KEYENCE GL-RHG Series - Manual (Page 8)

8 E GL-RHG-IM
*1 When the GL-RHG is used under surrounding air temperatures between 50 to 55°C, the Maximum
load current should not exceed 350 mA.
*2 For PFHd of each GL-RHG, contact your nearest KEYENCE office.
 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.
• 2.0 m/s is the maximum object detection speed of the GL-RHG series.

Troubleshooting
If the GL-RHG is not functioning normally, check the GL-RHG indicators first.
The GL-RHG is in an error condition under the following situations.
•
The center indicators blink in red.
• The 7-segment display indicates "".
If the GL-RHG does not demonstrate the above situations, the GL-RHG is not in an error condition.
 If the GL-RHG is in an error condition
