9. ZERO SPEED SHUT-OFF
This function will be active when C-FC (Fast Close Valve) or C-PC (PWM Close Valve) is selected.
This function can not be disabled. When C-FC or C-PC has been selected, the valve will receive
a decrease signal and run closed when the speed drops to .7 MPH or less. The only way the console
can operate at .7 MPH or less is in the manual mode.
When a zero speed shut-off has occured, the MASTER switch must be turned OFF and then ON
to restart the system. If a constant speed greater than .7 MPH is not attained within 10 seconds,
the zero speed shut-off will be enacted again.
