6.4 Protection against unintended movements from the rest position
Unintended movements of the Machine, that is Machine movements that are
not activated by movements of the actuators, may occur due to electrical or
mechanical failure or malfunction that may aect the Radio Remote Control.
The Autec Radio Remote Control includes a function that seeks to protect the Machine
from such unintended movements by electronically checking the rest position of actuators
in the Radio Remote Control. The rest position of the actuators on the Transmitting Unit is
the neutral position. When the actuators are in such neutral position, no command from the
Transmitting Unit directing a Machine movement is being sent.
Each time one of the actuators is moved, the Transmitting Unit sends both the movement
command and the “SAFETY” command through this function. This feature is designed to
check whether the actuator is in fact out of the neutral position: if the Radio Remote Control
detects that the actuator is in the neutral position, it ignores the command.
UNINTENDED MOVEMENT MAY RESULT IN SEVERE INJURY OR DEATH,
OR PROPERTY DAMAGE. FAILURE TO INSTALL AND WIRE THE SAFETY
RELAY CONTACTS ON THE RECEIVING UNIT CORRECTLY WILL CAUSE
THIS FEATURE TO NOT OPERATE CORRECTLY AND WILL INCREASE THE
RISK AND OPPORTUNITY FOR UNINTENDED MOVEMENT.
MOVEMENT OF THE MACHINE WILL OCCUR WHENEVER THE ACTUATOR
IS MOVED FROM ITS NEUTRAL (CENTRAL REST) POSITION ON THE
TRANSMITTING UNIT . THIS RADIO REMOTE CONTROL WILL NOT DETECT
WHETHER THAT MOVEMENT OF THE ACTUATOR WAS INTENTIONAL OR
ACCIDENTAL. INADVERTENT ACTIVATION OF COMMANDS WILL ALSO
CAUSE MOVEMENT OF THE MACHINE (SEE PARAGRAPH 7.3).
THE FUNCTION DESCRIBED IN THIS PARAGRAPH IS NOT A SUBSTITUTE
WHATSOEVER FOR THE PROPER OPERATION, PROTECTION AND USE
OF THE TRANSMITTING UNIT IN ACCORDANCE WITH THE INSTRUCTIONS
CONTAINED IN THIS MANUAL (INCLUDING ALL OF ITS PARTS); THE USER
MUST AT ALL TIMES PAY FULL ATTENTION TO THE SAFE AND PROPER
OPERATION OF THE MACHINE IN ACCORDANCE WITH THE INSTRUCTIONS
AND WARNINGS PROVIDED IN THIS MANUAL AND IN THE MANUAL FOR
THE MACHINE AND WITH ALL APPLICABLE LAWS AND STANDARDS,
EVEN LOCAL.
