It is recommended to ramp up engine RPM to ensure sufficient hydraulic flow for
valves to operate. Possibly for vehicles with bigger pumps there is enough hydraulic
flow at idle RPM.

The Display screen is blank:
If the power switch light is not illuminated then:
• Possible sensor or solenoid short circuit
• Possible extender cable short circuit
• Unplug peripheral sensors and solenoids until problem goes away
• Replace defective sensor/solenoid
There is a time delay breaker in the knob console that may take a few seconds to
trip upon a fault condition. This will cause the display to blank. The breaker will
reset when the fault is corrected.
Some severe short circuits or circuit misuse can cause damage to the knob console.
If the power switch remains illuminated then:
• Unplug peripheral cables on the back of the display (i.e. temp sensor, GPS,
digital input cable)
• Check/replace the short interconnect between the display and the knob console
• If problem persists, the console may require service form the factory
