Check of serviceability of functioning of system of preheat

The best way of check of a condition of components of system is their replacement on obviously serviceable. Nevertheless, there are some tests which need to be made first of all.

 PERFORMANCE ORDER

  1. Attach the voltmeter or 12-voltnuju a lamp-sampler between a wire of a food of candles накаливания and "weight" (metal of a body or the power unit, - grounding should reliable).
  2. Ask the assistant to include ignition and consider the measuring instrument indication, - pay attention to duration of functioning of a control lamp of preheat on a control panel and compare it to duration of giving of pressure on candles.

At temperature in an impellent compartment 20°С duration of functioning of a control lamp should make 3 with. Temperature decrease involves duration increase, and on the contrary.

If the lamp does not work also a food on candles does not move, a cause of a failure the module of management or its chain электропроводки.6 can be

 PERFORMANCE ORDER

  1. For identification of a faulty candle, give nuts, remove washers and disconnect from candles a wire of a food and the tyre, - on models of last years of release simply enough to disunite contact sockets of candle electroconducting.
  2. Connect an ohmmeter between the central conclusion of a candle and "weight", - the serviceable candle has very low resistance (less than 1 Ohm). If the ohmmeter registers breakage (the infinite indication), hence, the candle is faulty and is subject to replacement. It is alternatively possible to connect a lamp-sampler between a wire of a food and the central conclusion of a candle, - ignition inclusion at a serviceable candle should lead to lamp activation.

At presence near at hand the ampermeter it is possible to measure force of a current proceeding through everyone candle. After the first impulse amplitude 15—20 And the current strength should fall to 12 A.Pri an exit of result of measurement for limits of an admissible range a corresponding candle is subject to replacement.

In the conclusion, a candle it is possible to turn out and check up, being guided by instructions (Removal, check and installation of candles накаливания see).
