Engine Speed Limit

Engine speed limit applied when limit is active

Control Range (-/+)

Engine Speed Limit control range in RPM when limit is active

Minimum %Cut Clamp

Percentage cut applied to the engine at the start of the control range.

The cut type is defined in the Function Output.

Maximum %Cut Clamp

Percentage cut applied to the engine at the end of the control range 

The cut type is defined in the Function Output

Limit Hysteresis

Oil Pressure must return to the (Limit Value + Hysteresis value) for the “Recovery Hold Time” entered before the Limit is switched OFF.

Post Start Lockout

Will prevent the limit operating during crank and for a time after the engine has started.

Limit Recovery Mode

Controls the limit exit strategy.

Mode 0: Oil Pressure > (Target Limit Pressure + Hysteresis) for the specified Hold Time.

Mode 1: Oil Pressure > (Target Limit Pressure + Hysteresis) for the specified Hold Time.

AND      Engine Speed must have reached the value in the Engine Speed Limit setting

0: Mode 0

1: Mode 1

Limit Recovery Hold Time

When the Engine Protection limit is activated a time delay can be applied before the engine can recover.  

This to prevent premature engine recovery from an Engine Protection event.

Limit Recovery Cut Time

Allow the cut to be progressively removed from the engine.

User Lockout

Allows the user to Lockout the Limit.

When the selected User Channel is ON a Limit request will still be generated but the engine will not be limited. ie %Cut will be zero.

Used for situations when you want to generate a Limit Request but not actually limit/cut the engine.

Example: During a Launch the Oil Pressure may temporally drop below the Limit Target. 

                A User Channel can be configured to lockout this limit during the first stages of Launch Control.

0: OFF

1: User Channel 1

2: User Channel 2

3: User Channel 3

4: User Channel 4

5: User Channel 5

6: User Channel 6

7: User Channel 7

8: User Channel 8

9: User Channel 9

10: User Channel 10
