Setup
For the Futaba SBUS2 system a variety of settings in VSpeak ECU converter using the
Programming a JetCat GSU can be made.
In the overview the complete menu structure for all possible range of settings is shown.
The navigation takes place in the usual way, ie "scroll" between the parameters with the +/-
buttons - Value change with the pushed "Change Value / Item" button and added +/- buttons,
then instead of the ":" a small arrow shows the changed values.
Here the sensor start ID can be set, which is used to
register the sensor on the Futaba system. In the case of
multi-trubine models, different values must be set here.
Here, the StartSlot can also be set manually: in the
transmitter, the " JetCat V10" sensor is also to be set
manually at the corresponding slot address (1…14).

Alarms
In the Futaba system alarms can be generated according to the set alarm thresholds for each
value in the transmitter. In the sensors itself no alarms can be set. This is for most sensor data
also sufficient, such as an alarm for monitoring the EGT temperature.
But for alerting the speed monitoring the VSpeak ECU converter for Futaba offers the following
option:
Rotation speed monitoring
(s. section 2.0)
Thus, the speed is displayed correctly, you have to set the speed display to type: magnet
and gear ratio 1.
RPM
Value range:
OFF, 20.000 ….99.900 rpm
Step size: 100 rpm
RPM2
Value range:
OFF, 1.000 ….99.900 rpm
Step size: 100 rpm
1. Setting value = OFF
The current speed is transfer 1 : 1.
If an alert threshold of for example <35,000 rpm is programmed in the transmitter, then the
alarm is already active at the switching on of the turbine and the receiving system. That's
why:
2. Setting value = 35.000rpm (als Beispiel)
The speed is transferred to the transmitter divided by a factor of 10. Only in the alarm case,
speeds less than the setting value are transferred 1 : 1. The alarm is active AFTER exceeding
the set value.
In the example, the speed monitoring is only activated after exceeding 35,000 rpm. The
actual 40.000rpm are displayed on the transmitter as 4.000rpm, 35,100 as 3.510rpm. If speed
decreases further then 35.000rpm speed transfer is 1 : 1. Has the transmitter an alarm
threshold set to > 15.000rpm, the alarm starts. If turbine speed falls below 15.000rpm - for
example, turbine was switched off, then the alarm stops because speed is now less than the
alarm threshold value.
