The FTN series offers the option of rotating the head in 90 increments before installation to allow ease of mounting. Giovenzana limit switches can be used in various applications in automation, lift and handling system fields. Operation of these limit switches is achieved by the sliding action of the guard or the moving object deflecting the plunger or lever. For safety applications it s important that upon actuation, the guard or other moving objects should not pass completely over the switch and allow the plunger or lever to return to its original position.

DOUBLE INSULATION Materials of group II, according to IEC 536, are made with double insulation. This consists of doubling the insulation capability by means of an additional divider in order to eliminate any electrical shock risk and avoid the need for any additional protections. A limit switch complies to the specification when all the normally closed contact elements of the switch can be changed, with certainty, to the open position (no flexible link between the moving contacts and the operator of the switch, to which an actuating force is applied). Positive opening doesn t apply to NO contacts. Control switches with positive opening operation can be equipped with either slowbreak or snap action contacts. In order to use different contacts on the same switch, it is necessary to electrically separate them; otherwise only one contact can be used. Every positive opening control switch must be marked on the external housing with the symbol on the left

7 RUBBER ROLLERS ADJUSTABLE LEVERS STRUCTURE DESCRIPTION Different actuators with rubber rollers are available. The customer can choose the most suitable product depending on his needs. For example the lift speed in order to reduce the noise inside the cabin. 8 In switches with revolving lever it is possible to adjust the lever with 8 steps for the whole 360 range. The positive movement transmission is always guaranteed thanks to the particular geometrical coupling between the lever and the revolving shaft. Metal Lever Setting Grooves which engage the lever every 8 are cut in the operation indicator disk to prevent the lever from slipping against the rotary shaft. Head With roller lever models, the direction of the switch head can be varied to anyof the four directions by loosening the roller lever switch screws at the four corners of the head.

14 FTN98: Rope limit switch... Coming soon! OPERATING FORCE FTN SERIES DESCRIPTION The FTN98 switch has been specifically studied to control the lift shaft lights. The norm EN8.0 paragraph states the necessity to have a light switching point next to the working area access and in the machines room. To comply with this standard usually at every floor there are installed lighting points which control a step relay with its considerable costs due to the number of the control points and their wiring. The FTN98 switch itself allows to control the shaft lights through its own wiring, without any need of different lighting points, relays or wiring. INSTALLATION The FTN98 switch is fixed to the superior part of the lift shaft and it s connected to a rope which goes down in the shaft next to the cabin. The rope has to been guided through rings in order to avoid the excessive oscillation caused by the cabin windage. At regular intervals along the rope, usually at every floor, an indicator is fixed to make the rope and its function clearly visible. The last indicator at the end of the rope has a weight inside to keep the rope tight. This way the operator on the cabin roof or in any position along the shaft has the possibility to operate the switch by pulling the pratical indicator or the rope itself.

25 OVERTURNING LEVERS ADJUSTABLE LEVERS STRUCTURE DESCRIPTION It s possible to fasten the lever on switches on straight or reverse side, maintaining the positive coupling. In this way it is possible to obtain two different work plans of the lever. 8 In switches with revolving lever it is possible to adjust the lever with 8 steps for the whole 360 range. The positive movement transmission is always guaranteed thanks to the particular geometrical coupling between the lever and the revolving shaft. Metal Lever Setting Grooves which engage the lever every 8 are cut in the operation indicator disk to prevent the lever from slipping against the rotary shaft. Head With roller lever models, the direction of the switch head can be adjusted to any of the four directions by loosening the roller lever switch screws at the four corners of the head. RUBBER ROLLERS ROTATING HEADS Contact block Different actuators with rubber rollers are available. The customer can choose the most suitable product depending on his needs.

Micro switches dedicated to use in hazardous areas and potentially explosive atmospheres. Ask the dedicated Atex catalogue! POSITIVE OPENING Snapacting blade Micro switches are activated by a springoperated (or snapaction) mechanism. Depressing the actuator triggers the switching operation, with a predefined force and travel. The switching speed itself is a largely indipendent of the speed of actuation. ACTIONING LEVERS It is possible to attach an actioning lever to a snap switch in order to meet the specific requirements of a given application. Doing so usually alters the travel and forces involved in the switching operation, depending on the lenght of the levers. By attaching an appropriate actioning lever, it is possible to increase travel and/or reduce actuating force required. OPERATIONG DEVICE (PLUNGER) Applying force to the actioning lever of a snap switch releases the snap action mechanism, which in turn triggers the switching operation. An additional internal mechanism, made of non resilient parts, forces the opening of NC contacts in case of accidental welding ( overload, short circuit,...) or snap action mechanism failure. Models fitted with this function are particularly suitable for safety related applications according to ISO389 or EN600. To ensure proper functioning of positive opening operation, the operating device must be depressed up to the positive opening position. 77

48 INSTALLATION OF SINGLE SWITCHES WITH SAFETY FUNCTION Use only switches with the symbol. Connect the safety circuit to the NC normally closed contacts (,, 33). Actuate the switch at least up to the positive opening travel. The actuation system must be able to exert a force that is greater than positive opening force. The device must be affixed in compliance with EN ISO 9. OPERATING LEVER REVERSE MOUNTING PLUNGER OR ROLLER LEVER RECCOMENDED APPLICATION Whenever the machine guard is opened and during the whole operating travel, the switch must be pressed directly or trough a rigid connection. Only in this way the positive opening of normally closed NC contacts (,, 33) is guaranteed. 30ϒ 30ϒ 30ϒ In safety applications with only one switch for each guard, the switches must never be activated by a release or through a non rigid connection. According to EN ISO 9 paragraph 5. letter h: the position sensors must not be used as mechanical stop. The actuator must not exceed the maximum travel. The guard must not use the switch head as a mechanical stop. The actuator must not strike directly against the switch head. CONTACT ELEMENTS FTN FTNR FTNG Right Wrong CONTACT ELEMENTS ACTING INDIPENDENTLY (OR ) Is defined, under IEC975/EN6095, the contact element of a device for manual or automatic control circuits where the speed of motion of the contact is virtually independent of the speed of motion of the actuator. Commonly called quick trigger the electrical behavior of these elements means that the contact is in order even in the slow movements of the actuator. These contact elements have position doesn t coincide with the release of drive (differential stroke). Contact in standby Contact activated Apertura positiva RESETTING POSITION SETTING THROUGH 8 STEPS CONTACT ELEMENTS DIRECT ACTING (OR SLOW ACTION) Is defined, under IEC975/EN6095, the contact element of a device for manual or automatic control circuits where speed of movement of the contact depends on the speed of motion of the actuator. FTN FTNR FTNG S RECCOMENDED Right Wrong Contact in standby Contact activated 30ϒ 30ϒ CONTACT BLOCKS CONFIGURATION (according to IEC/EN60975) Contact blocks with terminals must be marked with Zb symbols as shown in the picture. 3 Zb In case of a relatively slow movement of the actuator, CONTACTS ARE RECCOMENDED.
