Normal Display Mode

On powerup the device starts in the "Normal Display Mode."

By pressing the or key, it is possible to change the displayed information; therefore, one of the following display modes can be selected:

1)The upper display shows the measured value while the lower display shows the "Pu" (Process variable)

2)The upper display shows the setpoint threshold while the lower display shows "Su." If this display was active at power down, it will be active at powerup.

3)The upper display shows the setpoint1 threshold while the lower display shows "S1." This information is available only if C1 = Hi.Lo If this display was active at power down, it will be active at powerup

4)The upper display shows the total time (hh.mm) of the last reset condition while the lower displays shows “t.” (if no data is available, the upper display will show

"- - - -" ). The information is lost at power down and at powerup the device will display the process variable.

5)The upper display shows the maximum value of process variable detected during the last "reset" con- dition while the lower display shows "Ph." (if no data is available, the upper display will show “- - - -” ). This information is not available if C1 = Lo. The information is lost at power down and at powerup the device will display the process variable.

NOTE: In case the reset condition was generated by a fault condition in the measure variable, the upper display

will indicate "m.Err"

6)The upper display shows the minimum value of the process variable detected during the last "reset" con- dition while the lower display shows "PL.” (if no data is available, the upper display will show “- - - -”) This information is not available if C1 = Hi. The information is lost at power down and at powerup the device will display the process variable .

NOTE: in case the “reset condition” was generated by a fault condition in the measure variable, the upper

display will indicate "m.Err"

At powerup the display will show the process variable unless otherwise stated in one of the above display options

If, at power off, the device was in reset condition and configured to save it (C4 = 0), and/or it was programmed for manual reset at startup (C3 = 1), then at the next power up the lower display will be flashing.
