4.1.3 General functions
(1) Setting of operation voltage
The operation voltage settings for undervoltage and overvoltage elements are indicated with voltage
values [V].
When the setting "Lock", the elements selected are locked for operation.
(2) Setting of operation timer
The operation time settings for undervoltage and overvoltage elements are indicated with second [s].
(3) Operation display
For undervoltage element, when the input voltage becomes less than the operation setting, the
corresponding operation indicator LED will blink to allow you check the starting value.
For overvoltage element, when the input voltage becomes larger than the operation setting, the
corresponding operation indicator LED will blink to allow you check the starting value.
The LED lamp will come on as soon as an operation output is made when a period of operation time
has elapsed.
The operation indicator LED has been set to "self-hold" in the factory. This setting can be freely
changed to "auto reset".
With the "self-hold" setting, data of the latest operation indication will be stored in the internal memory
even if the auxiliary power supply runs down.
The data stored will be cleared when the "indicator reset" switch is pressed.
Up to latest five phenomena can be stored and displayed as a history record. (Older data than the
latest five phenomena will automatically be cleared).
