disturbed, an air lock, etc.), the heater is automatically turned off;

4) when the voltage drops below 20V or if the voltage rises above 30V, the pre-heater is turned off.

5) in case of emergency shutdown of the heater, the CONTROL LED will start blinking on the control panel. The number of flashes, after a pause, indicates the type of malfunction. For an explanation of the type of malfunction, see section 8 "Operation manual".

Note. Heating the car's cab is possible only when the cabin heater valve is open and the ground is closed.

5 Heater control unit (CU)

BU provides control of the heater together with the control panel. BU performs the following functions:

a) initial diagnostics (serviceability check) of the heater units at start-up;

b) diagnostics of the heater units during the entire operation;

c) start-up and automatic operation according to the "normal" or "economical" programs (transition to different modes depending on the temperature of the engine coolant);

d) turning off the heater:

at the end of a given cycle (cycle 3 hours or 8 hours);

in case of loss of performance of one of the monitored nodes;

when the parameters go beyond the permissible limits (temperature, voltage and flame failure in the combustion chamber).

6 Control panel with thermostat

The control panel (hereinafter referred to as the panel) is intended for use as part of the 14TC-10 heater as a device providing manual control of the heater. The remote control is intended for:

starting and stopping the heater in manual mode;

installation of work programs: normal or economical;

setting the duration of the heater operation (3 hours or 8 hours);

cab heater fan control;

showing the state of the pre-heater (works, does not work or does not work due to a malfunction).

6.1 The device of the control panel and work with it.

On the front panel of the control panel there are three key switches (pos. 1, 2 and 3), a LED (pos. 4) and a thermostat knob (pos. 5) see Fig. 194.

Rice. 194 Front panel of the control panel

6.1.1 Switches are designed to execute the following commands:

switch pos. 1 (backlit) is used to start (position "|") and turn off the heater (position "O");

switch pos. 2 is used to set the program of work:

a) normal (lower position of the switch);

b) economical (upper position of the switch);

switch position 3 is used to set the operating time of the pre-heater for 3 hours (on the front surface of the control panel it is marked with a symbol 3) or 8 hours (on the front surface of the control panel it is marked with a sign 8).

The position of the switches pos. 2 and 3 can be any; they can be switched during the operation of the heater, i.e. you can change the program of work and the duration of the work. The duration of work after switching will be equal to the time, taking into account the worked.

For example, if you switch from the set time 8 hours to a duration of 3 hours, and the pre-heater has been running for 4 hours before switching, the pre-heater will turn off;

thermostat knob pos. 5 is used to control the cab heater fan (provided that the coolant temperature is more than 55 ° C, and the interior heater switch on the panel in the cab is in the "OFF" position and the vehicle weight is on) as follows:

1) when the thermostat knob is set to the extreme left position, the cab heater fan will be turned off;

2) when the thermostat knob is set to the extreme right position, the cab heater fan will operate continuously;

3) when the thermostat knob is installed between the extreme positions, the fan will turn on cyclically. Cycle duration is 10 minutes.

For example, if the knob is set in such a position that the heater fan will work for 4 minutes, then only after 6 minutes it will turn on again for 4 minutes, etc. Thus, it will work until the position of the thermostat knob is changed or until the heater is turned off. After each change in the position of the thermostat knob (between the extreme positions), the next activation of the cab heater fan will occur in the interval from 2 to 8 minutes.

6.1.2 LED pos. 4 indicates the heater status:

-lit - when the heater is in operation;

- blinking - in case of malfunction (emergency). The number of flashes after the pause corresponds to the fault code (see Table 26).

- does not light up - when the heater is not working.

Attention. To re-enable the heater after its automatic shutdown, the switch pos. 1 must be moved to position "O" and not earlier than 2 seconds later to position "I".

7.1 Malfunctions that can be rectified on our own. The heater does not start after switching on, while it is necessary:

Check the presence of fuel in the tank. Check fuses:

o the "ON / OFF" button when turned on on the remote control does not light up - 5 A;

the heater does not start - 25 A;

o the cab heater fan does not work - 8 A.

7.2 All other malfunctions of the pre-heater are automatically indicated by the flashing of the LED on the control panel.

7.3 Typical heater malfunctions and the procedure for their elimination see section 8.

7.4 In case of all malfunctions arising during operation, except for those specified in clause 7.1, it is necessary to contact the repair shop.

8 Malfunctions of elements of the heater control system

8.1 Troubleshooting should be started with checking the contacts of the connectors of the tested circuits, see Table 25, according to the wiring diagram in Fig. 192.

The output signal and voltage are linear with temperature (0 ° C corresponds to 2.73 V and with a 1 ° C increase in temperature, the output signal increases by 10 mV). Check sensor and replace if necessary.

By simple on the block of the temperature sensor, we measure the voltage:
0 = 2,73
+20 = 2.93 volts
+40 = 3,13

... field-effect transistors. in key mode. it is necessary that the appropriate voltage be applied to the gate, and when the onboard voltage drops to 18 and sometimes to 16! volts, then this is catastrophically small, the key goes into linear mode.

... and in the supercharger circuitry, additional circuits
Those buying a supercharger now will have built-in protection against this, but the control unit will be with the old software.

There are 4 screws, you do not need to remove 2 min max and dismantle anything.

And if someone is dissatisfied with the criticism, then I previously noted this company as successful, which managed to create its own product and squeeze foreign competitors, but in this case they have a real jamb and mistakes need to be recognized and corrected, and not thrown customers, it ends badly for the company ...

Removal from machine to machine is not covered by the warranty.
repair can be, but it must be guaranteed in this case and the costs of replacing parts recognized as defective in this case, the manufacturer will have to pay to dealers as far as I understand. but then there should be a massive review for the given details.

and it is necessary to solve this issue not somewhere in the wilds of the droma forum in a private way, but at least by writing a letter to technical support to the official contacts of the manufacturer.

Those. Can't re-solder without complete disassembly?

Definitely a jamb of the structure, voltage drops in the machine are inevitable. And not just a jamb of a design, but a choice of strategy: the production of these engines has been built. Then write in the instructions: before turning on the starter, the pzh must be turned off. Although it burned out just when the pzd itself was turned off, it seems to me that the refusal was provoked by the control unit itself in the purge phase. Then the next time I just didn’t turn on.

By the way, about balancing, no balancing is felt, the vibration is decent.

The 14TC-10 liquid pre-starting diesel heater is designed to warm up an engine with an antifreeze cooling system prior to its direct start at an air temperature of 0 ° to -45 ° C. Works autonomously, powered by electricity from the car itself. It can also operate on diesel fuel, taking it from the tank or from an additional tank, which is included in the PR kit.

Since modification 14 TC 10 has practically no structural differences from other pre-heaters, its technological characteristics also have static indicators. Thermal conductivity is equal to the following parameters:

maximum mode - 15.5 kW;
average - 9 kW;
minimum - 4 kW.

These indicators are achieved with a fuel consumption of 0.5 to 2 liters. The device PZhD 14TS 10 from 24V operates on diesel fuel in accordance with GOST 305. Antifreeze or antifreeze can be used as a coolant, which is used in the cooling system. As for the power consumption, the following indicators should not be exceeded:

full mode - 132 W;
average - 101 W;
minimum - 77 W;
during cooling - 47 W.

One working cycle lasts 3-8 hours with manual start mode.

The diesel pre-heater 14TC 10 is an autonomous equipment, therefore it functions independently of the main motor of the car. Power is supplied directly from the vehicle.

Heater circuit Teplostar 14TS-10

The package includes the following items:

PZhD engine;
fuel pop for pumping the fuel mixture into the combustion chamber;
circulation pump, which forcibly pumps antifreeze or antifreeze through the cooling system and heat exchanger;

At the time of starting the engine preheater, testing and control of all processes of functioning of the constituent elements is carried out:

fire indicator;
temperature controller;
water pump;
electronic motor for air heater;
fuel pump;
candles and wiring.

If connected correctly, during start-up, ignition occurs, at the same time the circulation pump is activated. The electrical circuit provides 2 main modes of operation:

According to the selected program, a certain amount of fuel is taken from the tank, then the combustion chambers are blown and heated to a predetermined value. The duration of the full cycle of operation in the economy mode is 8 hours, according to the pre-start program - 3 hours. The owner has the ability to stop the operation of the device at any convenient moment.If you turn off the device yourself or after a specified period of time, the fuel supply valve closes and the combustion chamber is blown with clean air.
