Settings for the analog interface
+
Analog interface +
Via this menu you can access settings for the built-in, i.e.
internal analog interface:
Analog in./out.
Selects the voltage range for the analog set
values inputs and actual value outputs
Digital inputs
Defines if the digital control inputs will act
at LOW or HIGH level.
Digital outputs
Defines if the digital status outputs will act
at LOW or HIGH level.
Analog voltage
= 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
= LOW
Unit switches to analog remote control, if the
pin is pulled to LOW (ground).
= HIGH
Unit switches to analog remote control, if the
pin is pulled to HIGH or left open.
REM-SB /13
= LOW
Unit switches the DC output off, if the pin is
pulled to LOW (ground).
= HIGH
Unit switches the DC output on again, if the pin
is pulled to HIGH or left open.
Attention!
Both pins, REMOTE and REM-SB are internally tied to
HIGH level by default. It means, if setting
and the pin is left open, the device will permanently stay
in analog remote control (pin REMOTE) and/or have the
DC output switched off (pin REM-SB)!
OVP /14
OT /6
CV /15
= { LOW | HIGH}
Defines, if the digital outputs will report
their dedicated status with either LOW
or HIGH level.

Example applications
Attention!
Never connect grounds of the analog interface to minus
(negative) output of an external control application (PLC,
for example), if that control application is otherwise
connected to the negative power supply output (ground
loop). Load current may flow over the control cables and
damage the device!
