Response time (OSSD)
Units: ms
*1 If the interruption is present in the protective 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.
*2 "All blocked" means the situation where the GL-RHG 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-RHG synchronizes the transmitter and receiver
first and then determines the clear or blocked.
Point
• If the response time (ON to OFF) exceeds 20 ms, this unit cannot be used as a certified
product based on the Chinese standard GB 4584 "压力机用光电保护装置技术条件".
• When the GL-RHG units are connected in series, the response time is calculated according
to the following steps;
1. Sum up the response time of all unit.
2. Subtract the following time from the result of previous step.

ON to OFF
One sub unit : 2 ms
Two sub unit : 4.2 ms
(When Optical synchronization system and Channel A or B)
One sub unit : 2.7 ms
Two sub unit : 5.7 ms
 OFF to ON
One sub unit : 42 ms
Two sub unit : 84 ms
When connecting the GL-R32HG (32 beam axes), GL-R24HG (24 beam axes), and GL-R12HG
(12 beam axes) in series for one-line system, the response time of each unit is 7.9 ms, 7.0
ms, and 6.6 ms respectively, and the response time (ON to OFF) is 7.9 ms + 7.0 ms + 6.6 ms
- 4.2 ms = 17.3 ms.
the response time (OFF to ON) is 50.6 ms + 49.3 ms + 48.7 ms – 84 ms = 64.6 ms.
"Series connection" (page 2-3)
• 2.0 m/s is the maximum object detection speed of the GL-RHG series.
