Emerson Micro Motion 5700 - Batch Problems; Batch will Not Start; Valve Does Not Operate; Valve Operation Is Backwards

5. Ensure that reference temperature and reference pressure, if applicable, are configured correctly.
6. Ensure that the selected API table is appropriate for the process fluid.
17.3 Batch problems
17.3.1 Batch will not start
Cause
• Previous batch not ended
• Valve is closed but the transmitter is detecting flow
• No discrete output configured for batch control
• For two-stage batching, primary and secondary valves are not configured
Recommended actions
1. End the batch.
2. Check for two-phase flow.
3. Verify the zero.
4. Verify the cutoffs.
5. Set up a channel to operate as a discrete output, and configure it for batch control.
6. For two-stage batching, configure the primary and secondary valves.
17.3.2 Valve operation is backwards
Cause
• Discrete Output wiring is incorrect
• Discrete Output polarity is reversed
Recommended actions
1. Verify the wiring between the Discrete Output and the valve. The ON signal must open the valve.
Perform a loop test.
2. Change the setting of Discrete Output Polarity.
17.3.3 Valve does not operate
Cause
• Discrete Output wiring is incorrect
• Discrete Output channel is set up for internal power
Recommended actions
1. Verify the wiring between the Discrete Output and the valve. The ON signal must open the valve.
Perform a loop test.
2. Ensure that the channel is wired and configured for external power.
