WARNING! Read and understand this section prior to installing a 4700 system.
A 4700 system is a general purpose presence sensing device designed to guard personnel working
around moving machinery.
Whether a specific machine application and light curtain installation complies with safety regulations
depends on the proper application, installation, maintenance and operation of the light curtain. These
items are the responsibility of the purchaser, installer and employer.
The employer is responsible for the selection and training of personnel to properly install, operate, and
maintain the machine and its safeguarding systems. A 4700 system should only be installed, verified
and maintained by a qualified person. A qualified person is defined as “a person or persons who, by
possession of a recognized degree or certificate of professional training, or who, by extensive
knowledge, training or experience, has successfully demonstrated the ability to solve problems relating
to the subject matter and work.” (ANSI B30.2-1983)
To use a 4700 series safety light curtain the following requirements must be met:
— The guarded machine must be able to stop anywhere in its cycle. Do not use a safety light curtain on
a press with a full-revolution clutch.
— The guarded machine must not present a hazard from flying parts.
— The guarded machine must have a consistent stopping time and adequate control mechanisms.
— Severe smoke, particulate matter and corrosives may degrade the efficiency of a safety light curtain.
Do not use a 4700 system in this type of environment.
— All applicable governmental and local rules, codes, and regulations must be satisfied. This is the
employer’s responsibility.
— All safety-related machine control elements must be designed so that a alarm in the control logic or
failure of the control circuit does not lead to a failure to danger.
— Additional guarding may be required for access to dangerous areas not covered by the 4700 series
system.
— Perform the OMRON STI test procedure at installation and after maintenance, adjustment, repair or
modification to the machine controls, tooling, dies or machine, or the 4700 series system.
— Perform only the test and repair procedures outlined in this manual.
— Follow all procedures in this manual for proper operation of the 4700 series system.
The enforcement of these requirements is beyond the control of OMRON STI. The employer has the
sole responsibility to follow the preceding requirements and any other procedures, conditions and
requirements specific to his machinery.

WARNING! Despite inherent safe design measures, safeguarding and complementary
protective measures adopted by the user, residual risk may remain in any installation. Potential
risks are strictly under the control of the end user and may include severe injury or death.

4 S YSTEM O PERATION 4
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 required. Typical applications
include mechanical power presses, robotic work cells, filter presses, injection molders, food
processing equipment and automated assembly equipment.
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 Section 7 on page 27. The protected
machine is allowed to operate. Pressing and releasing the start button has no effect.
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 Section 7 on page 27. The
protected machine is not allowed to operate. Press and releasing the start switch has no effect.
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

from machine run to machine stop and remain in this state until the obstruction is removed. Once the
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 self-
tests. 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.
NOTE! The definitions above mention a start switch. See Section 10–“Connecting to the Machine
Control Circuit” for wiring of the start switch.

4.3 OPERATING MODE SELECTION
Operating mode is selected by setting positions 1 and 2 of Switches A and B, located under the
controller cover. Refer to Table 4-1. Any mismatch between the settings of Switch A and B will result
in an alarm condition. In addition, if the configuration switch settings change while the system is on, it
will enter the alarm state with the safety outputs off.

4.4 START SWITCH TYPE SELECTION
The type of Start switch (Normally Open or Normally Closed) used by the 4700 system is selectable
by a jumper located under the controller cover. Refer to Figure 3-4 DIN Controller Components and
Figure 3-5 Metal Chassis Controller Components. Placing the jumper between Pins 1 and 2 of JMP 1
selects a Normally Closed Start Switch. Placing the jumper between 2 and 3 selects a Normally Open
Start switch.
Note: If there is a mismatch between the type of Start selected and used, (i.e. jumper between Pins 1
and 2 and Normally Open Start Switch used) the switch must be pressed and released twice before
the system will enter a Run state.

Warning! Use of Exact Channel Select and/or Floating Blanking will make the 4700 system less sensitive to
objects in the detection zone. Improper use of either can result in severe injury to personnel. Exact Channel
Select may require a hard barrier guard (see Section 5.8 Additional Guarding When Using Exact Channel
Select), Exact Channel Select or Floating Blanking requires an increase in the safety distance. Read the
following section carefully.
- To prevent unauthorized modification of the detection zone. The system controller should be installed in an
enclosure with supervisor-controlled access.
- If the object to be ignored by the Channel Selected beams does not completely prevent access to the hazardous
area, then either use a hard guard or other means to block access or increase the minimum safe distance as
required by the proper formula.
- Any beams which are not in alignment at the time of Channel Select programming may be inadvertently
deselected. Use the OMRON STI Test Procedure to verify the correct configuration.
- Floating Blanking increases the minimum safety distance therefore test object size will increase.
- After programming or activating Channel Select or Floating Blanking, to avoid unexpected areas where the
system may not sense an intrusion into the detection zone, use a proper size test object to perform the OMRON
STI Test Procedure.
