SAFETY INSTRUTION : This cntrller is meant fr temperature cntrl applicatins. It is imprtant t read the manual prir t installing r cmmissining f cntrller. All safety related instructin appearing in this manual must be fllwed t ensure safety f the perating persnnel as well as the instrument. GENERAL The cntrller must be cnfigured crrectly fr intended peratin. Incrrect cnfiguratin culd result in damage t the equipment r the prcess under cntrl r it may lead persnnel injury. The cntrller is generally part f cntrl panel and in such a case the terminals shuld nt remain accessible t the user after installatin. MEHANIAL The ntrller in its installed state must nt cme in clse prximity t any crrsive/cmbustible gases, caustic vaprs, ils, steam r any ther prcess by-prducts. The ntrller in its installed state shuld nt be expsed t carbn dust, salt air, direct sunlight r radiant heat. Ambient temperature and relative humidity surrunding the cntrller must nt exceed the maximum specified limit fr prper peratin f the cntrller. The cntrller in its installed state must be prtected against excessive electrstatic r electrmagnetic interferences. Ventilatin hles prvided n the chassis f the instrument are meant fr thermal dissipatin hence shuld nt be bstructed in the panel. ELETRIAL The cntrller must be wired as per wiring diagram & it must cmply with lcal electrical regulatin. are must be taken nt t cnnect A supplies t lw vltage sensr input. ircuit breaker r mains s/w with fuse (V/A) must be installed between pwer supply and supply terminals t prtect the cntrller frm any pssible damage due t high vltage surges f extended duratin. ircuit breaker and apprpriate fuses must be used fr driving high vltage lads t prtect the cntrller frm any pssible damage due t shrt circuit n lads. T minimize pickup f electrical nise, the wiring fr lw vltage D and sensr input must be ruted away frm high current pwer cables. Where it is impractical t d this, use shielded grund at bth ends. The cntrller shuld nt be wired t a -Phase supply with unearthed star cnnectin. Under fault cnditin such supply culd rise abve VA which will damage the cntrller. The Electrical nise generated by switching inductive lads might create mmentary Fluctuatin in display, alarm latch up, data lss r permanent damage t the instrument. T reduce this use snubber circuit acrss the lad. It is essential t install a ver Temp. Prtectin device t avid any failure f heating system. Apart frm spiling the prduct, this culd damage the prcess being cntrlled. Dcument Name : OIM AI-X (Ver.) Page f

In this mde is always related with. User can set value with deviatin f ± w.r.t. Abs OUTPUT LOGI User can select Heat lgic fr cntrl Output in which will remain ON till < ( increases when utput is ON). User can select l lgic fr cntrl Output in which will remain ON till > ( decreases when utput is ON). Heat TABLE : Belw listed parameters will appear nly if OUTPUT is selected as mde. In mde, ntrller cntinuusly cmpares with either (fr Deviatin r Band alarm) r an independent (fr prcess high and prcess lw Alarm). Alarm will ccur when falls utside the set Alarm limits. Als, will energize r de-energize under Alarm cnditin as per the Alarm lgic(al.lg) selected. HYS in ntrl list decides when t switch OFF the Alarm. Instrument supprts fur types f Alarm as described belw : - DESRIPTION Lw Alarm : activates when <. DEFAULT OUTPUT- ON OUTPUT- OFF OUTPUT- OFF OUTPUT- ON High Alarm : activates when >. TYPE OUTPUT- OFF OUTPUT- ON OUTPUT- ON OUTPUT- OFF Deviatin Alarm : activates when exceeds ± set deviatin value. OUTPUT OFF OUTPUT ON OUTPUT ON OUTPUT OFF Band Alarm : activates when falls utside the band w.r.t. in either directin. OUTPUT ON OUTPUT OFF OUTPUT ON OUTPUT OFF OUTPUT ON OUTPUT OFF DEVIATION LOGI INHIBIT AK. If this parameter is set as Direct, Relay/SSR energizes under Alarm cnditin & remains De-energized therwise. Direct setting is generally used fr Audi/Visual Alarm Output. If this parameter is set as Reverse, Relay/SSR de-energizes under Alarm cnditin & remains energized therwise. Reverse setting is generally used fr tripping the prcess under Alarm cnditins. If this parameter is set t YES & Alarm cnditin persists, it will Disable Alarm O/P at pwer ON. If this parameter is set t NO & Alarm cnditin persists, it will Enable Alarm O/P at pwer up. Once the Alarm is activated, User has fllwing three ptins t de-activate it. When falls within the prgrammed limits The Alarm will be de-activated autmatically. Once the alarm is activated, it remains activated until acknwledged manually by UP key. Once the alarm is activated, it can be de-activated either by pressing UP key r when falls within the alarm limits. DIRET NO AUTO Dcument Name : OIM AI-X (Ver.) Page f
