Handling the device
Note: analog remote control is only possible with
voltage profile 1 selected. Otherwise, the device will
signalise alarm
EXT
.
Digital inputs
(default:
LOW
)
The digital inputs can be selected to be low-active
or high-active.
If set to
LOW
the input will execute its defined func-
tion at low input level. See the technical specifica-
tions table of the analog interface for details.
If set to
HIGH
, the input will react to input level high.
Digital outputs
(default:
LOW
)
The digital outputs can be selected to be low-active
or high-active.
The outputs will signalise their defined function
with the selected output level, i.e. by switching to
GND at
LOW
or to high potential at
HIGH
. See the
technical specifications table of the analog interface
for details.
Display illumination
Backlight
(default:
Delay
60s
)
If
Backlight = Delay 60s
is set, the backlight is gen-
erally off and will be switched on for 60s after every
push of a button. For permanent backlight select
option
Backlight = ON
.
4.6.2 Menu item „Analogue interface“
This configures the built-in analog interface. The
analog inputs and outputs can work with the com-
mon 0...5V and 0...10V control voltage ranges. In the
range 0...5V the resolution and accuracy are halved.
Analogue in./out.
(default:
0...10V
)
If
Analogue voltage = 0...10V
is selected, the analog
inputs and outputs will accept 0...10V for 0...100%
nominal values. With 0...10V range selected, volt-
ages >10V are clipped to 100%.
The selection
Analogue voltage = 0...5V
will work
accordingly. With 0...5V range selected, voltages
>5V are clipped to 100%.
Note: analog remote control is only possible with
voltage profile 1 selected. Otherwise, an alarm
EXT
is generated.
