OPERATION / SET UP OF EA2400HBM / EQ2400HBM
1- Strap tester module to wrist.
2- Plug test leads into test jacks.
3- Place ON/OFF switch in the “ON” position.
The LED’s (COM 1, COM 2 and Auxiliary) will flash on once.
Connect the test leads to either set of LON communication terminals on the module under test. (see figure 2)
Note: the test lead connections are not polarity sensitive.
The tester’s status LED’s will flash approximately every 4 seconds and display the source (COM 1 or COM 2 of the
main gateway or the auxiliary gateway) of the systems Heart Beat.
OPERATION OF EQ2400HBM FOR EAGLE QUANTUM
With normal operation indicated on the Gateway display, and the Test leads of the Heart Beat monitor connected
to a given communications module’s terminals A & B (COM1 or COM2), the COM 1 LED on the Heart Beat
Monitor will light.
Note: If operating power is lost to a field communications module, a pass-through circuit is created for the network
wiring. This ensures network integrity, even if a node is down for service or has been damaged
When a LON fault occurs, the fault isolation circuitry in the affected node(s) isolates the section of the network
where the fault has occurred. The Gateway will heal the ring allowing communications to continue from COM 1
and the COM 1 LED will continue to be lit.
To isolate a fault with the Heart Beat Monitor, the Eagle Vision™ OIS software must first be used to force the LON
Override function and open the Gateway relay to un-heal the ring. To access the Override, select the Gateways’
point display in the OIS software and then select “LON OVERVIEW”, at the bottom of the display the LON
override button can then be selected. When selected, the nodes on the screens will change to a consistent color
(blue or green). This displays which nodes are receiving communications from the COM1 side of the gateway and
which are receiving communications from the COM2 side.
Using the Heart Best Monitor it is then easy to isolate in the field the point in the LON wiring where the
communications changes COM ports and the exact point of communication failure.
