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

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.

Temporary Suspension of Safety Function

Muting function

The muting function is used to temporarily suspend the GL-RHG's safety functions while the GL-RHG system meet the specified condition for muting. Before this function can be used, the outputs from the muting devices must be connected to the muting input terminal on the GL-RHG. In addition, the configuration software provides the user with the opportunity to select the beam axes to be in the muted condition. See "Functions" (page 2-4) for the information of wiring system and cable type to activate this function.

Point

For more specific examples of operations or for information about installation when using the

muting function. "Example: Muting function with 2 muting devices (Sensors)" (page 2-10)

• Since the muting function temporarily suspends the safety functions of the GL-RHG, additional safety measures are required for the entire machine on which the GL-RHG is installed. This is to ensure safety while the muting function is activated.

• The muting devices, the installation of those devices and the procedure to activate the muting function must fulfill the conditions specified in this user's manual and the requirements of the laws, rules, regulations, and standards in the country or region in which the GL-RHG and those devices are used. Failure to follow this warning may result in significant harm to the machine operators, including serious injury or death.

• When you install the muting devices (such as sensors or switches), the following conditions must be fulfilled. (1) Muting devices must be installed so that the muting function cannot be activated if the

machine that the GL-RHG is on is in the middle of a hazardous cycle or period.

(2) Muting devices must be installed so that the muting function cannot be activated by

personnel approaching the protective zone of the GL-RHG.

• Only responsible personnel should be allowed to install or wire the muting function or muting devices.

• The muting devices must be installed in such a way that only responsible personnel can change the installation or orientation by requiring special tools or keys to access the devices.

• The whole responsibility for use of the muting function must rest with the customer. Those who use the muting function must fulfill all of the requirements related to muting functions. KEYENCE accepts NO responsibility or liability for any damage or injury due to unauthorized installation, unauthorized usage or maintenance methods that are not specified in this user's manual and/or due to noncompliance with the laws, rules, regulations and standards set fourth by the country or region in which the GL-RHG is used.

• The installation of a muting lamp may be required by the laws, rules, regulations, and standards in the country or region in which the GL-RHG is used if you apply the muting function. It depends on the machine application and/or the result of your risk assessment. If it is necessary for you to provide the muting lamp, you must fulfill the requirements because you are fully responsible for installation of the muting lamp.

Devices used for muting function

Functions and Features

 Muting device

• The muting device output must be N.O. (normally open).

• A PNP output muting device is required when using the PNP output type cable and an NPN output mut-

ing device is required when using the NPN output type cable. The muting device must be capable of 2 to 3 mA current.

• Do not use one muting device with multiple outputs in place of two or more muting devices. (Only one output per one muting device must be used.)

• If the muting device has a timer function that can adjust the output timing, do not use that function.

 Muting lamp

When using the muting lamp, it must meet the following conditions.

For an incandescent lamp : rated 24 V DC, 1 to 5.5 W For an LED indicator : rated current consumption must be 10 to 230 mA.

Detailed operation

 Conditions for initiation of muting

Muted condition is initiated if all of the following conditions are met:

• Muting input 2 turns ON within 0.04 to 3 seconds after muting input 1 turns ON

• GL-RHG detects no interruption in the protective zone

• OSSD is in the ON state and remains for 0.5 seconds or more.

 Conditions for termination of muting

Muted condition is terminated if one of the following conditions is met.

• Either of the muting inputs goes to the OFF state for at least 5 ms.

• Light curtain goes to an error condition

• Wait input goes to ON state

• The power supply is interrupted or restored.

• Maximum muting period of approx. 5 minutes has been passed.

Reference

When the GL-RHG is interrupted, the GL-RHG cannot go to the muted condition. In this case, you can apply override function to suspend the safety functions temporarily. "Override function" (page 2-20)

Functions and Features

Point

Reference

• If muting input 2 turns on outside the T1 range after muting input 1 turns on, the GL-RHG will not mute and remains in normal operation. (The GL-RHG does not go into an error condition.)

• If only muting input 1 or muting input 2 turn OFF and back ON, the GL-RHG will not return to the muted condition. To return to the muted condition, both muting inputs 1 and 2 must first turn OFF and the muting conditions must be met again.

• If the GL-RHG power is turned ON while the GL-RHG is in the muted condition or either muting input 1 or 2 is on, the GL-RHG will not go to a muted condition. In this case, both muting inputs must be turned OFF and the muting conditions must be met again.

• The function indicators and 7-segment display indicate each condition.

 Explanation

(1) The GL-RHG is not muted when the mold is at or stays at the bottom dead

center of the press cycle. At this point, the GL-RHG continues normal operation and the OSSD goes OFF if the GL-RHG gets interrupted.

(2) When switch A1 turns ON first, and then switch A2 turns ON, the GL-RHG

goes into the muted condition and the OSSD does not turn OFF, even if the GL-RHG detects an interruption.

(3) The GL-RHG continues the muted condition because both switches stay

turned ON and the mold continues to stay at the top dead center position.

(4) The GL-RHG will go back to normal operation (not muted) as soon as sen-

sor A1 turns OFF after the mold starts downward.

(5) The GL-RHG continues normal operation while the mold is going down-

ward.

Override function

Functions and Features

During normal operation, the OSSD goes to an OFF state if the muting function is deactivated and an interruption remains in the protective zone of the GL-RHG. The OSSD OFF state will remain until the obstruction is removed.

The Override Function allows a temporary manual suspension of the GL-RHG safety functions. This makes it possible to remove the obstruction remaining in the protective zone of the GL-RHG. (Machine is able to be manually operated on a temporary basis because the safety function of the GL-RHG is temporarily suspended.) See "Functions" (page 2-4) for the information of wiring system and cable type to activate this function.

• The override function allows a temporary manual suspension of the GL-RHG safety functions. Thus, in order to ensure safety while the override function is activated, additional safety measures are required for the entire machine system on which the GL-RHG is installed.

• The devices, the installation of those devices, and the procedures to activate the override function must fulfill the conditions specified in this user's manual as well as the requirements of the laws, rules, regulations, and standards in the country or region in which the GL-RHG and those devices are used. Failure to follow this warning may result in significant harm to the machine operators, including serious injury or death.

• The override function allows a temporary manual suspension of the GL-RHG safety functions. Manual operation devices are required to activate the override function. When installing the devices to activate the override function, the devices must be installed so that the whole hazardous zone can be checked by responsible personnel and that the device operators are not in the hazardous zone.

• Be sure to confirm that there is nobody in the hazardous zone, before the override is activated. Failure to follow this warning may result in significant harm to the machine operators, including serious injury or death.

2-6 Wait Input Function

The wait input is a NON-SAFETY-RELATED function. This function puts the OSSD into an OFF state through a signal from an external device (non safetyrelated device). See "Functions" (page 2-4) for the information of wiring system and cable type to activate this function.

 How to use

(1) The signal from the external non safety-related control device is connected to the wait input. When

this signal is ON, the OSSD of the GL-RHG goes to OFF.

(2) This function is useful for testing and making sure that the machine which the GL-RHG is installed on

can stop within the specified period of time when the OSSD goes into an OFF state.

The wait output is not allowed to be connected to the safety output provided from the

DANGER

safety-related control system. Connection to the safety output of the safety-related control system may result in significant harm to the machine operators including serious injury or death.

The safety distance is the minimum allowable mounting distance between the GL-RHG and the hazard point, which allows complete stoppage of hazardous motion before an individual reaches the hazard point. The starting point (origin) for the safety distance must be the center line of the GL-RHG's surface. (See below figure.) The following safety distance calculations are for cases where the protective zone is perpendicular to the

Installation to a Machine

direction of approach. For all other cases, you must refer to the laws, rules, regulations or standards of the country in which the GL-RHG is installed.

DANGER

The installation of the GL-RHG must ensure the required safety distance in compliance with the requirements of laws, rules, regulations and standards of the country or region in which the GL-RHG is installed. Mounting the GL-RHG closer to the hazard point than the calculated safety distance can result in serious bodily injury or death.

3-2 Safety Distances

 Example 1: ISO13855 (EN ISO13855)

Safety distance calculation according to ISO13855:2010 (EN ISO1385:2010) (in a case where the

protective zone is perpendicular to the direction of approach)

Equation A: S = (K × T) + C

S : Safety distance (mm) K : Approach speed of the body or parts of the body into the protective zone (mm/s) T : Overall system stopping performance (s) (T= t1 + t2) t1 : GL-RHG maximum response time "Response time (OSSD)" (page 7-5) t2 : Maximum time required by the machine to stop after receiving a signal from the protective

equipment (GL-RHG), (s)

C : Additional distance (mm) calculated from the GL-RHG detectable capability. See example

below.

 Calculation example for a detection capability of 40 mm (1.57") or less

The safety distance is calculated using Equation (A) and the parameters established in ISO13855 (EN ISO13855) with K = 2,000 mm/s and C = 8 (d - 14 mm). C is a value determined according to the GL-RHG detection capability diameter (mm), (d). The value (d) must be great than or equal to 0. This section provides an example of the calculation when using the GL-R08HG (8 beam axes) which operates in wire synchronization system.

Equation B: S = 2,000 mm/s × (t1 + t2) + 8 (d - 14 mm)

t1 = 6.6 ms and d = 25 mm according to the specification, and if t2 = 50 ms: S = 2,000 mm/s × (0.0066 s + 0.05 s) + 8 (25 mm – 14mm) = 201.2 mm (7.92")

Installation to a Machine

The safety distance calculated using the above Equation (B) must be 100 mm (3.94") or more. (From ISO13855 Clause 6.2.3 and EN ISO13855 Clause 6.2.3)

If on the other hand the safety distance calculated using the above Equation (B) exceeds 500 mm (19.69"), set K = 1,600 mm/s and calculate the safety distance again using Equation (A). If the calculated safety distance is less than 500 mm (19.69"), you still must use a safety distance of S = 500 mm (19.69"). (From ISO13855 Clause 6.2.3 and EN ISO13855 Clause 6.2.3)

of the machine cycle to be completed. This value includes portions of time that vary by machine type and by the safeguarding device applied.

Dpf : The distance (depth) penetration factor. This value varies depending on the GL-RHG

One of the accepted values for K is the hand speed constant. (It is usually considered as the horizontal motion of the hand and arm while seated). The common value is 1.6 m/s (63inch/s), although other values (typically greater) are also used. The hand speed constant does not include other body movements, which can affect the actual approach speed. Consideration for the above factors should be included when determining the speed constant for a given application. OSHA 1910.217(c) provides K = 63 inch/s (= 1,600 mm/s) as a recommended value.

For more detailed information, such as calculating the value of "T", see ANSI B11.19-2010, Annex D.

 Example 4 When using GL-RHG as safety device for press machine in Japan

Safety distance calculation according to the Standard for power press machine

The following is the safety distance calculation formula described in Article 43 of "Standard for the mechanical structure of power presses (Notification of the Ministry of Health, Labour and Welfare No. 4

Installation to a Machine

dated at January 12, 2011)" based on Article 42 of the Industrial Safety and Health Act. The following example shows reference values. When installing GL-RHG to the press machine, follow the "Standard for power press machine".

Equation D = 1.6 × (Tl + Ts) + C

D : Safety distance (mm) Tl : GL-RHG response time (ms) Ts : Maximum time required by the press machine to stop after receiving a signal from the

GL-RHG. (ms)

" Response time (OSSD)" page 7-5

C : Additional distance according to Detection capability in the following table

Detection capability (mm) Additional distance (mm)

30 or less 0 more than 30, less than 35 200 more than 35, less than 45 300 more than 45, less than 50 400

The safety distance (D) is calculated using the equation and the installation distance (A) is determined. When the horizontal distance between the optical axis and the front end of bolster exceeds 400mm or even less, if a person may possibly enter between the optical axis and the front end of bolster, install a supplementary axis or an additional guard.

z Example

The following example shows when using GL-R24HG (optical axis: 24) with the wire synchronization system. According to the specifications of GL-R24HG, Tl = 7.0 ms, continuous light-blocking width (Detection capability) 25 mm, thus, additional distance C = 0 mm and Ts = 180 ms.

D = 1.6 × (180 + 7.0)

= 299.2 mm

The safety distance is calculated as 299.2 mm.

3-3 Light Interference Prevention Method

When more than one GL-RHG systems are installed, the OSSD may go to the OFF-state by the light interference between GL-RHG units. There are three light interference prevention methods as follows.

Light Interference Prevention Function

 When wire synchronization or one-line system is applied

The light interference prevention function automatically reduces mutual interference between GL-RHG units.

 When optical synchronization system is applied

The light interference prevention function is applied according to Channel configuration. The mutual interference is reduced between GL-RHG units with Channel A and Channel B. The mutual interference is not reduced between GL-RHG units with Channel 0 and Channel 0, GL-RHG units with Channel 0 and Channel A, or GL-RHG units with Channel 0 and Channel B.

Channel is configured by using the setting switch on the lower part of front side of GL-RHG units. Configure the same Channel to the setting switch on both the transmitter and receiver. For more information about the setting switch, see "Part Description" (page 1-8). When the GL-RHG is in series connection, the setting switch configuration of the main unit is applied regardless of the setting switch configuration of the sub unit.

Interference due to installation

If more than three GL-RHG systems are installed and not connected in series, they should be installed according to the following information.

Installation to a Machine

(1) Install shielding (2) If shielding is not possible: Ensure the

transmitters are back-to-back, so as not to directly face each other.

(3) Tandem installation: Alternate the transmit-

ter and receiver sides.

(4) Side-by-side installation: Alternate the

transmitter and receiver sides.

(5) If the transmitters and receivers must be on the same side: Ensure adequate distance between

curtain pairs.

Point

3-12

When installing the GL-RHG in method (2), (3) or (4), installing the devices too closely may cause reflection in the plane of detection and thus cause interference. Total prevention of light interference may not be possible even following methods (1) to (5). The operator in charge must consider adequate light interference prevention method according to the machine or system where their GL-RHG is installed.

Precautions on Wiring and Power Supply

• The two OSSD outputs provided in the GL-RHG must both be used to establish a safetyrelated machine control system. Establishing a safety-related machine control system with just one OSSD output cannot be done because a potential OSSD output malfunction could result in significant harm to the machine operators, including serious injury or death.

• When using PNP output cables, do not cause a short circuit between the OSSD output and +24 V. Otherwise, OSSDs stay ON and create a dangerous situation.

• When using PNP output cables, be sure to connect the load between the OSSD and 0 V to avoid a dangerous situation. If the load is incorrectly connected between the OSSD and +24 V, the logic of OSSD operation will be reversed, and then turn ON when the GL-RHG detects the interruption in the protective zone. This is a dangerous situation.

• When using NPN output cables, do not cause a short circuit between the OSSD output and 0 V. Otherwise, OSSDs stay ON and create a dangerous situation.

• When using NPN output cables, be sure to connect the load between the OSSD and + 24 V to avoid a dangerous situation. If the load is incorrectly connected between the OSSD and 0 V, the logic of OSSD operation will be reversed, and the OSSD will turn ON when the GL-RHG detects the interruption in the protective zone. This is a dangerous situation.

• Regardless of whether the cables are PNP or NPN type, you must fulfill the requirements of Clause 9.4.3 in IEC60204-1: 2005 for protection against maloperation due to earth fault.

• All outputs, other than OSSDs, are not allowed to be used as safety outputs for a safetyrelated machine control system. Usage of these output functions, other than OSSDs, as a safety output could result in serious injury or death.

• To avoid the risk of electric shock, do not connect any of the GL-RHG inputs to DC power sources outside of the range of 24 V DC +20% or to any AC power source.

• To avoid the risk of electric shock, be sure that any hazardous voltage is isolated from all wiring of the GL-RHG with reinforced insulation or double insulation.

• Do not install the electric wiring of the GL-RHG together with or in parallel with any highvoltage electrical or power lines.

Power supply

In order to meet the requirements laid out in IEC61496-1, UL61496-1, EN61496-1 and UL508, the power supply for the GL-RHG must meet the conditions listed below.

• A rated output voltage of 24 V DC (SELV, Overvoltage Category ) within ±20%.

• Double insulation or reinforced insulation between the primary and secondary circuits.

• Output holding time of 20 ms min.

• A power supply must meet the requirements of the electrical safety and electromagnetic compatibility

(EMC) regulations or standards in all countries and/or regions where the GL-RHG is used.

• A secondary circuit of power supply (output) must meet the requirements for Class 2 Circuits or Limited Voltage/Current Circuits specified in UL508, if the GL-RHG is used in United States or Canada.

If the power supply for the GL-RHG is shared with other electronic devices, voltage reduction to the GL-RHG may occur due to the temporary increase of the current consumption on these devices, or the GL-RHG may be affected by the noise generated by these devices. When these situations occur, the GL-RHG may go into error condition. It is therefore strongly recommended that the power supply for the GL-RHG is dedicated solely for use with the GL-RHG, the muting device connected to the GL-RHG and the load for the GL-RHG. It should not be shared with other machines, devices or electronic devices.

4-4 Cable Specification

Connector

(1) Cable length

1. Optical synchronization system and 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. There is no limitation for the total length of series connection cables when the GL-RHG is connected in series.

Wiring

2. One-line system The sum of the length for all of the unit connection cables, extension cables and series connection cables must be 30 m or less.

• 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.

DANGER

(2) Minimum cable bending radius : 5 mm

(3) Identification of connector cables

• 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.

Connector colors PNP output type cables or series connection cables : Black connectors NPN output type cables : Grey connectors

Point

(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 protection pipe" (page 1-4) "3-6 Attaching the Cable Protection Pipe" (page 3-16)

4-6

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.
