The following graph shows the voltage on channel U0 of the spare crate while ramping using the OFF/STANDBY/PHYSICS logic described earlier.  The ramping values used are described below. 

Voltage step: 1000

Standby Voltage: 2000

Physics Voltage: 3600

Slow Ramp Rate: 10 V/s

Fast Ramp Rate: 60 V/s

Ramp Delay: 60 s

The following show the system response to the control buttons at various points in the ramping process:
