The configuration of and components used in any circuit other than an appropriately pre approved
safety module that interfaces with the WJ200 GS1/GS2 and EDM ports MUST be at least equivalent
to CAT 3 PLd under ISO 13849-1:2006 in order to be able to claim an overall CAT 3 PLd for the
WJ200 and external circuit combination.

Periodical check (proof test)
Proof test is essential to be able to reveal any dangerous undetected failures after a period of time, in
this case 1 year. Carrying out this proof test at least one a year is the condition to comply the
ISO13849-1 PLd.

Precautions
1. To assure, that the Safe Disable function appropriately fulfills the safety requirements
of the application, a throughout risk assessment for the whole safety system has to be
carried out.
carried out.
2. The Safe Disable function does not cut the power supply to the drive and does not
provide electrical isolation. Before any installation or maintenance work is done, the
drives power supply must be switched off and place a tag/lock-out.
drives power supply must be switched off and place a tag/lock-out.
3. The wiring distance for the Safe Disable inputs should be shorter than 30 m.
4. The time from opening the Safe Disable input until the drive output is switched off is
less than 10 ms.
