Joey,
Thanks. If using the C15R1WD and the pump is wired as depicted here
http://cnc4pc.com/Tech_Docs/C15R1WD.pdf (heavy/darker line is Line and lighter Neutral)
Then it shouldn't have the problem as described. If the pump's hot or Line is instead connected to NC (pos 1), then the wires need to be swapped and the HAL output reconfigured.
PS, Personally I wouldn't wire as they depicted, but rather as the terminal notation suggests. Run L to V-in (Pos 2) and the pump's hot leg to NO (Pos 3). This would allow you to use the other contacts (NC/PO 1) for alternate indication or use (what?.. be creative).
PSS, Rereading upthread, I realize I just said what MrWild had said earlier. Not bad for WAG, and apology for sounding like I was disagreeing. Was focused on the aforementioned HAL mode regardng pin 1. Hope to hear from SpeedCustom, to confirm how wild for MrWild.
