Appendix D – 266 PdP Fieldbus FOUNDATION electronics replacement
In order to perform the replacement of a Fieldbus FOUNDATION electronic module, please follow the steps listed here below:
– Remove the cover of the electronics/display side.
– Remove the display (if installed) and be careful to the plastic clips of the electronic module.
– Remove the 2 fixing screws from the electronic module.
– Extract the electronics from the housing, and disconnect the flat cable that links the sensor primary electronics to the
communication board.
The operation is completed and the device will run with default configuration:
PD_TAG = PI000
ADDRESS = 248
– Take the new electronics and put the switch 1 in UP position (1) since it
enables the Replacement operation. It must be used in combination with
the SW 2.
– Put dip switch 2 in OFF position (0) selects the Electronics Replacement.
The entire transmitter's configuration data are kept valid in the sensor
memory and copied into the memory of the new electronics once it is
connected.
– Connect the sensor flat cable to the new electronics and insert it into the
housing (be careful with the two in-housing jack connectors).
– Power on the transmitter and keep it powered-on for few seconds (at
least 30).
– Power-Off the transmitter again, and put the switch 1 and 2 in OFF (0)
position.
– Fix the electronics with the two screws.
– Insert the display, (be carefully with the 6 pins connector).
Maybe removing again the electronics from the housing make easier the
connection of the display.
– Mount the display cover again.
