OFF<br />
Reduction of the maximum output current<br />
Possible settings: OFF, 85%, 75%, 50%<br />
If a motor with lower nominal power is used, the maximum output current should be adjusted accordingly.<br />
The reduction of the maximum output current also affects the overload-detection!<br />

Auto<br />
Selection of the switching frequency<br />
Possible settings: Auto, 8 kHz, 4 kHz<br />
• Auto (default setting)<br />
In standard operation the HYDROVAR works with a switching frequency of 8 kHz in order to reduce the<br />
noise level. At rising temperature inside the HYDROVAR the switching frequency is decreased to 4 kHz<br />
automatically.<br />
• 8 kHz - Selection with lowest noise level, but without decrease at rising temperature.<br />
• 4 kHz - Reduce the temperature in the HYDROVAR<br />
