OPERATING MANUAL PSEN op4F/H-A series 1 GENERAL INFORMATION 1.1 General description 1.1.1 General description of the safety light curtain The safety light curtains in the PSEN op4F/H-A series are multibeam active optoelectronic protective devices for work areas in which machines, robots and automated plants in general could endanger the physical integrity of operators who could come into contact with moving parts, even if only by chance.
PSEN op4F/H-A series OPERATING MANUAL This manual contains all the information you need to select and operate the protective devices. Specialised knowledge of safety issues is required to integrate a safety light curtain correctly in a plant. PILZ’s technical customer service team is available to provide any information you need regarding the functionality of the PSEN op4F/H-A safety light curtains and the safety regulations concerning correct installation. 1.1.
OPERATING MANUAL PSEN op4F/H-A series 1.2 Guidelines for selecting the protective device Once the hazards have been assessed appropriately, there are at least three essential features to consider when selecting a safety light curtain: 1.2.1 Resolution The device’s resolution is understood to be the minimum size that an opaque object must be to safely interrupt at least one of the beams that form the area of the protected field.
PSEN op4F/H-A series 1.2.2 OPERATING MANUAL Height of protected field The height of the protected field is understood to be the height protected by the safety light curtain. Fig. 2 – Height of protected field 1 2 = = 3 = Protected field Height of protected field Operating range The height monitored by the PSEN op4F/H-A corresponds to the overall height of the light curtain. With reference to the previous diagram, the height of the protected field can be taken from the table below.

OPERATING MANUAL PSEN op4F/H-A series Application examples This example is based on a light curtain with a height = 600 mm. To calculate the distance of the device from the light curtain in a vertical position, the following formula is applied: S = K*T + C Therefore: T = t1 + t 2 t1 = Response time of light curtain + release time of relay (specific time of PNOZ S3: 20ms) With a reaction time of the light curtain of 15 ms the result is a max.
PSEN op4F/H-A series OPERATING MANUAL 1.3 Typical application areas Example 1: Protecting the operating area on drilling machines The operator inserts the workpiece and removes it after machining. The operator must be protected from injury during the machining process. Solution: The safety light curtain PSEN op4F/H-A is particularly suitable for this application, as the device needs to be installed directly on the machine.
OPERATING MANUAL PSEN op4F/H-A series Example 4: Moulding machine The moulding machine is used to create complex shapes from metallic parts or parts made from other materials. In this case it is necessary to prevent the operator’s hands or other limbs being dragged, entangled or cut by the tool itself or being injured by the spindle.
PSEN op4F/H-A series OPERATING MANUAL 2 INSTALLATION 2.1 Precautions to be taken during selection and installation of a light curtain Ensure that the safety level guaranteed by the PSEN op4F/H-A (Type 4) complies with the actual risk assessment of the machine to be monitored, as well as the level defined by the standard EN ISO 13849. Ensure that the light curtain’s outputs (OSSD) are used as machine stopping devices and not as control devices. The machine must have a separate START control.
PSEN op4F/H-A series OPERATING MANUAL 2.2 General information on positioning the device Special care should be taken when positioning the safety light curtain to ensure it provides efficient protection. The device must be installed so that the danger zone cannot be accessed without interrupting the protected field. Fig. 5 shows some possibilities for accessing the machine from above and below. Situations like this could turn out to be extremely dangerous.
PSEN op4F/H-A series OPERATING MANUAL NO YES Fig. 7 2.2.1 Fig. 8 Minimum distance from reflective surfaces Reflective surfaces close to the beams emitted from the protective device (whether from above, below or from the side) can cause passive reflections. These passive reflections can adversely affect how the object is detected within the protected area.
PSEN op4F/H-A series OPERATING MANUAL This minimum distance depends on the following factors: • The distance between the transmitter (TX) and receiver (RX) • The actual opening angle of the light curtain; in particular: when Type 4 light curtain = 5° (α = ± 2.5°) The illustration in Fig. 10 shows the minimum distance from the reflective surface (Dsr) based on the operating range: Distance from reflective surface Light curtain Type 4 Operating range Fig. 10 Formula for calculating Dsr: Dsr (m) = 0.
PSEN op4F/H-A series OPERATING MANUAL Distance between two devices of the same type The following graphic shows the distance from the interfering devices (Ddo), based on the operating range (Dop) of the pair (TX A – RX A). Reichweite Operating range Fig. 12 For the purpose of simplification, the table below states the values of the minimum safety distances required for installation, with reference to some operating ranges.

OPERATING MANUAL PSEN op4F/H-A series Fig. 13 shows an example of an installation in which interference may occur, along with two potential remedies. NO YES YES Opaque partition Fig. 13 – Interference between adjacent light curtains Should it be necessary to install two light curtains adjacently, as shown in the example in Fig. 13, the coding function is available as a possible solution (see section 7.12).
PSEN op4F/H-A series 2.2.3 OPERATING MANUAL Aligning transmitter and receiver The light curtain pair must be arranged in parallel to each other. Transmitter and receiver have connections underneath. Both units must be installed at the same time. Make sure that the light curtains are not configured as shown in Fig. 14. NO NO Fig. 14 – Light curtain alignment 2.2.
PSEN op4F/H-A series OPERATING MANUAL The table below states the operating ranges based on the number of mirrors used. Number of mirrors 1 2 3 Operating range (14 mm) 5.1 m 4.3 m 3.7 m Operating range (30 mm) 16.5 m 13.7 m 11.6 m • Never use more than three mirrors per device. • Any dust or dirt on the mirror’s reflective surface will drastically reduce the operating range. 2.2.
PSEN op4F/H-A series OPERATING MANUAL Perform the following checks: • The light curtain is in a safe state (OSSDs off) - The beams are interrupted across the whole area of the protected field using a test object (test rod) (TP-14 or TP-30) with an appropriate resolution, in accordance with the diagram in Fig. 16. • Is the light curtain aligned correctly? - Press gently on the side of the product in both directions. The red LED must not light during this process • Activate the TEST function on the TX side.
OPERATING MANUAL PSEN op4F/H-A series 3 MECHANICAL ASSEMBLY The transmitter (TX) and receiver (RX) must be assembled with their sensing surfaces facing each other. The connectors must be positioned on the same side and the distance must be within the operating limits of the relevant model (see Chapter 11). The pair of light curtains must be aligned to the best possible extent and must be as parallel as possible. The devices will be precision aligned in accordance with the description in Chapter 5.

PSEN op4F/H-A series OPERATING MANUAL 4.1 Connection guidelines The following section contains some guidelines regarding the connections, which should be followed to ensure the correct operation of the safety light curtain from the PSEN op4F/HA series. • Never place connection cable close to or in contact with cables featuring high voltage ratings and/or current fluctuations (e.g.: motor supply, inverters etc.). • Never combine the OSSD wires from several safety light curtains into one multi-pole cable.
OPERATING MANUAL PSEN op4F/H-A series Manual start Fig. 21 – Connection to safety relay – manual start The diagrams show the connection between the safety light curtains and the safety relay PNOZ s3 in automatic start mode (Fig. 20) and monitored manual start mode (Fig 21). • Avoid using varistors, RC circuits or LEDs in parallel to the relay inputs or in series connection to the OSSD outputs.
PSEN op4F/H-A series OPERATING MANUAL NOTE: The OSSDs are pulsed. The following diagram shows the time characteristic of the OSSDs. 24 V DC OSSD1 GND 24 V DC OSSD2 GND 115 µs 500 ms OSSD in safe state 1000 ms Fig.
OPERATING MANUAL PSEN op4F/H-A series 5 ALIGNMENT The transmitter and receiver must be aligned to ensure the device operates correctly. Good alignment prevents the light curtain switching incorrectly due to dust or vibration. The optimum alignment is achieved when the optical axes of the first and last beam from the transmitter coincide with the optical axes of the corresponding elements on the receiver. The light curtain has two synchronisation beams.
PSEN op4F/H-A series OPERATING MANUAL In alignment mode, the light curtain is always in a safe state and the OSSD outputs are OFF. The quality and level of the alignment is determined via the signal strength of each individual beam in alignment mode. The two synchronization beams have a higher value level. The user can see the alignment quality from the LED state at the lower end of the receiver. A. Hold the receiver in a stable position and align the transmitter until the yellow SYNC1 LED goes out.
OPERATING MANUAL PSEN op4F/H-A series 6 SETTING THE FUNCTIONS There are two options for configuring the light curtain’s functions and operating configurations: - Basis configuration mode (BCM): In basic configuration mode you have the option to use the buttons and the LED interface (transmitter/receiver) to select basic functions/parameters.
PSEN op4F/H-A series OPERATING MANUAL light curtain configuration error, which prevents non-authorised changes to the advanced configuration. Advanced configuration mode With the PSENopt Configurator (graphical user interface for PC), the user has the option to configure advanced light curtain parameters. A variety of parameters can be used to adapt the light curtain operation to your applications.

PSEN op4F/H-A series OPERATING MANUAL 7 FUNCTIONS 7.1 Restart function If the beams detect an opaque object, the OSSD output switching elements will switch (i.e. the safety contacts will open, SAFETY conditions). The restart function enables the user to define how the light curtain returns from the safe state to normal operation. There are two ways to restart the light curtain (i.e. close the OSSD safety contacts – SAFETY condition): automatic or manual restart.
OPERATING MANUAL PSEN op4F/H-A series Manual restart: When the light curtain has detected an opaque object in the protected field, the light curtain does not resume its normal operation until the object has been removed from the protected field and the reset button has been operated. The OSSD output switching elements switch back to normal operation when the RESTART signal voltage is removed again, and not after 500 ms.
PSEN op4F/H-A series OPERATING MANUAL The section below describes how the restart mode can be selected via the pushbutton as well as via the user interface. BCM configuration: Restart mode LED 5 OFF ACM Manual EDM LED 5 red (ON) OSSD PWR Auto LEVEL ACM configuration: Restart mode 7.2 Test The TEST function can be activated by operating the 24 VDC N/O pushbutton connected to the TEST input on the TX device (Pin 2 of the 5-pin M12 connector) for at least 0.5 seconds.
OPERATING MANUAL PSEN op4F/H-A series 7.3 Reset If the light curtain is blocked in a fault state, you can restore normal operation by switching the light curtain on and off or by activating the RESET function (only with critical errors). To activate the RESET function, the RESET/RESTART/ALIGN connection (Pin 3 of the 12pin connector) must be supplied with 24 V for at least 5 seconds. If the light curtain does not return to normal operating mode, the light curtain has to be switched off and on again.

A reduced operating range is recommended for cases in which several pairs of light curtains need to be assembled side by side and the coding function cannot be used. 7.
OPERATING MANUAL PSEN op4F/H-A series • It is important to note that the muting function represents a hazardous situation of the device. So it must be applied only in keeping with the necessary preventive measures. • The muting sensors must be correctly positioned to avoid unintended muting becoming potentially dangerous for the operator. • MUTING1 and MUTING2 cannot be activated simultaneously.
PSEN op4F/H-A series 7.7.3 OPERATING MANUAL Typical muting application and sensor connection Safety sensor A22 A21 A12 A11 Fig. 41 – Typical muting application The diagram above shows a typical muting application: the protection device installed on the conveyor must allow the package to pass through but not the operator. The light curtain temporarily suspends its safety function when the sensors A11, A21, A12, A22 are activated in the correct sequence.
OPERATING MANUAL PSEN op4F/H-A series Fig. 42 – T muting timings The sensors labelled A1/A2 are connected to the muting input (MUTING1) and the sensors labelled B1/B2 are connected to the MUTING2 input. Sensors ending in “1” are on the same side of the light curtain and therefore on the opposite side to the sensors ending in “2”.
PSEN op4F/H-A series OPERATING MANUAL L-Muting With L-muting, the light curtain is muted if the input signals switch to 24 VDC in accordance with a certain sequence: MUTING1 must be activated first; only then can MUTING2 be activated. If MUTING2 should activate before MUTING1, the device will not switch to muting mode; “T12” represents the activation delay between MUTING1 and MUTING2, which users can select via ACM.

PSEN op4F/H-A series 7.7.5 OPERATING MANUAL Muting timeout The muting timeout describes the time for the maximum duration of the muting function; once the timeout has elapsed, muting is ended. Users have the option to set this time in BCM as well as ACM mode. In BCM mode they can select the timeout to be 10 minutes long or infinite; “infinite” means that the muting timeout may potentially never end: as long as the muting conditions are present, the muting function will be maintained.
OPERATING MANUAL PSEN op4F/H-A series . 7.7.6 Muting filter This function prevents muting from being activated unintentionally. The muting filter is a filter arranged on the muting inputs: Transitions of the muting signal from high to low are only considered valid if they are maintained for a period (Tf) of over 100 ms. If this function is disabled, the logic level of the muting sensors will correspond to the signal level on the wire. ACM configuration: Muting filter Fig.
PSEN op4F/H-A series 7.7.7 OPERATING MANUAL Partial muting The muting type can be configured: total or partial muting. Partial muting can prove useful when the user wishes to limit the effects of the muting function exclusively to the selected zones. With ACM configuration, the user can select a maximum of 5 muting zones, each of which is defined in accordance with the following parameters: - Position: First beam of muting zone (starting from the user display cover).
OPERATING MANUAL PSEN op4F/H-A series 7.8 Override The override function allows the user to disable the safety functions if the machine needs to be restarted, even though one or more of the light curtain beams have detected an object in the protected field. For example, a typical application would be to examine recurring blockages more precisely and to rectify the cause. These may be work materials between the light curtain’s transmitter and receiver, which trigger the light curtain.
PSEN op4F/H-A series 7.8.1 OPERATING MANUAL Override mode It is possible to activate the override inputs: Level or edge. As shown in the diagram below, the two types of activation sequence for the override are recorded in the external inputs: • Activated by level: The override remains activated until both contacts are closed and at least one muting sensor has been interrupted.
OPERATING MANUAL PSEN op4F/H-A series BCM configuration: Override mode LED 8 OFF ACM Edge EDM LED 8 ON green OSSD PWR Level LEVEL ACM configuration: Override mode 7.8.2 Override timeout BCM mode The timeout of the override status is 120 seconds in both operating modes. If the override conditions remain active and both contacts remain closed for more than 120 seconds (this condition only applies when the mode is activated by level), the override will go low after a maximum of 120 seconds.
PSEN op4F/H-A series OPERATING MANUAL ACM configuration: Override timeout 7.8.3 Override restart This can only be selected when the light curtain is in manual restart mode; users can select the type of override restart: normal or automatic. The RESET/RESTART/ALIGN input (Pin 3 of the 12-pin M12 connector – RX-side) must be connected to a 24 V DC N/O contact. Fig.
OPERATING MANUAL PSEN op4F/H-A series Automatic override restart The OSSD output switching elements resume normal operation when the RESTART signal goes low and not after 500 ms. With a timeout of 5 s on RESTART with 24 V an error is generated, which blocks the light curtain. The output signals switch to 24 VDC after a time period that represents the maximum value between the reset time and the high restart time (greater than or equal to 500 ms). This time period may lie between 500 ms and 5 s.
PSEN op4F/H-A series OPERATING MANUAL Normal override restart The OSSD outputs switch to normal operation when the RESTART signal goes low and not after 500 ms. With a timeout of over 5 s an error is generated, which blocks the light curtain. The output signals switch to 24 V DC after a time period that represents the maximum value between the reset time and switched restart (greater than or equal to 500 ms).This time period may lie between 500 ms and 5 s.
OPERATING MANUAL PSEN op4F/H-A series 7.9 Blanking Blanking is a function of the safety light curtains, which enables an opaque object to be inserted into the protected field without stopping the machine’s normal operation. Blanking can only be used when certain safety conditions are present and in accordance with a configurable operating logic. The blanking function is particularly useful when the light curtain's protected field will inevitably be within moving parts or material of the machine.
PSEN op4F/H-A series 7.9.1 OPERATING MANUAL Fixed blanking Fixed blanking enables a certain part of the protected area (e.g. a certain number of beams) to be hidden, while all other beams operate normally. The blanking zone can be achieved using the teach-in process: the user must hold down the 24 V DC N/O teach-in contact (Pin 4 of the 12-pin M12 connector - RX) for at least 3 seconds, while an object interrupts the zone designed for blanking.
OPERATING MANUAL 7.9.2 PSEN op4F/H-A series Fixed blanking with increased tolerance This is fixed blanking with a tolerance on only one side of the blanking zone, so the user must select “top” or “bottom” tolerance. This function is particularly helpful with conveyor belts (which use fixed blanking) with goods transported along them (dimensions within the tolerance). Only fixed blanking zones can be set on the tolerance side.
PSEN op4F/H-A series 7.9.5 OPERATING MANUAL Reduced resolution Reduced resolution represents a particular type of floating blanking, in which multiple objects can each interrupt a certain number of beams, while the light curtain remains in normal operating mode. The number below indicates how many adjacent beams the object can interrupt to guarantee that the light curtain remains in normal operating mode.
OPERATING MANUAL PSEN op4F/H-A series The existence of the tolerance is indicated by LEDs flashing on the user interface, as shown below. Tolerance display ACM EDM OSSD PWR Tolerance active LEVEL LED 3 flashes yellow The tolerance affects the light curtain's actual resolution. Make sure that the new resolution is considered when calculating a new mechanical assembly.
PSEN op4F/H-A series 7.9.7 OPERATING MANUAL Blanking mode in the basic configuration Only a reduced series of configurations can be implemented in basic configuration mode. BCM configuration: Fixed blanking LED 8 OFF ACM 2 fixed blanking zones EDM LED 8 ON green OSSD PWR 1 fixed blanking zone LEVEL • 1 fixed blanking zone: only 1 zone can be configured as a blanking zone. • 2 fixed blanking zones: 2 zones can be configured as blanking zones.
OPERATING MANUAL 7.9.8 PSEN op4F/H-A series Blanking mode in advanced configuration A maximum of 5 blanking zones (fixed + floating) can be configured in ACM (however, at least one separating beam is required between the zones). The user can select the number of beams via ACM. • Reduced resolution ACM configuration The software calculates the maximum object size (in mm) that the light curtain can detect without triggering a SAFE STATE.
PSEN op4F/H-A series OPERATING MANUAL • FIXED blanking The panel on the right shows the settings for the active blanking zone (in the example shown below, the active blanking zone is 3 beams in size and is 7 beams from the bottom of the light curtain; no tolerance is set).
OPERATING MANUAL PSEN op4F/H-A series • FLOATING blanking with total surveillance Floating objects can move up and down, interrupting several beams in the process. These objects can overlap or change positions. The object must be within the protected field at all times and interrupt the number of configured beams with a fixed tolerance of one beam. This is necessary so that a moving object always interrupts a different number of beams.
PSEN op4F/H-A series OPERATING MANUAL 7.10 Cascading An internal communication bus can be used to cascade several pairs of light curtains with each other. The normal connections at the top and bottom of the light curtain are used with the aid of a cascading cable. The OSSDs are only physically connected to the Master unit. If transmission should fail due to a stuck-at fault or signal degradation, both the Master and Slave units switch to a safe state.
OPERATING MANUAL PSEN op4F/H-A series Fig. 57 – PNP timings NPN configuration With this configuration, the load is connected between 24 V DC and the OSSD output switching element. In normal operation, the output voltage of the OSSD is 0 V DC. If an opaque object interrupts the beams, the OSSD status switches from 0 VDC to 24 V. Fig.
PSEN op4F/H-A series OPERATING MANUAL Fig. 59 – NPN timings 7.12 Coding The coding function enables the light curtain to operate normally even if an interference condition occurs with another light curtain. This is particularly true if the transmitter TX of the first light curtain emits beams in the direction of the receiver RX of the second light curtain. To counter this, both light curtains must be configured with different codes (see under Chapter 2.2.2).
OPERATING MANUAL PSEN op4F/H-A series • Code 1 or Code 2 If the two light curtains − are installed at a distance that is lower than the minimum distance permitted for identical devices − and has RX on the same side, the user must configure the light curtains with different codes. NOTE: The configuration performed using the GUI only changes the code on the RX side; for the light curtain to operate correctly, the user must configure the TX side with the same code via BCM. Fig.
PSEN op4F/H-A series OPERATING MANUAL This function can be set in the RX unit as well as the TX unit via BCM. Two codes are available.
OPERATING MANUAL PSEN op4F/H-A series 8 DIAGNOSTICS 8.1 Status of LEDs ACM Meaning of LED EDM OSSDs Power On the bottom left-hand side of the light curtain 8 LEDs help users to monitor and check the state of the light curtain in alignment mode, in normal mode and when troubleshooting.
