Removing from DIN rail WIRING DIAGRAMS KNX bus ATTENTION! Installation and connection of the device to the mains must only be carried out by qualified personnel! There is a risk of electric shock! Be sure to turn off the power before installing or removing the device! Even when the device is turned off, the output...
Number and duration of overloads are stored. The same applies for the number of short circuits, device startups, KNX bus resets and for the duration of load detachments. The total operating time of the device and its operating time since last device startup are stored, too. Threshold values can be set for the bus voltage (only in the additional alarms), total current, telegram traffic and internal device temperature.
Number of short circuits and duration of load detachment are available details. The same applies for the number of KNX bus resets and of device startups, and for operating times. Additional alarms also provide the number of a value being in the threshold range and the duration of such event.
2.3 PARAMETER STRUCTURE FOR MEASUREMENT SOURCES On enabling a measurement source in the ETS tab «Measurements», the following parameter structure is available (exception: counters). An actual value can be sent over the bus a er a certain value change («Sending difference») or a er a pre-set time period has elapsed («Cyclic sending»). A value reaching the excess threshold range can be used to send telegrams containing «1»...
2.4.2 INDIVIDUAL ADDRESS ASSIGNMENT To configure the device an interface connection (IP, USB) to the KNX bus system is required. The device is supplied with the Individual Address 12.12.255. The KNX product database entry (available for ETS4 and higher) can be downloaded from the website and from the KNX Online Catalog.
During a bus reset, the device disconnects the entire bus line from the supplying output and induces a short circuit for 20 seconds. LED 6 (KNX Bus Reset) lights up red and goes off a er the reset process is accomplished.
3 ETS DATABASE PARAMETERS All screen shots are related to the PS-S.640.30.1 database file R1-1b in ETS5. Figure 2. Parameter tabs In the «General» tab the heartbeat period, the remote reset type (reset with «0» or with «1») and the delay of messages a er startup can be configured.
«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» a er a KNX bus reset, a device startup and a short circuit. A er returning to normal working condition during the time delay no telegrams are sent.
3.2 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»...

3.3 MAXIMUM TRACKING With setting the «Tracking period» a certain period of time is tracked in order to find the maximum observed value contained. A er 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». Figure 5.
3.4 TELEGRAM TRAFFIC The «Telegram traffic» measurement source is similar to the measurement sources in the ETS tab «Measurements». The excess threshold range of the «Telegram traffic» is located only above its working range. Figure 6. Telegram traffic tab parameters Setting ETS Parameter Comment...

3.5 ERROR COUNTERS The «Error Counters» tab contains the menus «Overload number counter», «Overload time counter», «Short circuits number counter» and «Load detached time counter». Activation of the parameters also activates the related communication objects. Info telegrams containing actual values can be sent regularly or according to a pre-set value difference.

3.6 OPERATIONAL COUNTERS The «Operational counters» tab contains the menus «KNX bus reset number counter», «Device startup number counter», «Total operating time» and «Operating time since last device startup». Activation of the parameters also activates the related communication objects. Info telegrams containing the actual number counter value can be sent regularly.

3.7 ALARM 1,2,3,4 A er enabling the alarm function the measurement source can be chosen. With the menu item «Alarmtype» the threshold range can be set. The alarm activation/deactivation can also be used to switch other devices. With the additional alarms 1-4, durations and numbers of threshold events can be sent on the bus.
