Emergency stop button
The built-in emergency stop button is providing an emergency stop function for stopping
hazardous functions and removing power to them.
The emergency stop button has two forcibly-guided normally closed contacts.
Note on safe actuation!
To allow for the emergency stop button to operate safely, we recommend to use and assembly our holders,
designed especially for this enabling device.
Detailed description of this is to be found in the accessories section.
Attention!
Particular caution should be exercised in relation to enabling devices that are connected, as standard, using
a connector. Be aware of the following items:
•
The correct function of the emergency stop must be check monthly!
•
The emergency stop function must always be available and functional, and should have priority over all
other functions and operations in all operating modes of the machine without affecting any facilities
which are designed to release trapped persons.
•
No start command (whether intentional, unintentional or unexpected) should be able to affect working
processes that were stopped by initiating the emergency stop function until the emergency stop
function has been reset manually.
•
If it is possible to remove emergency stop buttons (e.g. portable programming devices) or shut down
sections of a machine, it must be ensured that operational and non-operational emergency stop
buttons are not mixed up.

Attention!
The controls for the feedback LED are independent from the emergency stop button function.
The programmer is solely responsible for their signaling function.
ABB JOKAB SAFETY does not accept any liability for damages of any kind caused by signaling that is not
logical, and the resulting misjudgments and errors by users.
