GRAUPNER G-BOOSTER 160 – Manual 1.91
1:INFO – Operating Status Information
10:R/C-FAILS
indicates the number of R/C failsafes (failures of the remote control connection) that lasted longer
than one second during the last engine run. Normally this parameter should be #0, i.e. no failsafes.
If the number is frequently greater than #0, you should check your remote control system.
Do a transmission range test!
11:EGT-AVERAGE
shows the average exhaust gas temperature during the last engine run. Typical values after a flight
should be between 450 and 550 °C. Higher values might be caused by an unsuitable exhaust duct
or insufficient ventilation to the turbine.
12:EGT-PEAK
shows the maximum exhaust gas temperature that occurred during the last engine run. This value
is normally reached only briefly during the acceleration of the turbine until the higher revolution
speed is reached. Typical values can be up to 750 °C.
13:FUELPMP-PEAK
shows the maximum fuel pump voltage during the last engine run. A ! after the "Volt" means
that the maximum allowed pump voltage specified under LIMITS 33:FUELPMP-MAX has been
reached. The maximum pump voltage is a good indicator for the quality (flow resistance) of the
entire fuel supply system. An continuously increasing pump voltage after the flights may be caused
by a plugged filter or fuel clunk.
14:RPM-PEAK
shows the maximum revolution speed of the turbine during the last engine run. Normally, this
value should match the full thrust rpm value specified under LIMITS 31:ENGINE-100%. A ! after
the "rpm" means that the 100 % thrust rpm value has not been reached. The reason may be a
cramped fuel tube or a plugged filter or fuel clunk. It is also possible that the maximum fuel pump
voltage specified under LIMITS 33:FUELPMP-MAX is too low.
15:AIRSPEED-PEAK
shows the maximum airspeed during the last flight. This requires an airspeed sensor to be installed
and the parameter 58:AUX-MODE to be set to AIRSPEED.
16:AIR-DISTANCE
shows the distance covered during the last flight. This requires an airspeed sensor to be installed
and the parameter 58:AUX-MODE to be set to AIRSPEED.
17:ENGINE-TEMP
shows the current temperature under the turbine cover in °Celsius.
18:ECU-TEMP
shows the current temperature in the JETRONIC unit in °Celsius.
