1 The Keystone EPI 2 range of products provides an advanced, accurate and flexible series of quarter turn electric actuators from 63 to 2000 Nm Features The EPI 2 features a universal power supply to adapt to any voltage from 24 V DC/AC to 240 V DC/AC. Optionally 3-Phase power supply cards are available. All models have multiple adjustable stroking times to suit your typical valve application. The multi drilled base plate and range of shaft inserts ensures a flexible mechanical connection to any valve type. 6 models with adjustable torque cover the entire spectrum from 25 to 2000 Nm. The EPI 2 actuator features an intelligent control unit, which monitors the motor and internal temperature to prevent overheating. The spare slot provides multiple option possibilities i.e. modulating control, and network communication i.e. AS-interface, DeviceNet, Foundation Fieldbus and ProfibusDP. A mechanical position indicator is at the top of the unit. The optional local control panel provides comfort when operating the valve manually, and provides an additional open/close indication of valve position. In case of power fail the valve can be operated by handwheel. The handwheel is constantly engaged, but doesn t rotate during operation. The epicyclical gearing ensures a reliable and smooth operation. Technical specification Electric motor duty cycle (at 40 C): S3-100% for open/close operation. S4-50% for modulating operation.

2 Design features Mechanical connection to the valve EPI 2 actuators feature a multi drilled base plate and a range of drive inserts to allow direct mounting to almost all valve types according the EN ISO 5211 and Keystone standard. Electric motor The electric motor with innovative universal power supply module is used in all EPI 2 actuators. Uniquely designed to automatically accept any single phase input voltages (from 24 to 240 V DC or AC). EPI 2 can simply be connected to the local power and it will adapt to the available power rating. Alternatively 3 phase voltages from V AC, V AC and 575 V AC are also available. Electric motor thermostat A thermostat to protect the motor temperature in hot applications is included as standard in the control circuit of the electric actuator. Heater A heater is standard available within the unit and is powered from the motor power supply. It is automatically activated when the temperature drops below 10 C in order to prevent condensation. Actuator service The standard actuator is suitable for open/close and modulating applications. For open/close applications the motor rating is S3-100% duty and for modulating applications S4-50% (maximum of 1200 starts/hour at 40 C). Compact and light design EPI 2 actuators are very compact and balanced for easy installation to small valves minimizing pipe work stress or loads to the valve shaft. Actuator configuration Each actuator is equipped with 2 rotary switches on the logic board to configure each function and parameter like position, torque, open/close speed and output contacts. Additionally each option has its own additional switches for its specific configuration. Local manual override A constantly engaged manual override (not rotating during motor operation) is fitted to all EPI 2 actuators. Torque and sizing The EPI 2 range comprises of six models, for operating torques of up to Nm with a configurable operation time from 10 to 400 seconds. The nominal output torque value is constant along the entire stroke. Non-intrusive configuration With Bluetooth wireless technology enabled on your PDA or PC all configuration requirements can be undertaken without opening the unit. Direct access to the EPI 2 is then available for configuration and predictive/preventative maintenance information, including valve position, actuator speed, output torque, alarm and status. Position monitoring The EPI 2 provides a local mechanical position indication. For remote indication the position is detected by a non-contact Hall effect sensor. The open and close position are configured via the electronic control card. Electronic controls Internal drive to reverse the actuator direction of rotation via 24 V DC remote control signals with Internal or External 24 V DC power Tyco reserves the right to change the contents without notice page 2

3 Option modules OM1 Modulation and retransmission module Analog position input of 4-20 ma or 0-10 V DC (selectable). Analog position output of 4-20 ma or 0-10 V DC (selectable). Monitor alarm output contact to indicate loss of power, torque alarm, over temperature of motor or electronics and loss of analog signal. Motor running output contact. Four additional SPST output contacts set independently at one of 10 positions along the stroke. All contacts are configurable make of brake. OM3 Local interface Integral pushbutton panel with local/remote selector, open/close pushbuttons and 2 LED s (red/green) for local position indication. OM4 Bluetooth interface This module allows non-intrusive configuration and diagnostics of all actuators and their option modules. Bluetooth communication is possible by means of a PDA or PC with the A-Manager software installed. This software is password protected and offers different levels of security. With the A-Manager software the configuration can be stored and reloaded to the actuator. All active alarms are visible, and with the correct password level remote operation of the actuator is possible. OM8 AS-interface module The AS-interface module allows cyclic control and status communication to the control system according the IEC standard and supports the V2.1 specification. OM9 Profibus DPV1 module The Profibus DPV1 module allows cyclic communication (V0) and acyclic communication (V1) according to the IEC standard. This module provides control and remote configuration from the master station, and also alarm status information. This module can be used for both open/close as modulating applications. OM10 Foundation Fieldbus TM module The FF interface module is in the testing phase and has not been release yet. OM11 - DeviceNet TM module The DeviceNet module allows cyclic communication according the IEC standard. This module provides control and remote configuration from the master station, and also alarm status information. This module can be used for both open/close as modulating applications. OM13 3-wire interface This module changes the standard 5-wire control strategy into a 3-wire control strategy by combining the power and control commands. Only available for V AC applications.
