Pulse Signal Input Function - Mitsubishi Electric AE-200A Installation Manual

9-2. Pulse signal input function

Using pulse signals directly input from metering device such as watt-hour meter, billing data and energy
management data will be obtained based on the cumulative number of pulse signal input.
Note
To input pulse signals directly from the metering device to the AE-200, use the connector connected to the AE-200. (A
precision screwdriver for M1 screws is required.)

*1 A built-in PI controller on the AE-200 cannot be used for an apportioned electricity billing function. Use a built-in PI controller on the AE-50 or
EW-50.
*2 Using a PI controller (PAC-YG60MCA) is recommended instead of a built-in PI controller on the AE-50/EW-50 when using an apportioned
electricity billing function. (Discrepancies may occur between the built-in PI controller reading and the actual electric energy because the
pulse input cannot be obtained during the AE-50/EW-50 power failure, shutoff process, and software update.)

Note
The total length of the lead wire and extension cable should not exceed 100 m (328 ft). (Use an extension cable of 0.3 mm
or thicker.)
Cut the excess cable near the connector, and insulate the end of the unused cable with tape.
Do not run the signal input cable adjacent to the M-NET transmission and power cables. Do not let the cable form a loop.
Peel off the sheath to 6 ±1 mm (4/16 ±1/16 in) from the end, and securely insert the cable into the terminal.
Leave adequate slack in the cables so that the weight of them will not strain the terminal connectors. Use cable clamps or
trunk terminals as necessary.
