Online Operation Using Menus

7.4 Data Entry

Data Entry lets you enter or revise data online. Choices available depend on installed options and enabled features (see “Enable Features” in Section 4.19).

Edit Alarm Setpoints

Select this item to display a list of alarms and their setpoints. If the setpoint is a numeric value, it can be changed on this display using the Up Arrow, Down Arrow and Left Arrow buttons. If it is programmed as a parameter, it cannot be changed here.

Edit Constants

Select this item to display or change a list of all constants in the instrument. To change a value, use the Up Arrow, Down Arrow and Left Arrow buttons.

Force Discrete Inputs/Outputs

Select either of these items to display or force the status of any discrete.

The STATE indicates ON or OFF. FORCE/RELEASE indicates if the discrete is forced or released (unforced). To force a discrete, select FORCE ON or FORCE OFF. To release a forced discrete, select RELEASE. Adjust with Up Arrow and Down Arrow. Press Enter to enter the changes. Press Menu to leave the menu.

Adjust Analog Inputs

If the AI point has been configured with a pyrometer range, the Input Adjust is applied as a multiplier (equal to the newly entered value divided by the actual measured valued at the time that the adjustment is entered). In this case, the Value Adjust is referred to as an “emissivity” adjustment. If the AI point has been configured with any other range, the value adjust is applied as a bias (equal to the newly entered value minus the actual measured value at the time that the adjustment is entered).

All points on the display which are currently adjusted will have a Value Adjust Indicator (*) beside the value.

To adjust a value, select the desired AI and press Enter. Press Enter to highlight the value then use the Up Arrow, Down Arrow and Enter buttons to change the value on the display. The value can be changed to any value within the programmed limits of the AI.

To remove the value adjustment, set the value to OFF. The AI will display its current value and the indicator (*) will be removed.

Set Analog Outputs

This menu item will appear if the optional analog outputs are installed. It lets you adjust various analog output parameters.

Two output types are available: current output (CAT) and time proportion/duration adjusting (DAT).

Failsafe Value

Enter a value of 0 to 100% or an analog parameter for the initial output. This is the initial output on “cold start”. If the failsafe value is set to off, the output will go to 0.

Impulse Time

For DAT outputs, use the Up Arrow, Down Arrow and Enter buttons to adjust the impulse time. Impulse time must be ≥ 1 second. Impulse time is the cycle time for on and off cycling of the output. For example, an impulse time of 150 seconds will cause the output to be on for 75 seconds and off for 75 seconds when the input source is at 50.
