The TA 10 is highly flexible in what you can do with it but the easiest way is to use the event relays and leave the cue relays for customisation.
The events are common to all shows so...
Event 1 happens when you press start.... it turns on the Motor and Xenon lamp. Put your lights down on this event.
Event 2 happens 7 seconds after event 1, it opens the shutter and turns the alarms on.
Event 3 happens when your end of show cue goes thru. You select which cue you want to use and connect the yellow pair onto the terminals. I always use the middle cue, number 2, for this personally.
Event 4 happens 'x' seconds after event 3. You set the delay 'x' using the dip switches on the top circuit board. The shutter will then close after 'x' seconds. The alarms are turned off waiting for the film to run out, end of film, or another interval cue to restart event number 1.
Event 5 is film run out and stops the projector.
An alarm event triggers events 3, 4 & 5.
So put your lights down onto event 1 and your lights up onto event 3. You will need to set the delay for event 4 to match your curtains closing speed if you have them. Also set the up & down fade rate to match. If you can't set the fade rates you may have to use a cue to control the lights directly. But avoid this if possible as it will use up two cues you could use for other functions. It's also less work when cueing up in the first place.
The manual explains all of this in some detail so if you don't have one its available from CA's web site and on Film-Tech.
You will need to assign which relays are triggered by each event so sit down and write out what you want to happen with each event and work out how many relays you need to tie to an event. Each relay has two sets of contacts. As there are only six event relays available you need to give careful consideration to how you are going to assign them.
You can easily tie an event relay to more than one event if you need to... but you MUST use diodes if you want to do this. If you are only tieing a relay to a single event you can use a simple wire jumper. I ALWAYS use diodes so there is no confusion later.
NOTE! You can tie a CUE relay to an EVENT relay or visa versa
if you need to but you MUST use a diode for this. Doing this can extend the number of functions controled by an event or cue.
I would use cue 1, 3, 5, & 7 for functions that happen when film sound is NOT active ie on lacing leaders. That way there is no loud thump as the cue goes thru.
Cue 2 for end of show , leaving cue's 4 & 6 for functions you want to operate whilst on screen.
This may not work out in practice but it is preferable.
My cueing system has always been...
Cue 1 Masking to 1.85. Placed on leader.
Cue 2 End of show / Restart show.
Cue 3 House lights off. Placed on leader.
Cue 4 House lights to low. Placed at start of credits.
Cue 5 Masking to Scope. Placed on leader
Cue 6 Not used
Cue 7 All stop. Placed on feature change run out after ads etc.
Cue 7 was wired thru a normally open contact so we could select to stop during the feature change if we needed to. We had quite a long feature change to allow for stopping and splitting the programe on advert change days. Other wise the projector continued to run until the next middle cue went thru and started the show again.
Cue's 2 & 5 were used for masking control. Cue 2 was applied to the leader and taped over so it was permanent. If the film was in scope you appled the other side of cue five on top of the tape. This way it was easy to change a cue back to 1.85 by simply peeling off the cue from the opposite side.
You can see that there are no sound track cues while on screen. There is only ever a need to put a maximum of two cues onto a film itself. The company I worked for liked the house lights rased to low at the start of the credits. If you don't do this then you only need apply a single middle cue. Everything else is on lacing leaders and in house titles so you don't have to constantly apply cue's.
Hope this helps. Happy to help further if needed.
