4-3. Wiring Earth Grounding
In the real fields, there might have a lot of automatic device, such as AC
motors, electric welding machine, power generator; those devices will
generate electromagnetic and disturb communications. To prevent those
noises, the switch should be well earthed. In the figure-shows how to
make connection.
4-4. Enabled the Event Alarm Function
This session introduces how to configure and enable the event alarm to
alert maintenance engineer once system event occurred. Both of JetNet
3008 and JetNet 3008f equipped with one dry relay output for port link fails
or power fails. The feature is controlled by digital control circuits and effect
immediately without system reset when DIP SWITCH changed.
On the bottom side of JetNet 3008 and JetNet 3008f, there is one 9-Pin
DIP SWITCH for alarm control. By inserting the port and power wiring,
setting the DIP SWITCH of the intended Alarm to “ON”, the relay output
will form a short circuit if alarm occurred.
