3.7 Using D/A Output

Current integration, active power integration
Level output (fixed to STD.5) functions as follows for current integration and active power integration.
(The default f.s. setting is 5 k [Ah/ Wh])
Time average current/ active power
Fixed to STD.5 (5 Vf.s.)
f.s.: 5 m/ 50 m/ 500 m/ 5/ 50/ 500/ 5 k/ 50 k/ 500 k/ 5 M/ 50 M/ 500 M/ 5000 M [Ah/ Wh]

-5 V at -f.s.

Level output for current integration and active power integration changes to +5 V or -5 V at a
whole-number multiple of the selected f.s. value. When the current integration or active power
integration value exceeds the selected f.s. value, level output changes to 0 V, and then voltage
output continues from 0 V depending on the integrated value.
Example: If the f.s. value in the above figure is 5 kWh
Level output changes to +5 V or -5 V at whole-number multiples of +5 kWh or -5 kWh (5, 10,
15, etc.).
(1) +5 kWh
(2) +10 kWh
(4), (6) -5 kWh
(3), (5) When integration stops, the output voltage at that point in time is held. When integration is started
in that state, the voltage continues to change from the held output voltage.
(7) When integration stops, level output is in the integration stopped state. The output voltage at this
point is held.
(8) When integrated values are reset, the output voltage changes to 0 V.
When integration is started in that state, the voltage changes from 0 V according to the integrated
value and is output.
STD.2 (2 Vf.s.) settings STD.5 (5 Vf.s.) settings
The f.s. for level output for time-average current and time-average active power is the current or active power
measurement range, and level output changes to +9 V at ±450%f.s. when using STD.2 (2 V) or at ±180%f.s.
when using STD.5 (5 V), voltages in excess of that value are not output.
