Ensuring proper GL-RHG installation near a glossy surface
If there is a glossy surface around the GL-RHG, the GL-RHG may be affected and may not detect an
interruption in the protective zone.
To avoid this problem, installation must be done according to the following:
When determining a specific installation distance, refer to the following values including the installation
tolerance.
Wiring
Point
•
Each model is connected to one cable. Therefore, at least two cables are needed as a
system, one for the transmitter and another for the receiver.
•
All cables can be used for both the transmitter and receiver.
•
The combination of the wiring system and cable determines the functions that can be
used. Different types of Cables can be used for the transmitter and receiver.
•
Be sure to match the numbers of conductors (core wires) when using the unit connection
cable for extension use and the extension cable.
Cable specification
(1) Cable length
1. Optical synchronization system, wire synchronization system
The sum of the length for the unit connection cable and extension cable must be 30 m or less.
This limitation applies separately to the entire transmitter cable setup and the entire receiver cable
setup.
2. One-line system
The sum of the length for all of the unit connection cables, extension cables and series cables
must be 30 m or less.
(2) Minimum cable bending radius : 5 mm
(3) Identification of connector cables
Connector colors
PNP output type cables or series connection cables : Black connectors
NPN output type cables
: Grey connectors
Point
PNP output type cables and NPN output type cables cannot be used at the same time
(mixed wiring is not possible). One type of cable must be chosen based on the application.
(4) When using as safety device for press machine and shearing machine (paper cutting machine) in
Japan, make sure to attach cable protection pipes.
Cable color and pin position
Reference
•
When the synchronization wires are not connected, the GL-RHG operates in optical
synchronization system.
•
When optical synchronization system or one-line system is applied, the input and output
functions on the transmitter are not available.

I/O circuit diagram
Reference
•
Grey wire (FE) is electrically-connected to the light curtain body case.
•
The light curtain body case and internal power signal lines are coupled by capacitor (3 kV, 100 pF).

DANGER
•
Cables must be within the lengths specified. Failure to follow this specification may
cause improper operation of safety functions, and may create a dangerous situation.
•
The series connection cable cannot be cut or extended. If the cable is cut or extended,
safety features may not operate properly. Do not allow this to happen as it is extremely
dangerous.
