Introduction

The Microguard is the latest in infrared safety curtain technology. Contained in the main housing (Controller Module) is a diverse redundant architecture that is designed to detect internal failures in the Emitter pylon(s), Receiver pylon(s), and the Controller Module

which will immediately send a “STOP” command to

the machine, thus being “FAIL-SAFE.” Failures are immediately reported on the diagnostic message display for immediate evaluation.

Diverse redundancy means that there are at least two ways to detect a system failure, two ways to shut it down, and that the two methods of detection and shut down use different techniques. This eliminates the chance an inherent fault in one circuit will effect the other. For example: The stop circuit output contacts run through two relays and both are monitored for correct position through a second set of contacts on each relay. A special circuit monitors those contacts, but a different circuit (a

test circuit) monitors the rst circuit to make sure that it

is functioning correctly. Two different microprocessors isolated from one another each monitor the same signals and monitor each other. Either microprocessor can turn off the output relays, but it requires both to turn them on. Special watchdog circuits on the microprocessors and on the output relay circuits prevent an unsafe condition by turning off both outputs relays should either or both microprocessors become erratic.

With the aid of advanced microprocessor technology, the MicroGuard can not only detect a fault in the light curtain but spell out the exact problem. This advancement is a great help during alignment, use, and servicing of the light curtain. It not only can detect shorted and open infrared emitters, but indicate which emitters have failed, allowing the faulty board to be replaced.

Built into the MicroGuard is an optically coupled external relay check which can detect open or short circuits, a Cincinnati Interface, provision for auxiliary output contacts, and external voltage check input. The power supply is designed to accommodate most voltage requirements, from DC to AC (see Specications).

is placed between them, the beam is broken and the absence of a beam is observed by the Controller Module

which de-energizes the output relays and opens the

circuit it is connected to.

The System. The MicroGuard employs infrared technology in a small sealed NEMA 4 aluminum housing which provides harmless invisible protection and an unobstructed view of the guarded area. The Microguard consists of three parts: an Emitter pylon(s), Receiver pylon(s), and Controller Module. The Emitter pylon(s) contains infrared light emitting diodes spaced .5” or 1” apart down the entire length of the pylon. The Receiver pylon(s) contains an equal number of infrared detector’s and transistor receivers also spaced .5” or 1” apart. The Controller Module contains diverse redundant technology that includes two different microprocessors, self-checking circuitry, power supply, safety output contacts, and a diagnostics display.

System Safety. The MicroGuard employs diverse redundant technology that provides a backup for every system that could cause an unsafe condition. Upon power up, all systems are checked before activating

the output relays. Once the unit passes the initial

tests and activates the system it is then tested by both microprocessors and other circuits once per scan of the light curtain. All signals are presented to both microprocessors, but are isolated from one another to prevent a failure of one microprocessor should the

other crash. Other circuits detect short circuits, open

circuits, proper voltage, proper oscillation, etc. The use of special dual force guided safety relays assure that if one fails, the other can safely shut down the unit. Additionally, watchdog circuits on the relays prevent an unsafe condition even if both microprocessors failed. All the standard and optional features that run on the MicroGuard are designed with safety in mind:

The Floating Blank option allows only one object to be

placed into the light curtains eld of view. Even if the object is smaller than the allowed size, a second object

will cause the unit to go RED.

As the MicroGuard is a single function device, that of

sensing an unauthorized intrusion into a guarded area

while simultaneously determining that it is capable of sensing such an intrusion, any internal malfunction will manifest itself with a RED condition shut down.

Theory of Operation. The MicroGuard guards an area by projecting a curtain of infrared light across it. It forms

a curtain by utilizing infrared emitters in line very close

together on .5” or 1” centers. This close spacing makes it impossible to place a body part through the curtain without detection. For every infrared emitter there is an infrared detector directly opposite. When an obstruction

The Auto Blank option programs in the exact size and

location of an object automatically and thus can detect any movement in the object and shut down the light curtain, which must be reset with a key.

The External Relay Check can detect both an open or a short in the external relay or its wiring. The standard Cincinnati Interface provides a means to assure that the light curtain can open up i t s o u t p u t r e l a ys between press cycles.

Introduction

Immunity to EMI/RFI. The entire system is shielded,

including the pylon cables. The use of MOV’s, lters,

and chokes make it immune to the noise found in the industrial environment. Even the software embedded into the dual microprocessors is written to cope with a noisy environment.

CE Approved. CE approval was third party certied by UL / DEMKO to IEC61496-1,-2. CE approved units offer

+/-2deg beam angle, which is tighter than the standard Microguard.

Standard Features

Metal Box Controller Module

Auxiliary Output Contact (K3)

Description: K3 relay uses the same driver circuitry as the K1 relay, but has its own relay checking circuitry. This means that you should never use the K3 relay in series with the K1 relay unless you use K2 in another stop circuit.

Usage: K3 has both N.O. and N.C. outputs off the

same common. This can be used in conjunction with the standard output contacts. Never just use K3 by itself or with K1.

N.O. contact is closed when the curtain is GREEN.

N.C. contact is open when the curtain is GREEN.

Cincinnati Interface

Description: Provided to allow an external device to determine if the light curtain is still capable of shutting down the safety control circuit. The Cincinnati Interface allows an external device to override the light curtain, initiate a RED condition, and open up the standard output relay contacts.

Application: Cincinnati Press, PLC

Usage:

Type1: The press interface provides 24VDC when it wants the guard to de-energize (go RED). Connect this

press signal to Terminal #5 and Ground to Terminal #6.

Type 2: The press interface provides Ground when it

wants the guard t de-energize (go RED). Connect this

signal to Terminal #6 and attach nothing to Terminal #5. You must install the jumper J8 (bottom board).

(see Installation Procedures, “Controller Module Setup”)

External Relay Check

Description: Allows the MicroGuard to monitor a pair of external relays in series using the external relays secondary set of DRY contacts, provided that they are N.C. and captive contacts. This captive or force-guided contact will maintain the identical position as the primary set of contacts on the external relays, except that the secondary set of contacts are wired up to signal the

reverse of the primary. (i.e., primary are N.O., secondary

are N.C.) The circuit looks for both closure and opening of the external relay contacts. This system is the only safe External Relay Check.

Application: Monitoring external relay contacts for shorts or opens.

Usage: Follow Figure 1 for wiring your external relays.

You must rst activate this feature by using the spare

jumper and placing it across J19 labeled EXT (door board). This system requires that both N.C. relay

contacts be wired in series then back to the terminals inside the Controller Module. Relay contacts must be DRY contacts. Both external relay contacts must be closed when the light curtain is RED within .25 sec or an

Figure 1: Wiring External Relays

12 13 14 15

error will occur (this detects an open or a contact weld). When the light curtain goes GREEN it will record the opening of the external relay. If the light curtain goes RED again without ever sensing the opening of the external relays, an error will occur (this detects a short or failed relay) and cause the light curtain to lock up and must be powered down to clear the error. A Red LED (D14) will light up when external contact is closed (see Installation Procedures, “Controller Module Setup.” )

Captive Contact Denition: one pole inside the relay always maintains the identical position to the other pole. (i.e., if one pole contact welds closed, the other pole

remains closed even when the relay coil is de-energized.

NOTE: Use shielded cable for relay check inputs.

Standard Output Contacts (K1 & K2)

Description: Both K1 and K2 relays each have there own relay driving circuitry and relay checking circuitry and are fully independent of each other having there own output terminals. The MicroGuard checks the position of all the relays and shuts them all down if any are found in the wrong position. In order for the system to remain safe during a single failure of one relay, you must be using the relays such that the second relay can

still shut the system down if the rst one ever fails. This

can either be by wiring both relays in series or using both relays separately in two control circuits.

Usage: K1 and K2 have separate outputs and both must be used either together in series with your stop circuit or separately in two stop circuits. K1 and K2

outputs are N.O. and close when the curtain is GREEN

only.

Standard Features

Metal Box Controller Module

Fault Relay Output

Description: It will not change states due to curtain blockage.

Application: Can be used to signal a remote station of an unexpected machine shut down.

Usage: The fault relay provides a dry contact that is open when good and closed when a fault or loss of power occurs. Use the alarm contacts on the power

supply board. The dry contact is isolated up to 120VAC.

To Actviate: Install jumper on J17 (bottom board) top 2 pins. Install jumper on J9 (door board) between Latch and Close pins (left side). This feature will disable remote latching. D21 will light up to show the relay is active.

Optional Features

Metal Box Controller Module

Auto Blank [patent # 5,243,183]

Description: Allows user to program the exact size and

location of an object (i.e., a conveyor, table, work piece, etc.) automatically and can detect any movement in the object causing the light curtain to shut down.

Application: With the obstruction in place, turn the

key swith from “OFF” to any mode of operation. If the object(s) do not exceed the total allowable size, the unit will energize the safety outputs.

Standard Operation: If the obstruction is moved or

removed, the unit will issue a “MOVE” fault, but will re-energize the safety outputs when the obstruction

is returned to the original position. Standard operation allows for a total of eight beams to be blocked anywhere in the curtain (they do not have to be next to each other).

Optional Operation: If the obstruction is moved or

removed, the unit will issue a “MOVE” fault and lockup,

requiring you to re-program the obstruction.

Troubleshooting: If you get a “MOVE” fault when

the obstruction did not move, it is possible that you are just barely covering a beam and either vibration or

reections are causing the beam to become uncovered.

The uncovered beam then causes a fault.

To Activate Feature: This feature must be ordered and requires exchanging the computer chips (see Installation Procedures, “Controller Module Setup”).

WARNING: Leave key switch in OFF/RESET

position while installing, setting up, and testing the light curtain. Use Auto Blank only after you are able to get a clear signal from the curtain with no obstruction.

The term “Auto Blank” is an abbreviation which stands for Automatic Programmable Beam Blanking. Auto Blanking is controlled by a multi-position keyswitch and has three distinct modes of operation:

1) Must be reset if auto blank obstruction moves

or g uard penetrated. The AUTO BLANK

obstruction must remain in its exact location

permanently. Any movement in the AUTO BLANK

obstruction and/or additional guard penetration will latch the light curtain in a RED condition and must be reset via the keyswitch.

NOTE: If no obstructions were programmed in, the guard will still latch in a RED condition should the guard be penetrated.

2) Must be reset if auto blank obstruction moves. The Auto Blank obstruction must remain in its exact location permanently. This works like Mode 1 except guard penetrations will not latch in a RED condition.

3) Mode 2 with oating blank. This mode works like Mode 2 with the addition of a Floating Blank which is set to allow a one beam float (see

Optional Features, Floating Blank”).

NOTE: If no obstructions were programmed in, the guard will still allow a one beam oat.

Programming: To program, turn the keyswitch into the

OFF/RESET position and place the obstruction(s) in the

guarded area. Now, turn the keyswitch into the desired

mode of operation. The exact size and location of the

object(s) are now in memory. The Depth Penetration Factor D(pf) must be set to account for the one beam

oat (see Optional Features, “Floating Blank”).

MOVE Auto Blank obstruction moved.

IMPORTANT: Place Auto Blank keyswitch into

OFF/RESET position and remove any obstructions

while aligning light curtain. Do not use Auto Blank until light curtain is correctly aligned (see Installation Procedures, “Alignment Procedure”).

The keyed selector switch is designated to be supervisory controlled. After installation, the safety key should be removed and controlled only by the safety supervisor or

authorized plant personnel.

Optional Features

Metal Box Controller Module

Emergency Stop Input(s)

Description: This option utilizes two normally-closed

emergency stop contacts to achieve a Catagory 4 safety level, per EN 954-1. If either or both emergency stop contacts open, power to the safety output relays is

removed, causing the relays to de-energize and send

a stop signal to the guarded machine.

Application: This protects against a safety switch contact failure or wiring fault. A contact failure or wiring short will inhibit the system reset, causing the system’s Diagnostic Message Display to indicate an Emergency Stop Input Failure.

Usage: Wire one N.C. contact between Terminal #1 and #4. Wire the second N.C. contact between Terminal #3 and #4 (located on power supply board). This option

cannot be used with Mute-Out. Alterative option: Wire rst N.C. contact between Terminal #6 and #4. Wire

second N.C. contact between Terminal #7 and #8. This option cannot be used with Cincinnati or External relay

checking features. To reset ESTOP: Close both ESTOP

inputs, then use the latching relay reset input to clear

ESTOP fault (cycle closure between Terminal #2 and 4).

DeviceNet

Description: Optional external board that is mounted

to the door board inside the Metal Box Controller Module. External board comes with its own directions.

Floating Blank

Description: On a press brake, the Floating Blank permits the work piece to be placed in the guarded area and can be moved around as long as it does not exceed the object sensitivity selected. A keyswitch by default allows for

zero, one, two, or three beams to be blocked anywhere

in the curtain as long as all the blocked beams are next to each other. The customer may request different

blanking sizes for different applications. The Minimum Object Sensitivity (MOS) and the Depth Penetration

Factor (DPF) change when the key switch position is changed. The DPF is used to compute the safety distance.

Location of the light curtain from the point of operation must include the depth penetration factor D(pf) equivalent to the beam spacing.

Minimum Object Sensitivity indicates the minimum

size required to cause the light curtain to detect an object even if it is moving (oating). If the obstruction is

slightly smaller (less than .25”) than the stated number, the light curtain may blink RED/GREEN when the

object is moving in the eld of view. If the obstruction

is smaller than the stated number by at least .25”, then the light curtain will stay GREEN as long as there are no additional obstructions.

Optional Features

Figure 2: Bottom board inside Control Box

Metal Box Controller Module

Guarding Mute-Out

Description: The Guarding Mute-Out option is the

only fault-tolerant method of by-passing the light curtain

during the nonhazardous portion of your machine cycle

(i.e., up stroke of press).

Application: Allows any object to pass through the light curtain without opening the stop circuit and interrupting the machine cycle (i.e., the curtain stays GREEN).

Usage: The Guarding Mute-Out portion of the cycle

occurs between the pinch point and top stop (about

180° to 300°) or any non-hazardous portion of your

machine cycle.

You must power up the MicroGuard out of the Guarding

Mute-Out condition, any other condition will cause an

error to occur and you will have to power down the guard

to reset it. When in Guarding Mute-Out, the MicroGuard

will display “MUTE.” If LS4 or LS5 limit switches are ever caught out of sequence, the guard will fault and issue

an error message of “MUTE-OUT SWITCH FAULT” or “SLV MUTE-OUT SWITCH FAULT.”

Use only the shielded cable provided! Do not route cable along with high voltage lines.

1) Connect one side of LS4 and LS5 to Terminal 4 inside MicroGuard.

2) Connect other side of LS4 to Terminal 1 inside MicroGuard.

4) Connect other side of LS5 to Terminal 3 inside MicroGuard.

If both signals remain in the same state (i.e., both closed or both open) for more than 100mSec a fault will be issued.

NOTE: To by-pass this feature, jumper LS5 (terminal

3) to terminal 4.

To Activate Feature: This feature must be ordered and requires exchanging the computer chips (see Controller

Module Setup section for a diagram).

Latching Relays

Description: Light curtain wil stay in a RED condition when blocked, even when the blockage is removed and the guard is clear, until signalled to try and reset back to GREEN (unblocked).

If you have Auto-Blank, this option allows you to reset penetration without reprogramming the Auto-Blank.

Application: This is used for guarding an area against intrusion. Without this option the light curtain would only stay RED (safe) as long as the intrusion was detected

(i.e., nger, hand, etc.).

Usage: Wire a N.O. button between Terminals 2 and 4. You can remote this button if you want. This feature must be

ordered and requires exchanging the computer chips. Also, install jumpers on J15 and J17 on bottom 2 pins of each (bottom board).

Installation Procedures

Metal Box Controller Module

WARNING: The entire machine safety system must be tested at the start of every shift. Machine testing should include: (1) proper machine operation and stopping capability; and (2)

verication of proper installation and settings of

all point of operation guards and devices before the operation is released for production.

CAUTION: The MicroGuard should be mounted

in a manner so that only authorized personnel can

change the mounting or location.

CAUTION: Additional guards may be required to prevent the operator from standing between the light curtain and the point of operation.

1) Test the unit before you mount it on your equipment by running the light curtain with the pylons butted up to and facing each other. Each cable and pylon

is labeled “EMITTER” or “RECEIVER”. You will

feel a snap when the plug is fully seated and locked onto the connector. Attach a line cord to the power terminals for testing. If the light curtain goes GREEN, you are ready to proceed with the next step. If the light curtain stays RED, call your dealer for help in determining the problem.

2) Determine the Safety Distance of the light curtain from the point of operation (see Installation

Procedure, “ANSI Standard B11.19-2003”).

3) Determine if any part of the Microguard is to be directly subjected to either excessive shock and/ or vibration. If so, mount the subjected parts to your equipment using shock-mounted devices

(such as Part# 21-019). Shock and/or Vibration

damage is not covered under warranty.

4) Place the Controller Module in an accessible location where the cables can reach the pylons. Dress the cables to avoid crushing, kinking, or cutting (see Dimensions, “Controller Module“).

5) Wire power to the proper terminals and check that the voltage is correct (see Installation Procedures,

“Controller Module Setup”).

Power for the MicroGuard should not be down

stream of noisy inductive devices (i.e., motors, solenoids, etc.), it should be in front of them.

6) Interface the light curtain standard relay output contacts to the safety stop circuit(s). You must use both K1 and K2 output contacts. Do not use an

external relay(s) unless you use the external relay checking feature.

7) Interface any remaining optional input or output lines to their proper terminals (see Optional

Features).

8) Align the light curtain (see Installation Procedures, “Alignment Procedure”).

9) Use a round test piece (i.e., dowel rod) that has a diameter equal to the minimum object sensitivity. Check and assure stop of machine when signal of penetration is made. Minimum object sensitivity goes up if you use Auto or Floating Blank options.

10) Mechanical guarding may also be required from reaching around the light curtain to the point of operation (see Installation Procedures, “Safeguarding with Mechanical Guards”).

11) For installation assistance, please call your dealer.

NOTE: For location of pylons in relation to the hazard area, see Appendix B: Regulations and Guidelines, “Federal Register 1910.217 (c) (3) (iii) (e)” and Installation

Procedures, “Safeguarding with Mechanical Guards”.

4) Mount both pylons with the connector side in the same direction mechanically aligned with one another. Locate pylons so the working zone

is guarded from reaching around, over, and under the light curtain system to the point of operation or hazard zone (see Installation

Procedures, “Safeguarding with Mechanical Guards”).

NOTE: For location of pylons in relation to the hazard area, refer to Appendix B: Regulations

and Guidelines, “Federal Register 1910.217 (c) (3) (iii) (e).”

Installation Procedures

Metal Box Controller Module

Resetting the MicroGuard

Error messages are stored in a nonvolatile memory

(EEPROM). To clear error messages, press the RESET

button. DO NOT hold in the button or hit it twice, just one hit. The unit will not reset until it is nished

displaying the entire error message.

If you remove power from the unit without clearing the error message, the message will reappear when you

power back up. Hit the RESET button to clear this error

from memory.

The RESET button is located inside the MicroGuard Controller Module on the door circuit board, left hand side, or the lower circuit board underneath the gray ribbon cable to start up the light curtain.

You can review all previous error messages recorded by holding down the RESET button while turning on the power to the unit, for two seconds. Each error message

will scroll by, last error rst. When you see the message “NO MORE CODES,” hit the RESET button to start up

the curtain. Up to 45 previous error messages can be displayed. You can shut down the curtain during normal operation by pressing the RESET button.

Installation Procedures

Metal Box Controller Module

Alignment Procedure

1) Both pylons should be placed so that they are mechanically aligned to one another. Make sure that both ends of each pylon line up with each other.

2) Slightly loosen the mounting bracket screws to allow for slight rotational movement of Receiver pylon.

3) Move the Receiver pylon to nd its midpoint (or

sweet spot) where the unit goes from RED to GREEN to RED.

4) Tighten the screws once you nd the midpoint

and repeat the operation for the Emitter pylon.

If you still cannot get the unit to go GREEN

5) Recheck mechanical alignment.

6) The diagnostics display will indicate the distance

(in inches) of the rst missing beam from the

connector end of the guard and the total number

of missing beams (i.e., 12 4 = rst missing beam

is 12” from connector and a total of 4 beams are

missing or 015A = rst missing beam is 1.5” from

connector and 10 beams are missing)

7) Loosen the mounting bracket corresponding to the end of the pylon closest to the missing beam and adjust it to get the unit to go GREEN.

If you are using mirrors, refer to Figure 3

8) Every mirror you use will increase the difculty of

alignment and will reduce the overall maximum optical distance you can achieve. A loss of 5% per mirror should be used to determine the total optical distance (i.e., 15’ through two mirrors =

16.5’ with losses).

9) You may have to rotate all mirrors in turn (starting

from the Emitter end) to nd the true optical path

of infrared light. Also, you may have to toe in one end of the mirror due to irregularities in the mirror brackets.

NOTE: Make sure you do not exceed the total

optical path distance of 20’ or the curtain distance

that was specied.

Operations

NOTE: Examine the MicroGuard on a daily basis to

make sure that no one has moved the light curtain pylons closer to the pinch point or removed any mechanical guards from around the curtain.

NOTE: If it is possible for someone to go through the

light curtain and remain in a dangerous area without having to block the light curtain, you must order the Resettable Latching Relays option which keeps the curtain RED even after you are no longer blocking the curtain. The Latchout reset button is mounted away from the dangerous area and must be cycled to reset the curtain.

1) Power up the light curtain. If a fault occurred the

last time the unit was powered and was never

RESET, it will appear as a “SLAVE FOUND” error

message and you will have to push the RESET button to clear the fault message and start the curtain.

2) When GREEN the curtain will display “RDY” or “rdy “ depending on any options that were set (see

Appendix A: Diagnostics and Troubleshooting for Descriptions).

3) When RED due to blockage, the display will

indicate the location of the rst obstruction(s) and the total size of the obstruction(s) (see Appendix

A: Diagnostics and Troubleshooting). If you have Floating Blank, then this is indicating that your

object is too large for the oating size you have selected. If you increase the Floating Blank size,

you must recalculate the safety distance formula since the object sensitivity will be larger. If you have the Resettable Latchout option, the display will show “PENT” to indicate penetration. You must cycle the Latchout RESET button to clear the curtain (see Optional Features, “Resettable

Latching Relays”).

6) Auto Blank. The display will show “AB” to indicate

that an object is programmed in and its size (in

beams) is shown as the next digit. If you keep

getting a “MOVE” message and your object is

not moving, try repositioning the object slightly (+/- 1/4”) and reprogram it back into memory. If you get a “SIZE” message, you must either get new software to allow a larger object or reduce

your object size.

7) Floating Blank. The display will show “FB” to

indicate the allowed blanking size in beams. Once

an object penetrates the curtain, any second

object will cause the curtain to display “OBST” to

indicate that a second obstruction is in the curtain. This is done in case you select a Floating Blank

size much larger than the actual object size.

4) When RED due to a fault, the display will scroll the error message that caused the fault and the board and beam number (if it can be pin pointed).

You must rst correct the fault and then push the

RESET button to clear the fault from memory, even powering down the unit will not clear the fault from memory (see Appendix A: Diagnostics

and Troubleshooting).

5) If you have the Guarding Mute-Out option, the

display will show “MUTE” during the up stroke. If you have the Cincinnati Interface hooked up, the display will show “CINN” during the up stroke

(see Optional Features, “Guarding Mute-Out”).

ANSI Standard B11.19-2003

Formula for calculating safety distance of light curtains from hazardous point of operation.

The effective sensing eld of the device shall be located at a distance from the nearest recognized hazards such that the operator or others cannot reach the hazard with

a hand or other body part before cessation of motion

during the hazardous portion of the machine cycle.

The point at which a device responds to an intrusion may vary. The devices should be located or adjusted such that the device always responds to the intrusion at or prior to the safety distance. Care should be exercised when installing the device to ensure that it does not detect false signals from other devices in the area.

Usually the electro-optical presence-sensing device is

used in a manner that provides a protected zone in front

of the primary work area with auxiliary devices or guards used to protect secondary access areas. In some cases, however, mirrors may be used in conjunction with the device to provide 2-, 3-, or 4-sided protection.

The machine stop time should be measured with the machine running at its fastest speed with its heaviest die or tooling and the stop time being measured at the 90° position in the downstroke.

When blanking features are used and when the

Object sensitivity = size of the blanked area plus

minimum object sensitivity without blanking.

Once this value is found, then determine Dpf.

If the entre blanked area is lled with mechanical

guarding or other xed material or guards, use the

Metal Box Controller Module

Safeguarding with Mechanical Guards

When a light system is used to protect the operator or passerby from penetration, it must be mounted and

properly sized (grid length) so it is impossible to reach under, around, or over into the hazardous point of operation zone. Infrared light systems normally guard

the front or feed area of a machine. The sides or the areas where the light screen does not guard must be guarded by some other means.

If the position of the safety light curtain will allow the operator or others to place themselves between the

sensing eld and the hazardous area, auxiliary guards or

devices such as safety mats, barrier guards, or devices should be used in conjunction with the safety light curtain to prevent the operator or others from exposure

to the hazardous area. If mechanical guards such as

polyurethane, expanded or perforated metal, hairpins, etc. are used to guard these areas, the opening must

comply with the OSHA safety distance in relationship

to the openings.

After installation of point of operation guards and before a job is released for operation, a check should be made to verify that the guard will prevent the operators hands

from reaching into the point of operation or any hazard zone.

Table 2 outlines the distances that guards should be

positioned from the nearest point-of-operation hazards.

The various openings are such that for average-sized hands, an operator’s ngers will not reach the point of

operation.

After installation of point-of-operation guards and before a job is released for operation, a check should be made to verify that the guard will prevent the operator’s hands or other body parts from reaching the point of operation.

Light Curtain Test Procedure

Use a dowel rod (or similar object) with a diameter

equal to the M.O.S. (Minimum Object Sensitivity) of

the guard you are testing. Move the rod through the

eld of the curtain (i.e. top to bottom for vertically

mounted curtains). Repeat this test close to the Emitter pylon, close to the Receiver pylon, in the middle between the pylons, and most importantly in front of the operator position.

Make sure the curtain indicates a “Blocked” condition

(RED light) when the rod is in the eld of the curtain.

Check and make sure the machine cannot move when the curtain shows “Blocked”. If the machine can operate while the curtain shows a “Blocked” condition, then re-examine your wiring.

NOTE: Always use both safety relays in your STOP

circuit(s).

If the curtain does not show “Blocked” when the rod

is in the eld: Check to make sure the rod is truly in the curtain’s eld, and re-check the curtain’s Minimum Object Sensitity (including AutoBlank and Floating blank options that change the M.O.S.).

Infrared light from the curtain may be reecting around the rod due to reective material too close to the curtain’s eld. In this case, you will have to move the curtain pylons back away from the reective

material and repeat the test over again. The curtain’s power level can also be reduced by the factory.

Diagnostics and Troubleshooting

Obstruction or Misalignment

When the curtain is obstructed or misaligned, the display will present four numbers to indicate location of obstruction or misalignment.

Distance

The rst three numbers displayed represent (in inches) the rst obstructed or misaligned beam on the guard

starting from the cable end of the pylon. The third digit is blank for whole inches and “5” for half inches.

Total #

The last digit indicates the total number of beams

blocked or misaligned. The digit counts in Hexadecimal

(0 to F = 0 to 15 beams). A “>” sign indicates more than 15 beams missing.

“A”=10 beams, “B”=11 beams, “C”=12 beams, “D”=13 beams, “E”=14 beams, “F”=15 beams

Computing Object Size

To compute an object’s size, use the following formula: size(inches) = TOTAL# x 0.5”

This can be used to evaluate an object’s size up to 7.5”

in diameter.

(i.e., TOTAL# = 3 so SIZE = 1.5”)

Error Conditions

When an ERROR message is displayed, the end of the

message will display a set of numbers to indicate where along the pylon the problem resides.

The rst two numbers displayed represent the rst

problem beam on the guard starting from the cable end of the pylon. The third number represents the total number of beams blocked on the guard. Boards inside each pylon are exactly four inches long. Using this you can determine which board in the pylon is bad.

Denitions

BOARD #: Indicates rst board on which a problem

was detected (01 to 17).

(i.e., 01 = board nearest cable connection)

BEAM #: Indicates rst problem beam on the board

AutoBlank data corrupted

The number of beams found blocked during programming is no longer equal to the number found in memory. This may indicate that the object moved just as it was being programmed in memory.

CPU clock failure

MASTER has a bad on-board clock circuit in the CPU.

Emitter ring at wrong time xxy

An LED in the Emitter pylon was ring even

though it was not told to do so. Could be a short circuit in the emitter pylon or a faulty circuit on the computer board.

Emitter length fault xxy

The length of the Emitter pylon was detected as different from the jumpers S3 set on the door of the Controller Module. xx indicates board number in 4” increments from circular connector; y indicates beam number of that board (1 to 8). Check for a disconnected cable, missing jumper in the pylon, or a faulty circuit on the computer board.

External contact short

External relay checking option has detected that the external contact did not close during a cycling of the curtain from GREEN to RED. Second relay is able to shut down the system.

External contact welded or wire cut

External relay checking option has detected that the external contact did not open within .25sec of the curtain going RED. Second relay is able to shut down the system.

External infrared source detected xxy

Whenever the curtain is RED (at power up) the unit checks for external sources of infrared that might interfer with normal operation of the curtain. xx indicates board number in 4” increments from circular connector; y indicates beam number of that board (1 to 8). This could also indicate that the detector circuit is faulty.

FLIP

MASTER microprocessor is getting intermittent blockage of the curtain due to weak signals and

is ip-opping between GREEN and RED. Re-

align the pylons.

Illegal code

MASTER has come across an illegal machine

language code inside the ROM of the CPU (this

could indicate a bad CPU chip).

Improper operation

MASTER has determined that there has been an improper operation in the CPU and has reset for safety.

Initializing memory

The SLAVE has determined that the EEPROM

memory chip does not contain the proper setup

values and will attempt to initialize it. This message should only occur during the rst time

power up. If you get this any other time, it could mean a faulty memory chip or a glitch in the power.

Internal relay bad/missing

One of the Internal relays has a contact that is not

open or closed and is determined to be missing. Check for faulty relay contacts or relay position circuitry.

Internal relay is not energizing

Internal relay was told to turn but the contact never closed. Check for a faulty relay or a faulty driver circuit.

Internal relay is stuck on

Internal relay contact has not opened up when requested to do so. Check for a faulty relay, welded contact, or a faulty driver circuit. Second relay is able to shut down the system.

MBLK

MASTER has detected that the pulse width coming from all the receivers is too wide and has determined that the pylons are too close together ( < 1’ ). Turn the pylons away from each other slightly.

A-3

Appendix “A”

Diagnostics and Troubleshooting

Mute-out switch fault

The proper sequence of limit switch closures was not correct and so the unit shut down. This could also be due to excessive noise getting into the PLC lines causing misinformation.

No ACK from memory

The SLAVE is requesting error messages from the EEPROM memory chip but has not received

an acknowledge from it within the time allotted.

No clock line detected

SLAVE microprocessor could not detect this

signal line from the MASTER during a normal scan of the curtain. Check for a faulty circuit in the computer board.

No data line detected

SLAVE microprocessor could not detect this

signal line from the MASTER during a normal scan of the curtain. Check for a faulty circuit in the computer board.

No emitter line detected

SLAVE microprocessor could not detect this signal

line from the MASTER during a normal scan of the curtain. Faulty circuit in the computer board.

No more error codes

This message appears after the control unit is

nished displaying all previously recorded error

messages stored in memory. You can start up the curtain by pushing the RESET button when you see this message.

Open LED in emitter pylon xxy

An LED in Emitter pylon was found not ring. xx

indicates board number in 4” increments from circular connector; y indicates beam number of that particular board (1 to 8). Could also be a faulty cable, computer board, or R27 on the computer board has burned open.

Power failure reset

SLAVE has reset due to either a power loss or some condition that caused the SLAVE to lockup,

in which case the watchdog reset it.

RAM failure

MASTER OR SLAVE has determined that their

internal RAM cannot hold data correctly. Glitch in power can cause this.

Receiver length fault xxy

The length of the Receiver pylon was detected as different from the jumpers S3 set on the door of the Controller Module. xx indicates board number in 4” increments from circular connector; y indicates beam number of that board (1 to 8). This could be a cable pulled out, missing jumper in the pylon, faulty circuit on the computer board.

Receiver Oscillating xxy

More than one pulse was detected during reception of the proper Infrared signal. x x indicates board number in 4” increments from circular connector; y indicates beam number of that board (1 to 8). This may indicate that the detector circuit has a problem or a severe external infrared problem was detected.

Reset held down

You have held the reset button down too long.

The SLAVE is trying to communicate with the EEPROM memory chip.

SBLK

SLAVE microprocessor detected blockage when

the MASTER did not. Some of the receiver signals are so weak that the leading edge of the pulse is

missed by the SLAVE but the trailing edge is not

missed by the MASTER. Re-align the pylons.

Serial data corrupted

The MASTER has requested data from the SLAVE

but the check-sum value received does not match the value calculated from the data received.

1) Check for electrical noise. Add MOV’s from

each leg of safety relay output to earth ground.

2) Receiver pylon may be seeing an Emitter pylon of a different light curtain. 3) Possibly a faulty computer board or connection.

Serial data transfer incomplete

The MASTER has requested data from the SLAVE and the SLAVE has not responded within the

allotted time. This can happen if you hold the RESET button down at the wrong time.

Short LED in emitter pylon xxy

An LED in Emitter pylon was found not ring. xx

indicates board number in 4” increments from circular connector; y indicates beam number of that board (1 to 8). Could also be a faulty cable, computer board, or R44 (R27 below Rev 5) on the computer board has burned short.

A-4

Slave Found

SLAVE microprocessor has sent an error code

to the MASTER and the MASTER is displaying it. Any one the following error messages can

also be sent by the SLAVE. Also, you see this message when the SLAVE is sending back error

codes from the memory chip during the power up reset sequence.

UNKNOWN CODE

The MASTER has received an error code from

the SLAVE for which it has no match. It is possible

that the software versions don’t match.

Waiting for reset button

Master is waiting for user to push the RESET button to start scanning. This indicates that you pushed the RESET button too soon after getting

an error message and prevented the SLAVE from

saving the error code in permanent memory. You should wait until the message displays one time before pushing the RESET button.

Safety Guidelines for Management

Operational Safety

1. Appoint a Safety Coordinator to be responsible for safety regulations, requirements, and suggestions.

He must review and investigate all accidents and

“close calls.”

2. Establish and issue safety rules. Inform each employee of his responsibilities. Make sure he understands them and knows what is expected of him.

3. A thorough review and an early inspection must be made of existing presses, dies, and point of operation guarding to attain the degree of responsibility required by ANSI B11.1-1988 Safety Standards and Federal State laws. Review what

mandatory modications are necessary.

4. Equipment that is no longer safe and that cannot be economically upgraded should be destroyed.

5. Never allow persons legally under age to operate or assist in the operation of machinery.

6. All personnel must be properly trained to eliminate accidents and injuries.

7. Regardless of the operator’s experience, education, or language barrier, it is the responsibility of the supervisor to give him a thorough explanation with each new job assignment.

8. No employee should be given a work assignment

that he does not fully understand. Only properly

instructed and thoroughly trained personnel should be assigned to work on or with any machine.

9. It shall be the responsibility of the employer to provide an adequate, clean, safe, and uncluttered work area around each machine.

10. If a malfunction is reported, stop the machine immediately, correct the problem, then resume production.

11. Investigate all accidents and close calls.

Analyze the reason for occurrence. Take action

to prevent recurrence. Keep records of the investigation and preventative steps that were taken.

12. Only employees who understand the machines,

operation and safety requirements, and who are able to communicate this knowledge should be given the responsibility of instructing and training others to perform as operators.

13. Management must decide that personnel protective safety equipment is requi red to perform each job safely. Items such as safety glasses, shoes, gloves, helmets, hand pads, spats, protective sleeves and material handling equipment are common in the metal working industry. If noise levels are excessive, protective headsets and earmuffs are recommended.

14. When designing point of operation guarding, the manufacturing process should be weighed heavily in favor of operational safety.

15. Establish safe and convenient material handling methods and procedures.

16. Post in convenient areas the names, addresses, and phone numbers of physicians and hospitals,

and members of the organization who are to be

called in case of emergency.

17. All equipment must be electrically connected according to the National Electric Code and be consistent with other accepted practices.

18. Provide adequate and proper re protection

equipment.

Power Press Guarding

1. Press manufacturers do not know and cannot foresee the magnitude of potential applications of power presses. Therefore, only the press user can determine the type of guards that have to be used in order to perform the job safely. It is the responsibility of the user management to make certain that point of operation guarding and other necessary safety devices are installed. The press should be guarded in such a manner that it is impossible for the operators to place their hands or any other part of the body in the die area.

B-2

Appendix “B”

Regulations and Guidelines

2. The press user should become thoroughly acquainted with the safety devices commonly employed in power press operations.

3. Feeding devices are strongly recommended, since they remove the operator from the die area,

and therefore allow more effective utilization of

guards and safety devices.

4. Do not release a press for production before installing and testing all guards and covers.

5. Make frequent evaluation checks of all guarding and devices while the press is running. Correct

all unsafe ndings immediately.

Power Press Care through Inspection and Maintenance

1. All maintenance and inspection personnel should

be specically instructed, and must understand

proper maintenance and inspection procedures contained in this manual.

2. Set up a daily, weekly, and monthly press inspection program. Use a checklist and verify that the job is done correctly.

analyzed in order to take corrective action.

Supervisor Training

It should be the responsibility of management to instruct their supervisors on safety, giving job instructions, supervising operators, determining accident causes, and building safety attitudes among the machine operators. Accidents can occur due to inadequate training of supervisors.

Operator Training

It shall be the responsibility of management to insure

proper training of operators. A specic training program

should be instituted to instruct the operator in safety, proper usage of the equipment, and correct operational procedure in performing each and every job. In addition to the supervisor, the operator should be familiar with the proper guarding of the point of operation. Never permit an operator to start a job without complete instructions from his immediate supervisor.

3. Establish a preventative maintenance program. Records of all maintenance work performed must be kept.

4. Since all equipment has a limited life, quality maintenance personnel are required to obtain maximum usage of your equipment.

5. Releasing a power press for production following maintenance should be the responsibility of a

qualied individual assigned by management.

6. To maintain the original level of press reliability, careful inspection of mechanical, electrical, and pneumatic areas must be made. This may give

an advance warning of a hazard which then can

be corrected to prevent possible injuries and damage.

Safety Enforcement

In or der to have a n effec tiv e sa fet y pr ogr am, management at all levels must enforce every safety rule and regulation. Strong disciplinary measures are sometimes required. They should consist of a warning, written reprimand, work suspension, transfer, demotion, or possibly a dismissal. All infractions must be reported

and recorded. Once an infraction in noted, it shows

that an unsafe practice or condition has existed. This may be the result of poor planning or improper training and instructing. The reason for the infraction should be

Proper power up example: SEMF0P <CR> 10 lines of EEPROM memory <CR> GA0024m (for a 24 beam length guard)

Blocked Beam pattern display: If you transmit the ASCII character ‘B’ via the USB port, the Microguard will return a string of ASCII character 1’s and 0’s based on the beam blockage. The start of the string represents the beam closest to the cable end, and the end of the string is represented

by the ASCII character ‘@’

0 = clear beam 1 = blocked beam

Example for an MG-04-0F-20 model (which has a total of 8 beams):

Send ‘B’, then you Receive 01100000@

This indicates 2 blocked beams (2nd and 3rd beams from the cable end)
