*1: The data length will be 8 bits if Modbus is set as the communications protocol.
*2: If Modbus is set as the communications protocol, the number of stop bits will be set
automatically according to the vertical parity.
No vertical parity: 2 bits
Odd or even vertical parity: 1 bit
*3: The conversion coefficient varies with the region. Please check the home page of your power
company. The default setting is the CO
2009.
*4: These addresses are used only for the KM50-E. They cannot be read or written with the
KM50-C.
*5: Always set the LOW threshold to a lower value than the HIGH threshold.
You cannot set the values so that the HIGH threshold is lower than or equal to the LOW
threshold.
*6: Addresses F020 (Active Power Alarm Setting), F043, and F049 have the following relation.
Addresses F020 and F043 (Active Power Alarm Setting (Output Terminal 1)) are for the
same parameter for KM50-C.
Addresses F020 and F049 (Active Power Alarm Setting (Output Terminal 2)) are for the
same parameter for KM50-E.
The same value can be read out with either address setting.
*7: The alarm function is disabled if the upper limit threshold is set to the maximum value or the
lower limit threshold is set to the minimum value.
*8: If 3-ST (KM-E only) is set for the event input, the Three-state Target is changed to NONE. To
set the Three-state Target to something other than NONE, set the Event Input Setting to the
Pulse Input Count or ON Time Measurement before selecting a target.
