2.2.2.1 Enabling control device with 2 enable switches
The Mobile Panel with two enable switches is equipped with internal evaluation electronics.
The enabling electronics filter out possible asynchronous output signals of the two-channel mechanical switching
elements of the enabling device. As a result, both outputs of the enabling device are always synchronous.
If two enable switches are equipped, they are connected in parallel and have a similar effect on the overall safety
circuits in the attachment cable. For the enabling function, it is sufficient to press one of the two buttons. Pressing
both buttons simultaneously for more than 2 seconds causes the enabling signal on the output to be canceled when
one of the two buttons is released. The enabling electronics also allow changing grip (left ↔ right) between the
enable switches without switching off the signal on the output. It is important to ensure that both enable switches
are not pressed simultaneously for more than 2 seconds in order to allow changing grip.
2.2.2.2 Functionality
The actuating element is composed of a rocker switch whose position is determined by electrical switches and
passed on to the evaluation electronics.
The enable switch can have three different switch positions:
Switch position

1
Zero position
Not actuated
Off (opened)
2
Enable
Actuated
On (closed)
3
Panic
Fully actuated
Off (opened)
Table 5: Enable switch positions
Positions "Zero" and "Panic" must trigger a category 0 or 1 stop command.
Enable
Position "Enable" is the normal operating mode for the enable switch. In this position, it is possible to initiate an
axis movement by subsequently pressing a direction key, for example.
When actuated, the enable switch moves from position "Zero" to position "Enable". When released, it returns to
position "Zero".

Panic
If the enable switch is fully actuated (position "Enable" to position "Panic") and released, then the switch will return
to position "Zero" by skipping over position "Enable".
