Detection item (Self diagnostics item)
Contact composition
Contact capacity
(1) Watchdog timer
(2) RAM check error
(3) A/D conversion error
At the case of error detection and not applying for
auxiliary supply, an output is ON.
It becomes OR output of a detection item.

External
operation
input
Number of circuits 2 circuits, A function (four types) is changed by setting.
Function
Four types of following functions can be operated by adding a voltage signal
from the outside in addition to switch operation.
Alarm reset
Alarm output is reset (output OFF).
Maximum / Minimum
value reset
The maximum/minimum value is reset (it updates to the instantaneous value at
the time).
Measurement
factor change
The measurement display element of the main monitoring is changed.
Phase change
Phase/line display of all the current/voltage currently displayed is changed.
Minimum operation
pulse width
300ms ，Continuation applying is possible.
Rated input
Input rating becomes the same as that of auxiliary supply.
(1) AC100/110V 0.4VA，AC200/220V 1.4VA，DC100/110V 0.4W AC DC two ways.
Contact capacity：About 3mA (AC,DC100/110V) ，About 6mA (AC200/220V)
(2) DC24V 0.3W，DC48V 1.2W
Contact capacity : About 10mA (DC24V) ，About 20mA (DC48V)
Note(
27
) 2 outputs combination is possible, for pulse output and alarm output and
CPU error output. (CPU error output is 1 point only)
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, please use the thing with about
1mA of minimum application loads.
