1. Introduction
1.1 Product range
This handbook describes the operation and
programming for the IES EC24 & EC12 rack
mounting dimmer pack. The dimmers covered by
this handbook are:
9602 EC12I, 12 x 1kW, 20A three
phase input, 2 x harting output
9804 EC24I, 12 x 2,5kW, 40A three
phase input, 2 x harting output
1.2 Main features of the EC dimmer
The EC dimmer is a fully digital triac dimmer pack
with fuse over current protection per circuit. LED
Status information per channel. This dimmer is a
Low cost solution for a wide range of destinations.
2. Unpacking and installation
2.1 Unpacking & checking
The EC dimmer pack is a self-contained dimming
system and only requires a suitable mains input
connector.
The EC dimmer pack is packed to withstand normal
transportation, but before operating the unit, check
there is no sign of transit damage which could affect
the operation and safety of the dimmer.
2.2 Positioning
The EC dimmer pack is an extremely versatile
dimmer, and can be incorporated in a 19” equipment
rack, or used as a portable dimmer. It is designed for
forced ventilation cooling and care must be taken to
ensure adequate ventilation especially when the EC
is built into a cabinet. The EC is supplied with
mountings suitable for 19” equipment enclosures,
and accommodates 2U of panel space.
2.3.2 Power output connections
The EC has a cable 5 x 4mm2. Connections to the
loads are simply made by fitting the appropriate plug
to the load cable.
2.3.3 DMX data signal connections
The dimmers are controlled using DMX 512. This is
connected by a two-pair and shield high-speed data
cable with XLR 5-pin connectors (male = input;
female = output).
Pin connections are:
1 0V shield
2 DMX +
3 DMX 4 - DATA
5 + DATA
The DMX network supports up to 32 PR-6 dimmer
packs (192 dimmers in total) connected to each
DMX line. For larger installations where more DMX
lines are required, the use of a DMX booster/isolator
is recommended. Any booster/isolator used has to
accommodate bi-directional data on pins 4 and 5 for
DimSTAT to operate. Suitable boosters are IES
code 9601 (5 channels) or 9815 (10 channels).
Termination is required for DMX data on all
networks. The last DMX output socket in the line has
to be terminated with two 120Ω 1/4 Watt resistors
connected between pins 2 and 3 (DMX). A ‘dummy
plug’ XLR male connector with the termination
resistors fitted is recommended for this purpose.
2.4 Safety
Even though the EC dimmer pack is equipped with
Fuses per channel, all normal electrical safety
procedures must be applied. Do not use the dimmer
if the mains input cable has been damaged, or the
body of the case is not intact. Do not expose the unit
to rain or moisture. To avoid electrical shock, do not
open the cabinet. Refer servicing to qualified
personnel only.
2.3 Connections
Note: All electrical connections to the EC dimmer
pack must be made by a suitably qualified
person.
2.3.1 Power input connections
Input power is supplied via a 3-phase, neutral and
earth 4mm
socket, such as a 32A three phase CEE17, is
recommended.
