[VCHK] Voltage check for auto-re-close function
This function is used in corporation with the function of auto-re-close (ARC). The VCHK checks
voltage and frequency differences between a Bus-bar and Lines, and permits the ARC the
operation.
Control
The control functions are provided for circuit breakers and isolators, other switchgear and
transformers. The user can operate the functions using the human machine interface; the
functions are able to operate together with such as automatic sequence control, interlocking
safeguard function and manual overridden function.
1.2.1
General control function
[L/R] Remote/Local control function
When control of the object device is required, this function allows the selection of the control
command for either local or remote, (dispatch site/control centre) operation.
[LRST] LED reset function
The LRST function can turn off a LED when the LED is lit by tripping.
[GCNT] General pulse counter function
This function can observe a signal, for example the output of a PLC function and counts the
number of pulses for the signal. The total number of pulses counted is recorded.
[MDCTRL] Mode control function
This function enables an interface for test function block (TSET-FB). With this interface, a
mode change command is made within the IED for the TEST-FB.
1.2.2
Control and monitoring application
[SPOS] Single position device function
The SPOS function is used to operate a device including a single-position switch. The SPOS
function consists of (1) status detection, (2) control, (3) event detection, and (4) response check.
[DPSY] Double position device with synchronism function
The DPSY function is similar to the DPOS one; the DPSY function can operate with
synchronization check function.
[SOFTSW] Software switch function
The SOFTSW function can provide scheme switches created by the software.
[OPTR] Operation time reset controller
The OPTR can reset the time values measured in DPOS and TPOS functions.
[TOTALTIM] Total time measurement function
The TOTALTIM can measure ‘operating time’ (i.e., a device-running-time, closing-time,
switching-ON-time, etc.) with a binary signal.
[SYNDIF] Synchronism check between different networks
