Data
Description
Data type
4 = StartupDelay
Variable
Variable on delay: De-
pending on the parame-
terized delay time,
outputs are activated after
the supply voltage is
switched on.
Soft Output
Characteristics Output
1 (0/255)
Soft output characteristic of output 1 of the SITOP PSU8600 is activated. Unsigned8
Ithreshold (0-100%) Prewarning threshold for the actual system power, referred to the rated power
of the power supply system.
Unsigned8
Reset Reset all outputs: Resets the automatic overload shutdown of all outputs. As-
suming that the outputs are not switched off elsewhere, then after the reset,
they are switched on again.

System overload alarm
threshold time [ms]
Time delay before an alarm is issued after a system overload was detected. Unsigned16
Main power outage
alarm threshold time
[ms]
Time delay before an alarm is issued after failure of the power supply voltage
(power supply changes into the BUFFER MODE).

Data
Description
Data type
Utarget [10mV]
Currently set setpoint of the output voltage.
Unsigned16
Ilimit [mA] Response threshold of the output current for an output. When this is exceeded,
the output current is interpreted as having an overload condition and is shut
down with a time delay - or limited.
The response threshold is set in the following steps depending on the maxi-
mum output current:
• Output current 20 A: 20 mA (0.02 A)
• Output current 40 A: 40 mA (0.04 A)
Values that deviate from this grid are rounded off to the next permissible value
in the device.
Unsigned16
Ithreshold (0-100%) Prewarning threshold of the configured response threshold for the output cur-
rent in %. An alarm is initiated when the actual output current exceeds this
value. Operation is continued without any restrictions. Prewarning is deactivat-
ed by entering "0 %".
Unsigned8
OutputEnable (0/255) Switch on output Switches the output on or off. A possible automatic shutdown
due to overload or power failure is not taken into account.
Unsigned8
Reset Resets the output: Resets the automatic overload shutdown of an output. As-
suming that the output is not switched off elsewhere, then after the reset, it is
switched on again.
