Product Brochure 2000 EFS2000: the hi-tech electric fail-safe actuator A simple electric actuator designed and engineered to operate safety valves with ICON2000 advanced and reliable solutions
Features More than half a century ago Biffi started its business in valve actuation. Its world-wide leadership has been built through continuous innovation and the ability to face the new challenges that a fast changing environment comes up with. It was in 1992 that Biffi started its intelligent actuator campaign. Since then Biffi Intelligent actuators have been welcomed by all major companies around the world, in many different applications: platforms, deep tropical forest, Siberian chill and harsh desert environment. With ICON2000, we made a further step forward towards ease of use and maintenance. Release 2004 of ICON2000 introduces a new philosophy in the construction of electric actuators electronic cards: all major optional functions are integrated in the base card, which allows easy plug-in of future upgrades. EFS2000 is the latest step in the acknowledgement of Biffi product quality and reliability. EFS2000 integrates in one single actuator all the advanced technological solutions of the ICON2000v4 with a strong and reliable spring-return mechanism for safe applications. The EFS2000 is an Electric Quarter Turn Spring Return Actuator which has the purpose to close or open a valve in emergency conditions, when an ESD alarm signal occurs or when motor power supply fails.

The EFS2000 actuator consists of six main parts: 1. a spring return mechanism, which moves the valve in the foreseen fail-safe condition when requested by an ESD signal or by a motor power failure. 2. a multiturn electric actuator which operates, through an epicyclic gear reduction (3) the valve during normal working conditions and in the mean time compress the spring when the operation is in opposite direction to the fail safe direction. 3. an epicyclic gear reduction, which increment the torque of the multi turn actuator and transform the stroke into a quarter turn value. 4. an electro-magnetic clutch which hold in position the female wheel of epicyclic gear (3) during the normal operation and release it in case of fail-safe function. 5. an hydraulic control group which is necessary to adjust the fail-safe speed and to manually operate the actuator by means of a hand-pump in case of power failure. 6. a local control and configuration panel which is utilised to configure the functional parameters and to operate locally (OPEN/CLOSE/OFF-EMERGENCY/RESET) the actuator when electric power is present. Working Principle The spring return system is kept in fail safe position by helical springs. During the normal operation the multi-turn turn electric actuator transmits the movement to the valve through the epicyclic gearing reduction and to the spring return mechanism through the rack. Spring return mechanism is based on rack-pinion mechanism; the rack is connected in one side to the spring and in the other side to the hydraulic cylinder; pinion of rack-pinion mechanism is connected to the valve stem. Input shaft of the epicyclic gearing reduction is connected the multi-turn actuator output shaft; output shaft of the epicyclic gearing reduction is connected to the pinion of rack-pinion mechanism. The female wheel of the epicyclic reduction is reversible: during normal operation it is kept on position by means of a electromagnetic clutch which hold the worm shaft connected to the epicyclic gearing. The coil of the electromagnetic clutch is normally fed by a direct current from separated external power source, or derived from motor power voltage, through a supply module. When the ESD condition occurs, the supply to the electromagnetic clutch is cut causing the disconnection of system which hold the worm shaft: in this conditions the epicyclic gearing become reversible causing the movement of the actuator on the fail condition by the effect of the spring. To avoid dangerous shock to the valve during the ESD action, an hydraulic damper is mounted on the spring system, whit an adjustable flow control orifice to be set to obtain the specified ESD times. Position of the valve is continuously monitored both in electric mode, both in fail-safe condition, by means of a position sensor directly connected the EFS output drive. After a Fail-Safe action, a local RESET is required, through the local control panel. Emergency Closing Operation In case of electric supply failure the electromagnetical lach opens and the actuator moves the valve in closing position by spring 4
Fail safe time regulation The closing time is adjustable by flow regulator 526 Local manual operation to open In case of loss of electric supply, switch valve 998 to manual mode and actuate hand pump 540 to open the actuator Local manual operation to close With valve 998 in manual position press the lever of hydraulic pushbutton 414, the actuator moves in closing by spring 1 Single acting spring return hydraulic actuator 30 Hydraulic accumulator (piston type/spring return) 352 Needle valve 356 Hydraulic filter 379 Check valve 395 Safety relief valve 414 2/2 N.C. hand-operated spring-return valve 526 Bidirectional flow regulator 527 Nozzle 528 Unidirectional flow regulator (adjustable setting) 540 Handpump 621 LP/HP pressure gauges 966 Terminals enclosure 998 2/2 N.C. hand-operated valve (auto/manual) 999 Electromagnetical latch 398 PST SOV (optional) Selector 998 is drawn in AUTO position Control Group Functions EFS2000 are equipped with an Hydraulic Control Group with two base functions: Adjustment of fail safe time Manual override function to operate the EFS when electrical power is not available. Adjustment of fail safe time is done trough the flow control valve (528). Manual override through the hand pump (540). Before to perform the local manual operation by hand-pump it is necessary to guarantee that the electromagnetic clutch is open: press the pushbutton OFF (Red mushroom) on the local control panel to be sure that clutch is really open. After the above operation, using a local two-positions (AUTO/MANUAL) hydraulic selector (998), select the local operation mode and successively through the hand pump manual operation can be carried out. At the end of manual operation, if the actuator is required to remain in the position opposite to the spring, it is necessary to leave the hydraulic selector in MANUAL position. To restore the electric mode function the hydraulic selector must be moved to AUTO position and, as soon the electrical power is available, the red mushroom pushbutton must be pressed to RESET the actuator. Select then LOCAL or REMOTE position, on the local control panel, according to the wanted type of operation.

...in cost reduction and user-friendliness The reduced number of mechanical parts ensures higher reliability and lower maintenance costs. The aluminium alloy highly resistant housing and covers, together with a lower number of joints, have increased EFS capacity to stand up to the most aggressive environments. A double-sealed enclosure assures protection from dust and humidity. The choice of internal components has increased the overall system efficiency (the motor is directly engaged to the gears) lowering the operational costs. Reduction of training costs is also one of the goals we have achieved through the user-friendliness of the system. No more codes to decipher: the EFS menu is clear and easy, and comes with all the following languages: Italian, English, Spanish, Portuguese, French,Turkish, Russian and Norwegian. Torque sensor The direct measure of the motor speed reports torque with high precision and a resolution of 1% of the nominal torque. Torque detection is based on motor torque vs. speed characteristics, voltage and temperature compensated. The torque vs. speed curve is memorised for each type of motors and in case of motor replacement simply a new configuration from the actuator local control panel is requested. Position sensor Low power consumption, long-life, absolute position sensor controlled by a dedicated microprocessor. Rotations in both senses are recognised and counted. If manually operated during power failure, the position is updated, stored and displayed locally. Electronic card: the latest technology The card is controlled by an high-performance microchip, with a slash memory. This allows high flexibility and the possibility to be re-programmed if necessary. The internal wiring is considerably reduced. The modular design of the electronic cards allows high flexibility for a great variety of combinations. All the electronic cards are treated with a tropicalisation protection in order to increase the performances even in the most severe enviromental conditions. 6

The base version is an intelligent actuator with hardwired (i.e. point-to-point) connection. High profile standards: all major features are included in the base version. Automatic phase correction The valve will be protected as the system automatically recognises and corrects phases preventing any unforeseen error in the rotation direction. Phase failure correction In case of loss of one phase, this features prevents the motor from overheating. The minimum time to set the alarm on is 100 ms, in order to prevent the system from being influenced by casual oscillations. In case of loss of one phase during motor running, the actuator will reach the end-of-travel position before setting the alarm condition and de-energising the actuator. Motor thermostat If during operation the temperature of the motor overrides the security limits, a thermostat will set the alarm condition and the command signal will be inhibited. Jammed valve protection If, after a command (close/open), the valve position does not change within a pre-set time, an alarm condition is set and the command signal will be inhibited. The pre-set time can be any time within an interval of 2 to 100 seconds. Anti-hammer protection This feature will protect both the motor and the valve. If a torque limit is reached it will prevent the valve from moving in the same direction which caused the torque limit. Instantaneous reversal protection When the actuator is operating in one direction and an immediate command for a reverse direction is set, unpredicted current surges arise with possible damages to the motor. To prevent such problems, a delay between the opposite commands can be programmed from 500 ms to 5 seconds. Warnings Warning signals become active when the operating conditions are close to a critical alarm level. Warning is displayed but operation is not interrupted. Remote controls Three different configurations are available: - 4 wires (OP, CL, Stop, C/latched) - 3 wires (OP, CL, C/push-to-run or latched with instant reverse) - 2 wires (NO contact to open or reverse) Control voltage - 24Vdc, internal supply - 20 to 125 Vdc, external supply - 20 to 120 Vac, external supply 14
15
Emergency Shutdown (ESD) When an ESD signal is received, the actuator performs the ESD programmed action, moving on the fail position under the action of the spring. The ESD action is performed by default when the ESD signal is sent. Other conditions for ESD can be configured through the local interface: - ESD in case of loss of main power; - ESD in case of Local Selector selected in OFF position - ESD by an emergency local pushbutton (mushroom type). Local RESET After an ESD action, normal operation can be restored after a Local RESET through the local pushbutton, or rather be automatically restored, depending on configuration. Analogic position retransmission Through 4-20mA with galvanic insulation Remote output contacts 7 voltage-free latching contacts and 1 change-over, voltage-free contact of relays are available for remote indication. They can all be configured as Normally Open or Normally Closed for one of the following conditions: - Fully open - Fully closed - Intermediate position - Position XX % - Position XX % - Actuator opening - Actuator closing - Motor running - Blinker - Local selected - Remote selected - Local stop active - PST active - Manual operation - Motor over temperature - Torque alarm - Torque alarm in opening - Torque alarm in closing - Jammed valve alarm - Jammed valve in opening - Jammed valve in closing - Mid-travel alarm - Warning - Low battery - EFS in manual mode - PST failed - EFS mid-travel alarm - MAINS (only for AS8) Interlock controls Two interlock inputs are available to inhibit actuator movement in open or close direction 16
Monitor relay When the actuator is not available for remote control, an alarm condition is set through a Monitor Relay with a change-over type, voltage free contact. The Monitor Relay is normally energized and will be de-energized under one of the following conditions: - loss of main power - speed sensor failure - loss of one phase - HW error - internal temperature alarm - mid-travel alarm - electrical contactors failure - configuration error - position sensor failure - EFS mid-travel alarm - EFS in manual mode The following other conditions can be individually configured to switch over the Monitor Relay: - motor over temperature - Manual operation selected - over torque - ESD action - jammed valve - Local STOP pushbutton pressed - LOCAL or OFF selected - Low battery Contactor failure As one of the vital parts of the actuators, contactors are continuously monitored. If a malfunction is detected an alarm is set and the command is inhibited. Maximum torque alarm During torque operation, if the current torque exceeds the relevant set value, the actuator command is inhibited and an alarm condition is set. Opto-coupled remote controls Actuator may be remotely controlled by 4, 3 or 2 wires, depending on the connection on the terminal board. Several options are available: latched, momentary, etc... Torque alarm by-pass During opening command, starting from open/closed position it is possible to set an interval from 0% to 20% of the total stroke where torque alarm is ignored. This will allow the actuator to win the Break-to-open torque. High/Low electronic temperature Through a semiconductor-based temperature sensor, the temperature in the electronic card is detected and an alarm condition is set on reaching the lowest/highest limits. 17
Local operator interface The local interface is designed for easy operation and to supply a complete and clear set of information. It is composed of - a padlockable three-position selector for LOCAL/OFF/REMOTE operation selection - two pushbuttons for local OPEN/CLOSE controls and menu navigation - one pushbutton for local stop - 2 customised displays, with backlight and heater: numeric 3 1 / 2 digit display for torque and position indication graphic display supporting various character sets 3 bi-coloured LED (green/red) to indicate fully open/closed/intermediate position 1 bicoloured LED (red/yellow) to indicate alarm/warning state. 1 blue LED to indicate Bluetooth connection active. Class 2 Bluetooth module available for wireless connection to PDA or PC. All buttons are recessed for protection from accidents or misuse. The local pushbuttons OPEN/CLOSE can be configured with 3 options: latched, latched + instant reverse, push-to-run. Through the local interface the field operator can enter a basic configuration menu which allows to set the following parameters: Base parameters - End of travel position in opening/closing - Opening/closing torque values - Position/torque display - Opening/closing by torque/position - Output contacts - PST function - Remote/Local control feature - ESD feature Extended parameters - Timer parameters - Position servo-amplifier parameters - Fieldbus interface parameters - Data logger - Maintenance date - Diagnostic info -.
