Lutron HOMEWORKS 4 Serie Installationsanweisungen Seite 2

Installation
1. Ensure Mains-voltage cover in HWI-LV24 enclosure is
securely installed. Locate and lock supply breaker in the
OFF position before installing processor assembly.
Danger - Wiring with power on may result in
personal injury.
2. Install processor assembly in the enclosure: The
HomeWorks 4 Series Processor is attached to the
® TM
HWI-LV24 enclosure using four mounting keyholes and
the mounting screws provided.
The 4 Series Processor mounts
in the upper left corner of an
HWI-LV24 enclosure.

(shown with cover installed).
3. Set processor address. Set processor address using
Configuration Switch. The HomeWorks Utility will prompt
the programmer if any subsequent changes to the config-
uration switches are required. The factory installed
Dimmer Hub is already addressed to "1".
Table 2 - Configuration Switch Functions
DIP Switch Function
1 Boot Mode. Unless prompted by the
HomeWorks Utility, this switch should always
be in the DOWN position.
2 Diagnostic. This switch should always be in
the DOWN position.
3 UP = 9600 Baud, DOWN = Auto Baud
detect.
4 Battery disconnect. This switch should
always be in the DOWN position.
5-8 Processor Address. See Figure 3, below.
Example: Setting Switch #7 ON.

4. Connect to HomeWorks lighting controls. Connect the
communication wiring from the dimmers to the factory
installed Dimmer Hub (see Figure 4, page 3). Connect
the buses according to the bus assignments that were
made using the HomeWorks Utility. Gray and violet con-
nections are marked on the printed circuit board.
5. Connect Dimmer Hub links: A harness connects Link 4
to the factory installed Dimmer Hub. If additional HWI-
H48-CE boards are to be controlled by this processor,
the communication link to those boards should be con-
nected into the same terminal block. Do not connect ter-
minal 2 to an HWI-H48-CE. If the H48 Link has a cable
length of 15 m (50 ft.) or more, LT-1 link terminators must
be installed across MUX and MUX (terminals 3 and 4) at
both ends of the link. Refer to HWI-H48-CE instructions
(see Figure 5, page 4).
Note - Links 4, 5 and 6 are configurable for use as
Keypad Links, GRAFIK Eye
links are configured by the HomeWorks Utility.
6. Connect Inter-processor Link (multiple processor
installations only): The Inter-processor Link is used for
communication between HomeWorks Processors.
Connect control wiring to the Inter-processor Link (Link
2), if required. Do not connect terminal 2 (see Figure 5,
page 4). If this processor is to be the first or last proces-
sor in the daisy chain, attach one of the LT-1 link termi-
nators provided across the MUX and MUX (terminals 3
and 4—see Figure 5, page 3). If LT-1 terminators are
unavailable, a 1/2 W resistor between 100 and 150
Ohms may be placed across terminals 3 and 4 to provide
termination.
7. Connect GRAFIK Eye / WPM links: If GRAFIK Eye pre-
set dimming controls or Wallbox Power Modules are to
be controlled by this processor, connect the communica-
tion wires to Link(s) 4, 5, or 6 as configured in the
HomeWorks Utility. Do not connect terminal 2.
8. Connect Keypad links: For keypads or keypad link
devices (e.g. HWI-CCO-8) that are to be controlled by
this Processor, connect the communication wires to
Link(s) 4, 5, or 6 as configured in the HomeWorks Utility.
Note: Connecting keypads or keypad link devices to links
other than Link 6 requires an additional power supply.
9. Connect power. Plug the power input harness terminals
(yellow wires) from the HWI-LV24 enclosure onto the
power feed lugs on the 4 Series Processor. Connect plug
from adapter to Link 6 Power connector. Plug adapter
into receptacle in bottom of HWI-LV24. The 4 Series
Processor has battery-backed memory and timeclock
devices. The battery provides power to these devices
during power outages and other temporary power inter-
ruptions. In vacation homes and other residences which
are not continuously occupied, the 4 Series processor
MUST be powered by a circuit that is never turned off
even when the residence is unoccupied.
10.Turn power ON. Restore the supply breaker to the ON
position.
