GND TOC TDM
Range: 0.50 to 20.00 in steps of 0.01
Default: 1.0
This setting provides selection for Time Dial Multiplier by which the times from the
inverse curve are modified. For example if an ANSI Extremely Inverse curve is selected
with TDM = 2, and the fault current was 5 times bigger than the PKP level, the operation
of the element will not occur before an elapsed time from pickup, of 495 ms.
GND TOC RESET
Range: Instantaneous, Linear
Default: Instantaneous
The "Instantaneous" reset method is intended for applications with other relays, such as
most static relays, which set the energy capacity directly to zero when the current falls
below the reset threshold. The "Timed" reset method can be used where the relay must
coordinate with electromechanical relays.
OUTPUT RELAY 3 to 6
Range: Do not operate, Operate
Default: Do not operate
Any or all of the output relays 3 to 6 can be selected to operate upon Ground TOC
operation. The selection of relay outputs operation is available no matter whether
Latched Alarm, Alarm, or Trip function is selected.
BLOCK 1/2/3
Range: Off, Contact Input 1 to 10[8], Virtual Input 1 to 32, Remote Input 1 to 32, Logic
Elements 1 to 16
Default: Off
Three blocking inputs are provided in the Ground TOC menu. When any of the selected
blocking inputs - Contact input, Virtual Input, Remote Input, or Logic Element - turn on,
the ground TOC function is blocked.
