Te factory default setting is 2.0% / C. Linear 20 C compensation adjusts te reading by a coefficient or factor expressed as %/ C (deviation from 20 C). Use only if te solution as a well-caracterized linear temperature coefficient. Te factory default setting is 2.0% / C. Glycol.5 compensation matces te temperature caracteristics of 50% etylene glycol in water. Compensated measurements using tis solution may go above 18 Mom-cm. Glycol1 compensation matces te temperature caracteristics of 100% etylene glycol. Compensated measurements may go well above 18 Mom-cm. Cation compensation is used in power industry applications measuring te sample after a cation excanger.

Te calibration is done using te last reading. If te criteria is not met witin 300 seconds ten te calibration times out and te message Calibration Not Done is displayed. Adjust te parameter IP ph. IP is te isotermal point value (Default = 7.000 for most applications). For specific compensation requirements or non standard inner buffer value, tis value can be canged. Adjust te value of te parameter STC ph/ C. STC is te solution temperature coefficient in units of ph / C referenced to te defined temperature. (Default = 0.000 ph/ C for most applications). For pure waters, a setting of 0.016 ph / C sould be used. For low conductivity power plant samples near 9 ph, a setting of 0.033 ph / C sould be used. If te value for STC is 0.000 ph/ C an additional input field for te reference temperature will be displayed. Te value for ph Ref Temperature indicates to wic temperature te solution temperature compensation is referenced. Te displayed value and te output signal is referenced to tis temperature. Most common reference temperature is 25 C.

It can be cosen between te last value (i.e. te value before te transmitter switced to te old mode) or an fixed value. Press te input field in te line for te setting of te Hold Mode and select te value. If a fixed value is cosen, te transmitter sows an additional input field. Additional settings can be done by navigating to te next page of te menu. Te Aout Type can be Normal, Bi-Linear, Auto-Range or Logaritmic. Te range can be 4 20 ma or 0 20 ma. Normal provides linear scaling between te minimum and maximum scaling limits and is te default setting. Bi-Linear will also prompt for a scaling value for te mid-point of te signal and allows two different linear segments between te minimum and maximum scaling limits. Press te button for te Min Value, tat corresponds wit start point of te analog output range. Press te button for te Max Value, tat corresponds wit end point of te analog output signal. Depending on te cosen Aout type additional values can be entered. Bi-Linear will also prompt for a scaling value for te Mid Value of te signal and allows two different linear segments between te defined Min and Max Values. Auto-Range scaling provides two ranges of output. It is designed to work wit a PLC to provide a wide measurement range at te ig end of te scale, and a narrower range wit ig resolution at te low end. Two separate settings are used, one for te maximum limit of te ig range and one for te maximum limit of te low range, for te single 0/4-20 ma signal. Max1 is te maximum limit of te low range on auto-range. Te maximum value for te ig range on auto-range is set wit te Max Value. Bot ranges ave te same minimum value tat is set troug Min Value. If te input value is iger ten value of Max1, te transmitter switces automatically to te second range. To indicate te currently valid range a relay can be assigned.

Te Type of te setpoint can be Hig, Low, Between, Outside or Off. An Outside setpoint will cause an alarm condition wenever te measurement goes above its ig limit or below its low limit. A Between setpoint will cause an alarm condition to occur wenever te measurement is between its ig and low limits. NOTE: If te type of set point is not Off additional settings can be done. See te following description. According to te selected type of setpoint, value(s) regarding te limit(s) can be entered. Additional settings can be done by navigating to te next page of te menu. Once configured a relay could be activated if a sensor Out of Range condition is detected on te assigned input cannel. To select te desired relay tat will be activated if te defined conditions are reaced press te input field in te line for te setting of SP Relay. If te cosen relay is used for anoter task, te transmitter sows te message on te screen tat tere is a Relay Conflict. Te operation mode of te relay can be defined. Relay contacts are in normal mode until te associated setpoint is exceeded, ten te relay is activated and te contact states cange. Select Inverted to reverse te normal operating state of te relay (i.e. normally open contacts are in a closed state, and normally closed contacts are in an open state, until te setpoint is exceeded). Enter te Delay time in seconds. A time delay requires te setpoint to be exceeded continuously for te specified lengt of time before activating te relay. If te condition disappears before te delay period is over, te relay will not be activated. Enter te Hysteresis as a percentage-value. A ysteresis value requires te measurement to return witin te setpoint value by a specified percentage before te relay is deactivated. For a ig setpoint, te measurement must decrease more tan te indicated percentage below te setpoint value before te relay is deactivated. Wit a low setpoint, te measurement must rise at least tis percentage above te setpoint value before te relay is deactivated. For example, wit a ig setpoint of 100, wen tis value is exceeded, te measurement must fall below 90 before te relay is deactivated. Enter te relay Hold Mode of Off, Last Value or On.

Transmitter M800 77 8.11 PID Controller PATH: H \ CONFIG \ PID Controller PID control is proportional, integral and derivative control action tat can provide smoot regulation of a process. Before configuring te transmitter, te following process caracteristics must be identified. Identify te control direction of te process Conductivity: Dilution direct acting were increasing measurement produces increasing control output suc as controlling te feed of low conductivity diluting water to rinse tanks, cooling towers or boilers Concentrating reverse acting were increasing measurement produces decreasing control output, suc as controlling cemical feed to attain a desired concentration Dissolved Oxygen: Deaeration direct acting were increasing DO concentration produces increasing control output suc as controlling te feed of a reducing agent to remove oxygen from boiler feedwater Aeration reverse acting were increasing DO concentration produces decreasing control output, suc as controlling an aerator blower speed to maintain a desired DO concentration in fermentation or wastewater treatment ph / ORP: Acid feed only direct acting were increasing ph produces increasing control output, also for ORP reducing reagent feed Base feed only reverse acting were increasing ph produces decreasing control output, also for ORP oxidizing reagent feed Bot acid and base feed direct and reverse acting Identify te control output type based on te control device to be used: Pulse frequency used wit pulse input metering pump Pulse lengt used wit solenoid valve Analog used wit current input device suc as electric drive unit, analog input metering pump or current-to-pneumatic (I / P) converter for pneumatic control valve Default control settings provide linear control, wic is appropriate for conductivity, dissolved oxygen. Terefore, wen configuring PID for tese parameters (or simple ph control) ignore settings of deadband and corner points in te tuning parameter section below. Te non-linear control settings are used for more difficult ph / ORP control situations. If desired, identify te non-linearity of te ph / ORP process. Improved control can be obtained if te non-linearity is accommodated wit an opposing non-linearity in te controller. A titration curve (grap of ph or ORP vs. reagent volume) made on a process sample provides te best information. Tere is often a very ig process gain or sensitivity near te setpoint and decreasing gain furter away from te setpoint. To counteract tis, te instrument allows for adjustable non-linear control wit settings of a deadband around te setpoint, corner points furter out and proportional limits at te ends of control as sown in te figure below.
