10. REGULATOR ERROR MESSAGE
The PowerBox Cockpit, Competition and Professional constantly checks
both voltage regulators independently of each other. If a fault should occur in
one of these regulators, this warning will appear on the screen:
There are three possible causes for this warning:
- One or both regulators is generating insufcient output voltage or none at all.
This could mean that you are ying with only one regulator functioning, and
for reasons of safety this is not permissible.
- One or both regulators is not functioning, and is passing through the full
battery voltage. This means that the servos and receiver are being operated
on an excessive voltage, which could lead to failures in the longer term. This
malfunction usually occurs after a reversed polarity connection.
- One battery is plugged in but not switched on. The second battery is plugged
in and switched on. The screen displays the message REGULATOR MAL-
FUNCTION. This does not indicate a fault! The message is a warning, and is
intended to remind the user to switch on both regulator circuits.
In the rst two cases please send the device to our Service Department at
the address below, with the completed repair form which you can download
