Description

During calibration it was found that the maximum amount of flow occurred with the command output at only the middle (midpoint) of the range. This indicates that there is incorrect equipment installed, or the equipment is faulty. This might also indicate a large air leak.

Remedy · Remède

Check that the I/P transducer is within the correct right range. If not, replace it. Check that the booster has the correct ratio, typically 1 to 1. If the alarm log also has a leak alarm, follow the remedies for that alarm. If this equipment must be used, reduce the Max. control value for this parameter by about 20%.
