2.
After the BACnet routers are discovered, you should see a BACnet router that matches the DNET
configured for the Intelli-Hood system. Select that BACnet router on your Operator Workstation.
3.
After selecting the Intelli-Hood BACnet router, perform Device discovery again. You should now
see the virtual Device Objects.
Another common cause is if the Intelli-Hood’s DNET is configured for the same DNET as a
different BACnet router or BBMD on the network. To diagnose this problem:
1.
Validate the DNET for the Intelli-Hood system is configured correctly. See the section “BACnet
Setup and Configuration” for details on how to validate the DNET is configured correctly.
2.
If the DNET is configured as intended, verify that there isn’t another BACnet router or BBMD that
is incorrectly configured for the same DNET. To do so, unplug the Intelli-Hood system from the
network and then attempt to discover the BACnet networks (“Network Discovery” or “BACnet
Discovery” as described above). If you discover a device that is setup with the Intelli-Hood’s
DNET, then determine whether to change the Intelli-Hood’s DNET or the other device’s DNET.
It is also possible that all Exhaust Fans, Auxiliary Airflows and Hood Controllers are
configured with incorrect Device Instance Numbers or are configured to not be visible
through the BACnet interface. See the section “BACnet Setup and Configuration” and
validate the Exhaust Fans, Auxiliary Airflows and Hood Controllers have correct BACnet
configuration.
Cannot set the Intelli-Hood system time
Problem: Through the Operator Workstation, you are attempting to set the Intelli-Hood’s
system time using either Time Synchronization or UTC Time Synchronization. The Intelli-
Hood system is responding but the Intelli-Hood system’s time is not changing.
Diagnosis: There was an issue with Time Synchronization and UTC Time Synchronization
in system firmware FW2015.09.16 and earlier. If this is the case, then contact Melink
about obtaining a firmware upgrade for your Intelli-Hood system.
