ETS Database Parameters
Intelligent Power Supply KNX PS640-IP 2U
• Version: 21.09.2021 • Technical changes and errors excepted.
•
Using the "Sending difference" function with the "Output voltage" is possible
only within the "Alarm 1,2,3,4" tabs like described in chapter 3.7.
•
The "Output voltage" value is valid only if most of the load is on the KNX bus
output
•
If the "Output current" value is < 10 mA, for calculations, the input voltage is
assumed to be at 230 V AC
6.3. Maximum Tracking
With setting the "Tracking period" a certain period of time is tracked in order to find the
maximum observed value contained. After each expired period this value can be sent
over the bus. The maximum tracking function is available for the measurement
sources "Output current" and "Device Temperature".
Device temperature
Device temperature [°C]
disable • enable
Enable/disable group associations, measurement and following settings.
Sending difference
2...10 °C
Difference between actual and last sent value which triggers the sending.
Cyclic sending

• send value 1
• set value to 0
• set value to 1
Select action on entering the threshold range.
Behaviour on alarm deactivation
• disabled
• send value 0
• send value 1
• set value to 0
• set value to 1
Select action on leaving the threshold (+hysteresis) range.
Tracking period [s]
10…32,000 [s]; 1,800
Determination of the time period for maximum value tracking.
Maximum value of Output current
Output current maximum [mA]
