Problem Troubleshooting

SERVICE

Troubleshooting is a process of elimination. First, rule out the other field factors (i.e. faulty

cables, power sources). For full technical advice and/ or parts, please contact your selling dealer.

The LED display aids in the troubleshooting of the Atomic Colors unit. The display is located on

the on the side panel of each unit.

Note:

A high percentage of problems are a direct result of poor cable and corrupt DMX control signals.

(1) The left hand vertical bar indicates that there is power (24V DC) at the unit.

(2) The middle vertical bar indicates that there is data (DMX) at the unit.

(3) The horizontal bars indicate the data signal level (DMX) at the unit.

(4) 1

bar = 25%, 2

bar = 50%, 3

bar = 75%,

(Note: The signal level changes during normal operation of the unit).

SYMPTOM POSSIBLE CAUSE SOLUTION

Unit does not respond to DMX

control, but DMX display indicator

is on.

Unit set to a wrong, or different DMX

address.

Check DMX address settings.

Unit does not respond to DMX,

DMX display indicator is off.

Bad Cable.

No DMX at power supply.

Check cable and DMX signal

Units run at different speeds Unit speed settings may be different.

Cable lengths are too long.

No cable ‘return line’.

Check all scroller speed settings.

Check the cable length and

configuration.

Ensure there is a cable return line

in the system.

Units have dim display indicators

and run slowly.

Over loading or cable runs too long.

PSU overloaded.

Check voltage levels on last unit.

Should not be below 21.5V DC.

DMX display indicator is off on

one unit.

Bad cable

Blown transceiver IC in the scroller.

Check cable

Send unit back for repair.

Display Indicators appear OK but

gel string does not move.

Mechanical (or electrical) failure in

the unit.

Turn unit on and off.

Return unit for repair.

Gel burns too quickly Fans have failed or are too slow.

Make sure the power supply for the

Atomic Colors is connected and

switched on.

Check fans are operating.

Note

The color transport system employs an opto-electronic system for accurate positioning of the gel.

When the unit initially receives power, it will go through a calibration sequence. The purpose of

the initial calibration sequence during power up is to determine the total length of the gel string,

and therefore the position of the different gels.

Please note that over time the gel string may warp slightly. This may alter the positions of the

gels relative to their pre-programmed DMX values and therefore some ‘fine-tuning’ may be

required.
