Product Description

The Digidim 474 is a four-channel ballast controller fitted

with high-inrush relays rated at 16 A per channel, which

handle short, high-peak currents during switch-on of loads.

The outputs can be configured to match common ballast

control loads including 1–10V, DSI®, and DALI-broadcast.

The outputs can be configured independent of, or paired

with, a relay channel.

The unit can operate with either a Helvar Digidim or

Imagine lighting control system and is DIN-rail mounted for

ease of installation.

‘Power’ indicator

The ‘Power’ indicator (top segment of the middle digit) is

always on when the 474 ‘Status’ display is active.

‘SDIM/DMX Activity’ indicator

The ‘SDIM/DMX Activity’ indicator (centre segment of the

middle digit) is normally off, and flashes on intermittently

if any SDIM/DMX activity (communications) is directed to a

channel within the ballast controller.

Output mimics

The output mimics (1, 2, 3 and 4) are illuminated when the

relays/outputs are on, and not illuminated when the relays/

outputs are off.

Key and LED Descriptions:

Power Up

‘Status’ Display

During power up, the following sequence is displayed on the LED Control Panel.

Each display is held for one second. At the end of this sequence, the ‘Status’ display appears.

all the menus.

Cycle through the menu:

1. Press both buttons simultaneously to cycle through the

menus.

Tip! To cycle through the menus quickly, keep holding down both

buttons.

Select the desired channel to modify:

2. At your chosen function, quickly press up or down button

to scroll through the channel destinations. These are the

channels that will be affected by the following settings.

Note: Select ‘ALL’ to alter all channels simultaneously.

Modify function settings:

3. Hold up or down buttons to alter the levels, settings, fade

times, output modes (dependent on function activated).

For more details, see the ‘Configuration’ section on

page4.

Note: LEDs blink if the value has been changed and not yet stored.

Various settings can be configured via the control panel.

‘Status’ Display / Set Channel Level

Set Channel Levels (0 % – 100 %) by using the push buttons in the ‘Status’ menu. Select the

channel(s) to change, and then hold the up or down button to alter levels. For more information,

see the ‘Quick Start Guide’ section on page7.

Note: You can access ‘Status Display / Set Channel Level’ mode while the device is in override mode,

but it is not possible to change the channel levels.

Set SDIM/DMX Address

Set the SDIM or DMX address for each channel.

Select bas to set the SDIM or DMX base address.

SDIM: 252 addresses available.

DMX: 512 addresses available.

Note: DMX updates are disabled while using manual control.

Set DALI Address

Set the DALI address for each channel. Select bas to set the DALI base address.

DALI: 64 addresses available.

Enable/Disable DMX

Enable or disable DMX from this menu.

When DMX is enabled (‘On’) it will use the SDIM address.

There is no channel select option; it is a global setting.

Note: DMX is disabled by default.

Output Table Selection

The outputs can be configured to match common ballast control loads via the ‘Output Table

Selection’ ( ) menu.

The following table gives a brief summary of output types.

Minimum Fade Time

Set the minimum fade time for the channels.

Select the minimum fade time for each channel individually or ALL channels simultaneously.

Minimum fade time can be set to: 1.00 second, 0.50 seconds, 0.15 seconds and 0.02 seconds.

5Helvar 474 4-Channel Ballast Controller: Installation and User Guide

Override Level

The override level can be configured for individual relay channels or ALL channels and ranges

from 0 to 100. It can be manually tested via the override test function (‘Ort’)

Note 1: When SDIM/DMX is connected, the override settings in the router (configured using Helvar

Designer software) will take precedence over the device’s override settings unless you

configure the software to use the device override settings.

Note 2: When the unit is running in override, the left decimal point is illuminated and the middle

digit of the screen flashes in the ‘Status’ display.

Channel Pairing

The output and relay channels are paired by default in a simple, one-to-one format.

Configure the pair, or separate (‘SEP’) the channels as required.

Note: Currently it is not possible to set channel pairing using Designer software. All channel pairing

must be manually configured at the device.

Override Test

Test that the override level (set in the previous mode) functions as required, by choosing ON or

OFF. The unit performs as if an override has been caused by the override input connection.

Note 1: By switching this setting to ON, it will not be possible to manually edit the channel levels in

the ‘Status Display / Set Channel Level’ menu.

Note 2: To change the channel levels, ensure that override is switched off.

Restore to Factory Default

Hold the up or down buttons for 10 seconds in this menu.

The decimal points will light up in sequence, and then all LEDs will be on for 1 second to

confirm that factory settings have been restored.

Note: Restore to Factory Default will permanently delete all the existing manually configured

settings.

Communications Error (SDIM/DMX only)

ErCindicates a problem with the SDIM or DMX communications. Check wiring and

terminations. Make sure no two channels have the same addresses on the network, and that

the SDIM/DMX mode is selected correctly.

Outputs Error

Er0indicates a problem with the output stages. Please contact Helvar Support for assistance.

Troubleshooting and Error Messages

If an error occurs, please contact Helvar Support (see www.helvar.com for details).

These details may be of assistance should an error message be displayed:

• Do not connect DALI and SDIM/DMX at the same time.

• If DMX does not work, make sure that it has been switched on in the dMX menu.

Important Considerations

6 Helvar 474 4-Channel Ballast Controller: Installation and User Guide

Note 1: Use the Helvar remote control unit with a Digidim control device to put the device into ‘Physical Selection’ mode. Refer

to the ‘ Digidim Lighting Control – Designing, Specifying and Installing’ System Manual.

Note 2: The ‘Physical Selection’ display is identical to the ‘Status Display / Set Channel Level’ display, except for the decimal

point flashing.

1. Put the device into physical selection mode.

The centre decimal point on the display screen will flash to indicate that the device has entered ‘Physical

Selection’mode.

2. From the control panel, repeatedly press ‘up’ or ‘down’ button to scroll between channels.

The selected channel mimic (s) will flash.

3. To physically select the channel, hold the ‘up’ or ‘down’ button.

The centre decimal point will stop flashing for two seconds to indicate a successful programming.

4. Repeat step 2 and 3 for each channel, as necessary.

5 End ‘Physical Selection’ mode (at the device).

The ‘Status’ display will appear.

DALI Physical Selection

Physical selection mode is activated using a Helvar remote control unit. It allows loads and controls to be grouped together

without the use of programming software. Refer to the equipment instructions for details.

Follow these steps to use the module to identify a piece of equipment using physical selection mode.
