Configure A Do For Valve Control Using Prolink Iii - Emerson Micro Motion 5700 Configuration And Use Manual

Configuration and Use Manual
MMI-20025166
Procedure
1. Verify the wiring between the selected channel and the valve.
2. Configure the selected channel to operate as a Discrete Output.
a) Choose Menu > Configuration > Inputs/Outputs.
b) Set Channel B, Channel C, or Channel D to operate as a Discrete Output.
c) Set Power Source to External.
3. Configure the selected channel for valve control.
a) Choose Menu > Configuration > Inputs/Outputs.
b) Select the discrete output to be used for valve control.
c) Choose I/O Settings.
d) Set Source to Batch Primary Valve.
e) Set Polarity to match the wiring.
The ON state of the Discrete Output must open the valve, and the OFF state must close the
valve.
f) Set Fault Action so that the valve will be closed if a fault occurs.
The appropriate setting is either Upscale or Downscale. The setting to use for your installation
depends on your valve type, your wiring, and your setting for Polarity.
4. Optional: For two-stage batching, assign one of the discrete outputs to the secondary valve.
You can also assign one of the Discrete Outputs to a pump when the batcher is configured for single
stage or two stage.
