Warnings and errors
Via the three-coloured status display, internal instrument warnings (yellow) and errors (red) are shown, see chapter 5.6
"Colour codes of status display". An extended error diagnosis is possible via IO-Link.
16
Should a failure occur, media with extremely high temperature and under high pressure or vacuum
may be present at the instrument.
For these media, in addition to all standard regulations, the appropriate existing codes or regulations
must also be followed.
Wear the requisite protective equipment.
Possible cause
Cable break
No/wrong supply voltage
Wiring error or switching of switching logic
Mechanical overload caused by overpres-
sure

Moisture has entered
Measure
Check the continuity
Rectify the supply voltage
Observe the pin assignment
Check the output configuration
Replace instrument; if it fails repeatedly,
contact the manufacturer
