If you are referring to the count down ped, it will re-learn every time power is turned off and back on again.

What do you think the problem was with the ped you were talking about in your earlier post...not working right till you conected it to a NEMA cabinet???

For some reason it didn't like the EM controller. I do not know why and never bothered to find out.

Hey Jerry,

Was it not counting at all? Or counting erratically? It could be that the electronics inside were getting goofed up with a slower flash rate on a mechanical controller versus the more standardized flashing rates of NEMA.

The internal counter simply counts the on/off cycles once per second. Some will work with the slower flashing rate, others will give you problems.

I just don't remember anymore. It has been a while since I hooked that signal up to my EF-15 to test it. It's now permanently hooked up to my EPAC.

Can anyone suggest a flasher/relay that would work well for this application?

Part number and where it can be purchased??

Thanks,

Ok, could I use an "in line" flasher and tie in to the signal "yellow" and tie that to the "don't walk" on the peds?

The in line flasher idea will work. We have isolated contacts in our EF-20 controllers, but the result is the same. It won't work with a 6 interval cam that half cycles (you need 8) so you need to use the 12 intervals on the cam (there will be some dummy intervals) but that's all there is to it.

This links to the cam chart that we use. Circuit numbers can change to fit your layout but the cam cutouts would be the same.

I'm working on a cam chart for my type F controller, I have 14 new cam's comming from GTE so I'll be starting out fresh.

Joe, the cam chart that you sent me has a GYR configuration, mine is RYG. I think you said that cam chart was for an Eagle controller. I charted my current cam configuration just to compare (its a 6 interval) and it looks backwards compared to the one that you sent, is that the difference between GYR and RYG???

Also, does it matter where I start on the chart?? Do I start with R1 on the first (1) interval on the cam or the last (12) interval, since the cam rotates clockwise??

Once I get the main street/side street RYG's and the DW/W and the flashing DW all figured out, I should have some extra circuits for what I think you call left clearance (protected left turn). I would like to use this option on a third phase if possible? This option can be added later as long as the circuits/intervals are available......correct??

If anyone has a cam chart for a type F controller with a layout similar to this, please post it if you can.

Thank you all for your past and future help and advice!!!

Ideally, you would want to indeed start with Main Street first. The "0" mark (and dial key number one) on the dial timer begins a new cycle. The cam chart tells you how the cams are exactly configured, so it would be necessary to depict how they're configured on the chart (in order).

In your signal controller's cam assembly, you have enough circuits for both the Main and Cross streets. You have an additional three (with cam fingers and cams) that you could use for a third phase. Red, amber, and green. Just make sure they correspond to their correct terminal connections on the backpanel. I am fairly sure the connections for a third phase could be connected to the "S" terminal strip on the backpanel.

You mentioned 14 cams, you need 6 (R/Y/G/DW/FDW/WK) per phase for a total of 12 for main and side streets. Adding another phase later means you will need to re-cut the cams of the original phases. It implies also that you have 15 circuits available.

Addendum: I think Sean (Econo101) makes a plain old flasher, you need two.

I only have 14 circuits available, I used the cam chart that you posted to make my own to match the back panel on my controller. It is set up RYG instead of GYR like your sample chart.

Please check my work below:


I will have 2 circuits remaining to do???????? Can these two circuits be used for a protected left turn on "main street"??

I ordered a couple simple flasher kits, made by "Future Kit" they should be here today. I have to put them together, hope they work ok.....we'll see.

Thanks again!!!!
