2 Save this InstructionManual for future reference. If you do not understand any of the instructions, contactyour Rosemount representative for clarification. Follow all warnings, cautions, and instructions markedon and supplied with the product. Inform and educate your personnel in the proper instal-lation, operation, and maintenance of the product. Install your equipment as specified in the InstallationInstructions of the appropriate Instruction Manual andper applicable local and national codes. Connect allproducts to the proper electrical and pressure sources. To ensure proper performance, use qualified personnelto install, operate, update, program, and maintain theproduct. When replacement parts are required, ensure that qual-ified people use replacement parts specified byRosemount. Unauthorized parts and procedures canaffect the product s performance and place the safeoperation of your process at risk.

3 Look alike substitu-tions may result in fire, electrical hazards, or improperoperation. Ensure that all equipment doors are closed and protec-tive covers are in place, except when maintenance isbeing performed by qualified persons, to prevent electri-cal shock and personal SHOCK HAZARDM aking cable connections to and servicing thisinstrument require access to shock hazard levelvoltages which can cause death or serious injury,therefore, disconnect all hazardous voltagebefore accessing the contacts made to separate power sourcesmust be disconnected before installation must be in accordancewith the National Electrical Code (ANSI/NFPA-70) and/or any other applicable national or cable conduit entries must be securelysealed by non-flammable closures to provideenclosure integrity in compliance with personalsafety and environmental protection require-ments.

4 Use NEMA 4X or IP65 conduit plugs sup-plied with the instrument to maintain the ingressprotection rating (IP65).For safety and proper performance this instru-ment must be connected to a properly groundedthree-wire power relay use and configuration is theresponsibility of the user. No external connec-tion to the instrument of more than 60 VDC or43V peak allowed with the exception of powerand relay terminals. Any violation will impair thesafety protection not operate this instrument without frontcover secured.

Ions in water conduct currentwhen an electrical potential is applied across elec-trodes immersed in the solution. A controller systemconsists of a microprocessor-based controller, a con-ductivity probe, and mounting controller can use an electrodeless toroidal probeor a contacting probe with metal electrodes.

8 Electrode-less (also called inductive) conductivity measurementis especially useful for solutions containing abrasivesolids, highly conductive, or highly corrosive contacting probe is used where conductivity isbelow 200 micromhos, such as water rinses in metalfinishing or ultrapure boiler water applications. It usesan electrode design for greater sensitivity becausethese water solutions tend to be adjustments to the current outputs, alarm relays,and calibration of the pH and temperature inputs canbe made using the controller's membrane DESCRIPTION OF CONTROLSF igure 1-1 shows a diagram of the main displayscreen. Similar diagrams are used throughout thismanual. The primary variable is continuously dis-played in large numerals. The process temperatureand primary current output value are always displayedon the second line of the main display screen.

9 Thethird line can be configured to read several differentitems, as desired. In this case, it is displaying set-points for alarms 1 and F1-F4 keys are multifunction. The active operationfor that key is displayed as a label just above eachfunction key as needed. For example, F1 is usuallylabeled Exit and F4 may be labeled Edit, Save, orEnter. Pressing Enter 4will access sub-menus, whilepressing Edit allows changing values and Save storesthe values in memory. Esc 3can be used to abortunwanted changes. Exit 1returns to the previousscreen. Other labels may appear for more up tand down bkeys are used to:1. Move the cursor (shown in reverse video) up anddown on the menu Scroll through the list of options available for thefield shown in reverse video. When the last itemof a menu has been reached, the cursor willrest on the third line of the display.

10 If the cursoris on the second line, there are more items tosee with the down arrow Scroll through values when a highlighted numericalvalue is to be set or right and left keys are used to move the cursor tothe next digit of a LEDs (labeled 1, 2, and 3) indicate when alarmrelays 1, 2, and 3 are energized. The fourth relayindicates a fault condition. When a fault occurs, thered LED (labeled FAIL) lights up, a descriptive errormessage is displayed, and the action of the outputsand relays will be as described in Section andSection under fault value ( 22 mA).The red LED also indicates when the interval timer rou-tine is activated and when the time limit has beenreached on a feed limit timer.
