Does anyone know if I can make my epic 140 traffic controller operate my 5 light doghouse!? Also How do I program it to operate a Michigan left turn arrow?? HELP!!

Depends on how you want to operate the doghouse config... Lead/Lag, etc.

Michigan standard left turn with flashing red was programmed as follows. EPIC did not follow NEMA phasing guidelines...meaning odds and evens didn't always relate to left turns and through movements respectively.

V1: Thru Main
V2 Left Main
V3 Thru Cross
V4: Left Cross

P1: Ped Main
P3: Ped Cross

VA: Right Arrow Main
VB: Right Arrow Cross

Here is the chart I drew up for the old standard sequence that was often programmed into EPIC 140 controllers:

Each row designates an interval that the controller times...under Signal Plan Data>> Interval Times from the main menu
Each column is the output status that is programmed in code under Signal Plan Data. This chart is for a full Michigan intersection with flashing red on all four approaches, peds, and a single section right turn arrow.

No problem. Let me know how it goes or if you need additional help. I am looking forward to seeing pictures!

Hey, the signal plan works great but the interval times are wwaaayyyy off! Green lights are way to short timed and yellow and red lights take forever to cycle! Is there a chance you have the cycle timing for this signal plan?

plus i just realized that i need two more load switches! I'll just take the crosswalks off for now though!

The interval times in signal plan data are minimum. Are you running coordination? I will check the manual to see how split times affect interval times

I have no idea actually, I have the manual for it but no idea how to coordinate anything :scratch:

First I would try with coordination off, go into Coord Data>> and select Free (0). Then go to the main menu and go to unit data>>Veh and Ped recalls and put the minimum recall in for all groups and peds. This should pull just from the min interval times, if I remember right. Sounds to me like the coordination interval times are overriding the minimum times. Let me know if you make progress, if not I have a few other options. It's been a while since I really played with an EPIC programming

i have the coord set to (0) already but i will try the second step tomorrow sometime, thanks again for helping me with this situation so much!
