Switch-off conditions
Make sure that the switch-off condition is sufficient!
The actuation period for safety mats and bumper must be at least twice as high as the maximum
value for the "test period" of both test outputs used in order to ensure that the switch-off condi-
tion will be detected and that a sequencing error will not occur.
NOTICE
You can find additional information in the operating instructions for the safety mats.

Test periods and response times
Changed reaction times!
From build state D 03.01 of the MSI 4xx modules and B 08 of the MSI-EM-IO84 modules, the
longer response times given in the table below apply.
In particular, for existing projects with sensor elements for safety mats and bumpers, this exten-
sion of the response times must be adhered to (e.g. in the case of replacement of a MSI 4xx
module).
