The various functions of this automatic burner control system may be in one or more housings.3.2.2.8multi-burner programming unita programming unit that reacts to signals from control and safety devices, gives control commands, controls thestart-up sequences of the burners, supervises their operation and causes controlled shut-down, and if necessarysafety shut-down and lock-out of the burner or burners. The programming unit follows predetermined sequences ofactions and always operates in conjunction with a flame detector device for each of the burners controlled.According to predetermined sequences it may enable the burner to start up independently, or in combination withother burners, even when one or more burners are already in operation. It supervises their operation independentlyand causes controlled shut-down, safety shut-down and, if appropriate, lock-out of one or all of the burners underits control.3.2.2.9programmethe sequence of control operations determined by the programming unit involving switching on, starting up,supervising and switching off the burner3.2.2.10flame detector devicea device by which the presence of a flame is detected and signalled.It can consist of a flame sensor, an amplifier and a relay for signal transmission. These parts, with the possibleexception of the actual flame sensor, may be assembled in a single housing for use in conjunction with aprogramming unit.3.2.2.11flame signalthe signal given by the flame detector device, normally when the flame sensor senses a flame.3.2.2.12flame simulationa condition that occurs when the flame signal indicates the presence of a flame when in reality no flame is present.

The relative positions of the ignition device and the burner shall be sufficiently well defined to ensuresatisfactory operation of the assembly.When the ignition devices include a permanent pilot, the gas rate of this pilot shall not exceed 0,06 kW for eachburner controlled.

hotplates2) .5.2.8.2.2 of EN 30-1-1:1998 and EN 30-1-1/A1:1999 is replaced by the following :Covered burners and griddlesNon-enclosed covered burners and griddles may be permanent or temporary. When a non-enclosed coveredburner or griddle is temporary, the plate shall be removable and shall be supplied with the appliance.Correct replacement of the removable plate or griddle on the burner for which it is intended shall be easy andobvious. The removable plate or griddle shall be stable when in its correct position.Griddles shall be designed such that any greases produced in cooking cannot spill onto the burner or onto parts notintended for this purpose.5.2.10 Accumulation of unburnt gas in the appliance5.2.12 of EN 30-1-1:1998 and EN 30-1-1/A1:1999 is applicable to parts of the appliance having burners notequipped with automatic burner control systems.
Requirements for parts of the appliance having burners equippedwith automatic burner control systems are given in 5.3.8 of this standard.5.3 Additional requirements for appliances having one or more burners with an automaticburner control system5.3.1 Indirect manually operated burner controls5.3.1.1 GeneralThese controls shall only be used with burners having an automatic burner control system.5.3.1.2 Controls operated by rotation or with a sliding action5.3.1.2.1 GeneralFor a given appliance, all the controls controlling the same type of burners shall be of the same type, i.e.:¾ with the reduced rate, if this exists:either:at the end of the travel or between the closed and full on positions for controls having a single closing direction;or: for rotating controls with two closing directions, positioned such that the same turning direction is used whenturning from the full-on positions to the reduced rate positions;¾ with all controls having two closing directions or with all having the same single closing direction.NOTEThis requirement does apply to combined oven and grill controls.
2)Additional requirements for glass ceramic hotplates are given in prEN 30-1-3:2002.

In addition, the “off” position shall be provided with means complyingwith the requirements of 5.3.1.2.3.If the oven and grill have separate controls, an interlock device shall be incorporated that prevents simultaneousoperation of the oven and grill.5.3.1.3 Touch controlsThe touch controls for a particular burner shall be provided with sufficient touch pads to control the operation of theburner.
These shall be so designed and arranged that the operation of the burner is easy and obvious.The touch controls shall be designed in such a way that at least one of the touch pads only requires a singlemanual action to cause the closure of the gas supply to the burner. The closure of the gas supply shall occur in notmore than 1 s after this manual action.The touch controls shall be so designed that it requires at least two distinct manual actions to initiate the ignitionsequence for the burner.NOTETwo touches of the same touch pad are not considered as two distinct actions.If the thermal function of the burner can be varied, the touch controls shall be so designed that it is easy to increaseor decrease the thermal function.When an oven and grill are situated in the same compartment and the oven or grill burner is not intended to beoperated at the same time as the other burner, or electric heating element, in the compartment, their touch controlsshall be so designed that simultaneous operation is not possible.When an appliance incorporates a hotplate having touch controls, the hotplate shall be so constructed thatinadvertent operation of the touch controls for any hotplate burner is unlikely as a result of spillage of liquids,including that caused by a vessel boiling over, or from a damp cloth being placed on the control panel. Thisrequirement is verified in accordance with the method of test described in 7.4.4.

There shall not be anyrisk of confusion with the control for another energy.Control handles shall be so arranged relative to one another, and with respect to control handles for any otherenergy, that the movement of one handle does not cause inadvertent movement of an adjacent handle.Control handles shall be so designed that they can neither be fitted in the wrong position nor move by themselves.Control handles shall not be interchangeable if this leads to a risk of confusion between the energy controlled, theclosing direction, the operating positions and the “off” position.5.3.2.1.2 MarkingThe requirements of 5.2.2.2 of EN 30-1-1:1998 and EN 30-1-1/A1:1999 are applicable.5.3.2.2 Touch control pads5.3.2.2.1 DesignThe purpose of touch control pads shall be clearly identifiable with respect to the burners they control. There shallnot be any risk of confusion with the control for another energy, nor with other direct and indirect manually operatedburner controls.Touch control pads shall be so arranged relative to one another, with respect to the touch control pads of anotherburner, and with respect to those for any other energy, that the manual operation of one touch pad does not causeinadvertent operation of an adjacent touch pad.Touch control pads shall not be interchangeable if this leads to a risk of confusion between the energy controlled,the closing direction, the correct operating status and the "off" condition.5.3.2.2.2 MarkingThe touch control pad enabling rapid extinction of the burner in accordance with the requirements of 5.3.1.3, shallbe identified by a symbol, or equivalent indication, such that it cannot be confused with any other touch control padfor the burner.Marking and/or other forms of indication (e.g. indicator lights) shall ensure that it is evident whether the burner is inoperation or not.If the thermal function of the burner can be varied, indicators shall be used in such a way as to ensure that thecurrent operating status of the burner, and the means of increasing or decreasing the thermal function, are obvious.5.3.3 Verification of the state of operationThe operation of the burner(s) shall be able to be verified at any time by the user, either by means of visualobservation of the flames, or by other indirect means.In the case of mirrors, or viewing ports, etc., they shall be capable of retaining their optical properties.When an indirect means of signalling is used (e.g. indicator light), the signalling of the existence of a flame shall notbe able to be confused with the signalling of any fault, except for a fault in the functioning of the flame detectoritself, which shall manifest itself by an indication of loss of flame.
