Technical specification | This description provides the basic specification, please refer to the Schedule of Equipment for actuator size, mounting flange, area classification, power supply and performance data. Remote control and indication functions are described under the Wiring Diagram. Additional options may also be found in Extras Included. Further technical details are provided in the IQ/IQT (3rd Generation) product range brochure PUB002-038 which is available at http://www.rotork.com/en/master-record/8923 • INGRESS PROTECTION: IP66/IP68 - 20 metres/10 days, double-sealed terminal compartment • TEMPERATURE: -30° C to 70° C (-22° F to 158° F) for Watertight, FM or CSA EP enclosures, -20° C to 70° C (-4° F to 158° F) for ATEX or IECEx enclosures • MOTOR: Three phase low inertia squirrel cage motor, class F insulation, incorporating thermostat protection. • SERVICE/DUTY RATING: Class A (On/Off)/Class B (Inching), nominal 60 starts at a rate ≤ 600 starts/hour. 15 minute rated at nominal 33% of rated torque • STARTER: Integral electrically and mechanically interlocked reversing contactors. • DRIVE: Incorporates lost motion ‘hammer-blow’, for releasing sticking valves • SYNCROPHASE: Auto Phase rotation correction and lost phase protection • LOCAL CONTROLS: Open/Close selector and padlockable Local/Stop/Remote selector (stop remains available for safety) • LOCAL INDICATION: Integral illuminated, digital valve position indicator showing 0.1% increments in position with closed and open limit symbols, torque, alarms and other status data. 3 LED's; red-open, yellow-intermediate, green-closed (can reverse), blinker and alarms configurable. • BATTERY SUPPORT: Battery is not required for position sensing but, supports LCD display, operation of indication relays, commissioning and data logging in absence of mains power • POSITION SENSOR: Absolute encoder with 8000 turn, 0.1% resolution with built in redundancy, provides continuous high resolution position measurement which is fully maintained during manual operation and without mains power or battery support • MOUNTING: Can be in any orientation, local indication and controls rotatable in 90° increments to suit • MANUAL OVERRIDE: Padlockable clutch lever, Handwheel clockwise to close, automatically disengages when motor starts and non-rotating during electric operation • LUBRICATION: Gearcase oil filled for life • TORQUE SWITCHES: Adjustable electronic torque switches 40% to 100% of rated with start of travel bypass option. • COMMISSIONING: Non- intrusive setup of; travel limits (auto setup option), relays, alarms and other functions via Infrared/Bluetooth Setting Tool (one supplied with each order). Can be password protected • DATA LOGGING/ASSET MANAGEMENT: Date/time stamped logging and display of operational events/trends, motor starts and valve torque profiles. Valve/actuator and gearbox data can be stored and service alarms set. Data download via Infrared/Bluetooth Setting Tool for upload to a PC and analysis via free InSight2 software • CABLE ENTRIES: 4 threaded entries Metric, NPT or PG, cable glands not included • TERMINALS: M5 power and M4 control terminals, screws and washers supplied. For ring tag conductors, power 16.0mm², controls 4.0mm² • PAINT: Polyester powder coating 100 micron nominal thickness. Colours: Housings/Covers - Grey (00-A-05), Handwheel/Hand Auto Lever/Base – Black CURRENT POSITION TRANSMITTER The Current Position Transmitter (CPT) provides a non-contact internally fed 4-20mA analogue signal proportional to valve position. Selectable for minimum signal corresponding to fully Close or fully Open position with automatic zero and span setting. The maximum external impedance that may be connected to the signal is 500 ohms at nominal supply voltage. Repeatability is within +/- 1% and linearity +/-1% of total valve travel. Wiring Diagram 101K2030 is described in IQ/IQT Control and Monitoring publication (PUB002-041) and includes: • POWER SUPPLY: Please refer to the Schedule of Equipment • CONTROL SUPPLY: 20 – 60VDC/40 – 120VAC or actuator derived 24VDC. • CONTROL INPUTS: 6 inputs for open, close, stop/maintain, ESD and interlock signals, 20 – 60VDC/40 – 120VAC • INDICATION CONTACTS: 4 volt-free (SPST) latching contacts (S1-S4), rated at 120VAC/30VDC, 5mA to 5A, each configurable NO or NC to signal one of the following; open/closed or intermediate positions, moving (continuous or pulsing), Handwheel operation, local selected, remote selected, open/close interlock active, ESD active motor tripped on torque in mid travel/going open/going closed, valve jammed, loss of power/phase or control supply, battery low, internal failure detected, thermostat tripped, programmable service alarms. • MONITOR AND AVAILABILITY RELAY: Independent relay with volt-free changeover contact, rated at 120VAC/30VDC, 5mA to 5A. De-energises in case of; loss of power/phase or control supply, local control or local stop selected (can be excluded), motor thermostat tripped or detected internal failure • ANALOGUE FEEDBACK: 4-20mA output proportional to position (CPT), internally powered. • NETWORK CARD: Pakscan. Single Channel • SIL STAYPUT FUNCTION: 'Motor Enable' contact gives permissive control function to allow actuator to be used in safety related systems up to and including SIL 2 (1oo1) and SIL 3 (1oo2) |
