7
Application with automatic supervision of the automatically calculated factors
When the NTRL CUR UNBALACE 1 AUTO-SET command is switched to “Auto,” the process of calculating and applying the
balancing coefficients is fully automatic. Typical applications require setting this function to “Auto” with the bank de-
energized, then subsequently energizing the capacitor bank. After the function is set to “Auto,” it expects to read valid input
signals as a result of bank energization within the display flash message time duration to calculate and apply factors.
Otherwise, the function is switched backed to “Disabled.” When the bank is energized and the five-cycle timer of the 60N
function expires, the balancing coefficients are calculated and automatically applied. After the new balancing factors are
applied, the auto-setting function switches automatically from “Auto” to “Disabled,” and the 60N element becomes
operational. In essence, when in “Auto” mode, the confirmation command executes automatically immediately after the
balancing values become available. The C70 does not display the applied coefficients in the “Auto” mode; instead, they can
be viewed in the
SETTINGS menu.
If the supervisory conditions are not satisfied in the “Auto” mode within time defined by the DEFAULT MESSAGE TIMEOUT
setting, the AUTO FAIL message displays and the 60N function starts running with the pre-existing settings for the
balancing factors.
7.1.2 Virtual inputs
COMMANDS VIRTUAL INPUTS
The states of up to 64 virtual inputs are changed here. The first line of the display indicates the ID of the virtual input. The
second line indicates the current or selected status of the virtual input. This status is a state off (logic 0) or on (logic 1).
