Do not install the controller in areas where there are large amounts of oil, steam, organic solvents or corrosive gases (such as ammonia, sulfur compounds or acids), or areas where. To reduce the risk of short circuit, current leakage, electric shock, malfunction, smoke or fire, do not wash the controller with water or any other liquid. To reduce the risk of electric shock, malfunction, smoke or fire, do not touch the electrical parts, USB memory or touch panel with wet fingers.
To reduce the risk of injury or electric shock, before spraying any chemical around the controller, stop operation and cover the controller. To reduce the risk of injury, keep children away while installing, inspecting, or repairing the controller. To reduce the risk of fire or explosion, do not place flammable materials or use flammable sprays around the controller.
To avoid discoloration, do not use benzine, thinner or chemical cloth to clean the controller. When the controller is very dirty, wipe the controller with a well-wrung cloth that has been moistened with water and mild detergent, and then wipe with a dry cloth.

Introduction
Limitations and warnings for AE-200/AE-50/EW-50 BACnet® functions are as follows. 1) Action to take when an error occurs. Immediately carry out repairs to the problem area when a fault related to air conditioning units is detected on the building management system. When sending "ReadProperty" or "WriteProperty" from the building management system to the AE-200/AE-50/EW-50, set the interval to 200 (ms/property) or higher.
Usage (System configurations)
2 A PC (hereinafter referred to as 'Setting PC') is required to make settings for the AE-200/AE-50/EW-50 BACnet® functions. 2 A PC (hereinafter referred to as 'Setting PC') is required to make settings for the AE-50/EW-50 BACnet® functions. 3 When using the dedicated electricity billing function, we recommend that instead of using the built-in pulse input (PI) of the AE-50/EW-50, you use the PI controller for electrical energy metering.
When using the built-in AE-50/EW-50 Pulse Input (PI), please agree to the above restrictions for the customer and then use. 5 To use a distributed electricity billing function and perform date and time synchronization from the building management system, set "Time Master/Sub" to "Sub" on the AE-200 for billing function and synchronize the time from the AE-50/ EW-50 connected to BACnet®. 6 If you use the distributed electricity billing function, connecting M-NET and Pulse Input (PI) to AE-200 for billing function is prohibited.
As a result, BACnet® settings and the "BACnet Connection" license are not required for the AE-200 billing function. LAN2 (BACnet®), M-NET and Pulse Input (PI) cannot be connected to AE-200 for billing function.

Usage (Function specifications)
12 Power for the power meter connected to the pulse input (PI) of the AE-50/EW-50. Refer to the AE-200/AE-50/EW-50 Instruction Book (separate electricity billing function) for details on the separate electricity billing function. The split electricity billing function in the BACnet® function is configured by an accumulator object which stores the electricity and other cumulative values/result values split the cumulative value and the trend log object which reads the accumulator for any fixed time and accumulates value.
Cumulative electric energy from the electric meter, read from the PI controller Cumulative electric energy from the electric meter, read from the built-in pulse input (PI) AE-50/EW-50. It stores the cumulative value of electricity (indoor unit + outdoor unit) for each group. If an AE-50/EW-50 with a built-in pulse input (PI) is used, pulse input will not be possible when the AE-50/EW-50 is stopped, during power outages, or during software updates. This can cause discrepancies between the measurements and the actual electricity used.).
This function is our original electrical energy allocation system that allocates electrical energy using input from electricity meters with a pulse generator function. Rather than directly measuring the electrical energy consumed by each air conditioner, pulses are input based on the air conditioner usage by. It is not a system (or its equivalent) in which the operating electrical energy consumed by each air conditioner is measured directly at the location where the electricity is supplied.
Because this is a distribution method that uses the operation status of the indoor units of the air conditioner, even when the operation time for the indoor units is the same, the amount of electricity consumed may vary depending on the model configuration and status of the operation of external units. The shared electricity may be different when compared to a situation where one electricity meter is assigned to each air conditioner.). Air conditioners still draw power even when stopped, and electricity is distributed to idle air conditioners as standby electricity.
If the electrical power to the AE-200/AE-50/EW-50 and the PI controller is interrupted due to a power failure, but the air conditioner is still running, the electrical energy cannot be distributed correctly. Because the unit price figures for each tenant (energy management block) are rounded when calculating costs, the figures may differ from the total costs for electrical energy. Sub” setting can be made via the Initial Setting Tool, the initial settings web browser, or the AE-200/AE-50 LCD screen.
Mitsubishi Electric assumes no responsibility for improper power distribution due to problems such as power outages or equipment malfunctions.
