General information:

The ignition controller 3640.3734 is purposed for operation in breakerless ignition systems of automobiles VAZ - 2108, VAZ - 2109, «Tavria» and others including the automobiles of foreign production equipped by analogous ignition systems with the Hall effect sensor.

The ignition controller operates together with the ignition coil 27.3705 and ignition allocator 40.3706, 53.3706 or others with analogous parameters. At the expense of the increased current it has an increased energy of a spark formation that improves the engine start in cold time and improves the engine operation at bad fuel.

On the contact №7 is stipulated the presence of an output low-voltage control signal for systems of electrical equipment with an electronic tachometer or with other devices.

Operation with the disconnected battery or at its failure is not permited. A spark formation (even a short-lived one) without the interference supression resistor (located in the allocator) is not permited. In this mode is possible an irreversible damage of the control diagram which at the further operation will lead to overheating and failure of the ignition controller. For the same reason it is not permited to check the working ability of the ignition controller on the test stands that are made without taking into account the requirements over correspondence of vehicle ignition system to the scheme.

According to requirements to ignition systems, ignition controller ensures Hall sensor protection* against overvoltage by stabilization of voltage fed to the sensor.

The ignition controller is produced in a single climatic design U2.1 in accordance with GOST 15150 for internal market and for export. The ignition controller is designed on a single-wire power circuit in which the negative output of the supply voltage is connected to the vehicle housing. An operating mode of the ignition controller is S1 in accordance with GOST 3940.

The ignition controller is mounted on a stipulated for it place in the vehicle with the help of standard fastenings and a standard plug, thus it is necessary to ensure reliable contact between the radiator of ignition controller and the vehicle housing.

The warranty period of exploitation is 3 years from the date of commissioning or from the date of sale in retail commercial network. The warranty obligations of the manufacturer are valid during 4 years from the date of the item production.
