Binary Output (terminals 7+8) LED
The LED marked " " indicates the state of the binary out-
put ("watchdog" relay) at terminals 7 and 8 (which is a
normally closed contact). Specifically, when it is lit, the
alarm contact is open; when it is dark, the alarm contact is
closed.
For a detailed description of the "watchdog" relay behavior,
see Excel Web User Guide (EN2B-0289GE51).
Binary Output (terminals 9+10) LED
The LED marked " " indicates the state of the binary
output at terminals 9 and 10 (which is a normally-open
contact). Specifically, when it is lit, this means that the
application has closed the relay; when it is dark, the relay is
open.

Excel Web received a WINK
command from L
ONWORKS;
other physical outputs are
unaffected.
In case of a problem, check if the L
ONWORKS service LED's
behavior is changed by resetting the Excel Web controller
using the reset button. Please contact Honeywell if this
does not solve the problem.
Ethernet LEDs
The Excel Web controller is equipped with two Ethernet
LEDs (see also Fig. 1 on page 2).
Ethernet Link LED
The LED marked " " indicates the Ethernet link's status.
Specifically, it is lit whenever an Ethernet jack has been
inserted into the corresponding port and the software has
established the Ethernet link. It is dark when the link has
been disabled.
Ethernet Activity LED
The LED marked " ↔ " indicates whether or not the
Ethernet link is currently active. Specifically, when it
flashes, this means that signals are being transmitted /
received on the Ethernet network; when it is dark, no
messages are being transmitted/received.
LED's L1 and L2
At present, these LED's are not in use.
Reset Button
The reset button can be pressed only using a long, thin tool
(e.g. a screwdriver). Pressing it reboots the Excel Web
controller's operating system and restarts the application.
