Running Time

The K7GE-MG has a built-in electrolytic capacitor. The electrolytic capacitor is impregnated with
electrolytic solution that starts to penetrate the sealing rubber from the time of manufacture. As time
elapses, the internal electrolytic solution continues to evaporate, resulting in decreased electrostatic
capacity and deterioration in other characteristics. Over time, the characteristic deterioration of the
electrolytic capacitor prevents the K7GE-MG from being utilized to its full capacity.
The running time function calculates the approximate time until the
K7GE-MG stops functioning at its full capacity due to the deterioration of the
electrolytic capacitor characteristics, based on the calculated level of
deterioration.
AGE indicator will light when the time for the K7GE-MG to stop functioning
is reached. You can use this function as a guideline for K7GE-MG
replacement.
The Running Time function can be selected from the Use Running Time setting parameter. The default
value is OFF (not used). Refer to 5-10 Use Running Time on page 5-21 for the procedure of the Use
Running Time setting parameter.
Regardless of the setting value of the Use Running Time setting parameter, the communications
commands can read the current running time as a proportion of the guideline value.
The running time function provides an indication of when the deterioration of the electrolytic capacitor will prevent the
K7GE-MG functioning at its full capacity. It does not provide information on failures occurring due to other causes.
