SEVEN actuators

ECOTRON / PROFITRON

Suitable for every process

SEVEN actuators are available both as standard and modulating actuators.

Rotary actuators 2SA7... 9 - 4000 Nm

Part-turn actuators 2SQ7... 75 - 150 Nm

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• electric connection: round plug with screw connection, dust and water-protected when plug withdrawn (double sealed)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)
