Overview

Overview
The terminal IB IL DALI/PWR-PAC is a DALI master for use within the
modular Inline-I/O system of Phoenix Contact.
It is used to control lamps via DALI ballasts according to IEC 60929. As
defined in this DALI standard, up to 64 ballasts can be individually
addressed.
The integrated DALI bus supply requires a 24 V DC supply, which can be
feed in by the potential routing contact UM or via connector 1.
Features:
• DALI master with integrated DALI bus supply
• designed for single master operation
• safe insulation of the DALI bus
• DALI bus protected against mistakenly connecting mains (up to
250 V AC)
• extensible by up to 3 terminals IB IL DALI-PAC (part no. 2897910)
• communication on local bus via process data
• indicators for diagnostics, transmission and reception
Note: This description is only valid in association with the user manual IL SYS INST UM E
of Phoenix Contact (see [1]).

Wiring Guidelines
The voltage drop between transmitter and receiver on the DALI bus must not
exceed 2 V at 250 mA. Table 3.1.1 shows wiring recommendations. The
maximum lead length between two connected DALI devices should not
exceed 300 m.

< 100 m
100 m to 150 m
> 150 m
0.5 mm² (AWG 20)
0.75 mm² (AWG 18)
1.5 mm² (AWG 15)
Table 3.1.1: Recommended cross sections of DALI bus wiring
Special bus cables (twisted or shielded) are not needed. Linear, star shaped
and mixed structures are applicable. Ring shaped structures should be
avoided.
DALI interface insulation of the electronic ballasts fulfills the requirements of
base insulation only. Therefore, SELV (Safety Extra Low Voltage) is not
granted on the DALI bus, despite the safe insulation of the
IB IL DALI/PWR-PAC.
Note: The terminal IB IL DALI/PWR-PAC is not suited when the DALI bus is externally
supplied, e.g. by other devices on the bus. In this case the terminal IB IL DALI-PAC (part no.
28 97 91 0) has to be used instead.

Note: The terminal must be supplied either via the potential routing contact UM or via
connector 1 (not both)!
For example, when the DALI/PWR terminal follows a 24 V section, the power is
automatically supplied via the potential routing contact UM – power supply via connector 1 is
not allowed then.

Fig. 3.3.1: Typical Inline station with several DALI terminals
Figure 3.3.1 shows a typical station using DALI terminals. The station
consists of several sections:
1. 24 V section
2. Terminal IB IL DALI/PWR-PAC. The DALI bus supply is fed from the
preceding 24 V section via the potential routing contact (UM). UM and
GND of connector 1 are not used.
3. Up to 3 extension terminals IB IL DALI-PAC. The DALI bus supply of
these DALI masters is fed from the preceding terminal
IB IL DALI/PWR-PAC via the potential routing contacts UDALI.
4. Separation terminal of the DALI section as end terminal. The
separation terminal is included in delivery of terminal
IB IL DALI/PWR-PAC. In any case this end terminal is required for
proper termination of this DALI section – no matter how many
extension terminals (0-3) are used!
5. Next DALI section, starting with terminal IB IL DALI/PWR-PAC, in
example without extension terminals. Because this terminal is not
preceded by a 24 V section (that is, no 24 V DC is available via the
potential routing contact UM) the DALI bus supply must be fed via
terminal points 1.2 and 1.3 (or 2.2 and 2.3) of connector 1. The
necessary 24 V DC could be tapped at connector 1 of section 2
(observe max. allowed currents). Of course, this DALI section has to
be terminated by an separation terminal as end terminal, too.

Connections
Important: Every DALI section has to be terminated by the end terminal (included in
delivery of terminal IB IL DALI/PWR-PAC). Otherwise the electrical insulation between UM /
US and the DALI bus might be compromised!
Note: The DALI busses of section 2 and 3 in fig. 3.3.1 are electrically not insulated among
one another. Normally this is no problem. However, if such an insulation is required, the
terminal IB IL DALI/PWR-PAC can not be extended by terminals IB IL DALI-PAC.
On the other hand, the DALI busses of sections 2 and 3 are electrically
insulated from the DALI bus in section 5, even if all sections use the same
24 V DC supply UM.

The input proces data words are mirroring the output words. Possible
differences at IN1:
ƒ SB indicates a peripheral fault (failure of DALI supply, short circuit on
DALI bus or failure of DALI driver circuitry)
ƒ K is set, when an unsupported command has been received via
INTERBUS local bus (no action on DALI bus)
ƒ AW is set, when a valid response of the DALI ballast has been
received. The answer field is to be interpreted in this case only
(otherwise as in OUT1)
ƒ F is set, when an invalid response of the DALI ballast has been
received (e.g. interference on DALI bus)

Functional Description
Incoming process data words are checked by the DALI terminal for changes
of the command byte (most significant byte of OUT1). For that reason, the
toggle bit is usually inverted by the application of the INTERBUS master for
each new DALI transaction.
OUT2 contains the complete DALI command to be sent on the DALI bus. The
data word in OUT2 is not interpreted in any way by the DALI terminal.
The terminal starts sending OUT2 to the DALI bus when:
ƒ a change of the command byte has been detected, and
ƒ the command byte contains a valid command "send" or "repeat", and
ƒ the DALI bus is idle (previous transaction on DALI bus completed)
Following the transmission, the terminal waits about 10 ms for an answer of
the DALI slave and receives it, should the occasion arise.
Finally, the terminal copies the process data words OUT 1/2 to the process
data words IN 1/2 and modifies the status bits SB, K, AW and F as well as
the answer byte accordingly. This acknowledgement indicates that the
terminal is ready for the next command.
When a valid DALI answer has been received, the terminal waits another
~10 ms (DALI bus settling time). Bit AW of the acknowledgement will be set
and the DALI answer will be copied to the least significant byte of OUT1.
The command "repeat" sends the DALI command in OUT2 two times at an
interval of 50 ms (start of first transmission to start of second transmission).
Beside of this, the processing is similar to the command "send".
A few DALI commands require double sending. Using the command "repeat",
this can be achieved independent of the bus cycles of the INTERBUS local
bus.
