4 - INTRODUCTION. - PURPOSE OF THIS MANUAL The purpose of this Manual is to provide the basic information required to carry out repairs on ovens fitted with the SET electronic programmer..2 - ESD - ELECTROSTATIC DISCHARGE AND ITS EFFECT ON THE COMPONENTS The interface for the control unit is not fitted with an internal device to protect against electrostatic discharge. When performing repairs, therefore, the service technician must check for stabilisation of the potential on the oven casing (i.e. discharge any static electricity by touching the oven casing) is order to prevent the possibility of overload and avoid damage to the control unit itself. The same care is necessary when handling control units supplied as spare parts (i.e. not yet fitted to the oven), which must be removed from the protective bag in ESD only after stabilising the potential (i.e. discharging any static electricity) and only then installed in the appliance. Important! : The theory behind the process of electrostatic charge and discharge is not discussed in this Manual, since the tangible effects are considered to be more important. However, the effects are felt frequently when touching a metal handle and feeling the electrostatic discharge in the form of a minor shock. But what happens when stabilisation of the potential takes place with semi-conductor components? (i.e. components on a circuit board, such as integrated circuits, microprocessors etc.)? Stabilisation of the potential takes place across the internal structure of the component. This does not necessarily lead to the immediate destruction of the component; subsequent malfunctions across damaged internal connections may be more harmful, and these occur only as a result of overheating or current overloads. It is true that almost all sensitive semi-conductor components (such as MOS circuits) have been improved by the addition of protective measures, but the internal structures of these components are today smaller than, for example, ten years ago, which tends to increase their sensitivity to the previous levels. Important! Which components are susceptible to damage by static electricity during repairs? All circuit boards featuring control and command accesses (door switches, food probes etc.), bare tracks and microprocessors, as well as any other circuits with free access. Concrete examples: - Programmers connected to the food probe and the door switch. - Programmers whose control processors are accessible (due to their high costs, the protective systems are only partial). - W.O.E.C. control units - S.O.E.C. control units - C.H.E.C. control units - KRONOS control units - R.H.E.A. control units - AVANTGARDE control units - VISION control units.

The various functions are set using a button that scrolls through the functions in sequence to select the one required. The selected function is indicated by lighting the LED corresponding to the symbol for that function. If none of the functions are selected (all the function indicator LEDs are off) the oven will operate in manual mode, because in this case the programmer's internal relay contacts remain closed. N.B.: The lettering and symbols may vary according to the styling and brand. This figure shows an example, for more specific reference please see the instruction manual for your model. 4 - OPERATION This type of S.E.T. (Simple Electronic Timer) programmer fitted to an oven or hob allows various cooking functions to be used. If the programmer is suitably set, the appliance can be turned on and off based on various criteria, as described in the chapter entitled "Use of the programmer". This programmer's main functions are as follows: - Indicates the time by means of a digital display. - Indicates cooking functions on a display. - Semiautomatic timed cooking function by setting a cooking time. - Semiautomatic timed cooking function by setting an end of cooking time. - Automatic cooking function combining an end of cooking time and a cooking time. - Timer function. - Display switch-off function (*). - Start pyrolysis function (**) (*) N.B.: Some more recent versions of this programmer do not have the display switch-off function (see pages 9 and 0). (**) NOTE: This function is only available on certain versions with low voltage relay and power board (see pages 9 and 0). SOI 02.0 FV 7/
