TEC 2000 Electronic Actuator • Key Features • proven design of the mechanical part of the actuator which is the fruit of more than 60 years of experience of EIM with electric actuators • ‘’state of art’’ electronic control which is the fruit of more than 25 years of experience for the application of electronics on electric actuators: EIM Controlinc was introduced in 1985. • Patented “absolute” position monitoring system, high range, high resolution, based on Hall-effect sensors, no need of internal batteries to “remember the position” in case of operation without external power supply, no need to replace any battery during actuator life. • Output torque control is based on worm-shaft axial load monitoring: real output torque is monitored in real time, no need of data upload/download in case of logic card replacement or motor replacement/rewound.
TEC 2000 Electronic Actuator Key Features • Quite intuitive non-intrusive setting by means of a really user friendly local interface for full actuator setting, control and diagnostic info access: • very large Local Display (the largest or one of the largest in the market). • complete set-up and menu’ navigation by “Yes/No” questions, without opening the actuator and without need of any battery powered handheld device, • all questions & info are given in plain text (no symbols are displayed) LEDs IrDA Transmitter & Receiver Graphic Display Message Centre(2 lines, 16 characters) Selector Knob Control Knob • Set-up is possible also without external power supply in presence of optional back-up batteries. • Local interface can be mounted in 7-8 different positions on the actuator housing, additionally it can be easily duplicated in two additional remote positions (up to 1,2Km) for comfortable access. • Possibility of setting & control by “Clicker” (an IrDA controller) and via RS-485 (PC/PDA) with also possibility of diagnostic data download, software upload via RS-485 (PC/PDA).
TEC 2000 Remote Display Module Remote Display Module • Duplication of Local Display functions, it is identical • Up to 1.2 km from actuator • Up to two for each actuator • Provides safe, local operations in hazardous areas • Enables positive control of valves from a safe distance in the event of an emergency
TEC 2000 Electronic Actuator Key Features • Double Sealing Protection of the terminal board (when terminal board cover is opened, internals are still sealed), • primary fuses on terminal board (really non intrusive execution), • terminals are clearly visible in all conditions, terminal board can be mounted in 7 different positions on the actuator housing.
TEC 2000 Electronic Actuator Key Features • IP 68 execution as std (15 meters of water for 7 days). • Manual override (Hand-lever/wheel) with reduction gearing: • low effort on manual override: less than 350N for all the models • output torque still monitored in case electronics is powered on (in case back-up batteries are mounted) • “No cheater bars” design. • the clutch/declutch lever works on a low torque shaft: low effort to engage/disengage even with actuators under torque. • actuator self locking still available during manual operation. Optional AISI 316 Stainless Steel Hand wheel

Controls on board or not ? • It may be convenient to use electric actuators without on-board controls in case of : • high levels of vibration • high ambient temperatures • accessibility to the motor operated valve is limited after installation (however intelligent actuators can be supplied with separate control station). • Advantages of electric actuators with integrated controls: • Single responsibility (electric actuator manufacturer) of cabling and actuator control logic. • Full factory test of actuator, control wiring and control logic at actuator manufacturer care and responsibility.After factory test, controls are factory sealed: non-intrusive actuators generally do not need re-opening on site. • Reduced site wiring and reduced testing of wiring and control logic: no bad surprises on site. • Complete and easy factory acceptance test of complete actuated valve. • Direct processing of limit, torque and thermo-switch signals on the actuator. • Controls are dedicated to electric actuators, properly sized and designed according to actuator manufacturer 60 years experience.Standardized control logic: no need tore-invent for every application.
