Mitsubishi Electric AE-200A Instruction Book page 36

(A) When the Peak Cut method [Demand-Input PLC] is selected
(1) In the [IP Address] field, enter the IP address of the Demand-Input PLC.
(2) When using the Demand-Input PLC for the first time, click [Initialize] to initialize its internal memory.
Note: Do not initialize the Demand-Input PLC after the operation has begun, for it will clear all operation data.
(3) In the [Controlled AE] field, enter the IP addresses of the AE-200/AE-50/EW-50 units to which the demand
level signal is sent. Up to 10 IP addresses can be registered.
(4) In the [Temperature difference between set point and inlet] section, a temperature differential can be set to
between 3 and 9 as necessary. The Peak Cut control setting that corresponds to the control level 0 will be
disregarded for the indoor unit groups in which the temperature difference between the set temperature and
the room temperature is greater than the specified temperature differential.
Note: The Peak Cut control setting that corresponds to the control levels 1 to 4 will be effective regardless of the
temperature differential setting.
(B) When the Peak Cut method [Electric Amount Count PLC] is selected
(1) In the [IP address] field, enter the IP address of the Electric Amount Count PLC.
(2) When using the Electric Amount Count PLC for the first time, click [Initialize] to initialize the internal memory.
Note: Do not initialize the Electric Amount Count PLC after the operation has begun, for it will clear all operation data.
(3) In the [DI Board] field, select the DI board number to which the watt-hour meter is connected, and the
terminal number. If the watt-hour meter is connected to terminal 2 on a DI board 1, select 1-2.
Note: Select a DI board number 1 or 2, and select a terminal number/code between 0 and F.
(4) In the [Pulse Unit] field, enter the pulse value that the watt-hour meter outputs. Set the pulse value according
to the watt-hour meter to be used.
Important: Check the watt-hour meter readings several times on the hour and the half-hour. Then, be sure to check
that the increase in the watt-hour meter reading for each 30-minute period and the average electric power
consumption in the same period that the Peak Cut function is used are the same amount.
The average electric power for the period that the Peak Cut function is used can be checked on the Trend
Graph display or in the CSV file that can be downloaded from the Trend Graph display. The Trend Graph
display can be found on the Peakcut Control Status screen, accessible via the Web Browser for System
Maintenance Engineer. Refer to the Instruction Book (Web Browser for System Maintenance Engineer) for
details.
(5) In the [Control levels] section, the range of the electric power must be set for each control level. For control
level 4, enter the value that is 10% to 15% below the maximum power demand (average electric energy that
cannot be exceeded in any 30-minute period). For control levels 3 to 0, enter the value that is decreased
by about 10% from the set value of the previous control level. (The screenshot above shows the setting
example of the maximum demand of 200 kW.)
Note: The optimum setting depends on the system configuration of the electric equipment and on the indoor environment in
each building. Determine the appropriate values accordingly.
