9.2 System error messages
Caution:
In the event of a serious fault, a flowmeter might have to be returned to the manufacturer
for repair. The procedures on Page 6 must be carried out before you return a flowmeter
to Endress+Hauser.
Always enclose a duly completed “Safety regulation” form. You will find a preprinted
form at the back of this manual.
Type Error message / No. Cause Remedy / spare part
Serious system errors are always recognized by the instrument as “Fault message”, and are shown as a
lightning flash on the display. Fault messages immediately affect the inputs and outputs.
Simulation and positive zero return, on the other hand, are classed and displayed as notice messages.
Also observe the informations on
→ Page 26 ff. and 42.
S = System error
= Fault message (with an effect on the inputs and outputs)
