Jumper and Switch Settings

SPA jumper and switch settings are shown in Figure B-3. If the SPA with HART was factory-configured by Emerson Process Management for operation with your OCX 8800, jumper and switch setting adjustments are not required. However, you may use the following procedure to verify that the jumper and switch settings are correct. Adjust or verify jumper and switch settings as follows:

Electrostatic discharge (ESD) protection is required to avoid damage to the SPA electronic circuits.

1.Refer to Figure B-3. Turn the SPA over and slide the access cover out. Before changing any jumper or switch position, take adequate precautions to avoid an electrostatic discharge.
