•
The terminals J1 and J2 were jumpered with the supply voltage switched on.
•
The supply voltage was interrupted during the teach-in process.
NOTE
■
Multiple teach-in of the same actuator at the same sensor is not possible.
■
The sensor can be operated only with the actuator that was last taught in.
■
The teach-in process is invalid if it is canceled before the green LED goes out or if
the voltage supply is switched off during the teach-in process.
7.3.4
Changing the configuration, teaching in new actuators
The evaluation unit can be reconfigured any number of times and faulty actuators can
be replaced. There is no limit to the number of teach-in processes.
The same procedure as for the first teach-in process must be followed in order to
change the configuration or teach in new actuators (
see "Preparations for teach-in",
).
7.4
Thorough check
Requirements for the thorough check during commissioning and in certain situations
The protective device and its application must be thoroughly checked in the following
situations:
•
Before commissioning
•
After changes to the configuration or the safety function
•
After changes to the mounting, the alignment, or the electrical connection
•
After exceptional events, such as after a manipulation has been detected, after
modification of the machine, or after replacing components
The thorough check ensures the following:
•
All relevant regulations are complied with and the protective device is active for all
of the machine’s operating modes.
•
The documentation corresponds to the state of the machine, including the protec‐
tive device
The thorough checks must be carried out by qualified safety personnel or specially qual‐
ified and authorized personnel and must be documented in a traceable manner.
b
Check whether the protective device of the machine is effective in all operating
modes in which the machine can be set.
b
Make sure that operating personnel have been instructed in the function of the
protective device before starting work on the machine. The machine operator has
overall responsibility for the instruction, which must be carried out by qualified per‐
sonnel.
