An apparatus provides operator feedback in response to opening or closing of a valve or coupling. The apparatus comprises data storage means for storing at least one recommended opening or closing event of the valve, sensing means for sensing operator actuation of the valve or coupling and processing means for comparing the sensed actuation of the valve or coupling against the recommended opening or closing event of the valve or coupling in real time or near real time. At least one operator feedback signal based on the comparison is outputted. |
