TROUBLE SHOOTING
Introduction: Glossary
Passive Emergency Stop concept
In case of system failure, the radio control automatically gets into safe status mode. At the
receiver all outputs are de

energized and the STOP circuit opened The most common

all
outputs
are
de
-
energized
and
the
STOP
circuit

.
The
most
common
cause is an interruption of the radio transmission ( for >0,8s) because of:
• strong radio interferences: another radio control is being operated nearby at the same
frequency
• The action range has been exceeded or a metallic surface is present between the
transmitter and the receiver.

It can be performed by the operator entering a procedure directly from the transmitter. This
