Installation & User Instructions
4 Channel Dimmer
HES99300
The Helvar Electrosonic HES99300 is a four channel
dimmer unit having a total current capacityof 10A. The
dimmer can control the following load types: incandescent
lamps, low voltage halogen lamps with dimmable
conventional and electronic transformers, 26 mm
fluorescent tubes or compact fluorescent tubes with Helvar
EL-FD electronic ballasts, and 3 wire dimming ballasts for
fluorescent tubes.
The dimmer can be controlled with the Ambience Master
Panels or from a Helvar Electrosonic Imagine system, or
from 0-10V analogue rotary controls or sliders. Remote
panels including one infra-red remote control can be
connected to the Master Panel.
Easy light level adjustment of the four channels is done
directly from the Master Panels. The minimum level and the
fade time adjustment of the dimmer is carried out at the
panel.

Load Types
Note 1)
Transformers for low-voltage halogen lamps must be approved for dimming use by the transformer manufacturer.
Note 2)
Helvar recommends lamp loading of the transformer to no more than 80% of the nominal transformer power, unless otherwise specified
by the transformer manufacturer. For example, a 500 VA transformer should not be loaded to more than 400W of lamp load. In
addition, the transformer has to endure short-circuit resistance or it must be equipped with a thermal protection on the primary side. The
thermal protection is to be of non-resettable type or manually resettable only.
Note 3)
The leakage current to the earth of the electronic ballast is about 0.5 mA. Due to harmonic currents, the leakage current can rise up to
5.0 mA/ballast when dimmed. This has to be taken into account in those installations where earth leakage circuit breakers are used. For
example, no more than six ballasts can be connected to one 30 mA fuse.

Installation
Before installation, isolate the electrical supply at the main distribution board.
Install the dimmer to the mounting surface using four screws. Connect the wires according to the wiring diagrams using only specified
cable types.
The display and function buttons mounted to the dimmer front panel are only used when connected to an Ambience 24 or an
Imagine system. For use within a 4 Channel system, do not change factory settings.

Channel Address Mode
This mode enables the addresses for channels A, B, C and D to be defined.
The HES99300 supports the following addresses:
 001 - 024 for use with the Ambience 24 Channel Lighting System.
 001 - 128 for use with the Imagine Lighting System.
 129 - 250 these are not currently used, and should not be selected unless otherwise instructed.
 251 - 254 for use with the Ambience 4 Channel Lighting System.
 255 for use when analogue control only is required.
 000 for test purposes only.
IMPORTANT NOTE: The HES99300 will not respond to S-DIM commands from an Ambience 24 or an Imagine System
if the channel addresses have been set incorrectly.
Changing the Channel Addresses
1. Press and hold the pair of buttons for the corresponding dimmer
until the display shows the Channel Address Mode, then release
both buttons.
For example, the left-hand pair of buttons are for channel A.
2. Press the top button to increase the address number or the bottom
button to decrease it.
To leave the address as it was previously, go to step 4.
3. To store the new address now displayed, press and hold both
buttons until the display briefly shows '888' to confirm that the
new value has been stored in the HES99300 internal memory.
4. To view or change the address for one of the other channels in the
block, repeat steps 2 and 3 using the appropriate pair of buttons.
5. If no further settings need to be changed, release the buttons; the
display will revert to Output Level Mode after ten seconds.
OR
Retain pressure on both buttons until the display changes to the
next required mode.
Procedure Display & Buttons

If you experience any functional problems after installation, please check
the following.
Check control wiring is to specification.
Check all connections are made in accordance with the wiring diagrams.
Check minimum levels have been set appropriately.
Ensure electricity supply is within the range allowed.
Use override facility to test dimmer output.
If a problem persists please contact Helvar Electrosonic or an appointed
distributor.

S-DIM
S-DIM is an Electrosonic control protocol designed for
use with the Electrosonic Imagine system, which can be
used to connect HES99300 dimmers to an Imagine
system. The HES99300 would then act as a remote 4
channel dimmer accepting control from the Sceneset
control processor.
