3 Operation and maintenance
The connection with mains is made through an inlet connector on the rear side of the device. The mains switch and the fuse is
also located at this place.
3.1 Front panel
The CANbus interface will be connected by the DSUB-9 connectors CAN HV (IN/OUT) on the front panel. In case of using more
than one crate the final CANbus connector has to be terminated with 120 Ohm.
In case of using more than one crate the different module address for each module on the CANbus has to be configured with
help of the bank select switch (see Chapter 3.2 Bank select switch) on the front panel.
After Switch
ON
and system initialization of CANbus the connected Multi Channel iseg HV-modules can work under remote
control via PC.
If using Multi Channel iseg HV-modules with internal supplied safety loop, bridging the two pins of the SL connector on the front
of the crate will be connect the module SL to the current source in the crate. If the module safety loop is active (see the
) removing the bridge during operation (opening the loop) then the output voltages on all channels are shut off
without ramp and the corresponding bit in the ‘Status module’ will be cancelled. After the loop will be closed again the channels
must be switched
ON
and a new set voltage must be given before it is able to offer an output voltage.

Description
RESET
It is able to send a module RESET with the built-in module
RESET push bottom.
ON
On LED
BANK SELECT
With the BANK-SELECT-switch select the used bank with
fixed module address.
SL
With help of the SL connector it is able to provide the
internal safety loop of built-in custom specific
multichannel HV modules with a current up to 300 mA.
CAN
The external CAN-Bus (CAN-HV) to control the iseg HV
module is connected through DSUB-9 connectors on the
front panel.
