Replace the cover and return power to the ECA.
10.4 Error Recovery
In cases of abnormal operation, the following procedure is recommended:
1. First, check all power and process connections to ensure all wiring is secure and properly
connected.
2. Check the internal connections within the ECA.
3. Ensure that the cable connections from the stroke adjustment motor and encoder are
secure and seated properly.
4. Perform a Factory Re-initialization, as previously mentioned in this IOM. This will also
force a new mechanical zero calibration to be performed. The pump motor should be
operating during this process as the ECA will adjust stroke to re-locate the zero position.
Ensure that it is safe to operate the pump during this step.
5. Perform a new Analog Input signal calibration
6. Perform a new Analog Output signal calibration
