*2 If the interruption is present in the detection zone for less than 80 ms, the response time (OFF to ON) will be 80 ms or more to ensure that the OSSD maintains the OFF state for more than 80 ms.
*3 “All blocked” means the situation where the GL-R operates in optical synchronization system and the
transmitter and receiver is not synchronized (top and bottom beam axes are both blocked). In this situation,
the response time is longer because the GL-R synchronizes the transmitter and receiver fi rst and then
determines the clear or blocked.
