● Caution on the use of external display selection input (option)
External power consumption is 0.4VA at AC110V or 1.4VA at AC220V or 0.4W at DC110V.
In case a relay or a switch is used for power supply supply, please use the thing of about
1mA of the minimum application loads.
Possible to setting one of them. (Alarm 2 circuit setting of each is possible.)
Item
Measurement value ≧ Upper limit setting value,
With a ground fault phase detection display automatic change function.
(In case of detection.)
(Setting of use / not use is possible for a ground fault phase detection
display automatic change function.)
Function
Ground fault phase detection display
：A maximum zero-phase voltage and the minimum phase voltage are
displayed. A maximum zero-phase voltage and minimum phase voltage
update after of zero-phase voltage detection.
After backlight turns on, backlight is off when not operating it for
5 minutes. (At the case of setting in backlight automatic off.)
Setting accuracy ±1.0％ (％ to the value which set a full scale to 150％)
Setting range 5 to 150％ (1％ step) or OFF (not use), Full scale＝150％.
Measurement value ≧ Upper limit setting value, Alarm display and
alarm output. (Detects by the maximum phase)
Function
Measurement value ≦ Lower limit setting value, Alarm display and
alarm output. (Detects by the minimum phase)
Setting accuracy ±1.0％ (％ to the value which set a full scale to 150％)
Setting range 30 to 150％ (1％ step) or OFF (not use), Full scale＝150％.
2 circuits, Function (4 types) is changed by setting.
4 types of following functions can be operated by adding a voltage
signal from the outside in addition to switch operation.
Alarm output is reset (output OFF).
Please refer to "4.3.6 Reset" about operation by the switch.
The maximum value / minimum value is reset (it updates to the
instantaneous value at the time).
Please refer to "4.3.6 Reset" about operation by the switch.
The measurement display element of the main monitor is changed.
Please refer to "4.3.1 Main monitor display-element change" about
operation by the switch.
A phase/lines display of the voltage display is changed.
Please refer to "4.3.2 Phase (between lines) display change" about
operation by the switch.
300ms ，Continuation applying is possible.
Input rating becomes the same as that of auxiliary supply.
(1) AC100/110V 0.4VA，AC200/220V 1.4VA，DC100/110V 0.4W
(2) DC24V 0.3W，DC48V 1.2W
