Operating instructions (translation) Explosion protection The explosion protection is an option and is indicated by an Ex type plate on the solenoid actuator. The solenoid actuators and integrated solenoid valve controllers conform to explosion protection type "na" category II3G and can be used in zones in which explosive gas, vapour, mist or air mixtures may occur, i.e. in explosion zone 2. The electrical and thermal parameters of the separate variants can be obtained from the respective type plates. The explosion protection applies to operation of the device. For installation, maintenance or repairs, it is imperative that the relevant explosion protection regulations, especially EN 6007914 (VDE 0165 T1), are observed. The electrical installation work must be carried out by, or under the supervision of, a skilled electrician, with additional observance of the relevant national regulations (VDE 0100 in Germany). Prior to installation, the constraints of the device marking must be compared against the envisaged operating conditions to ensure operation is as intended. Basics Valve solenoid actuator combinations are supplied fully assembled and tested as standard. When replacing or changing solenoid actuators, care should be taken that the combination with a UNI valve is approved and the magnet is properly secured to the valve (permissible tightening torque, for example). The devicespecific serial number for unequivocal identification and the year of build can be obtained from the type plate. Solenoid actuators are electrotechnical components that are inoperative without the associated valve and also may not be operated for themselves alone! For outdoor installations always use solenoid actuators with a IP65 rating and a rain cover. Any solenoid actuators showing signs of damage are not to be installed and must be replaced. If the solenoid actuators are subject to external loads of an exceptional kind, additional protective measures are to be taken by the operator, if required. Any undefined or unsuitable changes to the device may negatively influence the explosion protection and in the worst case even render it totally ineffective. UNI devices shall accept no liability for any loss or damage (to the device/over and above this) which have been brought about by change(s) to the device. The same applies for claims under the warranty. Description of the device The solenoid actuator (pot magnet) is used as an actuating unit for valves. Constructionally the actuator consists of a magnet housing (tube, base, magnetic disk and lid), a coil and electronics. Depending on the version, the solenoid actuator may be operated with DC or AC voltage. The version that runs off AC voltage has a builtin rectifier. Therefore when energised, direct current flows through the coils of all types. The solenoid actuators of type MG have a conventional coil with a winding and resulting average sustained pickup forces with average current consumption in continuous operation. The solenoid actuators of type MG A.. and MG A..C on the other hand have two windings on their coil body. One pickup and one holding winding. The TS / RKS builtin valve controller (rudimentary in " A " actuators) switches over after a defined time from the higher pickup power to the lesser holding winding power. In this way, very high pickup forces can be achieved shortterm with simultaneous low current consumption in sustained (holding) operation. Seite 1/ 14 TM 4021 220.100.818
Special condition for safe use 1. Since temperatures higher than 70 C occur at the cable entry and higher than 80 C at the core junction, this equipment must be additionally marked with the higher temperature (label at the cable entry). Only a heatresistant cable may be connected. 2. The solenoid actuators need to be protected against the dangerous consequences of short circuits, earth faults and overloads. A lineside fuse appropriate to the rated current (max. 3xIB acc. to IEC 6012721) is to chosen. A lineside motor circuit breaker with shortcircuit and thermal instantaneous tripping is to be adjusted for the rated current. If the magnet has very low rated currents, fusing with the lowest current value in keeping with the stated IEC standard is sufficient. Protective devices must be of the kind that prevents automatic reconnection under fault conditions. The fusing rated voltage must match or exceed the specified nominal voltage of the solenoid actuator. The breaking capacity of the fuse link must match or exceed the maximum shortcircuit current expected at the place of installation (usually 1500 A). 3. When a silicon (or silicon containing) connection lead is used or if the connecting lead is not scratch proof respectively, this has to be protected from mechanical damage (e.g. inetrrupted tube system with edge protection). 4. A maximum permissible ripple of 20% is valid for all magnets of dcdesign. Electrical connection The diameter range / clamping range of the cable gland must be noted and adhered to. The connection thread of the cable gland amounts up to 30 Watt M16x1,5, from 40 Watt M20 x 1,5.Where a flexible connecting line is used, insulated wireend sleeves with plastic collars conforming to DIN 46228 part 4 are to be used. The voltage supply at the solenoid actuator must lie within the range 15% to +10%. The appropriate circuit diagram can be obtained from the connection diagrams at the end of these operating instructions. To guarantee an IP65 degree of protection, the magnetic housing lid must be refitted carefully. Versions supplied with a connecting cable ex works are ready for use, i.e. the connection compartment does not need to be opened again. The capacitors in the solenoid valve control TS800C must be discharged by an expert. CEIdentification The Council of the European Community passed common directives for the free movement of goods within the European Community, which determine the minimum requirements for safety and health protection. The CEidentification confirms, that the products correspond to the EC directives, i.e. are in agreement with the relevant, especially harmonized standards. Note concerning directive 2014/34/EU (explosion protection directive ATEX 95): The solenoid drives (MG..Xn, MG..A..Xn, MG..A..C..Xn) fulfil the relevant requirements of directive 2014/34/EU; therefore they have the CEidentification as per annex X of the directive. The declaration of conformity is included. Note concerning directive 2014/30/EU (EMVDirective): The solenoid drives fulfil the requirements of the specification to be applied of the product families concerning the industrial sector as well as the sectors of private housing, business and trading, as well as of small businesses. On using of AC and DCvariants the user must provide a suitable mains filter (e.g. Xcapacitor 47 nf) at the mains entrance to attenuate the physically caused linerelated turnoff current of the solenoid. In the sense of the EMVdirectives solenoid drives with driving elements for valves are not regarded as independently operable appliances and are only processed further by expert companies, or respectively installed into a machine. They must not be started up until it was determined that the machine, or respectively, the complete line, corresponds to the regulations of the EMVdirectives. Seite 2/ 14 TM 4021 220.100.818
Note concerning directive 2014/35/EU (LowVoltage Directive): The solenoid drives (MG.., MG..A.., MG..A..C..) were developed, designed and produced in accordance with the standard Electromagnetic Appliances DIN EDV 0580. Thus they will also fulfil the requirements of the low voltage guidelines, which apply to rated voltages from 50 to 1000V AC and from 75 to 1500V DC. Operation 100% ED are permitted even in case of the most unfavourable ambient conditions permissible. Danger! During operation the solenoid drive may get hot. Don t touch, danger of injuries! During operation it must be guaranteed, that neither the maximum permitted ambient temperature or of the fluid nor the load limit (excess voltage) will be exceeded. If necessary the solenoid drive is to be protected against overcharging. All solenoid drives are wired with a varistor. To avoid induced voltage, which may cause damage of the line, the user must provide protective measures in case of necessity which go beyond the installed varistor. Dismounting of the solenoid drive Stop the solenoid drive and cut off voltage supply. Danger! During operation the solenoid drive may get hot. Don t touch, danger of injuries!
