10. Trouble shooting
Warning!
Open pressure connections only after the system is without pressure!
■
Take precautions with regard to remaining media in removed transducers. Remaining media in the
■
pressure port may be hazardous or toxic!
Remove the transducer from service and mark it to prevent it from being used again accidentally, if it
■
becomes damaged or unsafe for operation.
Have repairs performed by the manufacturer only.
■
Do not insert any pointed or hard objects into the pressure port for cleaning to prevent damage to the
diaphragm of the pressure connection.
Please verify in advance if pressure is being applied (valves/ ball valve etc. open) and if the right voltage supply and the right
type of wiring (2-wire/3-wire) has been chosen?
