Operating Information
WARNING
Personal injury or property damage may result from fire or explosion if power is applied to the transducer with the cover
removed in a hazardous area.
If the transducer is installed in an application where explosion‐proof classification is required, perform the following steps
(prior to removal of the transducer cover) when any procedure in this section requires removal of the cover:
D
Disconnect the electrical signal from the transducer.
D
Remove the transducer to a non‐hazardous area.
D
Perform procedures as described in this section.
D
Reinstall the transducer, and ensure the cover is secured before turning on the electrical signal.
Adjustments
Adjust the filter regulator to provide the proper supply pressure to the transducer, then adjust the transducer span and
zero (see figures 4 and 5) to match the application requirements and be within specifications.
