Ha! First post! Sorry for the delay but I've been waiting to get my account turned on.
Here's what you need to add the 'factory' coolant wiring:
- There's a two-terminal circuit breaker that plugs into the power distribution board (you probably already have other breakers and fuses in the vicinity). The location for the coolant breaker is clearly labled. You need that one. Your HFO should have them in various amp ratings. Mine gave me a used one and it worked fine.
- There is a factory harness that goes from the power distribution board down to the I/O board (lower-left corner of the cabinet). Both ends are clearly marked and if you buy the harness from the factory, it has the terminal numbers identified on it (no brainer).
- From the I/O board, it's one more connection from the I/O board to the 230V outlet (two hot, one ground). Again, this is part of the harness and it's plug & play.
This kit is supplied as part of a coolant installation kit (when a customer orders a full coolant system after the sale). Because many machines came wired from the factory with this already in place, the techs often have leftover wiring kits. Mine said he had a bunch of them.
If you're really nice to the guys at your HFO, you might be able to get a leftover kit 'cheaply'
. They included mine in with the purchase of my TL-1 so all I needed was a tank, pump, etc. I got incredibly lucky and found a 'used once' TL-1 coolant tank and pump on eBay the same week that my machine arrived. Yeah, I get lucky like that sometimes.
Even if you can't get it cheaply, that's the wiring you need. With the right connectors, installation is painless. Without them, I don't know how you'd get the right connectors for the boards. You could always use the M-code relays in the cabinet but they won't work with the Coolant buttons on the control (not as convenient).
