BoogieBear Posted November 30, 2010 Share Posted November 30, 2010 Hi there Sorry but here I go again! I think this has been covered somewhere before but I have searched and can't find it Bearing in mind I'm a sound person and have a very limited knowledge of LX stuff Please could someone tell me in very simple steps (even if it's "no you can't!") how to make a channel fader on a 'Fat Frog' go from OFF to 100% as soon as the fader leaves the OFF position I am trying to use a lighting channel to ring a 240v AC bell (like a fire alarm type bell) as an effect So I suppose what I'm asking is can a channel fader be programmed/used as an ON/OFF switch? Thanks in advanceAnton Link to comment Share on other sites More sharing options...
boatman Posted November 30, 2010 Share Posted November 30, 2010 Either set the dimmer curve to switch or programme the appropriate channel at 100% into a submaster and use the submaster flash button. Link to comment Share on other sites More sharing options...

mar Posted November 30, 2010 Share Posted November 30, 2010 I don't know the answer, but it is probably in the manual which is available from the Zero88 site: http://support.zero88.com/main/en/download/94 Link to comment Share on other sites More sharing options...

The dimmer is not the Fat Frog, but whatever dimmer packs you are using. As far as I know the fader transfer characteristic on the Fat Frog cannot be changed from linear, however your dimmer packs might be programmable. For example the Zero 88 Chilli can be set to a variety of curves including 'switch', but don't forget to set it back after you have finished your run. It's all dependent on what dimmer packs you have. The simplest option is the flash button. This will cause the selected channel to go to 100% provided you have the Flash function set to 'Flash' and not 'Solo'. Link to comment Share on other sites More sharing options...
PaulDF Posted November 30, 2010 Share Posted November 30, 2010 You could just use a switch pack instead of a dimmer pack. Alternatively I have a 0-10v analogue source from a demux switching an opto relay providing switching for similar functions. (Mine currently connects to a contactor for switching a UV lamp).I take it you have done a risk assessment re the bell sounding like a fire alarm bell too!

nickb12345 Posted November 30, 2010 Share Posted November 30, 2010 provided you have the Flash function set to 'Flash' and not 'Solo'.Which would still set the channel to 100% as required - just turn off all the other channels at the same time Link to comment Share on other sites More sharing options...
BoogieBear Posted November 30, 2010 Author Share Posted November 30, 2010 Thanks everyone for the replies and advice Sorry boatman I missed that - I'll check on the dimmer packs when I'm next at the venue - we have different types in the rack so I'll check each type Then I'll try and learn a bit more about this 'lampy stuff' Time we upgraded the system I think!!!

I think that's what Nick meant. Link to comment Share on other sites More sharing options...
Neil Hampson Posted December 1, 2010 Share Posted December 1, 2010 Another thing that you will need to bear in mind if you are using a dimmer pack, is the type of load that you are adding (most probably a mostly inductive one from the coils in the bell) are not well suited to dimmer packs, you may find that the bell rings all the time, or possibly does not ring at all. The use of an off stage load lamp to increase the resistive load will help immensely. Link to comment Share on other sites More sharing options...
