[IV Product specifications and functions]
○ About the peak cut function
NOTE:
・ When using the peak cut function, please understand that Mitsubishi Electric cannot compensate for any
damages in the event of electricity consumption exceeding the electricity values of the contract as a result
of a control operation setting mistake, failure of an AE-200/AE-50/EW-50, PLC, PI controller, E-Energy,
or demand controller, or other problem.
・ The peak cut control units are the blocks of indoor units and the outdoor units in the
AE-200/AE-50/EW-50 unit.
・ For the peak cut control for the electricity meter which is performed using the counting function of a PI
controller or PLC, the electricity meter to be monitored by the AE-200/AE-50/EW-50 must be one only,
and it can be set for each AE-200/AE-50/EW-50.
Peak cut control cannot be used with air-conditioning units to be controlled by one AE-200/AE-50/EW-50
in a system with two or more electricity meters connected. Furthermore, use version 1.01 or later of the
Electric Amount Count Software when using a PLC.
・ Peak cut control using a peak cut control device (peak cut level contact input method)
This method directly inputs a peak cut level signal to the AE-200/AE-50/EW-50 via an external input
adapter (PAC-YG10HA).
A PLC is not required for this method. The peak cut level monitoring and control commands can be
issued from up to three AE-200/AE-50/EW-50 in addition to the connected AE-200/AE-50/EW-50.
・ Peak cut control using a peak cut control device (PLC method)
The PLC method sends a peak cut level signal from the demand controller to the AE-200/AE-50/EW-50
via a PLC. Furthermore, PLC software (PAC-YG41/42/43/91/92/93ATM) is required.
Up to 10 AE-200/AE-50/EW-50 units can be set. If the number of AE-200/AE-50/EW-50 exceeds 10,
install multiple PLC.
・ For peak cut control (other system method), up to 10 AE-200/AE-50/EW-50 units can be set.
・ Using a PI controller enables peak cut control from up to three AE-200/AE-50/EW-50 in addition to the
connected AE-200/AE-50/EW-50.
○ About apportioned electricity billing
・ The apportioned electricity billing function of the AE-200 and the apportioned electricity billing function of
the TG-2000A cannot be used at the same time. (Electricity apportioning will no longer be able to be
performed correctly.)
