We need to install a Quantum FRA Event Recorder on our ALCO (RSD-15). The Quantum unit is designed for EMD. Does anyone have any experience with this installation that might be willing to give me some advice?
I have 2 specific areas of concern, both electrical:
1) Axle speed: Our RSD-15 has a GE axle alternator that drives the transition control logic. The Quantum unit expects a 20 (or 60) pulse/revolution encoder. I think that means we need to mount another axle encoder, but I could really use some suggestions.
2) Throttle position: The Quantum unit is designed to interface to a Woodward governor. It has 4 wires that record the status of the A/B/C/D valve on the Woodward governor & then internally converts that to the throttle position. We have a GE 17MG8 governor. It has 4 "Engine Speed Relays" that control the governor. I'm not sure if there is a way to properly connect these.
Any suggestions are greatly appreciated!
