B
A = Parameter 1401 RELAY OUTPUT 1 (1402 RELAY OUTPUT 2) value is
SUPRV2 OVER
B = Parameter 1401 RELAY OUTPUT 1 (1402 RELAY OUTPUT 2) value is
SUPRV2 UNDER
OVER or
SUPRV1 UNDER or
SUPRV1
Note! Case LOW
≤ HIGH represents a normal hysteresis.
Case A: Is for monitoring when/if the supervised signal exceeds a given
limit.
Case B: Is for monitoring when/if the supervised signal falls below a
given limit.
