Safety Instructions For Operation - DEMAG DRC-10 Operating Instructions Manual

2.6 Safety instructions
when first putting the
unit into service after
completing installation
2.7 Safety instructions for
operation
• The working area must be made safe.
• First check that the voltage and frequency specified on the type plates match
the owner's mains power supply.
• In the course of putting the product into service, it may be necessary to render
safety devices or features inoperative when carrying out adjustments or function
checks.
• When putting the unit into service, it may be necessary to perform work in the
danger zone, therefore, it must be ensured that only appropriately trained per-
sonnel are employed for this work.
Before putting the crane into operation, the operating personnel must be satisfied
that the radio control system is in safe and correct operating condition.
In addition, the safety instructions and measures contained in the operating in-
structions of the crane must be applied.
The clear assignment between the DRC-10 hand-held transmitter to the radio
receiver (DRC-DR/DRC-MP) on the crane is the precondition for safe wireless
remote control of a crane. This unique assignment is created by the exchange of
the address features between transmitter and receiver when a DRC-10 hand-held
transmitter is put into operation. The operating personnel recognises which crane
is controlled by means of the crane identification shown in the display of the hand-
held transmitter.
Before switching on/putting into operation of the crane/machine controlled by the
radio control system with the DRC-10 hand-held transmitter, it must be ensured
that nobody is endangered by operation of this crane.
If the operator notices persons who may be exposed to a risk to health or personal
safety by operation of the equipment, he must suspend operation immediately and
may not resume operation again until the persons are outside the danger zone.
STOP key function
Actuation of the red STOP key activates the emergency-stop function in the radio
receiver on the crane. The emergency-stop function stops any potentially danger-
ous movement of the crane. For use of the emergency-stop function, in particu-
lar the instructions contained in the operating instructions of the crane must be
complied with. When the STOP key has been actuated, the radio system is in the
"STOP" operating mode. No movement commands are transmitted. The emer-
gency-stop can be unlocked again by entering an electronic key. This may only be
done after the operator has made sure that the hazardous situation which resulted
in actuation of the STOP key has been eliminated.
Warning device function
Radio-controlled cranes must be provided with a warning device (acoustic or opti-
cal). The crane operator can activate this warning device by means of the signal
key in the keyboard of the hand-held transmitter to warn persons in the vicinity of
the crane and/or load before starting the crane movements. The warning device
must also be used if the crane operator intends to check the assignment between
the hand-held transmitter and the crane receiver by means of a hand-held trans-
mitter command.
Range of the radio remote control system
The crane operator may only use the range of the radio control system to the
extent that he can freely monitor the danger zone of the crane movements.
The range of the hand-held radio transmitter is limited and can be additionally
reduced by ambient conditions. The range may also be limited by utilization of
the available frequency range by other radio transmitters. The quality of the radio
signal is shown in the display of the hand-held transmitter. If poor connection
quality is displayed, unintended interruptions of the controlled movements may
occur.
