As shown in the wiring diagrams, the models ES-FA-9AA and ES-FA-11AA E-Stop Safety Modules are designed to monitor a 1-channel or Features and Terminals - 2-channel E-stop switch. A 2-channel E-stop switch has two electrically isolated contacts. ES-FA-9AA ES-FA-11AA EK) SOS - WARNING: • Ensure the safety circuit integrity © 000—EO 000 • The safety circuit integrity level is affected by the design and installation of the safety devices and the Power ON LED [ Power J Se [ Power J— - means of interfacing with those devices. Channel 1 - • Perform a risk assessment to determine the Active LED Channel 2 - appropriate safety circuit integrity level or category to Active LED ensure the expected risk reduction is achieved and all applicable regulations and standards are in compliance (see ANSI B11.0 and ANSI B11.19, ISO 0000202 eoee202 12100 and ISO13849-1 or the applicable standards). ## Safety Circuit Integrity and EN ISO 13849-1 Safety Circuit Principles Safety circuits involve the safety-related functions of a machine that minimize the level of risk of harm. These safety-related functions can prevent initiation, or they can stop or remove a hazard. The failure of a safety-related function or its associated safety circuit usually results in an increased risk of harm. The integrity of a safety circuit depends on several factors, including fault tolerance, risk reduction, reliable and well-tried components, well-tried safety principles, and other design considerations. Depending on the level of risk associated with the machine or its operation, an appropriate level of safety circuit integrity (performance) must be incorporated into its design. Standards that detail safety performance levels include ANSI B11.19 Performance Criteria for Safeguarding and EN ISO 13849-1 Safety-Related Parts of a Control System. ## Safety Circuit Integrity Levels Safety circuits in International and European standards have been segmented into categories, depending on their ability to maintain their integrity in the event of a failure. The most recognized standard that details safety circuit integrity levels is EN ISO 13849-1, which establishes five levels: Categories B, 1, 2, 3, and the most stringent, Category 4. In the United States, the typical level of safety circuit integrity has been called control reliability. Control reliability typically incorporates redundant control and self-checking circuitry and has been loosely equated to EN ISO 13849-1 Categories 3 and 4 (see CSA Z432 and ANSI B11.TR4). If the requirements described by EN ISO 13849-1 are to be implemented, a risk assessment must first be performed to determine the appropriate category, in order to ensure that the expected risk reduction is achieved. This risk assessment must also take into account national regulations, such as U.S. control reliability or European “C” level standards, to ensure that the minimum level of performance that has been mandated is complied with. © Banner Engineering Corp. All rights reserved. www.bannerengineering.com page 7 of 21 05-Nov-25 Overview ES-FA-9AA and -11AA E-Stop Safety Module Product Manual ## Fault Exclusion An important concept within the category requirements of EN ISO 13849-1 is the probability of the occurrence of the failure, which can be decreased using the "fault exclusion" method. This method assumes that the possibility of certain well-defined failure(s) can be reduced to a point where the resulting fault(s) can be disregarded. Fault exclusion is a tool a designer can use during the development of the safety-related part of the control system and the risk assessment process. It allows the designer to eliminate the possibility of various failures and justify it through the risk assessment process to meet the requirements of Categories 2, 3, or 4. See EN ISO 13849-1/-2 for further information. ## Monitoring of Safety Devices Requirements vary widely for the level of control reliability or safety category per ISO 13849-1 in safety applications. While Banner Engineering always recommends the highest level of safety in any application, it is the responsibility of the user to safely install, operate and maintain each safety system and comply with all relevant laws and regulations. Although only two applications are listed, the Module can monitor a variety of devices as long as the input requirements are complied with (see Electrical Installation and Specifications). The Safety Module does not have 500 ms simultaneity between inputs and thus cannot be used for monitoring a two-hand control. In all cases, the safety performance (integrity) must reduce the risk from identified hazards as determined by the machine's risk assessment. ## WARNING: - Do not mute or bypass any emergency stop device - Muting or bypassing the safety outputs renders the emergency stop function ineffective. - ANSI B11.19, NFPA 79 and IEC/EN 60204-1 require that the emergency stop function remains active at all times. ## Emergency Stop Push Buttons and Rope/Cable Pull Switches The safety inputs can be interfaced with positive-opening switches to monitor an emergency-stop (E-stop) push button or rope/cable pull. The switch must provide one or two contacts for safety which are closed when the switch is armed. Once activated, the E-stop switch must open all its safety-rated contacts, and must require a deliberate action (such as twisting, pulling, or unlocking) to return to the closed-contact, armed position. The switch must be a "positive-opening" (or directopening) type, as described by IEC 60947-5-1. Standards NFPA 79, ANSI B11.19, IEC/EN 60204-1, and ISO 13850 specify additional emergency stop switch device requirements, including the following: - Emergency-stop push buttons shall be located at each operator control station and at other operating stations where emergency shutdown is required. - Stop and emergency-stop push buttons shall be continuously operable and readily accessible from all control and operating stations where located. Do not mute or bypass E-stop buttons or rope/cable pulls. - Actuators of emergency-stop devices shall be colored red. The background immediately around the device actuator shall be colored yellow (where possible). The actuator of a push-button-operated device shall be of the palm or mushroom-head type. - The emergency-stop actuator shall be a self-latching type. In addition, for Rope/Cable Pull Installations Only: - The wire rope should be easily visible and readily accessible along its entire length. Red markers or flags may be fixed on the rope to increase its visibility. - The rope or cable pull must provide constant tension and must have the capability to react to a force in any direction. - Mounting points, including support points, must be rigid. - The rope should be free of friction at all supports. Pulleys are recommended. - • The switch must have a self-latching function that requires a manual reset after actuation Some applications may have additional requirements; comply with all relevant regulations. See the device manufacturer's installation instructions for complete information. page 8 of 21 © Banner Engineering Corp. All rights reserved. www.bannerengineering.com 05-Nov-25 Overview ES-FA-9AA and -11AA E-Stop Safety Module Product Manual WARNING: - Do not mute or bypass any emergency stop device - Muting or bypassing the safety outputs renders the emergency stop function ineffective. - ANSI B11.19, NFPA 79 and IEC/EN 60204-1 require that the emergency stop function remains active at all times. ## Interlocked Guards (Gates) The safety inputs can be interfaced with positive-opening safety switches to monitor the position of an interlock guard or gate. Each switch must provide electrically isolated contacts: at minimum, one normally closed (N.C.) contact from each individually mounted switch. The contacts must be of "positive-opening" (direct-opening) design, as described by IEC609475-1, with one or more normally closed contacts rated for safety. In addition, the switches must be mounted in a "positive mode," to move/disengage the actuator from its home position and open the normally closed contact when the guard opens. The design and installation of the interlocked guard and the safety switches should comply with ANSI B11.19, ISO14119, ISO 14120, and/or other applicable standards. See the device manufacturer installation instructions for complete information. In higher levels of safety performance, the design of a dual-channel coded magnetic switch typically uses complementary switching, in which one channel is open and one channel is closed at all times. The inputs of the Safety Module do not support complementary switching , and thus should not be used with coded magnetic safety switches. © Banner Engineering Corp.

It is not designed for exposed wiring. It is the user’s responsibility to house the ES-FA-9AA/11AA in an enclosure with NEMA 3 (IEC IP54) rating, or better. The ES-FA-9AA/11AA mounts directly to standard 35 mm DIN rail. Heat Dissipation Considerations: For reliable operation, ensure that the operating specifications are not exceeded. The enclosure must provide adequate heat dissipation so that the air closely surrounding the ES-FA-9AA/11AA does not exceed the maximum operating temperature stated in the Specifications. Methods to reduce heat build-up include venting, forced airflow (for example, exhaust fans), adequate enclosure exterior surface area, and spacing between modules and other heat sources. © Banner Engineering Corp.

Serious injury or death could result. - Always disconnect power from the safety system (for example, device, module, interfacing, etc.), guarded machine, and/or the machine being controlled before making any connections or replacing any component. Lockout/tagout procedures might be required. Refer to OSHA 29CFR1910.147, ANSI Z244-1, or the applicable standard for controlling hazardous energy. - Make no more connections to the device or system than are described in this manual. Electrical installation and wiring must be made by a Qualified Person[(1)] and must comply with the applicable electrical standards and wiring codes, such as the NEC (National Electrical Code), NFPA 79, or IEC 60204-1, and all applicable local standards and codes. It is not possible to give exact wiring instructions for a Safety Module that interfaces to a multitude of machine control configurations. The following guidelines are general in nature. The Safety Module has no delay function. Its output relay contacts open within 25 milliseconds after a safety input opens. This classifies the Safety Module as a functional stop "Category 0" control, as defined by NFPA 79 and IEC/EN 60204-1. The safety inputs can be connected to: - A +24 V DC source that is switched by a hard/relay contact in single-channel connection configuration, or - Hard/relay contacts in a dual-channel hookup configuration using terminals S11-S12 and S21-S22. ## Safety Input Device Wiring Options The operation of all dual-channel wiring options is concurrent, meaning that input channel 1 and input channel 2 must be in the same state in both the STOP and RUN condition, but with no simultaneity (timing) requirement between the channels. The dual-channel wiring configuration is able to detect certain failures and faults, such as short circuits, that could result in a loss of the safety function. Once such a failure or fault is detected, the Safety Module will turn OFF (open) its safety outputs until the problem is fixed. This circuit can meet ISO 13849-1 Category 2, 3, or 4 requirements, depending on the safety rating and the installation of the safety input device. This circuit can detect a short circuit between channels or to another source of power, at a minimum, when the device is actuated. A single device with redundant outputs that can fail in such a manner to lose the safety function, such as a single safety interlocking switch, can typically meet only a Category 2. See below for means to eliminate or minimize the possibility of failures and faults that could result in the loss of the safety function(s). The single-channel wiring configuration cannot detect short circuits to secondary sources of +24 V DC or detect the loss of the switching function of the safety input device (that is, it is not redundant) and thus this circuit typically can meet only ISO 13849-1 Category 2. > (1) A person who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowledge, training and experience, has successfully demonstrated the ability to solve problems relating to the subject matter and work. © Banner Engineering Corp. All rights reserved. www.bannerengineering.com page 11 of 21 05-Nov-25 ES-FA-9AA and -11AA E-Stop Safety Module Product Manual Electrical Installation It is recommended that in all circumstances the installation of the Safety Module and its associated safety input devices are installed to eliminate or minimize the possibility of failures and faults that could result in the loss of the safety function(s). Methods to eliminate or minimize the possibility of these failures include, but are not limited to: - Physically separating interconnecting control wires from each other and from secondary sources of power. - Routing interconnecting control wires in separate conduit, runs, or channels. - Locating all elements (modules, switches, and devices under control) within one control panel, adjacent to each other, and directly connected with short wires. - Properly installing multi-conductor cabling and multiple wires through strain-relief fittings. (Over-tightening of a strainrelief can cause short circuits at that point.) - Using positive-opening components as described by IEC 60947-5-1 that are installed and mounted in a positive mode. - Periodically checking the functional integrity/safety function and training operators, maintenance personnel, and others associated with the operation of the machine to recognize and immediately correct such failures. If you have any questions about your intended use, please contact a Banner applications engineer. ## Connection of Multiple Switches Connect the poles of multiple switches, such as e-stop switches, as shown in the figure at right. The switches are shown in the "armed" position with both contacts closed. Multiple switches connected to one Safety Module must be series connected (see figure at right and the warning, Multiple Switching Devices). **==> picture [205 x 151] intentionally omitted <==** **----- Start of picture text -----**<br> Series connection of multiple e-stop switches<br>E-Stop E-Stop<br>S11 S21 S22 S12<br>**----- End of picture text -----**<br> ## WARNING: - Connect two or more devices to the same safety module (controller) in series - Connecting devices in parallel defeats the switch contact monitoring ability of the module and creates an unsafe condition that could result in serious injury or death. - Failure to test each device individually in this manner could result in undetected faults and create an unsafe condition that could result in serious injury or death. - Connect the contacts of the corresponding pole of each switch in series. Never connect the contacts of multiple switches in parallel. Individually actuate (engage) each device, then release (or re-arm) and reset the safety module. This allows the module to check each switch and its wiring to detect faults. Perform this check during the prescribed checkouts. page 12 of 21 © Banner Engineering Corp.

To achieve Category 4 operation per ISO 13849-1, two positive-opening safety switches must operate concurrently when the guard or gate is opened. The Safety Module verifies concurrent opening of two contacts – one from each safety switch. Reset of the Safety Module is not possible if one switch fails to open or if a short circuit between the safety interlocking switches occurs. A switch with a PNP (sourcing) output can be used to reset the module. The PNP output would supply 24 V DC to S34. ## Connection of Reset Switch The reset circuit switch can be any mechanical switch, such as a normally open momentary switch, or a two-position key switch. The reset switch must be capable of reliably switching 8 V DC to 12 V DC at 10 milliamps to 15 milliamps. As shown in the wiring diagrams, the reset switch connects between Safety Module terminals S33 and S11. The reset switch must be located outside of – and not be accessible from – the area of dangerous motion, and must be positioned so that any area of dangerous motion may be observed by the switch operator during the reset procedure. See warning below. ## WARNING: - Install reset switches properly - Failure to properly install reset switches could result in serious injury or death. - Install reset switches so that they are accessible only from outside, and in full view of, the safeguarded space. Reset switches cannot be accessible from within the safeguarded space. Protect reset switches against unauthorized or inadvertent operation (for example, through the use of rings or guards). If there are any hazardous areas that are not visible from the reset switches, provide additional safeguarding. © Banner Engineering Corp. All rights reserved. www.bannerengineering.com page 13 of 21 05-Nov-25 ES-FA-9AA and -11AA E-Stop Safety Module Product Manual Electrical Installation ## Automatic Reset Mode The Safety Module may be configured (via connection) for automatic reset. If no MSC contacts are monitored, install a jumper between terminals S33 and S34. The Safety Module will reset (and its outputs energize) as soon as the switch returns to its armed (closed-contact) position. Automatic reset is useful for some automated processes. However, if automatic reset is used, it is necessary to provide a means of preventing resumption of hazardous machine motion, until an alternate reset procedure is performed. The alternate procedure must include a reset/restart switch, located outside the area of dangerous motion, which is positioned so that any area of dangerous motion may be observed by the switch operator during the reset procedure. ## WARNING: - Reset routine required - Failure to prevent the machine from restarting without actuating the normal start command/device can create an unsafe condition that could result in serious injury or death. - Do not allow the machine to restart without actuating the normal start command/device. Perform the reset routine after clearing the cause of a stop condition, as required by U.S. and international standards. NOTE: The minimum time required for the Module to be in a STOP or OFF condition is 250 ms. This “recovery time” (OFF-state) is required for the internal circuitry of the Safety Module to normalize, allowing a reliable reset to occur. A lockout occurs if the Module is cycled too quickly. To clear the lockout, the Module must be recycled, meeting the minimum OFF time requirements. ## ES-FA-9AA and -11AA Wiring **==> picture [123 x 8] intentionally omitted <==** **----- Start of picture text -----**<br> Dual-Channel E-Stop Applications<br>**----- End of picture text -----**<br> **==> picture [338 x 186] intentionally omitted <==** **----- Start of picture text -----**<br> Auto Reset Manual Reset<br>+V DC common +V DC common<br>24 V AC/DC 24 V AC/DC<br>A1 A2 A1 A2<br>E-Stop Reset<br>Switch<br>MSC1 MSC3 MSC1 MSC2 MSC3<br>S11 S33 MSC S33<br>Monitor<br>ES-FA-9AA Contacts ES-FA-9AA<br>S21 or S11<br>S34 Jumper S34 (No Connection)<br>MSC2<br>S22 S21<br>See WARNING E-Stop<br>Below Switch<br>S12 S22<br>S12<br>**----- End of picture text -----**<br> page 14 of 21 © Banner Engineering Corp.

An MSC is defined as an electrically powered device, external to the Safety Module, which stops the machinery being controlled by immediately removing electrical power to the machine and (when necessary) by applying braking to dangerous motion. This stopping action is accomplished by removing power to the actuator of either MSC. ## External Device Monitoring To satisfy the requirements of Control Reliability (OSHA and ANSI), Category 3 and 4 of ISO 13849-1, the master stop control elements (MSCs) must each offer a normally closed, forced-guided (mechanically linked) monitor contact. Connect one normally closed monitor contact from each master stop control element as shown in the single-channel wiring diagrams. In operation, if one of the switching contacts of either MSC fails in the energized condition, the associated monitor contact will remain open. Therefore, it will not be possible to reset the Safety Module. If no MSC-monitor contacts are monitored, a jumper must be installed as shown in the wiring diagrams. It is the user's responsibility to ensure that any single failure will not result in a hazardous condition and will prevent a successive machine cycle. ## Overvoltage Category II and III Installations (EN 50178 and IEC 60664-1) The ES-FA-9AA/11AA is rated for Overvoltage Category III when voltages of 1 V to 150 V AC/DC are applied to the output relay contacts. It is rated for Overvoltage Category II when voltages of 151 V to 250 V AC/DC are applied to the output relay contacts and no additional precautions are taken to attenuate possible overvoltage situations in the supply voltage. The ESFA-9AA/11AA can be used in an Overvoltage Category III environment (with voltages of 151 V to 250 V AC/DC) if care is taken either to reduce the level of electrical disturbances seen by the ES-FA-9AA/11AA to Overvoltage Category II levels by installing surge suppressor devices (for example, arc suppressors), or to install extra external insulation in order to isolate both the ES-FA-9AA/11AA and the user from the higher voltage levels of a Category III environment. For Overvoltage Category III installations with applied voltages from 151 V to 250 V AC/DC applied to the output contact(s): the ES-FA-9AA/11AA may be used under the conditions of a higher overvoltage category where appropriate overvoltage reduction is provided. Appropriate methods include: - An overvoltage protective device - A transformer with isolated windings - A distribution system with multiple branch circuits (capable of diverting energy of surges) - A capacitance capable of absorbing energy of surges - A resistance or similar damping device capable of dissipating the energy of surges © Banner Engineering Corp. All rights reserved. www.bannerengineering.com page 15 of 21 05-Nov-25 ES-FA-9AA and -11AA E-Stop Safety Module Product Manual Electrical Installation When switching inductive AC loads, it is good practice to protect the ES-FA-9AA/11AA outputs by installing appropriatelysized arc suppressors. However, if arc suppressors are used, they must be installed across the load being switched (for example, across the coils of external safety relays), and never across the ES-FA-9AA/11AA’s output contacts. ## Auxiliary Monitor Contact (Model ES-FA-11AA Only) The action of the auxiliary monitor contact, terminals 31-32, inversely "follows" the action of the safety outputs. The 31-32 auxiliary monitor contact is to be used only for control functions that are NOT safety-related. A typical use is to communicate the status of the Safety Module output to a programmable logic controller (PLC). ## WARNING: - Interfacing master stop controls - Failure to follow these instructions could result in serious injury or death. - Unless the same degree of safety is maintained, never wire an intermediate device(s) (PLC, PES, PC) between the safety module outputs and the master stop control element it switches such that a failure causes a loss of the safety stop command or the failure allows the safety function to be suspended, overridden, or defeated. - When forced-guided, mechanically linked relays are added as intermediate switching devices, a normally closed (N.C.) forced-guided monitor contact from each relay must be added to the series feedback loop or properly wired external device monitoring channel. ## WARNING: - Properly install arc or transient suppressors - Failure to follow these instructions could result in serious injury or death. - Install any suppressors as shown across the coils of the machine primary control elements. Do not install suppressors directly across the output contacts of the safety or interface module. In such a configuration, it is possible for suppressors to fail as a short circuit. **==> picture [429 x 204] intentionally omitted <==** **----- Start of picture text -----**<br> Machine Control Circuit Connections<br>ES-FA-9AA ES-FA-11AA<br>Machine<br>Machine<br>Master Stop<br>Master Stop<br>Control Elements<br>L1 K1A6A max.K2A L2 L1 K1A7A max.K2A Control Elements L2<br>13 14 MSC1 13 14 MSC1<br>6A max. 7A max.<br>MachineControl 23 K1B K2B 24 MSC2 MachineControl 23 K1B K2B 24 MSC2<br>Circuits<br>Circuits<br>6A max.<br>K1C K2C 7A max. *Arc suppressors<br>33 34 MSC3 31 K1C 32 (see WARNING)<br>1H La) | ied<br>K2C<br>Feedback<br>(optional)<br>*Arc suppressors<br>fest (see WARNING) | d fe<br>* *<br>* *<br>*<br>**----- End of picture text -----**<br> page 16 of 21 © Banner Engineering Corp.

Exercise extreme caution whenever machine control power is or might be present. Always disconnect power to the machine control elements before opening the enclosure housing of the module. 1. Remove power from the machine control elements. 2. Ensure the safety device is in a STOP or "open-contact" state (for example, actuate the E-stop switch to open its contacts). 3. Apply power to the Safety Module at terminals A1 and A2 (see wiring diagrams). Verify that only the Input Power indicator (see "Overview" on page 7) is ON. If either input channel 1 (K1) or input channel 2 (K2) indicators are ON at this point, disconnect the input power and check all wiring. Return to step 2 after the cause of the problem has been corrected. 4. Reset or otherwise cause the safety device to reach an ON or "closed-contact" state (for example, arm the E-stop switch to close its contacts). Automatic reset: Ch1 (K1) and Ch2 (K2) indicators should come ON, and the safety output contacts should close. Manual reset: From an open condition, close the reset switch for approximately ¼ second, and then re-open. The Ch1 (K1) and Ch2 (K2) indicators should both come ON steady at this time. If either indicator comes ON before the reset switch is opened, disconnect the input power and check all wiring. Return to step 2 after correcting the problem. 5. Cause the safety device to generate a STOP or "open-contact" state (for example, actuate the E-stop switch to open its contacts). The Ch1 (K1) and Ch2 (K2) indicators should turn OFF simultaneously. If either indicator remains ON, disconnect the input power and check all wiring. Return to step 2 after the cause of the problem has been corrected. 6. If more than one safety device is series-connected to the Safety Module, run the above checkout procedure individually for EACH device. 7. Close and secure the enclosure in which the Safety Module is mounted. Apply power to the machine control elements and perform the Periodic Checkout Procedure. ## WARNING: - Connect two or more devices to the same safety module (controller) in series - Connecting devices in parallel defeats the switch contact monitoring ability of the module and creates an unsafe condition that could result in serious injury or death. - Failure to test each device individually in this manner could result in undetected faults and create an unsafe condition that could result in serious injury or death. - Connect the contacts of the corresponding pole of each switch in series. Never connect the contacts of multiple switches in parallel. Individually actuate (engage) each device, then release (or re-arm) and reset the safety module. This allows the module to check each switch and its wiring to detect faults. Perform this check during the prescribed checkouts. © Banner Engineering Corp. All rights reserved. www.bannerengineering.com page 17 of 21 05-Nov-25 ES-FA-9AA And -11AA E-Stop Safety Module Product Manual ## Chapter Contents ## Chapter 6 ## Periodic Checkout Procedure The functioning of the Safety Module and the device(s) connected to it must be verified on a regular periodic basis to ensure proper operation (see also the machine manufacturer’s recommendations). 1. With the machine running, cause the safety device to generate a STOP or "open-contact" state (e.g., actuate the E- stop switch to open its contacts). Verify that the machine stops. 2. Reset or otherwise cause the safety device to reach an ON or "closed-contact" state. Verify that the machine does not restart. 3. If using manual reset mode, close and then open the reset switch within 3 seconds. Verify that the machine can be restarted by normal initiation. 4. If more than one safety device is series-connected to the Safety Module, run the above checkout procedure individually for EACH device. © Banner Engineering Corp.
