as a result is not able to release the enabling control device. For this reason,
firmly pushing down on the enabling control device also leads to switch off.
The controller must be designed in such a way that machine movement is not
initiated directly when the enabling control device is activated but only as a
result of the additional activation of a control button. This may be via the hand-
held terminal’s membrane keyboard or graphical software buttons on the touch
screen.
An optionally available joystick can also be used to trigger the machine move-
ment signal.
According to EN 60204, only stop categories 0 or 1 are allowed for the enabling
function, i.e. stopping the machine with the enabling control device must al-
ways be combined with switching off the power supply to the drive mecha-
nisms.
In order to prevent incorrect, permanent activation of the enabling control de-
vice by mechanical fixing devices, it is recommended to limit the maximum
duration of an accepted enablement. This must be achieved by means of a
controller located downstream to the handheld terminal.
An enabling control device is not a replacement for a two-hand control device,
which is specified for some machines (e.g. presses) and must therefore not be
confused.
In contrast to the enabling control device, the two-hand control device forces
the endangered limbs of the operator into a safe position whilst the machine
is in motion.
