Relay will show the currently used inverse delay curve on the
local panel display.
Programmable inverse time curves
(only for I
dir
> and I
dir
>>):
The [current, time] curve points are programmed using
VAMPSET. There are some rules for defining the curve points:
• configuration must begin from the top most line
• line order must be as follows: the smallest current (longest
operation time) on the top and the largest current (shortest
operation time) on the bottom
• all unused lines (on the bottom) should be filled with ‘1.00
0.00s’
