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).

If this display was active at power down, it will be active at powerup.

2)The upper display shows the limiter 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 second limiter 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 shutdown condition while the lower displays shows “t.” If no shutdown condition was detected, 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 measured value detected during the last shutdown condition while the lower display

shows "Ph.". If no shutdown condition was detected, the upper display will show “- - - -”. This information is not available if C1 = HI.Lo. The information is lost at power down and at powerup the device will display the process variable.

NOTE: When the shutdown condition was generated by an input fault condition, the upper display will indicate “m.Err”

6)The upper display shows the minimum mesured value detected during the last shutdown condition while the lower display shows "PL.” If no shutdown condition was detected, 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: When the shutdown condition was generated by an input fault condition, the upper display will indicate “m.Err”

If, at power off, the device was in shutdown condition and shutdown memoy function is selected (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.
