Fig. 24: Process value display

1:

Standard display as set under [SELd] and [uni]. 
Example: [SELd] = FLOW and [uni] = m/s

2:

Further view. The LED indicates in which unit the current process value is
displayed. 
Example: temperature in °C.

12.2 Reading the parameter setting

u

Briefly press [●].

u

Press [▼] to select the parameter.

u

Briefly press [●].

w

The currently set value is displayed for 30 s. Then the unit returns to the
process value display.

13 Technical data

.

14 Troubleshooting

The unit has many self-diagnostic options. It monitors itself automatically during
operation.

Warnings and error states are displayed even if the display is switched off. Error
indications are also available via IO-Link.

The status signals are classified according to NAMUR recommendation NE107.

If several diagnostic events occur simultaneously, only the diagnostic message of
the event with the highest priority is displayed.

Additional diagnostic functions are available via IO-Link → IODD interface
