In Operation
In order to regularly monitor the presence of the Switch Actuator on the ABB i-bus
monitoring telegram can be sent cyclically on the bus.
This communication object is always enabled.
Telegram value: 1= system operational
0 = send inactive
1 Safety Priority 1
This communication object is enabled if in parameter window General the
parameter Function Safety Priority 1 is selected with the option enabled by object value "0" or
enabled by object value "1".
The Switch Actuator can receive a 1 bit telegram via this communication object, which another
KNX device, e.g. diagnostics module or wind sensor, sends cyclically. On receipt of the
telegram, the communication capability of the bus or the sensor (signalling device) can be
monitored. If the Switch Actuator does not receive a telegram (value can be programmed) on
the communication object Safety Priority 1, a fault is assumed, and a response programmed in
parameter window A: Safety is implemented. The output of the Switch Actuator goes into a
safety state and does not process any telegrams. Only after the communication object Safety
Priority 1 again receives a 1 or 0 (depending on the parameterization) will incoming telegrams
be processed again and the contact setting changed.
The control period can be adjusted in the parameter Control period in seconds.
The safety priority 1 is also triggered if a telegram with the programmable trigger value is
received.
