Rotork has undertaken this process incrementallyand cautiously over the years. Originally the 1400 series wiring on our A range actuator was entirelyhardwired. In the early 1980’s we introduced the 1600 series A range that incorporated some solid statecontrolsand enhanced features such as automatic phase correction and enhance versatility of control. Many ofthese features were then complemented with the introduction of the IQ series in the early 1990’s. The mainadvance was the introduction of non-intrusive control setting. This enabled the settings ofthe actuator to beconfirmed or adjusted without a removal of electrical covers. The benefit being that no dirt or moisture couldcontaminate the internals ofthe actuator degrading its inherent reliability.  \nA further refinement of the IQ, designated IQ Mk. 2 was introduced in 2000. This actuator includes as standarda data logger so operational history can be downloaded to monitor performance and facilitate asset managementfeatures such as preventive or predictive maintenance.  \nWith these changes in our products have come some changes in the methods of installation and set up. Therequirements for Black Liquor recovery boilers are quite specific as defined in BLRBAC good practice. Wehave revisited these requirements and combined this with our experience to come up with the attachedrecommendations for wiring hook up and settings on our actuators.  \nWe hope that this document will act as a definitive reference manual forthe application of Rotork actuators onBlack Liquor recovery boiler valves.  \nGlossary  \nESP – Emergency shutdown procedure – As referenced in BLRBAC recommended good practice.  \nESD – Emergency shutdown – As referenced in Rotork literature.  \nDoc1572 Rev. 6 Page 3 of 26 11/18/05  \n## Section 2\n\nClarification of Application of the IQ Mk. 1 and Mk. 2  \nThere have been several questions regarding the Rotork ESD connections used forthe ESP function andthe  \nbattery functionsofthe Rotork IQ units. Below are some answers to most frequently asked questions.  \nBattery  \n### 1. Why does Rotork use a battery in its IQ actuators?\n\nAn LCD display is used to give position and other information locally at the actuator. There needsto be some form of back up power to provide this display should the main AC power be lost.  \nAdditionally, the remote indication in the control room needs to be updated should the actuator beoperated manually during loss of main power. The battery provides back up power forthe LCD andthe remote","cbCainHUPWRdXrbs","https://ap.wps.com/l/cbCainHUPWRdXrbs","pdf",1876352,26,"English","# Rotork\n## 1. Rotork Supply History\n## 2.
