Line 97: − − Install a 3 phase 240v outlet near the machine. This machine is currently sharing one outlet with 4 other machines. − − The Handwheel uses a Heidenhain HR 150.001 5000 F4 controller, Id.Nr. 220 954 01, S.Nr. 1300302 A. It is very fragile, using a glass encoder wheel. We have determined that the light bulb that illuminates the wheel, triggering a signal from the photocells, has burned out. This will either need replacement, or we will need a new encoder. Ryan contacted Heidenhain, who does not repair this, and said "this was a very particular lamp/lens assembly, with the lamp focused through the lens in a particular way – not exactly a flashlight bulb." Heidenhain has a replacement: "ID. Nr. 540940-07. It is the current version of the HR 150. List Price $594.00" At Dean's request, Ryan shipped the encoder to Oracle Encoder Service on 5/6/15 for repair; quote was $290. This repair was completed. Oracle adjusted it with very low friction on the bearing, so the hand wheel wouldn't stay in place. Ryan sent this back to them, they fixed it to increase the friction, and it now works. Ryan re-installed it.

Spindle RPM adjuster controls are reversed. Decreasing spindle speed barely functions and needs more work to obtain satisfactory performance.
Make aluminum spoil plates and clamps to minimize risks of table mounted work.
Check the BP maintenance manual for other adjustments that are required.

The machine was wired at the factory for 460 volt 3 phase and we use 230 volt 3 phase in our shop. Ed and Dean rewired the motor and controller box, in a temporary fashion, to use 230v. It had been using a 460 to 230 volt transformer. Ryan removed this 6/26/2015 and changed all three transformers to use 230V, and re-enabled the accessory outlets at the rear of the machine. He also moved the Heidenhain power source back to the Bridgeport control. PS:One has voltage approaching 250V, so in some cases the voltages at transformer taps are a bit high. However the Heidenhain power, and the external 120V outlets, appear pretty much spot on.
