●
Soft output characteristic
For operation in parallel, the output voltage decreases with increasing output current.
This
means that for full output current the highest output voltage can normally no longer
be
attained.
●
System start characteristics
In order to reduce the load on the overall SITOP PSU8600 power supply system as a
result of simultaneous switch-on current peaks of the loads at the various outputs, an on
delay between the outputs can be selected when switching on.
When the on delay is activated, the outputs are sequentially switched-on with a 25 ms or
100 ms delay time between the outputs, or load optimized.
When the variable on delay is activated, you can assign individual on delay times to the
individual outputs.
●
Threshold for system output current prewarning
When changes are made, the prewarning threshold for the summed current allows you to
quickly check the utilization of the overall system. This is especially of interest when
expanding the system. As a consequence, using the prewarning threshold increases the
operational reliability.
Enter a value of "0 %" to deactivate the prewarning threshold.
●
Dead time for system output current prewarning
An alarm for the prewarning threshold for the total current is only initiated if a continuous
system overload occurs, which is longer than the set dead time.
●
General prewarning threshold for individual output current in MANUAL mode.
Here, it is possible to define a common threshold value for all outputs, above which an
alarm is output.
Enter a value of "0 %" to deactivate the prewarning threshold.
●
Dead time for alarm message 'Input voltage outside permitted range'
A buffer mode alarm is only initiated if the power continuously fails for a time that is
longer
than the set dead time.
Procedure
1. Select the "Hardware configuration" menu.
2. Select submenu "Device configuration".
3. Select entry "PSU8600".
4. Make the required settings in the editor area.
5. Load the data to the device, see Chapter "Loading the configuration (commissioning)
(Page 277)".
You can find additional information on configuring the outputs in Chapter "Operator control at
the device (Page 79)".
