4.3.6 Overcurrent operation
The controllers are designed for two overcurrent modes:
ƒ 5-s-cycle c
– 0.5 s load period with peak current
– 4.5 s recovery time with limited current
ƒ 3-min cycle d
– 1 min load period with peak current
– 2 min recovery time with limited current
A load period must be followed by a recovery time. During the recovery time the current
must not exceed the value given.
The values given refer to the rated output current I
