10.5.5 Measuring actual values
Measuring the monitor outputs of the actual values is inde-
pendant from remote control. Since there is no power monitor
output, only voltage and current monitor can be measured. The
pins VMON and CMON represent the actual DC output values
with either 0...10V or 0...5V for 0...100%.
By using an external analogue multiplicator, the power monitor
could be calculated.
10.5.6 Notications
The analogue interface features further outputs like OVP or CV
to notify the user of alarms or conditions (see table in „10.4.
Pin specications“).
These outputs are internally pulled to a voltage source via a high
resistor and can not drive a LED or lamp. They‘re intended for
current intake by switching an external relay or similar, which
can drive LED, lamps or other indicators.
Alternatively, these outputs can be connected to inputs of logic
ICs.

10.5.3 Activate remote control
Switching to remote control is required as soon as the device
is going to be controlled with external set values.
Remote control is active as long as pin REMOTE is given the
corresponding level and remote control is not interrupted by
LOCAL mode.
Remote control active: REMOTE = LOW | HIGH
Remote control inactive: REMOTE = HIGH | LOW
With this series, the level to switch the device to remote control
depends on the setting LOW or HIGH, given for this pin in the
device setup.
Attention! This pin is internally pulled up to HIGH. When selec-
ting HIGH in the setup menu for this pin, the function „remote“
would be permanent and would require to pull the pin to LOW
rst, in order to be able to manually or digitally control the device.
Note: LOCAL mode interrupt any remote control. As long as
LOCAL is active, values and condition can only be set manually
on the device. As soon as LOCAL is deactivated, the remote
control becomes active again, if pin REMOTE still gives.
Attention! When switching to remote control while the DC output
is on, there might be a higher, dangerous output voltage on
the output, depending on the given set values on the analogue
interface!
10.5.4 Remote control of set values
Note: During remote control, it is always required to give all set
values U, I and P. If the power set value is not given, the device
won‘t put out voltage.
The inputs VSEL (voltage U), CSEL (current I) and PSEL (power
P, where adjustable) have to be given with external, analogue
voltages. For 0...100% value on the DC output it requires either
0...5V or 0...10V input voltage on these inputs.
