OVERHEAD RIGGING

Important: The installation must be carried out by qualified service personal only. Improper

installation can result in serious injuries and/or damage to property. Overhead rigging requires

extensive experience! Working load limits should be respected, certified installation materials

should be used, the installed device should be inspected regularly for safety.

Make sure the area below the installation place is free from unwanted persons during rigging, de-rigging

and servicing.

The device should be installed out of reach of people and outside areas where persons may walk by or be

seated.

Before rigging make sure that the installation area can hold a minimum point load of 10times the device’s

weight.

Always use a certified safety cable that can hold 12times the weight of the device when installing the unit.

This secondary safety attachment should be installed in a way that no part of the installation can drop

more than 20cm if the main attachment fails.

The device should be well fixed; a free-swinging mounting is dangerous and may not be considered!

Don’t cover any ventilation openings as this may result in overheating.

The operator has to make sure that the safety-relating and machine-technical installations are approved by

an expert before using them for the first time. The installations should be inspected every year by a skilled

person to be sure that safety is still optimal.

ELECTRICAL INSTALLATION

Important: The electrical installation should be carried out by qualified personal only,

according to the regulations for electrical and mechanical safety in your country.

Electrical installation for 1 standalone unit:

Insert the mains cable. The unit starts working immediately in the last selected mode.

Refer to chapter HOW TO SETUP to learn how to switch between the different working modes.

If you like, you can control the unit using the optionally available:

COB-4BAR FOOTCONTROL: foot controller, perfect for music bands etc.

LEDCON-02 Mk2: (must be Mk2 version!) perfect for use by DJs!

See chapters HOW TO SETUP and OPERATING INSTRUCTIONS for more information.

ENGLISH USER MANUAL

JB SYSTEMS®5/16 COB-4BAR

Electrical installation for two or more units in master/slave:

Connect several units together using good quality balanced microphone cables. The unit that has no

cable connected to its DMX-input is the “master”, the others are the slave units.

Make sure that all units are connected to the mains.

Refer to chapter HOW TO SETUP for more information.

Done!

Note: of course you can always add a foot controller or LEDCON-02 Mk2 to the master for more control.

Electrical installation for two or more units in DMX-mode:

The DMX-protocol is a widely used high speed signal to control intelligent light equipment. You need to

“daisy chain” your DMX controller and all the connected units with a good quality

balanced cable.

To prevent strange behavior of the light effects, due to interferences, you must use

a 90Ω to 120Ω terminator at the end of the chain. Never use Y-splitter cables, this

simply won’t work!

Make sure that all units are connected to the mains.

Each light effect in the chain needs to have its proper start address so it knows which commands from

the controller it has to decode. In the section HOW TO SETUP you will learn how to set the DMX

addresses. If for example you use the 4 channel DMX mode, a possible address setup could be: unit1 =

001 ~ unit2 = 005 ~ unit3 = 009 ~ unit4 = 013 ~ etc.
