Setting Default Range Incr.
Vert. multiplier - phase
delay curve
1.00 0.10 - 2.00 0.01
The Vert. multiplier - phase delay curve setting shifts the phase delay curve in time, by the entered
multiplier, if Delay curve - phase (No. 10) is programmed with a recloser or user curve. If no
particular multiplier is desired, set Vert. multiplier - phase delay curve equal to 1.00.
• If Delay curve - phase (No. 10) is programmed with a US (U1-U5) or IEC (C1-C5) curve, Vert.
multiplier - phase delay curve is hidden and nonoperative. The preceding Time-dial - phase
delay curve (No. 10) subsetting provides the US and IEC curves with an effective vertical
multiplier, instead.
• This setting has no multiplying effect on the Constant time adder - phase delay curve and Min.
response time - phase delay curve settings. They all operate independently.
• This setting is hidden and set to 1.00 if Complex delay curve - phase is set to N and Delay
curve-phase (No. 10) is programmed with a recloser or user curve.
Setting Default Range Incr.
Min. response - phase delay
curve
0.00 0-60.00 cycles 0.25 cyc.
The phase delay curve can trip no faster than the Min. response time - phase delay curve setting.
If the Min. response time - phase delay curve setting is set equal to zero (0), it has no effect on the
phase delay curve. If the Min. response time - phase delay curve setting is set equal to 15 cycles, for
example, the phase delay curve cannot trip on the portion of the curve that is faster than 15 cycles - the
phase delay curve effectively flattens out at 15 cycles.
• This setting is hidden and set to zero (0) if Complex delay curve - phase is set to N.
No. Setting Default Range Incr.
28 Complex delay curve -
ground
N Y/N
The Complex delay curve - ground setting enables the following three settings for the ground delay curve, if
set to Y.
• This setting is hidden and set to N if Delay curve - ground (No. 11) is set to OFF.
Setting Default Range Incr.
Const. time adder - ground
delay curve
0.00 0-60.00 cycles 0.25 cyc.
The Const. time adder - ground delay curve setting adds a constant time to the ground delay
curve, if set other than 0 cycles.
• This setting is hidden and set to zero (0) if Complex delay curve - ground is set to N.
