Schneider Electric Pressure Transmitter IDP50S-F

De-energize transmitters before removing threaded housing covers

Ensure no flammable or combustible atmosphere is present before disconnecting equipment

Remove the vent plug by unscrewing it counterclockwise

Clean the angled sealing surface on the housing

Lubricate the o-ring and the threads on the new plug with silicone lubricant

Install the new plug into the housing by screwing it clockwise

Torque the new plug to 0.9 ±0.02 N-m (8 ±0.2 lbf-in)

Verify the installation of the new plug

Access the transmitter’s top level menu

Navigate to TST DSP and initiate test

Step through the five test patterns

Transmitters with the Optional Display

Unlatch the external zero button by turning it 90 degrees counterclockwise

Relatch the external zero button by turning it 90 degrees clockwise

Set or reset using the optional display

Apply zero pressure to the transmitter or use a bypass valve to equalize pressure

Press the external zero button until the display reads CAL AT0, then release

Apply the lower range value (LRV) pressure to the transmitter

Press and hold the external zero button until the display reads CAL LRV, then release

Perform One-Point Calibration at LRV

Perform one-point offset calibration at LRV

Is the transmitter output stabilized at the final operating temperature?

Rezero the transmitter output if necessary

Are underrange and overrange output values extending beyond 4 and 20 mA?

View the total days the transmitter has been in service using the 1 Device Setup > 2 Calibration > Time in Service Meter menu selection.

View the user days since the last reset using the 1 Device Setup > 2 Calibration > Reset User Days menu selection.

Reset the user days to zero if necessary.

Perform a two-point calibration if FoxCalTM is enabled.

Rezero the transmitter output once it has stabilized at the final operating temperature.

Check underrange and overrange output values to ensure they extend beyond 4 and 20 mA, respectively.
