Safety instructions 1. The installation, initial operation and maintenance should only be carried out by a qualified expert with electrical know-how. 2. Comply with the local and statutory rules and/or the VDE0100. 3. Before electrical connection, check the specifications on the data plate and the technical data of this manual. 4. A fuse must be connected in series to the supply voltage, according to the Standard and Normative documents. 5. Protect the signal contacts of the limit switch against voltage peaks when inductive or capacitive loads are connected. 6. The device may be put into operation only if the electrical connection is correct. To secure the type of protection, the sealing cap and the gasket must be placed correctly and the screw nut of the cable gland has to be fixed and fastened to the cable entry. 7. The rod must not to be struck by the filling stream. 8. For a proper function in side mountings, the device should be installed with a 20 º to 30 º slope from the horizontal onto the silo wall to to facilitate the flow of the material and to prevent the material from remaining over the probe. 9. For a proper function, the device should be installed with a distance of minimum 300 mm from the silo walls. 10. Switch off the power supply, before disconnecting the device. Therefore the bulk material stream should be directed or redirected accordingly, or install a stable deflector or protective cover. Also, this protection roof or cover has to be installed in the detection of minium levels in silos or vessels where heavy loads due to the nature of the materials or the emptying system may damage the rod.

maximum or minimum level of liquid like water, oil, chemical products, etc., in tanks or recipients and the capacitive levels indicators L-E4S are to be used to control the maximum or minimum level of bulk solids in silos or vessels. These indicators have a Stainless Steel rod recovered of PTFE and the devices can have a shaft up to 2.000 mm length depending of the product to control. 1.2 Function The rod must to be exposed to the material. When the level of product reaches the rod, the control unit reverses the signal due to a change of the capacity of the environment. When the product disappear from the detection range, the signal turns to the initial position. These devices have inside the housing a regulation system that allow the adjustment of the sensitivity due to a nut in the electronic module. 1.3 Technical data Manufacturer Talleres Filsa, S.A.U.

OFF: Relay engaged WITHOUT PRODUCT C NO NC 1 A / 250 V AC The green LED is illuminated when the device is connected to the supply. The red LED is illuminated when the relay is engaged. 3.3 Inexpert handling - Ignoring the Safety instructions and the Operating instructions. - Not intended use. - Making changes or handling the controller. - Violation against applicable Law and Standards. - Using of non original parts. 4. Maintenance, servicing and spare parts 4.1 Maintenance - If used correctly, no specific maintenance is required. 4.2 Servicing - Check and review the state of the housing, the rod and the correct commutation of the electrical contact, as well. 4.3 Spare parts - Use original spare parts. - The only possible spare part for these controllers is the electronic module. 5. Storage - Store the controller in a dry and dust-free environment. 6. Disposal - - The controller can be recycled. - The disposal applies to the valid environmental Guidelines according to the location of the carrier and the local manufacturing conditions. Switch off the power supply, before disconnecting the device. 2.2 Mechanical connection The device can be mounted horizontally or vertically depending on the model. The normal installation is by screwing the device onto the deposit wall, with a mounting flange or 2.3 Electrical connection Connection diagram Cable gland with an appropiate support to fix it. - Fasten the cable gland after making the electrical connection. - Fix and fasten the screw nut of the cable glandto ensure the water-tightness. 3. Use 3.1 Commissioning - Put the controller into operation only if the installation and the electrical connection have been done correctly. 3.2 Normal operation - Use the pneumatic controller in its intended application only. - Comply with the specifications - If the controller is damaged, disconnect it immediately. - It is forbidden to make changes to the device.
