MANUAL CONTROL
HeatingBOX
allows controlling the outputs through the pushbuttons on the top of the device.
Each output has its associated pushbutton.
Manual operation can be done in two different ways, named as
Test On Mode
(for testing
purposes during the configuration of the device) and
Test Off Mode
(for a normal use, anytime).
Whether both, only one or none of these modes are available needs to be parameterised in ETS.
Moreover, it is possible to enable a specific binary object for locking and unlocking the manual
control in runtime.
Note
:
The
Test Off mode
will be active (unless it has been disabled by parameter)
after a download or a reset with no need of a specific activation
– the
pushbuttons will respond to user presses from the start.
On the contrary, switching to the
Test On mode
(unless disabled by
parameter) needs to be done by long-pressing the Prog./Test button (for at
least three seconds), until the LED is no longer red and turns yellow. From that
moment, once the button is released, the LED light will remain green to confirm
that the device has switched from the Test Off mode to the Test On mode. After
that, an additional press will turn the LED yellow and then off, once the button
is released. This way, the device leaves the Test On mode. Note that it will also
leave this mode if a bus power failure takes place.
The manual control of the outputs is intended to perform on/off switches,
independently of the method of control configured (one-bit or one-byte). In
other words, it does allow testing the opening and closing of the valves, but
intermediate positioning is not possible.
Test Off Mode
Under the Test Off Mode, the outputs can be controlled through both their communication objects
and the actual pushbuttons located on the top of the device. Also, during this manual control
mode, the control commands received by the bus will continue to be analysed and executed.
