S600
Impermissible electronics
temperature
Temperature of the electronics in the
non-specified range
Check ambient temperature
Insulate electronics
Use instrument with higher tempera-
ture range
S603
Impermissible operating volt-
age
Operating voltage below specified
range
Check electrical connection
If necessary, increase operating voltage
S605
Impermissible pressure value
Measured process pressure below or
above the adjustment range
Check nominal measuring range of the
instrument
If necessary, use an instrument with a
higher measuring range
