Reset curve type
Supported by
51P 50P-1/2 Note
(1) Immediate x x Available for all reset

(2) Def time reset x x Available for all reset
time curves
(3) Inverse reset x x Available only for ANSI
and user programmable
curves
The Type of reset curve setting does not apply to 50P-3 or when the DT
operation is selected. The reset is purely defined by the Reset delay time
setting.
