3.2 Application description
The Safe Linear Positioning safety system is designed for applications in which the safe
posit
ion monitoring of linear drive systems is required. Target applications are, for
example:
•
Skillet conveyors
•
Cranes
•
Storage and retrieval systems (SRS)
•
Gantry robots
•
Applications in which movable devices need to be positioned in relation to a refer‐
ence
The safety system fulfills the requirement of detecting the safe absolute position in the
case of linear drive systems. This makes it possible, for example, to safely delimit posi‐
tion ranges within which the maximum permitted speed is safely reduced so as to pro‐
tect people and materials.
The system can be used to determine the current movement status, including, e.g., the
position, speed, and acceleration at any point in time. If movement statuses cannot be
reliably detected or if there is a fault, the safety-related task of the safety system is to
switch the relevant parameterized outputs of the safety controller to the safe state.
If it is necessary to initiate and/or safely monitor a ramp or speed reduction at certain
positions, the safety system provides the corresponding safe position data alongside
the underlying safety functions for the machine. Additional safety functions can be
added to the safety system.
OLM100 Hi absolute displacement sensors (optical linear measurement sensors) from
SICK are used to monitor linear movements. These are opto-electronic sensors that can
measure product travel paths without moving parts. The sensors orientate themselves
using a bar code tape attached along the product travel path, using a visible, red LED
beam. By reading the bar code, the linear measurement sensors determine the
absolute position and deliver this via an interface. The Flexi Soft safety controller from
SICK, which also forms part of the safety system, uses appropriate diagnostics mea‐
sures to check whether the absolute positions of the OLM100 Hi sensors are plausible.
