    1. Application The Magnet-Ex 12 is a device for the detection and testing of magnetic fields for industrial application in areas with an increased risk of explosion in zones 2 and 1, in accordance with directive 1999/92/EC (ATEX 137). 2. Safety information These operating instructions contain information and safety regulations which are to be observed without fail for safe operation in the described conditions. Non-observance of this information and these instructions can have serious consequences or it may violate regulations. Please read these operating instructions carefully before starting to use the unit! In case of any doubt (in the form of translation or printing errors) the German language operating instructions shall apply. 3. Errors and impermissible loading If there is any reason to suspect that the safety of the unit has been impaired, it must be withdrawn from use and removed immediately from the Ex-area. Measures must be taken to prevent it from being restarted accidentally. We recommend that the unit is returned to the manufacturer for inspection. The safety of the unit may be compromised, if, for example: - there is visible damage to the housing. - the unit has been subjected to excessive loads. - the unit has been improperly stored. - the unit has been damaged in transit. - unit markings or inscriptions are illegible. - malfunctions occur. - permitted limit values have been exceeded. 4. Safety regulations Use of this unit assumes that the operator observes the conventional safety regulations and has read the certificate in order to eliminate faulty operation of the unit.

    7. Functional description / operating instructions Please read these operating instructions carefully so that you are familiar with, and are able to use, all features of the Magnet-Ex 12. For your own safety and information please read the instructions on the following pages carefully! 7.1 General The Magnet-Ex 12 can be used to detect quickly and precisely magnetic fields on solenoid valves, spools, trans- formers, relays and flowmeters. The LED of the Magnet-Ex 12 responds to all types of magnetic fields, no matter if the magnetic fields are alternating, direct and permanent fields. The LED responds even if the probe is not in direct contact with a solenoid valve, for example. The built-in test magnet, which is located in the cap of the housing, allows you to run a self-test and to check the battery simultaneously. 7.2 Application Before each use, it is recommended to run a functional test. This can be done by using the test magnet and placing it close to the probe. The LED of the probe should light up. The probe of the Magnet-Ex 12 can then be placed near to a suspected magnetic field of, for example, a solenoid valve. If there is a sufficiently active magnetic field, the probe lights up. The Magnet-Ex 12 detects via the magnetic field if a solenoid valve is working properly. An intrinsically safe mul- timeter can only measure the current or voltage of a valve, but the Magnet-Ex 12 will indicate as to whether or not there is a sufficiently active magnetic field. This way the operator can detect a fault of the valve spool. If the valve does not work properly although the probe has detected a magnetic field, the valve is probably jammed.

    Probe LED indicator Using the test magnet, a self-test is performed. Clip Removable cap with If the probe is placed near test magnet a magnetic field, for example of a solenoid valve, the LED indicator of the probe will light up. 7.3 Battery replacement When the power of the batteries is becoming exhausted, the LED becomes perceptibly darker while the sensor unit still works faultlessly. Use the test magnet, which is located in the cap of the housing of the Magnet-Ex 12, to check the brightness and the proper functioning of the LED. If the LED is becoming darker or does not light up at all, you have to replace the batteries (always outside the Ex-area). Only type-tested batteries are to be used (refer to the table with type-tested batteries under section 6, „Technical specifications“). The use of any other type of batteries is strictly forbidden. In order to replace the batteries, first remove the cap of the housing by unscrewing in an anti-clockwise direction. Replace the batteries. Close the cap of the housing by firmly screwing it in a clockwise direction. - Always replace all batteries simultaneously. - Pay attention to the correct polarity. - P lease ensure that all used batteries are properly disposed of in an environmentally friendly manner. - M ake sure that the cap of the housing has been screwed firmly.
  • Page 7: Repair

    8. Repair Repairs are to be conducted by ecom instruments GmbH or by personnel or service centres authorised by ecom instruments GmbH, because the safety of the unit needs to be tested after repairs are implemented. 9. Disposal Old electrical devices as well as „historical“ old electrical devices from ecom instruments GmbH are supplied for disposal at our expense and disposed of free of charge in accordance with European Directive 2002/96/EC and the German electrical law of 16/03/2005. The costs associated with returning devices to ecom instruments GmbH are to be borne by the sender. In accordance with “Directive 2006/66/EC on batteries and accumulators and waste batteries” we are obligated to provide you with the following information: Your device contains an alkaline battery. Depleted batteries should never be disposed of along with normal or household waste. Old batteries can contain harm- ful substances that are hazardous to health and damaging to the environment. Please return the batteries. Return is free of charge and required by law. Please only dispose of discharged batteries in the designated containers. Note: The battery used in this unit poses a fire hazard and can cause chemical injuries if it is used improperly. Neither the battery nor the battery cells should be opened or disassembled and they should not be burned or exposed to temperatures exceeding 100°C. If the battery needs to be disposed of, it can be removed as described under point (7.3). The disposal regulations specified above are also applicable for old devices. All batteries can be recycled. Precious raw materials such as iron, zinc and nickel can therefore be reused. The symbol has the following meaning: Batteries and rechargeable batteries should not be disposed of along with normal or household waste. 10.
