5 Settings
Factory setting The trimmer is set to approx. 20 %.
The signal output provided is a floating contact or an optocoupler, depending
on the extra code.
Type: relay
Type:
optocoupler
In the case of a load fault, the floating contact drops out, or the collector-
emitter path of the optocoupler goes high-resistance.
The signal output is also active if the maximum temperature of the converter is
exceeded (overheat), if the safety cut-out in the power section has been
triggered or if the semiconductor fuse has blown (fuse).

The smallest change in resistance that can be detected is 5 % of
the nominal load resistance.

The functions „SIC voltage reserve exhausted“ or „Current limit
active“ can also be applied to the signal output if they are activated
as described in the following sections:
v Chapter 5.8.2 „SIC voltage reserve (SIC reserve)“
v Chapter 5.10 „Setting the current limit (max. current adjust)“
Jumper setting Response
Underload detection
Overload detection
H
The total and partial load failure monitoring (underload) also allows
overload monitoring. For this purpose, both jumpers on the pin
strip X106 must be turned through 90°.
