1 PROXIMITY CPCITIE SENSORS SC SERIES DELYED MODELS These are capacitive sensors which give an output signal to the load which can have an adjustable time delay up to 15 min. To its energization and deenergization switching in both N.O. and N.C. types. They are supplied only in the Ø 40 model.c. The available ranges of delay are the following: 1 sec. to 1 min sec. to 15 min. trier for adjusting the time has a scale of 0 to 0. These sensors are used in different industrial applications, particularly in the food industry as level controls where a time delay is specifically required without having to install an external timer between the sensor and the load. In order to carry out the adjustment of the sensitivity the timer trier should be zeroed. (See page 64). BCK IEW OF THE DELYED SENSOR - TIME CBLE LODING UNLODING TIME MX. 15 MIN. ERSION C ERSION ERSION R RELY 1 2 ac NPN + PNP + RED dc/ac SPECIFICTIONS OF C - - R ERSIONS SENSORS ERSION C FOR DIRECT OLTGE (4 WIRES) These are amplified D.C. sensors which contain an output amplifier in addition to the oscillator. They are supplied as 4 wires with antiphase outputs in the types NPN and PNP. s standard, this version of sensor is protected against short circuit, absolutely protected against polarity inversion and current peaks created by the disconnection of inductive loads. These sensors can be supplied with power supplies: L - LTP. They are adapted for inputs of prograable controllers. SENSORS ERSION FOR LTERNTING OR DIRECT OLTGE (2 WIRES) These are amplified sensors with two wires which function both in.c. and D.C., these products as well as having an oscillator have a mosfet output amplifier incorporated which is able to open and close a load very quickly. The load which is connected in series with the sensor is passed through by the same residual current that it is supplied by. It is particulay important to pay attention to the low consumption relay, in fact it is important to ensure that: - the required current for the switching of the relay is EQUL to or SUPERIOR to the minimum output current required by the sensor; - the current required of the secure releasing of the relay is SUPERIOR to the residual current of the sensor. If these parameters are not respected there will be an uncertain switching of the relay. Furthermore attention must be given to high impedance input connections of electronic coands as the residual current in the sensor could be sufficient to cause activation. In the closed state a voltage drop can be found this should be taken into account especially when there is a low voltage supply. ll C/DC capacitive sensors are short circuit protected (up to 50 dc and 250 ac). They are also protected against voltage transients coming from the power supply or generated by the load. They are compatible with P.L.C. units. SENSORS ERSION R WITH RELY (5 WIRES) These are amplified sensors which can operate with both C and DC power supplies. The sensors as well as the oscillator and amplifier have incorporated a relay which provides one changeover output contact from 1mp. at 2 ac. The external load can be connected to the or contact of the relay, this solution guarantees greater security in the presence of high loads (up to 1) which is different to sensors with output. Types with instantaneous intervention are available (page 62) or delayed with prograable functions (page 64). CPCITIE SUGGESTION FOR SUPPLYING OLTGE TO CPCITIE SENSORS EXMPLE EXMPLE B C ac Hz ca ac C ac Hz ca ac oltage stabilizer C cc dc C cc dc The supply voltage should be adjusted according to the characteristics of the sensor used. It is recoended to use a trasformer with secondary voltage ac lower than the direct voltage dc required. The secondary voltage ac is found as follows: ac = (dc + 1) : 1,41 The supply voltage dc of the sensor should be filtered with a capacity C at least 470 µf for each 0 used. If the supply voltage dc is high it is recoended to follow the diagram B with a proper voltage stabilizer.

8 DELYED PROGRMMBLE CPCITIE SENSOR SC30P-RE25T TYPE SPECIFICTIONS This proximity sensor belongs to the capacitive sensor family, it supplies a signal to the external load which can be delayed up to min. when any material solid or liquid (water, glass, wood, metal, coffe, powders etc.) come into the sensing area, it is used principally as a level control. This model is completly prograable regarding the delay in energization and de-energization with open or closed output, the sensor does in fact contain a 1 2 chengeover relay. Due to its versatility, prograability and high power output compared to a normal electronic sensor, the stocking of product for the wholesaler is simplified as is the adaptability of the switch to any application. This sensor can be used with the protection housing SCM-R which is of POM and therefore satisfies the most severe abrasion resistance requirements. When used as a level control, this housing allows for the sensor to be substituted whenever required.

The SCM housing is of non toxic material (POM) and is provided with a 1 1/2" GS thread which allows for its installation by using a standard fitting. This type of installation means that the sensor can be rapidly removed for testing without allowing the loss material from the container and protects the sensor from abrasion. Furthemore the use of the housing eliminates to a large degree variation in the sensitivity of the sensor due to deposits of material. It is also available the protection housing for SC40P capacitive sensors.
