The enabling button has three switch settings:
● Neutral position
The enabling button is not pressed.
● Enable
The enabling button is pressed to a middle switch position. The switch position has a
noticeable pressure point. This switch position is used to confirm an entry, for example.
● Panic
The "Panic" switch position is reached as soon as one of the two enabling buttons is fully
pressed. To do this, the pressure point of the "Enable" switching position must be
overcome. An audible switching noise is then heard.
The switch position of the other enabling button is unimportant in this case. The "Panic"
switch position has the same effect as releasing the enabling button. In both switch
positions, the enable is revoked.
Requirement
● The enabling button is evaluated under the condition that the HMI device is integrated in
the safety program of the F-CPU. See section "Safety-related configuration (Page 161)".
Procedure
WARNING
Press the enabling button only as long as necessary
Enabling is a conscious operator action. It is not permitted to continuously press the
enabling button or to fasten it in place.
Press the enabling button only until the operation you wish to enable is completed.
Note
The enabling button only has an effect when the HMI device is logged on to a machine and
the "RNG" LED on the HMI device is lit.
Proceed as follows:
1. Press at least one of the enabling button to reach the "Enable" position.
The controller receives the same signal, regardless of whether one or both enabling
buttons have been pressed.
NOTICE
Enabling button can tilt
If you do not press the center of the enabling button, the enabling button may tilt. The
switching process is delayed by this. A discrepancy error may occur – see section
"Discrepancy error during enabling (Page 258)".
Press the enabling button in the middle.
