Do-it-yourself repair of the Samara autonomy

In detail: do-it-yourself repair of the Samara autonomy from a real master for the site my.housecope.com.

Autonomous Planar is an air heater developed by Russian specialists and manufactured in Samara. The model range of these car heaters consists of four devices (Planar 2D, Planar 4DM2, Planar 44D, Planar 8DM), each of which is available in two versions - 12 and 24 Volts. Even in severe frosts, such an installation can provide the optimum air temperature in the car. First, we will briefly consider the device and the principle of operation of the heater, and then we will study all the Planar errors (fault codes) and their decoding.

Autonomous heaters "Planar" are equipped with a power regulator and a timer. The installation can work autonomously at all stages. Electronics starts ignition only if the various components are in good condition and the required conditions are met. Therefore, you should not worry about the safety of using the device.

The main components of the Planar autonomy:

  • block with control panel;
  • a heating element;
  • fuel pump.

The heaters of this manufacturer work on the principle of supplying outside air to the heating compartment. During the combustion of fuel, energy is released that heats this air. Only after that hot air is supplied to the interior of the vehicle.

To select the optimal power, a special regulator is used with the possibility of fixing in a given position. After the user selects the optimal operating mode, the heater will independently maintain the set temperature.

The basic principle of operation of the Planar autonomy:

  1. Purge of the combustion chamber.
  2. Heating the glow plugs to the required temperature.
  3. Supply of the optimal ratio of air and fuel to the working chamber.
  4. Combustion of the air-fuel mixture.
  5. Turning off the candle after stabilization of the temperature mode selected by the user.

We decided to publish the Planar autonomous fault codes in the form of four tables. Before each of them, a specific model of the heater is indicated, which will help you understand what the problem is in your case.

The air heating device Planar, produced in Samara, is very popular. If there is not enough heat in the car, it is an indispensable assistant, even in the most severe winter domestic weather. In the cabin of a small passenger model or a spacious van, the driver and passengers become as comfortable as possible in a short time period.

The operation of the device is based on a simple principle - drawing the surrounding air masses into the heating chamber. When fuel burns, heat energy is released. It is sent to heat the air, which then enters the interior of the cabin.

One of the advantages that a planar heater has is the ability to adjust the heating power. To do this, the device has a special knob on the regulator, which is easily rotated and set to the desired position.

Having set the desired power value, there is no need to interfere with the further operation of the device. It will be controlled automatically:

  • When the temperature drops to a critical minimum, the Planar turns on
  • A constant increase in heat inside the cabin will gradually reduce power, reducing the supply of warm air

The Planar heater device includes not only a power regulator in the form of a rotary knob, but also a timer. The latter is necessary in order to turn off the installation after a long work.

The device is designed in such a way as to make the work autonomous in all aspects. Automation also monitors the current state of each work item located inside. The ignition process starts only when the control element makes sure that all nodes are in good condition. This achieves a very high level of safety during operation.

The workflow can be described in more detail as follows:

  • The combustion chamber is vented first.
  • The glow plugs are then heated to the desired temperature.
  • The necessary portions of air and fuel are supplied inside the combustion chamber
  • Direct combustion takes place
  • The candle maintains it until the process stabilizes, after which it turns off

To ensure that the resulting flame remains within the normal range, it is controlled by an appropriate indicator. If the temperature limit is exceeded, the control unit will stop burning.

Despite the high level of automation, turning off the device is supported in manual mode. The combustion chamber begins to ventilate. The fuel supply is completely cut off.
