There are three conditions used to arm the Overrun Boost System.


Before the Arming Conditions are evaluated the Engine Temperature MUST be less than  "Maximum ET" setting and EGT1 and/or EGT2 less than the "Maximum EGT" setting.  


Arming Condition 1. When the Engine Speed exceeds the RPM Arming threshold AND the Anti-Lag Arming switch in ON.

OR

Arming Condition 2. When the Throttle Position 1 exceeds the TPS1 Arming threshold AND the Anti-Lag Arming switch in ON.

OR

Arming Condition 3. When the User Channel (if selected) is ON AND the Anti-Lag Arming switch in ON.



NOTE: The Anti-Lag Arming Switch ONLY gets checked/used if an Input Source Channel has been selected.
