The 4700 system is a microprocessor-controlled, infrared transmitted-beam safety light curtain. The
system consists of a receiver assembly and a transmitter assembly. Quick disconnect cables link the
controller to the transmitter and receiver.
The safety light curtain is often used where personnel protection is

4.1 OPERATING STATES
The operating condition of a 4700 system is described in terms of states. The following operating
states exist for the 4700 system.
4.1.1 MACHINE RUN
The two system safety outputs are in the ON state, the green machine run indicator is lit, and the
auxiliary output is in a state consistent with its configuration. See
machine is allowed to operate. Pressing and releasing the start button
4.1.2 MACHINE STOP
The two system safety outputs are in the OFF state, the red machine stop indicator is lit, and the
auxiliary output is in a state consistent with its configuration. See section

ations
4.1.3 INTERLOCK
The two system safety outputs are in the OFF state, the red machine stop indicator and yellow
interlock indicator are lit. The auxiliary output is in a state consistent with its configuration. See
Section 7 on page 27. The interlock state does not allow the protected machine to operate until the
detection zone is clear of obstructions and the start button is pressed and released.
4.1.4 ALARM
The two system safety outputs are in the OFF state, the red machine stop indicator is lit, the yellow
interlock indicator is flashing, and the auxiliary output is in the OFF state. The alarm state does not
allow the protected machine to operate. The primary difference between alarm and interlock is that the
4700 system will remain in the alarm state until power is recycled or the start switch is pressed and
released and the system has run a self-test.
4.2 OPERATING MODES
System operating modes determine the start-up and operating behavior of the 4700 system. Operating
mode definitions rely on the operating states presented above. Operating mode selection is performed
via configuration switches under the front cover of the controller.
NOTE! If internal faults are detected by the 4700 system during power-up or operation, it will enter
the alarm state with its safety outputs in the OFF state.
4.2.1 AUTOMATIC START
The 4700 system will power-up with its safety outputs OFF, and perform system initialization and self
tests. The 4700 system will enter the machine run state if no obstructions are present in the detection
zone. In this state, when an object is sensed entering the detection zone, the 4700 system will change

detection zone is clear, the 4700 system will automatically change from machine stop to machine run.
4.2.2 START INTERLOCK
The 4700 system will power-up with its safety outputs OFF and perform system initialization and selftests. If no obstructions are detected in the protected zone, (or an exact channel select pattern satisfied),
the 4700 system enters the interlock state. To enter the machine run state, the detection zone must be
clear (or an exact channel select pattern satisfied), and then the operator must press and release the start
switch. In the machine run state, when an object is sensed entering the detection zone the 4700 system
will change from machine run to machine stop. Once the detection zone is clear, the 4700 system will
automatically change from machine stop to machine run.
4.2.3 START/RESTART INTERLOCK
The 4700 system will power-up with its safety outputs OFF, and, if no faults are detected, enter the
interlock state. To enter the machine run state, the detection zone must be clear (or an exact channel
select pattern satisfied), and then the operator must press and release the start switch. In the machine
run state, when an object is sensed entering the detection zone the 4700 will change from machine run
to interlock. The 4700 system will remain in the interlock state even after the obstruction is removed
from the detection zone. To enter the machine run state, the operator must press and release the start
switch. If any obstruction is present in the detection zone when the start switch is pressed and released,
the 4700 will remain in the interlock state.

System Response
ECS requires that any portion of the detection zone which is block
ed remain blocked
. If the obstruction
is removed the 4700 system will enter a machine stop state. When selecting channels to be masked, one
channel must remain unblocked. A channel is defined as one transmitter/receiver pair or “beam”.
See Table 5-1, System Response to Exact Channel Select for a diagram of 4700 system response during
operation with ECS active.
MCS stores up to four patterns of selected beams. Just as the ECS disables selected, fixed areas of the
detection zone by masking off specific, fixed beam locations, the MCS can be programmed to store
four different patterns. MCS is helpful when a machine requires multiple setups where stationary
objects such as tooling, fixtures, or material frequently obstruct a portion of the detection zone. Access
and programming is performed using a PLC or switch inputs. The suggested logic patterns for
identification of the stored program are in Table 5-2 on page 20. Refer to drawings Figure 5-1 andFigure 5-2 for connection recommendations.

Warning! Using Exact Channel Select with Floating Blanking is an advanced feature. All situations which
may occur to the 4700 system detection zone must be carefully considered.
objects in the detection zone. The safety distance must be increased. Failure to do so may cause serious injury.
When both Exact Channel Select and Floating Blanking are selected, the floating channels are allowed
to occur anywhere within the detection zone, even within the area selected by Exact Channel Select. In
these areas, a channel that should normally be blocked is allowed to be clear.
When Exact Channel Select and/or Floating Blanking is active, the safety distance is affected. Exact
Channel Select and Floating Blanking desensitize the light curtain and increase the size of the
minimum object detected. The increase is equal to the channel spacing distance for each channel that is
disabled.
• A 4700 system with 12 mm minimum object resolution and one channel disabled has a minimum object
sensitivity of:

5.5 A CTIVATINGAND PROGRAMMING EXACT CHANNEL SELECT
Warning! To prevent unauthorized modification of the sense field, the system controller should be installed in
an enclosure with supervisor-controlled access.
Exact Channel Select is activated by setting position 4 of Switches A and B, located under the
controller cover. Refer to Figure 3-1. Any mismatch between the settings of the switches will result in
a alarm condition.
To program an ECS pattern, the 4700 system must be in the machine stop state. An ECS pattern is
stored
by blocking th
e appropriate area of the detection zone and pressing, then releasing the program
button (See Figure 3-4 and Figure 3-5 for locations). The MCS works the same as the ECS except in
addition to blocking the appropriate area of the detection
zone, an four position binary
switch or PLC

will result in an alarm condition. Use of the program button is not required.
5.8 ADDITIONAL GUARDING WHEN USING EXACT CHANNEL SELECT
Exact Channel Select creates “holes” in the detection zone. These “holes” are required for certain
applications. If an obstruction does not completely fill these “holes” one of two actions will need to
happen: (Refer to Figure 5-3 Adding Hard guarding
1. The safe mounting distance will need to be increased to account for the larger opening in the curtain.
2. The area not filled by an obstruction must be guarded, typically by some method of hard guarding.

6.2 I NDIVIDUAL BEAM INDICATORS
The 4700 system has a visible, red Individual Beam Indicator (IBI), adjacent to each infrared beam.
These IBI’s are located on the receiver. The IBI will light when the infrared beam fails to meet the
conditions necessary for the 4700 system to remain in the machine run state.

6.3 MACHINE PRIMARY CONTROL ELEMENT (MPCE) MONITORING
MPCE monitoring is an important safety function. It monitors the 4700 system interface to the guarded
machine and checks to ensure that the control elements are responding correctly to the light curtain and
to detect any inconsistency between the two machine MPCE.
Connections for MPCE monitoring are made at the controller on terminals 10 and 11 for the DIN
c
ontroller and on TB7 te
Section 10 Connecting To The Machine Control Circuit. On power-up, the 4700 system looks for an
MPCE
closed condition. If this is found, it will enter a state consistent with the sele
mode. When the 4700 system enables its safety outputs, it monitors the MPCE for a closed-to-open
transition. This transition must occur within 300 ms or the 4700 system considers the MPCE faulted.
The 4700 system will then enter an alarm state. Additionally, if the MPCE connections are incorrectly
wired, the 4700 will enter an alarm state.
Upon entering a machine stop state, the MPCE input must close within 300 ms of the safety output

8.1 US SAFE DISTANCE FORMULAS
In the United States two formulas exist to properly determine the safety distance. STI recommends the
formula provided by the American National Standards Institute (ANSI) which incorporates additional
factors when compared to the formula required by OSHA.
The ANSI formula given below is for a normal approach to the light curtain.
D
= K x (Ts + Tc + Tr + Tbm) + D

Where:
= minimum safety distance, in inches, between the 4700 system detection zone and the nearest point

K =
hand speed constant in inches per second. The ANSI standard value is 63 inches/second which
assumes the operator starts a hand motion
B11.19-1990, “The value of the hand speed constant, K, has been determined by various studies and
although these studies indicate speeds of 63 in./sec. to over 100 in./sec., they are not considered
conclusive determinations. The user should consider all factors, including the physical ability of the
operator, when determining the value of K to be used.”

d = the minimum object detection of the 4700 in millimeters.

t1 = response time of the safety light curtain in seconds. This response time is given in Table 14-1,

t2 = maximum stopping time of the machine is seconds.
C = 850 mm.
i.e.:
S = (1600 mm/s x T) + 850 mm
8.2.3 FACTORS AFFECTING THE SAFETY DISTANCE FORMULA
When light curtains are used for machine initiation, their minimum object resolution must be 30 mm or
smaller (based on EN999, other standards may vary). In this case the formula given in 8.2.1 Safety
Distance Formula
for Systems with a Minimum Object Resolution of 40 mm or Less applies except that
the minimum distance S shall be greater than 150 mm. For parallel approach the formula C becomes:
C = 1200mm – (0.4 x H), but not less than 850 mm.
H = the height of the detection zone above the floor in mm.

9.2.2 CABLE CONNECTIONS
Transmitter and receiver connections are made at terminal positions 23 through 34. Insert and secure
the appropriate color conductor in the numbered position. Positions 26, 27, and 28 accept identically
colored conductors from both the transmitter and receiver. For ease of installation, the terminal block

STI recommends overlapping the light curtains in
order to have better coverage.
When two or more 4700 systems are mounted in close proximity and in alignment with each other,
precautions should be taken to avoid one curtain interfering with another. This can be corrected by
mounting the transmitters and receivers back-to-back or stacked. See Figure 9-7 for reference.
The 4700 detection zone is delineated by the inside edge of the transmitter and receiver endcaps. The
area outside these marks is not protected. Position the 4700 so that it is only possible to access the
danger point through the detection zone.
9.3.4 MARKING MINIMUM OBJECT RESOLUTION
Serial number labels on the transmitter and receiver indicate three possible minimum object
resolutions. During installation, use a permanent marker to obscure the object resolutions not set. This
will depend on whether no floating blanking, 1-beam or 2-beam floating blanking is set. See
on page 23 for information.
9.3.5 ALIGNMENT
Physical alignment of the transmitter and receiver units is easiest when the 4700 system is in the
automatic start operating mode with Exact Channel Select inactive. The units should be in the same
plane and at equal height.

ils.
• DIN controller and DC metal chassis controller:
The 4700 system operates directly from 24 VDC ± 20%, 2.25A*. Power to the 4700 system must come
from a dedicated power supply which must meet the requirements of IEC60204-1 and IEC 61496-1,
STI part number 42992 or equivalent. The 4700 system internally generates voltages for its own use.
No other devices should be connected to these voltages.
*Internal consumption of power by the controller is less than 10 watts (415mA)
• AC metal chassis controller:
100 - 230 VAC @ 30 VA.
9.3.7 SPECIAL REQUIREMENTSFOR PERIMETER GUARDING
In perimeter guarding applications the 4700 detection zone is placed around the outside perimeter of a
guarded machine or robot. This placement leaves space for personnel to stand between the detection
zone and the hazardous machine.
In this case, the guarded machine must only be restarted using a switch located outside and with a full
vie
of the area of hazardous motion. Operation of the 4700 system in the start/restart interlock
w
operating mode is suitable for perimeter guarding.
9.3.8 PRESENCE SENSING DEVICE INITIATION
Using the light curtain to initiate a machine after an object is removed from the sensing area is called
Presence Sensing Device Initiation (PSDI). Use of PSDI places additional requirements on the
guarding and safety controls. It can restrict advanced light curtain features such as Floating Blanking
and Exact Channel Select. Contact OMRON STI for further information. Good sources of reference for
PSDI include: ANSI RIA 15.06-1999, OSHA 1910.217(h), and ANSI B11.2-1995.

4700 system should not depend on a PLC to stop a guarded machine.
However, safety related monitoring devices are now available. See Figure 10-1 for connection to such
a device. Note that all safety inputs are directed to the monitoring device which also performs the

The MCF and MCJ can have up to four segments. It is possible for each segment to have a different
minimum object resolution.
Step 1: Determine the number of beams in each segment using Table 14-1, Table 14-2 and Table 14-
3.**
Step 2: Use the formula below to determine response time:
(Total number of beams x 0.0924) + 5.21 msec = response time in msec.
**The total number of beams in a system cannot exceed 192.
MCF4700 example:
MCF47-12200-301800-20300
The unit has three segments, a 12 mm resolution of 200 mm length, a 30 mm resolution of 1800 length
and a 20
Table 14-1 show 32 beams for the 12 mm segment, Table 14-3 show 84 beams for the 30 mm segment
and Table 14-2 shows 28 beams for the 20 mm segment. The total number of beams is:
mm resolution
of 300 mm length.
32 + 84 + 28 = 144.
From the formula:
(144 beams x 0.0924) + 5.21 ms = 18.5 ms.

It is possible to assemble the joints in either a 90 or 270-degree orientation. Prior to assembling the
sensor, verify the desired configuration of the segments. Power must not be connected during
assembly. Ensure that receiver segments are mounted to receiver segments, and transmitters are
mounted to transmitter segments. The receiver first segment has a red connector on the cable, and the
other receiver segments are identified with a “R” on the joint. Transmitters are identified with a “T”.

After the unit is assembled in the desired configuration, measure the mounting holes on the configured
system. Confirm these dimensions by using the drawing Figure 14-2 & Figure 14-4. The mounting
holes should match within a reasonable tolerance. Use the dimensions from the drawing for proper
alignment.
The first segment is the segment which connects to the power supply/controller. Make sure the first
transmitter
is mounted dire
ctly across from the first receiver segment. This orientation must continue
with all of the remaining segments. The transmitter and receiver segments must be installed parallel to
and in line with each other.
14.4.5 MINIMUM OBJECT RESOLUTIONAT JOINTS
To make maximum use of the detection zone’s minimum object resolution, it may be necessary to
place suitable hard guarding between jointed corners in order to prevent unguarded access.

connectors are used to connect this communication system together. Our LCM-2XX series controllers
use the M12 micro-style connectors conforming to the DeviceNet standard.
The following internal connections are in compliance with the electrical requirements of the DeviceNet
standard however, the internal connections of these Nema controllers do not follow the wire insulation
color code as outlined by that standard.
When using the Nema type enclosure the internal DeviceNet Interface (Daughter Board) is connected
to a pre-m
anufactured 5-wire
The M12 male connector as shown in figure 2, provides the external connection for the network.

OMRON STI provides a 5-pin Phoenix-style connector for the LCM-2 controller.
. . . . .
The MC4700 includes a reference to this connection in its manual in section 3, figure
3-4. The
connections are also shown in figures 10-2 and 10-3.
The following figure illustrates the wire insulation colors and pin outs for the screw connectors on the
LCM-2 Din module.
Note:
The DeviceNet wiring pin out for the LCM-2 is the opposite or mirror image of the DeviceNet
standard so, a standa
rd network connection may have to be re-wired for this controller.

C.5 D EVICENET CONFIGURATION SWITCHES
To accommodate DeviceNet configuration switches the LCM-2 (DIN version only) has DIP switches
located near the bottom of the Power/Device-Net board. This board is located on the top side of the
DIN module and looks similar to figure 1.
Figure C-5 LCM-2 Power/DeviceNet board
These DIP switches can be used to set the Device-Net Baud Rate and Node number on the LCM-2
controller. When all of the switches are set to “1” or “ON” the LCM-2 is programmable via software
using a dedicated Device-Net configuration tool. When the DIP switches are used to set the Device-Net
configuration, use the following table to define the Baud Rate and the Node number. Note: The Node
