Semiconductor,Cap Conductor,Shield Isolation polypropylene dmin 5 mm. 6 ON OFF outputs are thyristor type offering innumerous advantages for the equipment such as no. sparks presence faster commutation noise practically inexistent no presence of RF interference and many. The outputs can commute any charge since they are powered by alternate tension VAC. 5 Equipment Installation cont, 5 2 Dissolved Oxygen Industrial probe Characteristics DOE 441. Dissolved Oxygen Immersion Probes for industrial application consists typically in an adequate installation. hardware whose function is to hold and protect the Dissolved Oxygen industrial cell model DOE 441 R and ti s. respective connections, In order to choose the adequate material to it s body construction will depend on work s chemical aggressiveness.
and temperature of the process Find below some materials available. a PP Polypropylene Model DOE 441 Standard, b Stainless Steel 316 Model DOE 441 S Special Order and others upon request. All connections offer guaranteed sealing by Nitrilic Rubber O Rings FKM or others The electrical connection is. done thru a terminal barr in an IP 68 case protection with cables going thru a NPT hole or cable pres and the. interconnection of the Probe s terminal barr to the cell being done by PA type connector It is recommended that the. connection cable from the probe to the equipment offers the shortest length possible in order to avoid RF. interference and noise problems, The installation of the Probe can be done by a pole or flange and the insertion length is defined based on the need of. measure to be taken being supplied with standard of h 1500 mm.

5 3 Automatic Cleaning System hose installation, Probes DOE 441 are supplied with Automatic Cleaning System whose function is to remove any clogging at the. membrane of the Dissolved Oxygen s Cell Typically the cleaning is done by pressurized air jet 3 bar maximum. The cleaning is executed a solenoid valve activation controlled by the equipment The time and duration of the. cleaning can be programmed by accessing the Set Up operation of the equipment s program. At slots 12 13 there is a thyristor contact S3 that commands the Solenoid for the cleaning system.

Important Information, 1 Never forget that if the instrument is turned off it is necessary to wait for the cell polarization aprox 12 min. 2 While at READ mode is possible to obtain other information such as. By pressing SEL key user can obtain the Temperature value or the Set Points programmed during SET UP. By pressing ENT key it moves the equipment to STAND BY mode While in STAND BY the outputs will be turned. off that means the current output goes to 4 mA and the contacts to NO The outputs must be programmed by the. 3 ESC key is only recognized when pressed and hold for about 5seconds This time is necessary in order to certify. that the user desires to exit the selected option, 4 During certain program steps it is allowed to adjust such values as Span salinity barometric pressure set points. hystereses and others The adjust is done by indication of arrows decrease and increase Press SEL key in. order to choose the correct option increase or decrease then confirm by pressing ENT key. Press SEL key again until user reaches the desired value then press ENT key to confirm. 5 When power failure occurs when the equipment turns back on the initial pre programmed conditions will remain as. prior to the power failure Wait for the Cell Polarization If the equipment is under READ mode it will return to. Reading and no further action will be necessary, While at Stand By if a power failure occurs the instrument will not return to reading mode after the polarization is.
completed it will go to the main menu select Function. 6 Syntonizing P Di Contol, The Period Value Di must be established in relation to the retention time of the process. Example Retention Time is equal 30 minutes establish a period of 1 minute. The Proportional Band BP must be equally established in relation to the reagent concentration and of the process. homogenizing power Start with 50 of PB and increase or decrease it in relation to its variable response. 7 Equipment Operation cont,Set Up Procedures, The Equipment offers a non volatil memory E2PROM in order to store operation s functions Resolution. Reading Mode Calibration etc Even when turned off from power all functions chosen during set up will. remain stored Before you start any work with the equipment it is recommended to verify the SET UP. conditions to certify that you have chosen the correct options fro your work and to avoid operation errors. Press and hold ESCAPE key until reached the Select Function Menu When at the SELECT FUNCTION. menu press SELECT key in order to select the function desired flashing option then press ENTER In. order to access the SET UP menu press SELECT key until SET UP flashes then press ENTER key to. confirm the option A Password will be requested press in sequence SELECT ENTER ESCAPE. and follow step by step the options shown at the display In case the user desires to switch the flashing. option press SELECT key and change as needed following the display commands then ENTER key. to confirm the option chosen, When a mistake is made and the user needs to go back to change it press ESCAPE The display will. move back one screen at a time for every option, At the flow chart the flashing option will be displayed in Blue Color. Check Operation, The option Sensor CHECK is very useful as it allows the user to verify the cell condition This option is self.
