Control Unit.

The control unit is the central component of the heater and ensures normal functioning of the heater and control of burning process.

Early modifications of Thermo 230, 300, 350 heaters are equipped with the SG 1572 control unit, modern – the SG 1572D control unit with a possibility of self-diagnostics. The SG1572 control unit can be replaced with SG 1572D.

Mode of the additional heater (only SG 1572D control unit).

If the heater is connected to the plug +61 (operation of the engine), and on this plug tension moves, he works in the mode of the additional heater. The lower threshold of temperature at the same time is higher, than in the normal mode (the mode of the independent heater) and automatically "moves" above or lower depending on operating time of a torch (hysteresis adaptation).

Example: After the first adjusting pause the lower threshold of switching corresponds 78o to Page. At decrease in temperature below this threshold the flame is lit. Duration of continuous operation of the heater in the mode of burning has to be 120 sec. If she is more than 120 sec., the lower threshold of switching will be increased on 1o With, at most to 80o Page. If she is less than 120 sec., the lower threshold of switching will be lowered on 1o With, at least to 70o Page.

Blocking of the heater (only at heaters with the SG 1572D control unit).

If turning on of the heater 8 doesn't lead a time in a row because of the same malfunction to his start or in the course of burning the 5th time in a row occurs break of a flame, the control unit blocks the heater; further attempts of start aren't made. Such blocking has higher rank, than emergency shutdown and is removed by repeated turning on of the heater and its disconnection from the car accumulator during a purge after the emergency shutdown happening at the same time.

Emergency shutdown (heaters with the SG 1572D control unit).

If the control unit registers one of the malfunctions provided below, it makes emergency shutdown of the heater. After several emergency shutdowns in a row there is a blocking of the heater. Has the right to remove blocking only the authorized service station "Vebasto". At emergency shutdown the bulb of the indicator of work blinks, giving a malfunction blink-code. The supercharger of air and the circulation pulser are switched-off in 120 sec.

The codes of malfunctions given on the display of the timer or blinking of the indicator of work (only at heaters with the SG 1572D control unit).

If the heater is equipped with the standard timer, then after emergency blocking the malfunction code is given for the display of the timer (the F 09 code isn't given.)

If the heater is equipped as governing body only with the switch, then the code of malfunction is given after shutdown of the heater in the form of blinking of a bulb of the indicator of work on the switch. After 5 short signals long impulses are given – the quantity of these impulses at various malfunctions corresponds to number after a letter F in the table provided above.

After elimination of a cause of defect an exit from the mode of emergency shutdown is made by switching off and repeated turning on of the heater.

Replacement of the SG 1572 control unit by SG 1572D.
As in modern control units essentially new generation of processors is used, the SG 1572 control unit isn't made now and not delivered. At failure of the SG 1572 control unit it needs to be replaced with SG 1572D according to this section.

For re-equipment of Thermo 230, 300, 350 heaters on the SG 1572D control unit enter a set:

• SG 1572D control unit

• high-voltage coil of ignition

• name plate.

ATTENTION! The SG 1572D control unit can be used only with the high-voltage coil of ignition which is included in the package for pereobo-a rudovaniye (with a green cover of plugs). Shtekerny connection has coding.

Re-equipment order:

1 To disconnect and remove the SG 1572 control unit.

2 To disconnect and remove the high-voltage coil of ignition.

3 To install the new high-voltage coil of ignition from a set.

4 To install the SG 1572D control unit.

5 To paste the new name plate over available as the sign of the fact that re-equipment is carried out.

Replacement of the control unit.
Instruction: When replacing the control unit the head of a torch can remain on the place; she opens only for shutdown of electric connections.

Having disassembled the heater, it is necessary to be convinced that electrodes of ignition aren't bent and the nozzle of a nozzle isn't damaged.

Dismantling.

1. To separate all electric connections on the control unit.

2. To open a head of a torch and to separate shtekerny connection.

3. To remove the flame sensor.

4. To remove the supercharger of air.

5. To carefully extend the control unit from a torch head in the direction of her axis.

Installation.

1. To carefully insert the control unit into a torch head in the direction of her axis against the stop.

2. To insert the supercharger of air.

3. To restore all electric connections on the control unit.

4. To insert the flame sensor.

5. To connect the plug.
