• Remote control has not been activated
In this mode of operation pin REM-SB can serve as lock, preventing the DC input from being switched on by any means. This
results in following possible situations:

The DC input isn’t locked. It can be switched on by pushbutton “On/Off”
(front panel) or via command from digital interface.

The DC input is locked. It can’t be switched on by pushbutton “On/Off”
(front panel) or via command from digital interface. When trying to switch
on, a pop-up in the display resp. an error message will be generated.
LOW

Normal
In case the DC input is already switched on, toggling the pin will switch the DC input off, similar to what it does in analog
remote control:

The DC input will be switched off and locked. Later it can be switched on
again by toggling the pin. During lock, pushbutton or digital command
can delete the request to switch on by pin.

b) Remote control of current and power
Requires remote control to be activated (pin REMOTE = LOW)
The set values PSEL and CSEL are generated from, for example,
the reference voltage VREF, using potentiometers for each. Hence
the power supply can selectively work in current limiting or power
limiting mode. According to the specication of max. 5 mA load for
the VREF output, potentiometers of at least 10 kΩ must be used.
The voltage set value VSEL is directly connected to VREF and will
thus be permanently 100%. This also means that the device can
only work in source mode.
If the control voltage is fed in from an external source it’s neces-
sary to consider the input voltage ranges for set values (0...5V oder
0...10 V).
When using the voltage range 0...5 V the effec-
tive resolution of set values and actual values
halves.

c) Reading actual values
The AI provides the DC input values as current and voltage monitor. These can be read using
a standard multimeter or similar.
