The actuator undertakes the basic position with a closed valve. In the case of corresponding units, the basic position corresponds to so-called safety ef-fect ”current-free closed“In the initialisation process, the positioner adjusts to the defined actuator pivoting range. The analog activation is triggered from the control point and effects the pro-portional allocation of the defi ned pivoting angle to the set value (input) signal.In a similar manner, the defi ned pivoting angle is allocated an analog positioning signal.Binary signals are formed additionally at the start and end of the pivoting range. Electrical connection is made at terminal blocks inside the unit. Pneumatic connec-tion is made directly at the external sole-noid valves.• or directly onto actuators type actubar. Solenoid valves are fi tted to standard inter-faces with type-related material.Functional Description:5Operating Instructionsbar-positurn2Pivoting angle10° to 190°Protection Type IP 65Mounting position randomAmbient temperature-20°C to +70°CAmbient humidity10-90%, non-condensingWeight Without valve ca. 0,65 kgVa riant D Mini-valves: ca. 1,0 kg Midi-valves: ca. 1,1 kgVariant S Mini-valves: ca. 1,2 kg Midi-valves: ca. 1,4 kgVariant E Mini-valves: ca. 1,2 kg Midi-valves : ca. 1,4 kg Analog c ontrolsignalEffective direc-tionreversible by sliding switchActuating signal Signal type selectable 4-20 mA, 0-10 V, inverse polarity-protection, proportional to pivoting anglePre-resistor > 1 kOhm at 0-10 V; < 500 Ohm at 20mADead-zone± 2% of nominal pivoting angleTravel s peed Adjustable by t hrottles in solenoid valvesPosition s ignal Signal type selectable 4-20 mA, 0-10 V, nominal, active, inversepolarity protection, proportional pivoting angleResolution < 0,5% of nominal pivoting angleLimit feedback Voltage12-28 VDCSystem Opto-coupler, short-circuit-proof; 1 kOhm series &10 kOhm parallel resistance fittedIndication 3% of nominal pivoting angle b efore initiated endpositionSupply24 VDC (21 bto28 VDC), inverse polarity p rotectionPower Variant D Mini-valves: 1,8 W M idi-valves: 4,2 Wconsumption Variant S Mini-valves: 3,6 W M idi-valves: 7,2 WVariant E Mini-valves: 3,6 W M idi-valves: 7,2 W Terminal strip Clamping range up to 0,75 mm²Cable to P CS7 to 13 mm, 0,5 mm2, random cable lengthBinary inputsignalsON/OFF valves < 10 V for …0“;> 18 V for …1“Operating pres-sure2,5 to8 barAir Quality Filtered air acc. to DIN ISO 8573-1/Class 467Operating Instructionsbar-positurn2Delivery and Unpacking:Pneumatic scheme for positurn2 PN2-D PN2-E (single-acting) PN2-S (double-acting)Please note the unit-specifi c safety descriptions on pages 13 and 14.The unit is dispatched from bar and trans-ported by selected transport companies i.e. parcel services.

This can lead to damage to the vie-wing glass or paintwork.• C lean the housing of the positurn2 with a clean, slightly moistened cloth.• I n the case of hardened-on dirt, use a normal household cleaner according to the instructions on the packaging on the cleaner.Never open the protective co-ver above the delicate electro-nics. This can lead to damage to the unit and the loss of all warranty claims.• T he positurn2 works maintenance-free.
