EXCEL WEB CONTROLLER – INSTALLATION INSTRUCTIONS
Terminal Blocks
The Excel Web features two rows of removable terminal
blocks (located at the front left-hand side; see Fig. 1 on
page 2) for the connection of cables to the two binary outputs and the binary input as well as for connecting
L
ONWORKS and the power supply. A nearby sticker provides
an overview of the terminal assignment (see Fig. 2).

Maximum torque for fastening the wiring terminal screws is
0.5 Nm (4.5 lb-in).
Table 1 provides a more-detailed explanation of the
terminals and their functions.

1+2 power supply (24 Vac ± 20%, 19.2 to 38 Vdc)
3+4 a binary input (normally-open, 36 Vdc; pin 4 is the
signal ground), freely configurable (using CARE
7.0) to read input from either 1) a field device or 2)
a collective alarm input or 3) a 2
controller whose duties it could then assume in the
event of its failure
5+6 LONWORKS
7+8 a binary output / "watchdog relay" (SPDT, normally
closed, 24 Vac, max. 2 A permanent load), per-
manently configured to write output to an alarm
device (which can then signal that Excel Web is
malfunctioning)
9+10 a binary output (potential-free contact, SPST,
normally-open, 24 Vac, max. 2 A permanent load),
freely configurable (using CARE 7.0) to write out-

LonWorks Interface
The Excel Web is equipped with a LonWorks interface
(specifically: an RJ45 jack) permitting communication on
L
ONWORKS networks.

There are two methods of connecting the Excel Web controller to the L
method can be used):
ONWORKS networks (both or either connection
•via terminals 5+6 and 11+12 of the terminal blocks
(see Fig. 1 on page 2); and/or
•via the corresponding jack located to the right of the
terminal blocks (see Fig. 3).
See also section "LonWorks Service LED and Service
Button" on page 4 for details on the corresponding
L
ONWORKS service LED and one LONWORKS service button
Ethernet Interface
The Excel Web controller is equipped with a 10/100-Mbaud
Ethernet interface (specifically: an RJ45 jack) permitting
communication (as per IEEEC 802.3) on BACnet/IP networks.

When thus connected, the user sitting at a platform hosting
EBI can thus e.g. view and edit the time programs, trend
values, etc. of the other devices in the BACnet/IP network.
This Ethernet jack conforms to the specifications of the
following two Ethernet sub-standards:
•100Base-TX (twisted pair / star wiring; 100 Mbaud
Ethernet based on Manchester signal encoding over
category 5 or better twisted pair cable; max. segment
length = 100 meters) and
•10Base-T (twisted pair / star wiring; 10 Mbaud
Ethernet based on Manchester signal encoding over
category 3 or better twisted pair cable; max. segment
length = 100 meters).
RS232C Serial Interface Ports
The Excel Web controller is equipped with three male 9-pin
sub-D jacks into which corresponding female 9-pin sub-D
plugs can be inserted for various different purposes (see
following sub-sections). These ports allow data transmission rates of 9.6, 19.2, 76.8, or 115.2 kBaud (the
default).
Fig. 5. RS232C serial interface
Using CARE 7.0, the user can configure the specific
desired data transmission rate of each individual RS232C
port; it is thus possible for the three ports to operate simultaneously at three different rates.
Port 1 (Factory Service Interface)
Port 1 is intended for the connection (as needed) of a platform for the purpose of servicing (in the factory, only) the
Excel Web controller. In this context, "servicing" comprises
a group of different activities including:
•updating portions of the Excel Web controller's
Operating System (namely: LINUX, BACstack, Apache
Web-Server) and
•diagnostics (Linux, firmware).
