1-2 Part Description

Beam center-line: An optical path joining the optical center of the emitting element on the transmitter to

the optical center of the corresponding receiving element on the receiver. The GL-RHG must be installed so that the beam center-line mark on the transmitter and

that on the receiver face one another and are located at the same height. Protective height: The height from the top beam center-line to the bottom beam center-line (length). Detection height:

An object approaching the protective zone from the top of the protective height is first

detected at point A, which is the distance of the detection capability from the top of the

protective height. The equivalent position on the bottom is called point B. The height from

the top edge of the specified target detection capability that exists at point A to the bottom

edge of the specified target detection capability that exists at point B is called the "detec-

tion height".

The following calculation formula can be defined:

Detection height = "Protective height" + (2 × "specified target detection capability") –

"beam axis diameter". *

Refer to the following diagram for an explanation of beam center-line, protective height and detection height.

Protective zone: The zone in which the specified target detection capability can be detected. The detec-

tion zone of the GL-RHG indicates a square area formed with the protective height and

the operating distance. When an object of the specified target detection capability is

present in this area, the light of the GL-RHG is blocked, and then the OSSD goes to

OFF state. Detection zone:

The square area formed with the detection height and the operating distance, which is

broader than the protective zone. When an object of the specified target detection capabil-

ity is present in this area, the light of the

OFF state.

T1 T2

The OSSD is a safety-related control output. It connects to an external device (load), such as an FSD or MPCE. The GL-RHG generates self-diagnosis signals on its internal control circuit to perform diagnostics on the output circuit (OSSD). These signals periodically force the OSSD into a temporary OFF state when no interruption exists in the protective zone.

If the internal control circuit receives a feed-back signal (OFF signal) based on the self-diagnosis, the GL-RHG determines that its output circuit is operating normally. If this OFF signal is not returned to the internal control circuit, the GL-RHG determines that there is a problem in its output circuit or wiring and goes to the error condition.

Functions and Features

For the wiring between the GL-RHG and the safety-related part of a machine control system, both OSSD 1 and OSSD 2 must always be wired to a safety-related part of the machine

DANGER

control system in order to ensure safety. If only one OSSD is wired to the safety-related part of a machine control system, it results in significant harm to the machine operators, including serious injury or death, if OSSD malfunction were to occur.

Point

The devices connected to the OSSD, such as safety relay or contactor, should not respond to

these temporary, self-diagnostic OFF-signals.

External Device Monitoring (EDM Function)

EDM (External Device Monitoring) is a function of the GL-RHG that monitors the state of the control devices which are externally connected to the GL-RHG. The GL-RHG can detect a fault, such as welded contacts on external devices, as long as the EDM function is activated. See "Functions" (page 2-4) for the information of wiring system and cable type to activate this function.

Wiring

Reference

When using the 11-core cable and not using the EDM function, short-circuit the EDM input to AUX

output (Red wire on the receiver).

Time chart

(1) If the GL-RHG detects the operation of the external devices within the specified period of time (0.3 s)

after the operation of OSSD (ON to OFF, or OFF to ON), the GL-RHG continues normal operation.

(2) Unless the GL-RHG detects the operation of an external device within the specified period of time

(0.3 s) after the operation of OSSD (ON to OFF, OFF to ON), the GL-RHG goes into an error condition due to an EDM error.
