ITC 2106A Fixed Sequence aRGB Controller Installation Guide

ITC 2106A Fixed Sequence aRGB Controller

INSTALLATION CONSIDERATIONS

• The Fixed Sequence aRGB Controller is part of the ITC VersiControl line of aRGB controllers and lighting products (purchased separately) and will work with any aRGB product.
• Refer to individual product install instructions for additional considerations.
• Disconnect power before installing, adding or changing any component.
• To avoid a hazard to children, account for all parts and destroy all packing materials.
• Addressable lighting products require harnessing considerations for signal integrity. Please contact an ITC Sales Representative regarding your application and for assistance when designing an aRGB system.
• The fixed sequence controller does not drive aRGB signals as hard as other aRGB controllers, so shorter harness lengths can be used.
• The green Digital In and orange aRGB In wires are optional and can be used to trigger a secondary animation. Wires will come capped with heat shrink if not being used. Contact sales for more information on programming availability for these wires.

Lighting Control Options

• Option 1: Plays single aRGB animation once, then transitions to (and maintains) static color
• Option 2: Plays single animation once, then hands control of the lights over to connected controller
• Option 3: Uses digital input to trigger secondary animation or other desired lighting changes
• Option 4: Uses digital input to trigger secondary animations while also allowing connected controller to manage lights once programmed animations are complete

EMI Noise Considerations

• Installation Considerations for Preventing EMI Noise
• Electromagnetic interference (EMI) is any unwanted signal which is either radiated(thru air) or conducted(thru wires) to electronic equipment and interferes with the proper operation and performance of the equipment. All electrical/electronic components that have varying or switching currents, such as RGB lighting, create Electromagnetic interference (EMI noise). It is a matter of how much EMI noise they produce.
• These same components are also susceptible to EMI, especially radios and audio amplifiers. The unwanted audible noise that is some- times heard on a stereo system is EMI.

WHAT IS EMI NOISE?

1. Turn off LED light(s)/controller(s)
2. Tune the VHF radio to a quiet channel (Ch 13)
3. Adjust the radio’s squelch control until the radio outputs audio noise
4. Re-adjust the VHF radio’s squelch control until the audio noise is quiet
5. . Turn on the LED light(s)/controller(s) – If the radio now outputs audio noise then the LED lights may have caused the interference.
6. If the radio does not output radio noise then the problem is with another part of the electrical system.

If EMI is observed the following steps should help isolate the problem.
DIAGNOSING EMI NOISE
GROUNDING (BONDING) : How each component is connected and routed to power ground is important. Route the ground of sensitive components back to the battery separately. Eliminate ground loops. Once the EMI noise is isolated the following steps can be used to help prevent and lessen the effect of the noise.
CONDUCTED & RADIATED SOLUTIONS

• SEPARATION : Physically separate and mount the noisy components away from sensitive components. In the wire harness, separate the sensitive wires from the noisy wires.
• FILTERING : Add filtering to either the device creating the noise or the sensitive device. Filtering may consist of power line filters, common-mode filters, ferrite clamps, capacitors and inductors.

RADIATED SOLUTIONS

SHIELDING :
Shielded cables can be used. Shielding the component in a metal enclosure is also an option.

PREVENTING EMI NOISE
If you continue to experience EMI issues please contact your ITC sales representative.

Troubleshooting

1. Turn off the LED light(s)/controller(s).
2. Tune a VHF radio to a quiet channel (Ch 13).
3. Adjust the radio’s squelch control until the radio outputs audio noise.
4. Re-adjust the VHF radio’s squelch control until the audio noise is quiet.
5. Turn on the LED light(s)/controller(s). If the radio now outputs audio noise, the LED lights may have caused the interference.
6. If the radio does not output radio noise, the issue is likely with another part of the electrical system.
7. Mitigate once isolated: improve grounding (bonding) and eliminate ground loops; physically separate noisy and sensitive components and separate noisy/sensitive harness wires; apply filtering (power line filters, common-mode filters, ferrite clamps, capacitors, inductors); consider shielding using shielded cables and/or metal enclosures.
8. If you continue to experience EMI issues, contact your ITC sales representative.
