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.
 Locate the fixture in a well ventilated spot, far away from any flammable materials and/or liquids. The
fixture must be fixed at least 50cm from surrounding walls.
 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.

FUNCTIONS

1. CHANNEL OUTPUTS: Each channel output has its own output socket to connect any resistive and/or
inductive projector(s) or small light effects.
2. CHANNEL FUSES: Each channel is equipped with a fuse. Always replace a blown fuse with a fuse that
has the same characteristics! (250V/5A fast)
VERY IMPORTANT NOTE!
It's very important to know that the maximum load for each channel is rated at 5A or 1100Watts.
However the total load for all 4 channels may not exceed 16A or 3600Watts!
3. POWER INPUT: mains input cable, make sure the local voltage is 230Vac and the projectors (and/or
light effects) are properly connected to the channel output sockets (1) before you connect this cable to
the mains wall socket. The maximum total load is 16A or 3600Watts.
4. INPUT FUSE: Always replace this fuse with a fuse that has the same characteristics! (250V/15A slow)
5. DMX OUTPUT: 3pin female XLR-connector used to connect the PB41 with the next unit in the DMX
chain.
6. DMX INPUT: 3pin male XLR-connector used to connect universal DMX-cables. This input receives
instructions from a DMX-controller.
7. DMX PRESENT LED: this LED indicates if the unit receives a DMX-signal on the DMX-input(6):

 LED is on: no DMX-signal detected on the input.
 LED is blinking: DMX-signal detected on the input
8. DMX ADDRESS SETTING: used to set the DMX starting address of the unit. Below you will learn how to
set the DMX-address:
How to set the DIP-switches to obtain the right starting address:
Remove the protective cover from the DIP-switches (8) and (9). You will see the DIP-switches. Refer to
the table below to learn to set the DMX-address.
Dip #1 #2 #3 #4 #5
Value 1 2 4 8 16
You can combine the values of these switches to become any starting address between 1 and 512:
 switch 1=ON
Begin address = 01
 switch 1+3=ON
Begin address = 05
 switch 1+4=ON
Begin address = 09
 switch 1+3+4=ON
Begin address = 13
...
 switch2+3+4+5+6=ON
Begin address = 62
9. DIM / SWITCH SETTING: Remove the protective cover from the DIP-switches (8) and (9). You will see
the DIP-switches to set each channel individually in dim or switch mode:
 DIM mode: use this mode when you connect lamps (projectors) to this output channel. You will be
able to dim the output smoothly between 0% and 100%.
 SWITCH mode: use this mode when you connect small light effects to this output channel. You
can toggle the output between ON (100% output) and OFF (0% output). Now you can switch small
light effects on/off with your DMX-controller.
10. TOP SECTION ADAPTER: used to put the PB41 easily on top of a light stand equipped with a standard
35mm top section. (example: JB Systems® LS64 light stand) Optionally you can also buy a standard
28mm TV-spigot.
11. SLIDING MECHANISM: used to distribute your projectors evenly over the PB41.
