Monitoring voltage and current
The analog monitoring outputs put out 0...5V or
0...10V, depending on the voltage range selection
in the setup, which each corresponding to 0...100%
of the nominal values.
Reference is analog ground (AGND).
5.2.2 Application examples
Note: recommended cross section when wiring the
clamp pins of the analog interface: 0,1mm² (AWG26)
to 0,5mm² (AWG20).
Remotely switching DC output on / off
This input can be used to switch
off
the DC power
output even without activated remote control, except
the control location was set to
local
(also see sec-
tion 3.8). In this situation the pin acts as a disabler,
preventing the DC output from being switched on
again, which would have to be done with ON/OFF
button on the panel. If the input is configured to
LOW
(see section 4.6.2), then the power output can
only be switched on again by opening the contact
or releasing the switch.
During normal remote control via analog interface,
this pin solely defines the state of the DC output.
