Device Configuration; The Setup Menu - Elektro-Automatik EL 9000 A Bedienungsanleitung

Settings
7. Device configuration
7.1 The setup menu
The setup menu can only be activated by the selector
Level(3), except during remote control. While the load is
in setup, no normal load operation is possible.
The display shows a certain number of parameters,
depending on which interface card is installed. The para-
meters are selected by knob Selection(5) and changed
with knob Setting(6). Two small triangles on the right
side of the display indicate that multiple parameters are
available. The display furthermore shows the type string
of the installed card in the first line, for example IF-U1, if
one is equipped:
Figure 14
The second line subsequently shows all available para-
meters which are selected by Selection(5). The number
of parameters varies depending if an interface card is
equipped or not.
There are following settings:
Trigger mode
Possible settings: internal, external
Default setting: internal
Belongs to: Device
Explanation: defines, if the trigger signal for the Level A/B
operation, which effects the change between A and B, is
automatically generated by the device (internal) or if it's
put in by the trigger input (external).
Keep set values
Possible settings: yes, no
Default setting: no
Belongs to: Device
Explanation: yes defines, that the set values which are
adjusted by the user are kept when switching the regu-
lation mode (also see „6.6. Preselecting the regulation
mode"), while no defines, that the set values are always
reset to default values when switching.
Device node
Possible settings: 1...30
Default setting: 1
Belongs to: Interface cards
Explanation: defines the device node (or address) of the
device in order to distinct between multiple devices in
a network and to address it correctly. Up to 30 devices
can be controlled from one PC. Within a bus system like
CAN or GPIB, every address must only be given once.

EL 9000 A Series
CAN Baud rate
Possible settings: 10kBd, 20KBd, 50kBd, 100kBd,
125kBd, 250kBd, 500kBd,
Default setting: 100kBd
Belongs to: CAN interface card IF-C1
Explanation: determines the transmission speed of the
CAN bus messages. If you connect the CAN card to an
existing network, you got to set the same baudrate here
as the bus is using, becaus any device in a bus has to
use the same bus speed.
CAN ID System (available since firmware 5.01)
Possible settings: normal, Vector
Default setting: normal
Belongs to: CAN interface card IF-C1
Explanation: with this, the user selects whether to use
the normal CAN ID system with 2 IDs per unit or the new
Vector compatible CAN ID system with 3 IDs per unit. With
setting normal, the two IDs per unit build from the
node and the Relocatable ID
manual for calculation scheme). With setting Vector, the
device will be assigned three CAN IDs, starting from the
base ID (see below), which is adjustable in steps of four
withing the whole ID range (11 bits, 0...2047). An addi-
tional ID is assigned as broadcast ID, which is seperate
from the three base IDs.
Note: depending on the setting being
subsequent parameters will change.
CAN Relocatable ID
Possible settings: 0...31
Default setting: 0
Belongs to: CAN interface card IF-C1
Explanation: this determines the relocatable address
segment in which the CAN IDs of the device are located.
For further information refer to basic CAN topology datas-
heets. Example: if the electronic load has to be assigned
to address 5 by certain reasons and this would collide
with another bus member with the same address, you can
move the address to another segment by defining the RID
(short for relocatable ID), so that no collision can occur.
Hence there are, theoretically, 32 x 30 possible device
nodes (with two IDs each) available when using CAN.
