fault has been removed.
10.3.7 Software Version and Revision indication
For identification purposes and to assist in queries, the Software version and revision, and
the controller serial number are indicated in the calibrator Test Menu.
10.3.8 Dashboard Displays
Sevcon offers both a standard display and a full feature display for connection to the SC2000.
See section 11 for more information.
10.3.9 Setup Menu
A setup menu has been added to the Calibrator that allows various features to be enabled
and disabled. See section 7 for more information.
Note. Once a change has been made to the setup menu, the Key switch must be recycled for
the change to be operational.
10.3.10 Node Number
Using the setup menu a facility exists to adjust the Node Number between 0 and 15, and is
used to determine which Controller, on a multi controller CAN system, is the master and
communicates with the display. On single Controller systems, including integrated
Traction+Pump systems the number will always be set to 0. However on systems where there
is more than one controller i.e. a standalone Traction controller and a standalone Pump
controller, one of these should be set 0 and the other to 1. On Multi controller systems
number the master 0 and the others 1,2,3...etc.
10.3.11 Multi Languages
Non-English languages can be specified for displaying on the Calibrator. Languages can be
presently specified as either English, German, Spanish, Italian or French.
