Overcurrent Isek
Output current exceeds the set level
during a particular delay time.
Controller overshooting caused by
set value steps.
Decrease steps of set value ramp.

Overcurrent Isek
Output current exceeds the set level
during a particular delay time.
Strong additional switching on of a
low resistive load produces a cur-
rent peak (result of the output
capacitance).
A temporary voltage drop is reduced by adding an
exter-nal capacitor or a serial in-ductance.
After a consultation with customer support, where
appropriate, increase the delay.

Overcurrent Iprim
The transformer current exceeds the
preset level (Level is dependent on
the temperature).
Controller overshooting by set
value jumps.
Reduce the gradient of the set value ramp.
Decreasing controller parameters.

Overcurrent Iprim
The transformer current exceeds the

Strong additional switching on of a
low resistive load (fast and large
voltage drop).
A temporary voltage drop is reduced by applying
a exter-nal capacitance or serial inductance.
Decrease of controller parameters.
