4.1 Display
The 854 ATG has an LCD display consisting of 2 rows of 16 characters each.
On the display, one of several formats will appear, depending on the status of the XPU(-2).
Immediately after power on the display is blank. Once the power is stable for 20 seconds, the display will
show its initializing message.
If initializing of all processors is successful, the display will switch to its default display format, which is
programmable with item DF.
The possible display formats are:
A level and temperature F pressure P1
B level H pressure P3
C average gas temperature I average servo density
D average product temperature J analog level output
E HIMS density K water level from external HART probe (only with XPU-2)
Refer to Appendix D for an overview of the different display formats.
