ETS Database Parameters
The default settings of the parameter are labelled by an underscore.
6.1. General
The "General" tab contains the parameters related to the presence message sending
and the KNX bus reset that can be initialized by communication object no.16. With use
of the communication object no.37 "Heartbeat" the device periodically sends out a
telegram with "1". With use of the communication object no.36 "Power supply is on"
the device sends out a telegram with "1" after a KNX bus reset, a device startup and a
short circuit. After returning to normal working condition during the time delay no
telegrams are sent. Then, the "Power supply is on" telegram is the first one that is sent.
6.2. Measurements
The "Measurements" tab contains the menus "Output voltage", "Output current" and
"Device temperature". The excess threshold range of the "Output voltage" is fixed and
located outside the working range (28-31V). For example, with no "Output voltage"
hysteresis the "Behaviour on alarm deactivation" function is executed on just entering
the working range. The "Output current" and the "Device temperature" excess
threshold ranges both are located above the working range.
Heartbeat period [s]
10…32,000 s; 60 s
Info telegram (with "1") is regularly sent after this time period.
