EtherCAT Connection: The VDM300 provides optional, incremental
EtherCAT communication via dual RJ45 jacks. An Ethernet Cat 5 type
cable needs to be connected between the tool interface and the
VDM300.This connection allows the user to send commands and set
points and receive flow and alarm signals from the VDM300. It also
enables firmware upgrades. Please note that the EtherCAT communication
replicates all of the analog I/O functions with the exception of the DC
power supply. The VDM300 always requires the Analog Connection for the
DC power supply. Reference Supplemental Manual for Brooks Instrument
EtherCAT for VDM300 Series (X-DPT-EtherCAT-VDM300-eng) for specific
EtherCAT assignments.
Power Entry Module Connection and Configuration: The connection to
the power entry module is a standard IEC C-14 connector. This is where
AC power for the VDM300 internal tank heaters is connected. This AC
power is only for the tank heaters. lt does not supply power to any of the
internal electronics in the VDM300. Without this power, however, the
VDM300 will not operate properly since there will be no power available to
heat the Dl water in the titanium tank.
Diagnostic Port Connection: There is one more optional electrical
connection for using the optional USB communication connection. This
connection is not used for normal VDM300 operation. This connection will
be explained in Section 2-7 Diagnostic Port Communication.
Assuming that the user connections meet the above mentioned
requirements, the following steps can be taken to complete the installation
of the VDM300:
1. Make certain that the VDM300 is properly mounted and that all
mechanical connections have been properly made. Refer to Sections 2-4
and 2-5 earlier in this manual.
2. Make certain that the ON/OFF switch in the power entry module is in the
"Off" or "∅" position.
3. Connect the tool interface DB-15 receptacle to the lnput/Output DB-15
plug on the VDM300. lt is recommended that this connection be secured to
the jack screws on either side of the DB-15 plug on the VDM300. Note that
if the DC power supplied by the user is on, the VDM300 electronics will
power up at this point. lt is recommended that Pin 4 and Pin 14 of the DB-15
not be grounded at this point to keep the VDM300 in the idle state.
4. Attach the supplied ferrite core to the control cable right below the DB-15
connector.
5. Connect the AC power to the power entry module.
6. Switch the ON/OFF switch on the power entry module to the "On" or "1"
position.
The installation process for normal VDM300 operation is now complete.
