5 Functioning principles
upright or squatting position.
The system sensitivity is higher than the sensitivity that characterizes the access detection function. For this
reason, the system reaction to vibrating and moving parts is different.
When the restart prevention function is active the monitored area may be affected by the
position and inclination of the sensors, as well as by their installation height and angular
coverage (see Sensor position on page 52).
5.4.4

Restart timeout parameter

When the system does not detect motion anymore or, with static object detection option enabled, no static
object is detected, the OSSD outputs remain in OFF-state for the time set in the Restart timeout
parameter.
The default value is 4 s, the maximum is 60 s, and the minimum is the CRT (Certified Restart timeout).
The static object detection option affects the value range of the Restart timeout parameter
and therefore affects the operation of the restart prevention function (see Restart timeout
parameter on page 44).
The parameter is valid only for the restart prevention function.

Safety working mode: Always-on access detection

5.5.1 Safety function: access detection
This is the only safety function available for the Always-on access detection. Access detection allows
what follows:
When...
no motion is detected in the detection field
motion is detected in the detection field
If the Always-on access detection is selected, additional safety measures must be
introduced to ensure the restart prevention function.
5.5.2 T parameter
OFF
If the safety working mode is Always-on access detection, when the system does not detect motion
anymore, the OSSD outputs remain in OFF-state for the time set in the T
The T value can be set from 0.1 s to 60 s.
