Monitoring voltage and current
Analogue outputs (AO)
The analogue monitoring outputs VMON and CMON
put out 0...5V or 0...10V for 0...100% nominal value,
depending on the voltage range selection in the setup.
Reference is analogue ground (AGND).
5.2.2 Example applications
Note: recommended cross section when wiring
the clamp pins of the analogue interface: 0,1mm²
(AWG26) to 0,5mm² (AWG20).
Remotely switching output on / off
Digital input (DI)
This input can be used to switch off the power output
even without activated remote control, except the
control location was set to
local
(also see section 3.8).
If the input is configured to
LOW
(see section 4.5.2),
then the power output can only be switched on again
by opening the contact or releasing the switch.
The contact/switch on pin 8 overrides button „ON“.
