Electrical Ground Connections
The transmitter is equipped with an internal ground connection within the field wiring
compartment and an external ground connection at the base of the electronics housing.
To minimize galvanic corrosion, place the wire lead or terminal between the captive
washer and loose washer on the external ground screw. If shielded cable is used, earth
(ground) the shield at the field enclosure only. Do not ground the shield at the
transmitter.
Test Points
The banana plug receptacles (designated CAL) can be used to check transmitter output of
the IDP10-A. Measurements should be 100 to 500 mV dc for 0 to 100% transmitter
output. Refer to Figure 9.
HHT Terminals
As the top terminal is blocked, this transmitter does not communicate with the HHT, PC10,
PC20, HART Communicator, or IFDC.
