The pressure transmitter may only be started up after it has been completely installed and
checked by appropriately qualified personnel. Switch on the operating voltage for start-up. Prior
to applying the operating voltage, it is essential to check the correctness of the process
connection and the electrical connection and ensure that the impulse line has been completely
filled with the process medium. Then proceed with start-up.
Prior to applying the operating voltage check that
1. the process connection fits properly
2. the signal and, if necessary, supply lines are properly connected
3. the impulse lines are completely filled with the process medium
After connecting the differential pressure transmitter to the power supply or after voltage
