System Configuration
:
Master --- PMU2A (power two-system)
Slave --- EMU8A (pulse/temperature)
CTD8E (CT expansion)
Purpose
:
Classification of operating signals (condition) for the facilities
of 3-phase 3-wire line.
Extraction of waste in the electric power of single-phase
2-wire
Measurement of electric power in facilities of each line.
Setting switch
:
Set the Pin no. 2 of DIP switch to OFF (CompoWay/F) across
the entire system.
Using the rotary switch, set the slave ID.
EMU8A (pulse/temperature) --- 5 (to use event input for
3-STATE)
CTD8E (CT expansion)
--- 1 (Because the setting range
of slave ID is from 1 to 4)
Unit no.
:
PMU2A
--- 01 (Because the setting range of unit no. is from
00 to 99.)
EMU8A
--- 02 (Because the setting range of unit no. is from
00 to 99)
CTD8E
--- 03 (Because the setting range of unit no. is from
00 to 99.)
* A unit no. is assigned by higher equipment (example: PC) to identify units from each other.
