Operating instructions (translation)
Explosion protection
The solenoid actuators and integrated solenoid valve controllers conform to explosion protection type
"de" category II2G as well as “td” category II2D and can be used in zones in which explosive gas,
vapour, mist, or air and dust mixtures may occur, i.e. in explosion zone 1 and 21. 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 60079-14 (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 device-specific 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 built-in rectifier. Therefore when energised, direct current flows through the coils of all
types. The solenoid actuators of type MG…X 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.X on the other hand have two windings on their coil body. One
pickup and one holding winding. The TS200 / TS900 / TS1500 built-in 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 short-term with simultaneous low
current consumption in sustained (holding) operation.

Solenoid Drive
Series MG…X, MG…-A.X
With - protection for intended use in ex- zone 1
in accordance with 2014/34/EU (ATEX 95)
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 heat-resistant cable may be connected.
2. The solenoid actuators need to be protected against the dangerous consequences of short circuits,
earth faults and overloads. A line-side fuse appropriate to the rated current (max. 3xIB acc. to IEC
60127-2-1) is to chosen. A line-side motor circuit breaker - with short-circuit 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 short-circuit
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 dc-design.
5. The repair and overhaul of the flameproof joint is permitted only after first consulting with Uni-
Geräte.
6. The emergence of explosive atmospheres is to be avoided in the region of the magnetic core and
guide tube.
Electrical connection
The diameter range / clamping range of the cable gland must be noted and adhered to. Where a
flexible connecting line is used, insulated wire-end 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.
CE-Identification
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 CE-identification 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 CE-identification as per annex X of the directive. The declaration
of conformity is included.
Note concerning directive 2014/30/EU (EMV-Directive):
The solenoid drives fulfil the requirements of the specification to be applied of the product families con-
cerning 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 DC-variants the user must provide a suitable mains filter (e.g. X-capacitor 47 nF)
at the mains entrance to attenuate the physically caused line-related turn-off current of the solenoid.
In the sense of the EMV-directives 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 EMV-directives.

Operation
100% ED are permitted even in case of the most unfavourable ambient conditions.
DANGER!
During continuous 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 tempera- ture or
of the fluid nor the load limit (excess voltage) will be exceeded. If necessary the solenoid drive has to
be protected against overcharging. All solenoid drives are wired with a varistor. To avoid induced
voltage, which may cause damage within the installation, the user must possibly provide additional
protective measures, which go beyond the installed varistor.
Dismounting of the solenoid drive
ATTENTION!
Disconnect the circuit before opening or, respectively, removing the
soleno id drive and wait at least 120 minutes.
