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 signal will operate regardless of whether the ECU is running in Staged Injector
M ode.
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 via the Auxiliary Input. Therefore, the Auxiliary Input Function
must be selected as Turbo Timer in the Input/Output Set-up page.
There are three programmable parameters. The first two are the minimum Air Temp. and the
minimum Coolant Temp. If the inlet air and the coolant temperatures drop below their
respective values, the output will switch off. The last parameter 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.
Figure 16.13 – Example of a Turbo Timer circuit.
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.
