ERS COMPACT
1.9.10
Analog interface (standard models)
This 15 pole D-sub socket on the rear side of the device is provided for remote
control of the device via analog or digital signals.
If remote control is in operation this analog interface can only be used alternately
to the digital interface. 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 set
-
tings menu of the device between 0-5 V and 0-10 V, in each case for 0-100%.
1.9.11
“Share BUS” connector
The two BNC sockets (50 Ω type) labeled “Share BUS” form a digital, passed-
through Share bus. This bus is bidirectional and connects the bus master unit
via “Share BUS Output” to the next slave unit (“Share BUS Input”) etc., for
use in parallel operation (master-slave). BNC cables of suitable length can be
obtained from us or electronics stores.
Share bus operation requires to connect only identical device models. Follow-
ing power supply and electronic load series are compatible on this Share bus:
• ERSC 10000
•
ERSC 10000 Slave
•
ERSCE 10000
• ELR 10000
• PSI 10000
1.9.12
“Sense” connector (remote sensing)
In order to compensate for voltage drops along the DC cables to the load or
external source, the Sense input (2 plugs included in delivery, one each for
positive and negative pole) can be connected to the load resp. external source.
The maximum possible compensation is given in the technical specifications.
In a master-slave system it’s intended to wire remote sensing
only to the master which would then forward the compensa-
tion to the slaves via Share BUS.
1.9.13 Master-Slave bus
There is a further set of connectors on the rear side of the device, comprising
two RJ45 sockets, which enables multiple compatible devices to be connected
via a digital bus (RS485) in order to create a master-slave system. Connection
is made using standard CAT5 cables.
It’s recommended to keep the connections as short as possible and to terminate
the bus if required. The termination is done via digital switches and activated
in the device setup menu in group “Master-Slave”.
