Operation
One hand device
To activate a one hand device, both buttons on the Safeball must be pressed. Unlike a two-hand device, there is no
time requirement for activation of the two buttons. Instead, the safety distance is longer. Refer to Installation
precautions above for further details. The safety monitor must send a "stop" signal as soon as one or more
pushbuttons have been released, and check that both pushbuttons have been released before a new start is
possible.
Two hand device
To activate a two-hand device, the two individual one-hand devices must be activated within 0.5 seconds of each
other. This must be set up in the safety monitor by the safety application programmer. The safety monitor must also
send a "stop" signal as soon as one or more pushbuttons have been released, and check that all pushbuttons have
been released before a new start is possible.
Limitations
A two-hand control system does not give any protection against parts or liquids which can be thrown out of a
machine. If it is required to protect other persons in the same risk area, either each person at risk should be
equipped with a further two-hand control system (suitably interlocked), or complementary protection should be
provided, e.g. a light curtain.
