4 3 2 HV DTemp-P central unit connectors
The CAN sockets located in the lower half of the front panel (Fig. 3-2,
➃
) are used both for
transmitting CAN signals and for power supply. The interface cable connects the module
with the data acquisition system (computer) and the power supply.
NOTE!
i
Take special care when connecting third-party devices to a measurement
bus with HV DTemp measurement systems.
Ensure that the configuration settings are compatible with all devices
(same CAN bit rate, different CAN identifiers).
Make sure that this work is only carried out by qualified and trained
personnel.
NOTE!
i
The CAN sockets for CAN signals and power supply are connected in parallel
and have identical pin assignments. The signal applied to a specific pin is
therefore always available at both sockets.
Make sure that this work is only carried out by qualified and trained
personnel.
The controllers and the sensors connected to them are connected to the HV DTemp-P central
unit using the 8-pin multi-connector sockets (Fig. 3-2,
➁
).
If required, the HV DTemp-P central unit can be connected to ground using the M6 threaded
hole in the top side of the front bracket (Fig. 3-2,
➀
) .
4 3 2 1 CAN sockets
The CAN sockets are connected in parallel so that the signals are always present at both
sockets. Both sockets can be used for either
CAN IN
or
CAN OUT
. This enables simple cabling
with only one cable between two modules. At the end of the measurement chain, a CAN
termination resistor is plugged into the open CAN socket.
CSM uses LEMO 0B sockets as standard for the CAN sockets. To connect a cable to this
socket, the following plug with plug insert is required:
