Operating the device
10.3 Settings for the internal analog interface
+
Analog int
Via this menu you can access settings for the built-in, i.e. internal
analog interface:
Analog voltage
Default:
0...10 V
= 0...10 V
Selects 0...10 V for 0...100% set/actual values.
= 0...5 V
Selects 0...5 V for 0...100% set/actual values.
The reference voltage at pin VREF is automatically adjusted to
the above selection and will be either 5 V or 10 V.
REMOTE /5
Default:
LOW
= LOW
Unit switches to analog remote control, if the
pin is pulled to LOW (ground).
= HIGH
Unit switches to analog remote control, if the
in is pulled to HIGH or left open.
Attention!
The pin is tied to HIGH level by default. It means, if setting
HIGH
is selected and the pin is left open, the device will
permanently be in analog remote control, unless
local
is activated.
REM-SB /13
Default:
LOW
= LOW
Unit switches the DC output off, if the pin is
tied to LOW (ground).
= HIGH
Unit switches the DC output on again, if the
pin is tied to HIGH.
Attention!
The pin is tied to HIGH level by default. It means, if set-
ting
HIGH
is selected and the pin is left open, the DC
output would be permanently switched off, unless
local
is activated.
OVP /14
Default:
LOW
OT /6
Default:
LOW
CV /15
Default:
LOW
= { LOW | HIGH}
Defines, if the digital outputs will report
their dedicated status with either LOW
or HIGH level.
10.4 Example applications
Attention!
Never connect any ground of the analog interface to
minus (negative) or plus (positive) output of the device!
This will eliminate the galvanic isolation and possibly put
dangerous potential to the analog interface and thus also
to the control application (eg. a PLC), especially when
operating the DC output on transformerless inverters.

Note
A digital output of a PLC or any other controlling application
may not be able to pull inputs like
REMOTE
or
REM-SB
to
LOW. Refer to the technical specifications of the particular
hardware for details.
