EL 3000 B Series
1.9.8 Analog interface (optional)
On the rear side of the device there is a slot to install one out of three types of
optionallyavailable,user-retrottableinterfacecards.Alsoseesection1.9.4. One
of the types features an analog 15 pole D-Sub type connector, plus an USB port.
This 15 pole socket is provided for remote control of the device via analog and-
digital switch signals.
When requesting remote control via the analog port it has no priority over the
digital interface and can, therefore, only be used alternatively to these. However,
monitoring is always available.
The input voltage range of the set values and the output voltage range of the
monitor values, as well as reference voltage level can be switched in the settings
menu of the device between 0-5 V and 0-10 V, in each case for 0-100%.
1.9.9 “Sense” connector (remote sensing)
In order to compensate for voltage drops along the DC cables, the Sense input
(between the DC input terminals) can be connected to the source. The device will
automaticallydetectwhenthesenseinputiswired(Sense+)andcompensatethe
input voltage accordingly.
