Unfortunately I don't have a pic of the back.Another question : is a socapex for lighting drawing from 3 phases? If yes I will have a follow up question between relation of c5 and socapex in terms of phase reverse at the distro.

example on the install CS800 is turned to ABC ( running in the correct phase , correct directonal control) cs800 C5 is disconnected and on the dismantle, CS 800 is plugged back in , only this time the CS 800 needed to be turned to CBA. ( phase reversed). (1)what caused this?(2) also what is...

What is the reason for a CS-800 to be in reverse at times? http://www.skjonberg.com/products/manual_hoist_contols/images/cs-800_with_pendant.jpg ex: same building and setup; Transformer? or generator? ( only has a twistlock and camlock- electricity coming from the building) connected to a distro...

Which crew member woud you rather invest time in to show the ropes?One can move quickly but talks alot , comments a lot or the other who doesnt move as quickly but is quiet, listens more than talk. Both of them show wilingness to learn.

Usually take out cotter pins while still at working height , land truss and hammer out 4 pins.I was wondering if it would be possible to hammer out 2 bottom pins only while at working height ? ( see image 1)** I have seen on a big arena show where the truss flew to trim height with only 2...

in this setup person x ( w/ harness) is on top of a scaffold ladder (20-25 ft) and would have to reach outside as shown in drawing (location A) Scenario without a ground person1. Would that ladder tip over if person x is in location A? B? C( approx 10ft off ground)2. Lets assume ladder...

we always lower truss to working height and strip lights, cables etc. and then land truss on ground before unbolting. I was wondering if when everything is stripped from truss ,would it be safe to only loosen bolts and then land the truss on ground?

I used Sapsis book to make a calculation for UDL in a cantilever.. see image ..-Truss chart is christie 12 inch truss.- span of truss is 32'- A 1 is left of truss 12' in and A 2 is at the end on right.- UDL is a led wall 14x8 at 18.4 lbs = 2060 lbsI got A 1 at ~1440 lbs and A 2 at...

I found the following confirmed infos: - truss chart applies to the truss being used. -the build is Cornerblock , 2', 8 ' , 8' , 8' and corner block = 26' - the wall is 10x6 = 60 panels weight of 1 panel = 18.4lbs = 1104 lbsBased on the truss chart Uniform load at 24' is 1128"lbsThe legs...

that was tried. I forgot to mention that we used group B by itself into opto and board was working.so opto works with only 1 output but doesnt work when 2 outputs are used. I am assuming its a broken opto? haven't had chance to test the opto more in different configuration such as using...

We had 4 lights daisy chained ( group A ) and plugged into an opto. The board had control.Then we had a second set of lights ( group B ) daisy chained and into the opto. All fixtures addressed same.The problem was board didn't have control of group B. We thought it was a bad DMX so we...
