3.2 Control Input
The dimmers are designed primarily to accept control signals conforming to the
DMX512/1990 protocol. Connection is made through the DMX512 Input connector
located on the front panel. A Thru connector located next to the Input, allows the
connection of the dimmer to other DMX512 devices downstream. The Thru connection
is passive and allows for the pass through of the DMX512 signal, even if there is no
power to the dimmer.
The IPRO/T model has all DMX512 connections internally
wired to a 4mm² pressure clamp screw terminal connector.
However the LINK connector on the front panel remains as
this still allows for software upgrades as detailed in Section
5.2.
LED’s on the front control panel indicate the condition of
the incoming DMX data. Valid data is indicated with a
Green “DMX data” LED. Bad data is indicated with a Red
“DMX error” LED.
It is advisable that if this dimmer is the last DMX512 device
in a long data stream, then connect a “Terminator” in the
“Thru” connector to stop any possibility of reflections on the
DMX512 Network. The “Terminator” can be a mating plug
with a 120 Ohm resistor soldered between pins 2 and 3.
3.3 Load Connection
The iPAK/A dimmer is only available as an Australian version, providing twelve 10
Amp HPM No. 38 Sockets, whereas the iPRO dimmers offer a wide selection of output
load connectors to suit the many applications and countries that these dimmers are
sold to. For Australian versions, the iPRO/A is supplied with twelve 15 Amp HPM No.
38 Sockets, whereby the iPRO/6A is supplied with six 25 Amp HPM No. 38 Sockets to
suit the higher current capacity per circuit. For European versions, twelve Shuko 2 x 16
Amp Sockets (iPRO/SE) or 24 x 15 Amp UK sockets can be fitted (iPRO/UK).
The hard-wired version of the iPRO is
supplied with three detachable load
connectors. Each connector contains
four dimming circuits where each circuit
consists of three (Active, Neutral, Earth)
4mm² pressure pad screw terminals.
The iPAK is a soft-fired dimmer, and as
such, is suitable for most resistive type
loads. The iPRO is a hard-fired dimmer
meaning it is very suitable for resistive
loads as well as most inductive loads
such as fans, motors, ballasts and dimmable fluorescent tubes. Care should be taken
when driving inductive loads as not all of these types of loads can be dimmed. If you
are in doubt to the dimmers suitability for the intended application, please consult LSC
Lighting Systems or your nearest Distributor for further information.
Under all circumstances during the operation of the dimmer, it is highly advisable not to connect or disconnect the
load while live, to prevent potential damage to the dimmer, the load connectors or to the load itself.
