EXCEL WEB CONTROLLER – INSTALLATION INSTRUCTIONS
Cable Types
The unit must be wired to the L
either
•
level IV 22 AWG (Belden part number 9D220150)
or
•
plenum-rated level IV 22 AWG (Belden part number
9H2201504) non-shielded, twisted-pair, solid-
conductor wire.
When possible, use Honeywell AK3781, AK3782, AK3791,
or AK3792 cable (US part numbers). See Excel 50/5000

removable terminal plug or via the L
also section "LonWorks " on page 3).
This permits individual Excel Web controllers to be
connected / disconnected from the L
without disturbing the operation of other devices.
Depending upon the chosen network configuration, one or
two terminations may be required.

BINARY INPUT AND OUTPUTS
Wiring
When wiring the two binary outputs and the binary input,
use a min. size of 20 AWG (0.5 mm
14 AWG (2.5 mm
Two wires with a total thickness of 14 AWG can be twisted
together and connected using a wire nut (include a pigtail
with this wire group and attach the pigtail to the individual
terminal block). Deviations from this rule can result in
improper electrical contact. Local wiring codes may take
precedence over this recommendation.
Binary Input
The Excel Web controller's binary input (a normally-open
contact) is not galvanically isolated. It is suitable for con-
nection with / signalling via 0...36 Vdc voltage or external
resistor or dry contact.
purpose assigned to
binary input by user
using CARE 7.0
module
high-level detection (i.e.
detection that binary
input has opened)
low-level detection (i.e.
detection that binary
input has closed)
The binary input is protected against miswiring. Specifically,
it is protected against voltages of up to 29 Vac; when
miswired, the Excel Web controller is unable to detect a
valid input signal.
Binary Outputs
The Excel Web controller is equipped with two binary
outputs.
Hardware Limits
•
A min. current of 50 mA is required to ensure a reliable
contact.
•
The binary outputs are designed for a max. continuous
current of 2 A.
•
Switching voltage = 24 Vac ± 20%.
NOTE: If inductive components are to be connected to
the binary outputs and if these binary outputs
switch more often than once every two minutes,
these components must be prevented from
causing harmful interference to radio or television
reception (conformance with EN 45014).
