Product Description
Product Spesification
Standard design
- duty classification:
- ON-OFF duty, class A according to EN 15714-2 (2S.70..-)
- inching/positioning duty, class B according to EN 15714-2 (2S.73..-)
- modulating duty, class C according to EN 15714-2 (2S.75..-) - protection class IP68 acc. to DIN EN 60529
- corrosivity category C5 acc. to EN 15714-2
- electronic motor protection, automatic phase sequence correction
- start-up current lower than rated current
- line voltage tolerance -10% / +15% in the chosen voltage range, frequency range from 40 to 70 Hz
( full torque for voltage fluctuations between –30 % and +15 %) - permissible ambient temperature: -20°C to +60°C (-4°F to +140°F), (lower / higher temperatures on request)
- electric connection: round plug with screw connection, dust and water-protected when plug withdrawn (double sealed)
- separate mounting of the electronics unit possible
- hand crank/wheel for emergency operation (disconnected during motor operation!)
- valve protection through integrated frequency converter: soft start and speed reduction in the end positions
- adjustable output speed within the selected speed range:
- ECOTRON: in 7 steps (step-up factor 1.4)
- PROFITRON: continuous setting (parameterizable on the display in 2.5% increments between 12.5 - 100% n max.) - output speeds independently adjustable for OPEN, CLOSE, Emergency OPEN and Emergency CLOSE (PROFITRON)
- tripping torques adjustable from 30% (2SA75..-: 50%) to 100% of max. output torque TC max. for OPEN and CLOSE in steps of 10%
- travel dependent cut-off continuously adjustable
- 3 reference torque curves of the valve can be stored (PROFITRON)
- local control with hermetically sealed control knob „Drive Controller“ (optionally lockable)
- operator guidance via display
- external 24 V DC supply for electronics unit possible
- external 24 V DC or 48 V DC supply of the galvanic isolated binary inputs and outputs possible
- galvanic isolation of the analog inputs and outputs (PROFITRON)
- analog actual position value 0/4 – 20mA
- communication with COM-SIPOS via USB and Bluetooth possible (PROFITRON)
- real-time event logging (PROFITRON)
