16.11 Staging Signal Function (SS)

This function uses an output to indicate when the engine is in the staging section of map, i.e..

when the load has increased beyond the Staging Load Bar set in the Fuel Set-up page. If

enabled, this sign al will op erate regardless of whether the ECU is running in Staged Injector

Mode.

Note: The staging signal does not pulse with the other injectors. It switches on

and stays activated while the load is above the staging point.

There are no programmable parameters associated with this function.

16.12 Turbo Timer (TT)

Care should be taken to make sure the relays are wired correctly, and that an over-ride switch

has been fitted to allow the engine to be switched off manually while the turbo timer is active.

See figure 16.13 for the correct way to wire this output. The ECU detects if the ignition

switch has been turned off v ia the Auxiliary Inp ut. Therefore, the Auxiliary Inp ut Function

must be selected as Turbo Timer in the Input/Output Set-up page.

There are three programmable p arameters. The first two are the minimum Air Temp . and the

minimum Coolant Temp . If the inlet air and the coolant temp eratures drop below their

respective values, the outp ut will switch off. The last p arameter is the Run Time. This is the

maximum time the ECU will allow the engine to continue to run after the ignition switch has

been turned off. If either of the temperature conditions are meet before this time, the output

(and therefore, the engine) will switch off. The Run Time is set to the nearest half minute.

Note: When using the Turbo Timer function, the Aux. In Function in the

Input/Output Set-up page must be set for Turbo Timer. When using TT, other

functions that use the Aux. Input line cannot be used.
