Incorrect configuration could result in damage to the equipment or the process under control. v The controller is generally part of control panel and in such a case the terminals should not remain accessible to the user after installation. MECHANICAL v The Controller in its installed state must not come in close proximity to any corrosive/combustible gases, caustic vapors, oils, steam or any other process byproducts. v The Controller in its installed state should not be exposed to carbon dust, salt air, direct sunlight or radiant heat v Ambient temperature and relative humidity surrounding the controller must not exceed the maximum specified limit for proper operation of the controller. ELECTRICAL v The controller must be wired as per wiring diagram & it must comply with local electrical regulation. v Circuit breaker or mains s/w with fuse (275V/1A) must be installed between power supply and supply terminals to protect the controller from any possible damage due to high voltage surges of extended duration. v Circuit breaker and appropriate fuses must be used for driving high voltage loads to protect the controller from any possible damage due to short circuit on loads. v To minimize pickup of electrical noise, the wiring for low voltage DC and sensor input must be routed away from high current power cables. Where it is impractical to do so, use shielded ground at both ends.

By this parameter user can select four format of resolution only for analog input, i.e. "0.000, 0.00, 0.0, 0 0". For range limit as per resolution selected Ref. Table No.2 (Page No. 4). ANALOG INPUT LOW VALUE ANALOG INPUT HIGH VALUE By this parameter user can define Low scale for input signal. Which can be in between `-1999 to Ai.Hi'. For range limit as per resolution selected Ref. Table No.2 (Page No. 4). By this parameter user can define HIGH scale for input signal. Which can be in between `Ai.Lo to 9999'. For range limit as per resolution selected Ref. Table No.2 (Page No. 4). 0 1200 By this parameter user can select the logic of the Analog Input. User Calibration Lisit:- Analog Input Logic PROCESS VALUE OFFSET INPUT FILTER USER LOCK CODE `DIR' :- If selected then the value will vary from Ai.Lo to Ai.Hi. `REV' :- If selected then the value will vary from Ai.Hi to Ai.Lo. Function of this parameter is to add/subtract a constant value to the measured PV to obtain Final PV. For range limit as per resolution selected Ref. Table No.2 (Page No. 4). Controller is equipped with an adaptive digital filter which is used to filter out any extraneous pulses on the PV. Filtered PV Value is used for all PV dependent functions. If PV signal is fluctuating due to noise, increase the filter time constant value. Default USER LOCK CODE is 15 to access Control & Configuration List. User has a choice to set its own USER LOCK CODE between 1 to 9999, this is to prevent unauthorized access of Control & Configuration List.
