When connecting high inductive loads to OSSDs, use suitable voltage suppressors on the outputs.
In free protected area conditions, the Active element provides a voltage of 24VDC on both outputs.
Therefore, the established load must be connected between both output terminals and the 0VDC.
AUTOMATIC OPERATION
In Automatic operating mode, the OSSD1 and OSSD2 safety outputs follow the status of the light curtain:
¾
with guarded area free, the outputs are ON.
¾
with guarded area occupied, the outputs are OFF.
If the SAFEGATE light curtain is used in AUTOMATIC mode, it will not be equipped with
a start/restart interlock circuit. In most applications, this safety function is mandatory.
Carefully evaluate the risks analysis of your own application.
TEST FUNCTION
The SAFEGATE barrier system features an automatic self-diagnosis function that enables it to detect
response time malfunctions (this time is declared for each model).
This fault detection system is always active and does not require any external intervention.
