TSLM - M601 Operational & Install Manual
Parameter Exceeds
Should any of the engine parameters go over their maximum limits the EXCEED light (if installed)
will come ON for the duration of the exceed. During this time all relevant parameters gets recorded
versus time and a dedicated counter increments within the TSLM. This information can be viewed
in the Configuration and History sections of the
SetView
software.
Parameter exceeds (maximum values) are according to the type of M601 engine used:
Engine Type
Max. ITT
Max. N1
Max. N2
Max. Torque
M601D
735 °C
100.00%
2080 RPM
132 psi
M601E-11
735 °C
100.00%
2080 RPM
145 psi (106%)
M601E-11A
710 °C
98.50%
1950 RPM
134 psi (98%)
Make sure that you set the “Engine Type” configuration property to the appropriate model engine
you are using (see page 28).
Required Actions
Should the EXCEED light have come on during flight, you can retrieve and analyze the time-graph
recorded within the TSLM to decide on what action to take next. Required actions vary from no
action to returning the engine to an overhaul facility for inspection/repair. With the graph you will
not only identify the parameter exceeded, but obtain both the maximum it reached as well as the
time it spent above the maximum limit. With this you will be able to look-up the required action you
need to take using the engine's manual, or asking a qualified person.
TSLM Light Codes
The TSLM light provides feedback to the pilot concerning the system. The light will blink a certain
pattern to report any problem to the pilot. The following table shows the codes:
Problem
TSLM light indication
ITT Error
2 blinks.. pause.. 2 blinks.. pause, etc
Voltage Error
3 blinks.. pause.. 3 blinks.. pause, etc
EHT Error
4 blinks.. pause.. 4 blinks.. pause, etc
N1 Error
5 blinks.. pause.. 5 blinks.. pause, etc
ISOL Error
6 blinks.. pause.. 6 blinks.. pause, etc
Memory Warning
7 blinks.. pause.. 7 blinks.. pause, etc
TSLM Internal Error
Solid ON, or slowly flashing
See also the sections that describes initiating a start and a run.
Acknowledging the TSLM light Indication:
An error code can be acknowledged and reset by holding either the start or run button / switch
down for at least 1 second. The TSLM light will then stop blinking, which will indicate that the TSLM
is now ready to accept new commands from the pilot (start, run, etc.).
