Troubleshooting - ROBBE SZD 54 Manuel D'utilisation

3. Using the ESC
IMPORTANT! Due to different throttle ranges with different remote controls please cali-
brate the throttle range before the first flight!
Throttle adjustment:
(The gas range should be reset each time the remote control is changed.)
1. Switch on the radio with throttle stick up (full).
2. Connect flight battery and wait for approx. 2 sec.
3. A „beep" sound should be heard, this confirms the setting of the full throttle position.
4. Put the throttle stick to lowest position, more „beep" sound should be heard, which-
show the number of cells
5. A long „beep" sound should be heard which confirms the lowest throttle stick positi-
on.
Normal Start-Up procedure
1. Throttle stick to lowest position, switch on radio.
2. Connect battery to ESC. Special tone as "♪123" means the voltage input is ok.
3. More "beep-" tones should be heard to show the number of cells.
4. A long „beep" tone sounds after self-test.
5. Move the throttle stick upwards to increase the power.
Safety functions
1. Startup Fault protection: If the motor is not started within 2 seconds after throttle mo-
vement starts, the controller switches off the throttle function. In this case the throttle
MUST be reset to the lowest position. (Such a situation occurs as follows: The connec-
tion between governor and engine is not stable, the propeller or engine is blocked,
the gearbox is damaged, etc. (The throttle is in the lowest position).
2. Overheat protection: If the temperature of the controller rises above 110°C, the con-
troller reduces the output power.
3. Lost of transmitter signal: The controller reduces the output power if the transmitter
signal fails for 1 second, further loss for 2 seconds causes the output power to be
switched off.
