Using the power supply
9.3 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 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
Default:
0...10V
= 0...10V
Selects 0...10V for 0...100% set/actual values.
= 0...5V
Selects 0...5V for 0...100% set/actual values.
The reference voltage at pin VREF is automatically adjusted to
the above selection and will be either 5V or 10V.
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
pin is pulled to HIGH or left open.
REM-SB /13
Default:
LOW
= 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
HIGH
is selected
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
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.
9.4 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!
