O: With setting
• An arbitrary output can be set at each of output terminal 1, output terminal 2, and output
terminal 3. This setting can perform alarm outputs, pulse outputs, 3-STATE outputs, etc.
[Setting Items]
OFF, pulse output, open-phase output, opposite-phase output, measurement blocks 1/2,
and alarm output (Default: OFF)
Note. PGR1C, PVS1C, VAU1B, and VAU1B are provided with two output terminals and
CTD8E is provided with one output terminal.

Each time the integrated power amount reaches a set pulse output unit, pulse is output from the
terminal set by the output pulse setting.
As the power amount increases, the integrated power amount increases, and pulse output cycles
(intervals) become shorter. As the power amount decreases, the integrated power amount
decreases, and pulse output cycles become longer.
Output pulse cycles can be obtained by the following calculation formula.
Pulse output cycle [s] = 3600 [s]/(Power [W]/Pulse output unit [Wh])
The calculation method of pulse output cycles is described taking an example.
Example:
When input power is 200 k[W] and pulse output unit is 10 k[Wh] in 3-phase 3-wire, output pulse
cycle = 3600 [s]/(200 k [W]/10 k[Wh]) = 180 [s] is obtained. If the status with input voltage of 10
k[W] is continued for an hour, passage of an hour (3600 s) gives 10 k[Wh]. If an input of 200 k[W]
sets the pulse output unit to 10 k[Wh], 200 k[W]/10 k[Wh] = 20 pulses are output for an hour, and
the cycle is as follows: 3600 [s]/20 pulses = 180 [s]. For the output pulse, one pulse is output (ON)
every 180 [s].

When the cycle is shorter than the pulse width, or when the next output is turned ON
immediately after the output is turned OFF, OFF time of 100 ms is given.
If OFF time is short, count error may occur due to scan time such as PLC. Set an appropriate
pulse output unit.
