T80 Moun0ng Dimensions

Model T80 Universal Transmi)er Main Display screens; the Data Screen, the Millivolt Screen and the Graphical Display screen. The Data Screen displays the measurement type, the measured value with units, the % milliamp output of the 4-20 mA channel and the temperature. The mV Screen displays the measurement type, the raw millivolt signal from the sensor, the % milliamp output of the 4-20 mA channel and the temperature. The Graphical Screens display the measurement type, the measured value with units and a graphical representa0on of the % milliamp output. Three graphical styles are available; a Trend line, a Bar graph or a Gauge. The status of alarm relays, energized/de-energized is displayed on transmi1ers with relays.

MENUS

Menu naviga0on is accomplished using membrane switch bu1ons. So! keys display the func0on associated with each bu1on. Pressing any of the bu1ons twice within 2 seconds ac0vates the Model T80 so! key menus. The primary selec0ons are the Calibra0on menu, Configura0on menu, Info Screens and Simulate menu.

CALIBRATION

Model S80 sensors come precalibrated from the factory. Field calibra0ons are easily performed with the Model T80. The Calibra0on menu includes the Auto Cal func0on, a two point calibra0on, the Standardize func0on, a single point calibra0on or the Manual Calibra0on, where previously determined Offset and Slope values are entered manually into the Model T80 transmi1er.

CONFIGURATION

The Configura0on menus allow the Model T80 transmi1er’s Display and Output func0ons and the Model S80 sensor’s characteris0cs to be configured or adjusted. Display screens include the Hold func0on, Graphical Display Style, Back Light and Contrast adjustments, Labels/Tags for naming the transmi1er, Password Protec0on and a Factory Default reset. Output screens include se2ng the addresses for MODBUS or HART® outputs, se2ng the 4-20 mA Range and fault se2ngs and configuring the Alarm Relays.

INFO

The Info screens provide Transmi1er and Sensor Informa0on. The transmi1er screens display the Name, Power, Serial#, Firmware version and the output configura0on. The sensor screens display the Name, Part #, Serial # and stored Calibra0on data.

SIMULATE

The Simulate Menu allows the input and output signals to be simulated. The outputs are easily tested by entering a 4-20 mA output value or energizing and de-energizing a relay. The Ramp func0on cycles the signal across the configured 4-20 mA range, i.e. the transmi1er generates a signal from 0 pH to 14 pH and back to 0 pH ac0va0ng relays and genera0ng a 4-20 mA output. The cycle 0me and the dura0on are adjustable allowing sufficient 0me for an individual to walk to the control room to verify the output.

POWER SUPPLY and OUTPUTS The Model T80 transmi1er is available as a loop powered (single channel only), a 24 VDC or a 100/240 VAC powered transmi1er. The loop powered version is available with an op0onal HART® output. The line powered instruments have one 4-20 mA output per channel and MODBUS RTU. Available op0ons include HART®communica0on and an Alarm Relay package. The (3) relays can be configured as Alarm (set point) relays, 0mer ac0vated relays or Fault relays.

T80 Home Screens

Descrip(on The ECD Model T80 Universal Transmi)er is a single or dual channel transmi1er designed for the con0nuous measurement of pH, ORP, pION, Dissolved Oxygen, Turbidity, Conduc0vity or Resis0vity in a general purpose industrial environment. The Model T80 transmi1er digitally communicates with any ECD Model S80 Intelligent Sensor, automa0cally configuring the transmi1er’s menus and display screens to the measured parameter. The same transmi1er can be used for any of the measurements, i.e. plug an S80 Conduc0vity Sensor into a Model T80 pH transmi1er and it will automa0cally reconfigure into a conduc0vity transmi1er. There is no longer any need to inventory mul0ple instrument types, the one Model T80 transmi1er will automa0cally configure to any of the listed measurements.

SENSORS

The Model S80 Intelligent Sensors facilitate two way communica0on with the Model T80 transmi1ers. The type of sensor, iden0ty and serial number are stored in the sensor’s memory along with calibra0on registers. The Model S80 sensors are calibrated at the factory so they are ready to use when connected to a Model T80 transmi1er. The Model S80 sensors are waterproof and submersible with all internal components epoxy encapsulated inside the ¾” O.D. housing. The Model S80 sensors use the same field proven, easily replaceable electrodes as the Model S10 and S17 sensors saving 0me and money. A digital converter op0on is available for the Model T80 transmi1er to allow the use of non-digital sensors. The digital converter is only available on line powered instruments.

DISPLAY

The Model T80 Transmi1er features a large easily viewed LCD display. Loop powered instruments have Black le1ering on a Grey background, while 100- 240 VAC and 24 VDC powered instruments have Blue le1ering on a White background when the LED backlight is on. The Model T80 display is easily switched between the single and dual channel display modes. It has three

3.0 OPERATION

The ECD Model T80 transmitter is an intelligent, single or dual channel multi-parameter transmitter designed for the online continuous measurement of pH, ORP, pION, conductivity, resistivity or Dissolved Oxygen in a general purpose industrial environment.

The Model T80 transmitter digitally communicates with any ECD S80 digital sensor. The measurement identity is contained in the sensor’s memory. When an S80 sensor is connected to the transmitter it automatically configures the transmitter’s menus and display screens to the measured parameter.

3.1 KEYS

The functions associated with each key are displayed on the screen, above the key for the Selection Adjustment

Keys and to the left of the key for the HOME and BACK keys. Press any Selection Adjustment key twice within one second to enter the HOME Menu Screen.

3.1.1 HOME/EXIT KEY

The HOME key performs two functions, it selects which Home Screen is displayed and it returns the active screen to the HOME Menu Screen from anywhere inside the menu structure.

Three Display screens are available:

1. DATA SCREEN: Displays the measurement type, numerical value, engineering Units, % Output of the 4-20 mA channel and temperature.

2. mV SCREEN: Displays the measurement type, the sensor’s raw millivolt Value, % Output of the 4-20 mA channel and temperature.

3. GRAF SCREEN: Displays a Graphical representation of the 4-20 mA channel

% Output, the measurement type, the engineering units, and temperature.

Only one of the three graphical display styles is available through the HOME key, either the Bar, Gauge or Line display. Choose which style will be displayed in the Graph Menu. (pathway to Graph Menu: CONFIG → XMTR

→ LCD → Graph menu)

Each of the above screens also displays the condition of the optional Alarm Relays, black if energized and white if de-energized.

The HOME key changes to the EXIT key in the HOME Menu Screen, pressing EXIT prompts the user to “Save Changes” YES/NO when exiting the HOME Menu. YES applies any changes made in the menus, NO exits the HOME Menu without applying any changes made in the menus.

3.1.2 BACK/HOLD KEY

The BACK key changes the screen to the previously displayed screen when inside a menu, it moves BACK one screen. On a dual channel transmitter it toggles between the PV1, PV2 and Dual

Channel Screens. The HOLD key toggles the output HOLD function ON/OFF in the MENU HOME screen.

Page 21 Model T80

3.1.3 SELECTION ADJUSTMENT KEYS

The (4) Selection/Adjustment keys allow navigation and numerical adjustments to be made in the MENUs. To enter the HOME Menu screen press any of the Selection/Adjustment keys twice within one second. The various Menu choices and adjustment tools are displayed above the buttons once inside the MENU.

3.1.4 ALPHA NUMERIC ENTRY

The LABEL and PASSWORD (Caps and Numbers only) Menus allow alphanumeric entry. Entry is accomplished by scrolling through the alphanumeric list with the ▲ (forward) and ▼ (backwards) arrows to the character of choice and then moving to the NEXT digit. Pressing and holding the ▲ or ▼ keys will initiate two speed auto scrolling. The character set is sequentially listed below. The first character in the set is an empty space.

! ” # $ % & ‘ ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? @ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ ¥ ] ^ _

‘ a b c d e f g h I j k l m n o p q r s t u v w x y z { | } → ←

3.2 MENU STRUCTURE

Double tap any Selection/Adjustment key to enter the HOME Menu Screen. Five menu choices will appear, CAL, CONFIG, INFO, SIM and HOLD. Each of the Menus is detailed below.

3.2.1 HOLD (OUTPUT HOLD)

Pressing the HOLD Key activates the HOLD function, HOLD is ON, displayed.

Freezes the 4-20 mA output at the last value prior to activation

Freezes optional Alarm Relays in the current state

While in the HOLD mode the % Output display toggles between the last value and HOLD

Pressing HOLD again turns the hold function off, Hold is OFF, displayed. The HOLD function remains ON until it is turned OFF. (See Time Out in CONFIG>XMTR>OUTPUT>HOLD)

3.2.2 CAL (CALIBRATION MENU)

Four options are available, AUTO, STAND, MANUAL and TEMP. On dual channel instruments choose Sensor 1 or

Sensor 2 when prompted.

The first screen asks, “Is this a New Sensor, YES / NO”. If YES the calibration history from the previous sensor is cleared from memory and a new register is started, if NO then the calibration is written to the memory stack, (3) sets of data are stored.

AUTO is a two point calibration. The calibration proceeds in two steps, AutoCal 1 is an offset calibration and AutoCal 2 is a slope calibration. Auto Cal provides automatic solution recognition of the calibration solutions used for each measurement in accordance with the following list:

1. pH Calibration Buffers (US Standard), pH 4.01, pH 7.00 and pH 10.00 (see Appendix A)

2. ORP Calibration Solutions: Quinhydrone saturated: pH 4.01= +89 mV, pH 7.00= +266 mV

3. pIon Calibration Solutions: 1.00, 10.00, 100.0 ppb, ppm, ppt

(thousand)

4. Dissolved Oxygen: Zero ppm (Sodium sulfite, Na2SO3 in water), Air saturated water, 8.25 ppm

Any two solutions can be used for AUTO calibration however if solutions other than those listed above are used for calibration then the calibration values must be entered manually.

STAND is standardization, a single point calibration. Standardizations are typically used to adjust the process reading to agree with a laboratory determined “grab sample” reading.

MANUAL is a data entry screen. Manual calibration allows the user to enter a concentration with the corresponding mV value and a slope for an electrode. Laboratory generated calibration data for an electrode can be input to a remote analyzer where calibration is difficult or impractical.

TEMP allows the displayed temperature to be trimmed to agree with actual process temperature.

3.2.3 CONFIG (CONFIGURATION MENU)

Four options are available in the Configure Menu, XMTR, SENSOR, LOAD DEFAULT and Dampen.

XMTR enters the Transmitter Configuration menu.
