4.8.2 Types of managed restart
NOTICE: it is the responsibility of the machinery manufacturer to assess if automatic restart prevention can
guarantee the same level of safety as manual restart (as defined in standard EN ISO 13849-1:2015, section
5.2.2).
For each detection field independently, the system manages three types of restart prevention:
Type
Automatic The time interval set through the Inxpect Safety application
(Restart timeout) has passed since the last motion detection*.
Manual The Restart signal was received correctly** (see "Restart signal"
on page 97).

2. the status of the restart signal indicates that the restart is
Note *: machinery restart is enabled if no motion is detected up to 35 cm (13.8 in) beyond the detection field.
Note **: (for all types of restart) other dangerous system statuses may prevent the restart of the machinery (e.g.
diagnostic fault, sensor masking, etc.)
4.8.3 Precautions for preventing unexpected restarting
To prevent unexpected restarting, if the sensor is installed at a height of less than 30 cm (11.8 in) from the
ground, a minimum distance of 50 cm (20 in) from the sensor must be guaranteed.
Note: if the sensor is installed at a height of less than 30 cm (11.8 in) from the ground, an option is to enable the
masking function to generate a system error if a person stands in front of the sensor.
