Cart startup procedure:
1. Plug in the cart
2. Hit start (F1, circled in pic). This will turn on the roughing and turbo
- Open the gate valve on top of the turbo
- When turbo hits ~200Hz: Turn on the CCG
- Wait for turbo to settle at 1000Hz and 1A (info on display).
- If this happens, you’re DONE!
- If this does not happen, begin troubleshooting: checking pressure, looking for leaks.
- If issues persist, initiate cart shutdown:
- open the N2 cylinder and regulator
- confirm N2 is coming out of the cart’s PRV
- close the gate valve on top of turbo
- hit Stop (also F1). This stops the turbo + roughing, and automatically vents through the turbo.
- open the small N2 valve on left side of cart, this vents N2 above the closed gate valve.
- wait for vent to complete, confirm N2 is coming out of the cart’s PRV
- close the small N2 valve on left side of cart, close the N2 cylinder
