4.1.3 External CAN Bus
The CANbus interface will be connected by the RJ-45 connectors CAN HV (IN/OUT) on the front panel. 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 4.1.6 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 manual of
the module) 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.

INFORMATION
Please use a CAN-Bus termination.
4.1.4 SAFETY LOOP 1
IS (Internal SL current) 2-pin Lemo socket one side connected to + 24 V with ca. 10 Ω / 3 W, other side connected to module
station. If the module safety loop of the built-in multichannel module with option SL is active then an output voltage in any
channel of it is only present if this safety loop is closed!
4.1.5 SAFETY LOOP 2
INHIBIT 2-pin Lemo socket for external INHIBIT signal to shut down the integrated HV module with ramp. LOW level on the right
pins or connecting to the left pins: INHIBIT is active HIGH level or open: Output according setting
