5.1.2.3.6 Output SICAM Q80 7KG8080
Pre-defined functions can be assigned to the digital outputs. By this means, for example, a variety of measurement
states can be signalled by external display elements.
The digital outputs are designed as relay contacts: If a bit's value is 1, the switch is closed. The connected voltage
must be supplied from outside. There is no internal connectable voltage (TTL etc.)
Clicking in the function column of a binary output opens a list of available functions:
Digital outputs; load default settings by button "Set Default"
LED – shines green when the relay is closed.

For cutoff values, values can either be defined or parameters of the selected standard can be used.
Function
Description
System fault / device active
Only at DO1: The closed relay contact (LED=green) indicates that the device is
measuring. If the relay fails during measurement (LED=red), then there is either an
error in calculation of the data, or the measurement has been concluded correctly.
Voltage dip
The relay closes when the RMS voltage value falls below the
.
Low free storage
The relay closes when the free data storage falls below a cutoff limit. The cutoff
limit is specified in MBytes.
Unbalance
The relay closes when the asymmetry exceeds a
.
No synchronization signal
The relay closes when the synchronization signal is no longer available.
RMS trigger U
The relay closes when the RMS voltage value deviates according to the settings in
the
(No. 5).
RMS trigger I
The relay closes when the RMS voltage value deviates according to the settings in
the
(No. 8).
Frequency trigger
The relay closes if the frequency deviates according to the settings in the
(No. 9).
THD U
The relay closes when defined for THD occurs.
Harmonics U
defined for the harmonics occurs.
Active Overall system
defined for the overall system's power occurs.
Reactive Overall system
Apparent Overall system
Power factor Overall system
defined for the overall system power factor
occurs.
Active line
defined for a line power value occurs.
Reactive line
Apparent line
Power factor line
defined for a power-power factor occurs.
