The setup menu

The setup menu can activated anytime by the selector Le-
vel(3), except during remote control mode (by interface card)
or external mode (analogue interface). While the load is in
setup, no normal load operation is possible.
The display shows a certain number of parameters, depen-
ding on which interface card is installed. The parameters are
selected by Selection(5) and changed with 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 parameters which
are selected by Selection(5). The number of parameters
varies according to the equipped interface card. The following
overview lists the possible parameter and its 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).
Device node
Possible settings: 1...30
Default setting: 1
Belongs to: Device
Explanation: defines the device node (or address) of the
device in order to distinct between mutliple devices in a net-
work and to address it correctly. 0 addresses are available
which means that up to 0 devices can be controlled from
one PC. Every address must only be given once in a system
of connected devices.
Keep set values
Possible settings: yes, no
Default setting: no, since firmware 3.01:
Belongs to: Device
Explanation: yes defines, that the set values which are
adjusted by the user are kept when switching the regulation
mode (also see „6.6 Preselecting the regulation mode"), while
no defines that the set values are always reset to default
values when switching.

CAN Baud rate
Possible settings: 10kBd, 20KBd, 50kBd, 100kBd, 125kBd,
Default setting:
Belongs to: CAN interface card IF-C1
Explanation: determines the baudrate (transmission speed)
of the CAN bus. 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 Relocatable ID
Possible settings:
Default setting:
Belongs to: CAN interface card IF-C1
Explanation: this determines the (relocatable) address seg-
ment, in which the device node of the CAN is located. For
further information refer to basic CAN topology datasheets.
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, 2 x 0 possible device nodes available
when using CAN.
CAN Bus terminate
Possible settings: yes,
Default setting:
Belongs to: CAN interface card IF-C1
Explanation: defines, if the bus termination resistor on the
CAN interface card is active or not. This is only required if
the CAN card is in that particular device which is located
at the end of a CAN bus. By setting this parameter to
the resistor is activated,
want to use this feature and instead want to install a custom
resistor for bus termination, make sure that this setting is
set to no.
RS232 Baud rate
Possible settings:
Default setting:
Belongs to: RS22 interface card IF-R1
Explanation: determines the baudrate (transmission speed)
of the serial data transmission when using the serial RS22
yes interface card IF-R1. Make sure, that the other end of the
serial connection operates at the same baudrate.
