Another EPIC140 owner! I was an only soul up until recently. My EPIC had issues electronically which me and another member finally got working last year. I haven't had much recent experience with EPICs but I still know my way around them. I have the manual lying around.

Remember if yours has the EF-140 connectors it is not NEMA certified. There was a NEMA version made but I have yet to see one in real life.

Yes I can use the EF-140 controller and have many of these laying around but only one EPIC.. My cabinet was only 2 yrs old when I obtained it but had to buy the epic controller. the ole epic works great still...(fingers crossed) :good:

EPIC was the primary controller used in Michigan for years. EPAC seen limited use for actuated or more complex control. The trend is going to EPAC and other powerful controllers because the intersections are getting much more complex now with detection, etc. Its neat that all the official MDOT timing sheets have a checkbox for controller used...EPIC/EF140, EPAC, or "Other" :crazy:

The processor and/or powersupply kicked the bucket in mine.

The EPIC's with EF140 connectors (one small, one large) are not NEMA interchangable, because they don't follow the NEMA "A" "B" "C" protocol. Eagle made a version of the EPIC with "A" and "B" NEMA connectors that did follow protocol. Another member and myself rigged up EPIC firmware to run inside an EPAC300 controller and to my surprise the EPIC pinouts matched up, even though the I/O circuit board wasn't exactly the same.
