[E0] display of the 7-segment LEDs of the EcoWebServerIII with demand control function.

[E0] display of the 7-segment LEDs of the EcoWebServerIII with demand control function (Model: MES3-255C-DM-EN).
What is the cause?

Answer

Where power is not connected to a power frequency input terminal (V1, V2 terminal of demand control unit) of the EcoWebServerIII with demand control function, [E0] display of the 7-segment LEDs is ON.
Connect power to the power frequency input terminal even when demand monitoring is not performed.
It is possible to perform transition wiring from an auxiliary power input terminal (L, N terminal of the power section) to the power frequency input terminal. When performing demand monitoring, do not use power supply (like UPS, SAG) other than commercial power supply to the power frequency input terminal. Since the clock of the demand control unit is synchronized with power frequency, the clock of the demand monitoring section supplied power other than commercial power may cause time lag with the clock of a transaction meter.
