Special features Electropneumatic positioner with HART® communication SAM DIGITAL READY Die-cast aluminum or stainless steel housing Attachment to linear actuators according to IEC 60534-6, VDI/VDE 3847, or SAMSON integral attachment Attachment to rotary actuators according to VDI/VDE 3845 Attachment to double-acting actuators with Type 3710 Reversing Amplifier Integrated EXPERTplus diagnostics for control valves Any desired mounting position of the positioner (but not suspended) Simple one-knob, menu-driven operation Easy-to-read display in any mounting position thanks to rotatable reading direction Configurable with a computer over the SSP interface using the TROVIS-VIEW software Variable automatic start-up thanks to four different initialization modes Preset parameters, only values deviating from the standard need to be adjusted Calibrated travel sensor without gears susceptible to wear Sub (substitution) initialization mode allows the positioner to be started up in case of emergency whilst the plant is running without having to change the valve position. All parameters saved in non-volatile EEPROM Two-wire system with small electrical load of 410 Ω Adjustable output pressure limitation Adjustable tight-closing function Automatic zero monitoring Integrated temperature sensor and operating hours counter Two standard programmable position alarms Self-diagnostics Messages as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter DTM file available for integration into FDT frame applications according to specification 1.2 Accessories Pressure gauge TROVIS-VIEW Software (free of charge) Device integration files for engineering tools and systems Options Device compatible with paint Additional equipment: inductive limit contact, solenoid valve, analog position transmitter, external position sensor, leakage sensor, binary input
