Step 6: Energy Saving/Peak Cut Control - Mitsubishi Electric G-50A Technical Manual

9. Step 6: Energy Saving/Peak Cut Control

Here the energy saving control or peak cut control to be performed by G-50A is set.
This setting is essential in conducting the energy saving control or peak cut control.
As this function is optional, the license registration to G-50A is necessary to use.
A different license should be applied to the energy saving control and peak cut control respectively, the
license for your desired usage should be registered.

function can be applied. (Pulse counting software: PAC-YG11CDA, etc. installed)
For the pulse counting software used at peak cut control, employ that Ver. 1.01 or
later.
For the peak cut control, use one set of watt-hour meter for each G-50A.
The peak cut control license contains the function of energy saving control.
Peak cut control is not available in RS-485WHM system.

[Re: Energy saving/peak cut function]
During the use of the peak cut function, any damage such as the exceeding of
power consumption than the contract demand should induced due to the trouble
of G-50A or PLC, such damage will not be indemnified, for which your kind
understanding is requested.
The registration of
