2-1 2 Cable Selection and Function Functions Functions and Features There are two types of cables that can be used with the SL-V. One is simple function type and another is multi-function type. The type of cable used determines the functions that can be used. (The number of wires is different from each other.) Additionally, there are functions that can be activated with or without the SL-V Configurator (SL-VH1S). Refer to the following chart.
2-1 Cable Selection and Function Cable color and pin assignment 2 Transmitter Pin No. Wire color Assigned function Functions and Features Simple function type Receiver Pin No.
2-2 Self-diagnosis Function Lockout condition 2 Functions and Features The SL-V performs self-diagnosis for approx. 4.5 seconds after the power is turned on and checks for errors in the SL-V. Self-diagnosis is also performed periodically during normal operations. If the self-diagnosis function detects an error, the SL-V goes to Lockout condition and the OSSD is kept in OFF state even if no interruption exists in the detection zone. The indicators operate in the following manner during lockout condition.
2-2 Self-diagnosis Function OSSD 2 The internal control circuit receives a feed-back signal (OFF signal) based on the self-diagnosis, the SLV determines that its output circuit is operating normally. If this OFF signal is not returned to the internal control circuit, the SL-V determines that there is a problem in its output circuit or wiring and goes to the lockout condition. ON Functions and Features The OSSD is a safety-related control output.
2-3 Series Connection Up to three SL-V units can be serially connected and used as a single light curtain. Use the series connection cables that KEYENCE provides as an optional part. ( See "Series connection cable" (page 1-6)) 2 Example of use with 3 units in series connection Receiver Transmitter Functions and Features Sub unit 2 Series connection cable (10 m max.) Receiver Transmitter Sub unit 1 Series connection cable (10 m max.
2-4 Interlock Function Interlock is a function to prevent that the OSSD automatically goes to the ON-state from the OFF-state. You can prevent the unintended start-up and/or the unintended restart of the machine if the interlock is applied to the SL-V. You can determine whether the interlock function is enabled at start-up, at restart or both through the SL-V Configurator (SL-VH1S). In this sentence, start-up and restart means as follows.
2-4 Interlock Function This mode can be used for the machine that nobody can go into or approach the hazardous area with only passing through the protection zone, or can be used if the safety-related part of a control system other than the SL-V, such as safety relay unit, can ensure the safety with other means. 2 Functions and Features Manual reset mode: Interlock function works. The SL-V starts operation if the SL-V receives the reset operation.
2-4 Interlock Function Releasing lockout condition with a switch Use the reset input (yellow wire on the receiver) for releasing lockout condition.
2-4 Interlock Function 2 Other than Automatic start / Automatic reset mode This section explains the settings other than the combination of automatic start and automatic reset mode. Functions and Features Configuration Wiring method (Pink wire on the transmitter) SL-V can be set as the combination of manual start and manual reset mode through the wiring in the following manner. If this function is set through the SL-VH1S, it cannot be set through the wiring.
2-4 Interlock Function Interlock-reset-ready output The Interlock-reset-ready output is a NON-SAFETY-RELATED function. The Interlock-reset-ready output (Green wire on the transmitter) is enable when manual start or manual restart is set. This output informs the external devices (non-safety-related devices) that the interlock state on the SL-V is ready to be released by pressing the reset button because the SL-V does not detect any interruptions in the detection zone.
2-4 Interlock Function 2 Time chart Time chart in case of interruption in the detection zone. Functions and Features No SL-V interruption Interruption (1) Interlock-reset-ready output (2) ON OFF ON OFF 100 ms max. Reset input ON OFF 100 ms min. OSSD Interlock ON OFF 150 ms max.

2-5 2 AUX (Auxiliary) Output Functions and Features The AUX (Auxiliary) output is a NON-SAFETY-RELATED function. This output just informs an external device (non safety-related device) of the operations of the SL-V and operates in synchronization with OSSD operation. It can only be connected to a PLC or similar non-safety devices. Danger The AUX output is not allowed to be used as a safety output for safety-related control systems.
2-6 External Device Monitoring (EDM Function) EDM (External Device Monitoring) is a function of the SL-V that monitors the state of control devices which are externally connected to the SL-V. The SL-V can detect a fault such as welded contacts on external devices if the EDM function is activated.
2-7 2 Wait Input Function The wait input is a NON-SAFETY-RELATED function. This is the function that puts the OSSD into an OFF state through a signal from an external device (non safety-related device). Functions and Features How to use (1) The signal from the external non safety-related control device is connected to the wait input. When this signal is ON, the OSSD of the SL-V goes to OFF.

2-8 2 State Information Output Functions and Features The state information output is a NON-SAFETY-RELATED function. The state information output is a function that informs the external devices (non safety-related devices) of the current state of the SL-V. It does this using state information outputs 1 and 2.
2-8 State Information Output Normal mode (default) 2 Summary Functions and Features When the power turns on, the pulse output (number of pulses on state information output 2 while state information output 1 is ON) indicates that the SL-V is in normal operation. After that, if the SL-V changes to one of the states shown below ("SLV state" column), the pulse output generates the corresponding number of pulses one time to indicate the state of the SL-V.
2-8 State Information Output Time chart 2 The AUX (Auxiliary) output operates in synchronization with OSSD operation.
2-8 State Information Output Example when going into a lockout condition from a muted condition • When using a PNP output type cable to connect to a PNP input device • When using an NPN output type cable to connect to an NPN input device ON OFF AUX SL-V goes to lockout condition Functions and Features OSSD 2 Muted condition ON OFF 50 ms max. 120 ms min. State information output 1 ON OFF 40 ms min.

2-8 State Information Output Simple mode 2 State information output 1 indicates a lockout condition. State information output 2 indicates a muted condition. Functions and Features Wiring The grey (state information output 1) and grey/black (state information output 2) wires must be connected individually to the device inputs.
2-8 State Information Output How to change the mode 2 This can be changed on the SL-V or through the SL-VH1S. Functions and Features Making changes on the SL-V (1) Turn OFF the power to the SL-V. (2) Open (completely disconnect) the interlock mode selection input (pink wire on the transmitter), turn OFF the muting input 1 (light blue wire on the receiver) and muting input 2 (light blue/black wire on the receiver), and then turn ON the power to the SL-V again.
2-9 Alert Output The alert output is a NON-SAFETY-RELATED function. The amount of light being received decreases as build-up collects on the surface of the SL-V or as machine vibrations cause the beam axes to misalign. If the received light decreases enough, the machine may suddenly stop because the OSSD turns to an OFF state due to beam interruption. The alert output simply informs external, non safety-related devices that the amount of received light is decreasing.
2-9 Alert Output Time chart 2 140% Functions and Features SL-V Amount of receiving light 100% 0% T1 T1 ON (1) OFF Alert output ON (2) OFF T2 T2 T1: Less than alert monitoring time T2: Alert monitoring time plus 1 second (1) When using a PNP output type cable to connect to a PNP input device, or when using an NPN output type cable to connect to an NPN input device (2) When using a PNP output type cable to connect to an NPN input device, or when using an NPN output type cable to connect to a PNP i
2-10 Clear/Blocked Output The Clear/Blocked output is a NON-SAFETY-RELATED function. This output simply informs the external devices (non safety-related devices) whether the beam axes are clear or blocked. (“Clear” means no interruptions in the detection zone, “Blocked” means there is an interruption in the detection zone.) This output is NOT synchronized with the OSSD operation.
2-10 Clear/Blocked Output Time chart 2 SL-V No interruption Functions and Features Interruption ON Wait input OFF ON (1) OFF Clear/Blocked output ON (2) OFF 200 ms max. 200 ms max.
2-11 Temporary Suspension of Safety Function Muting function 2 Functions and Features The muting function is used to temporarily suspend the SL-V's safety functions while the SL-V receives a signal from muting devices (such as sensors or switches). Before this function can be used, the outputs from the muting devices must be connected to the muting input terminal on the SL-V. In addition, the SL-VH1S provides the user with the opportunity to select the beam axes to be muted condition.

A-1 Troubleshooting Error name EDM error Communication error12 EDM input is not connected to the external device correctly. Rewire the EDM correctly. "Examples of Wiring" (page 4-5) When EDM function is not used, EDM input and AUX are not connected correctly. Rewire the EDM and AUX correctly. "External Device Monitoring (EDM Function)" (page 215) Check for disconnections or shorts in the EDM input and AUX.
A-1 Troubleshooting Error name System error 22 Software configuration error A Cause Countermeasure The SL-V is affected by external noise. Check for noise around the SL-V installation location and cables. The SL-V is broken. Replace the SL-V. The communication cable is not connected correctly. Connect the communication cable correctly. "Examples of Wiring" (page 4-5) The communication cable is disconnected. Check whether the connectors are loose or disconnected.
A-1 Troubleshooting If the SL-V is not in the lockout condition If the OSSD is not functioning normally, perform the following measures regardless of whether the display lights indicate that the SL-V is in a lockout condition or not. Error name All Indicators are OFF including the OSSD indicator. Only the OSSD indicator lights in red. Cause Countermeasure Adjust the power supply voltage to be within the range of The power is not turned ON or the power supply specifications.
A-2 Checklist Checklist before operation You are fully responsible for performing the risk assessment on your machine application, taking into account performing maintenance and inspections, which are critical factor for appropriate risk assessment. In addition, it is a responsibility for the responsible personnel to train the machine operators regarding inspection and maintenance of the machine and the SL-V.
A-2 Checklist The two of OSSD outputs provided in the SL-V are both used as a safety-related machine control system. The polarity is not reversed with the connection to the power supply. In case of using PNP output type cable, the OSSD is not short-circuited to +24V, and the load is (3) Pre-check test while the machine is stopped. You should do the following pre-check test with the test piece in order to make sure the operation of the SL-V while the machine is stopped.
A-2 Checklist (4) Pre-check test while the machine is operating. The purpose of this pre-check test is to make sure that the machine (hazards) stops its operation. This test must be done after you completely make sure that there is nobody in the hazardous zone. The machine stops if the test piece is present in the detection zone. It is recommended to try three locations of test piece: near the transmitter, near the receiver, and in the central area of the detection zone.
A-2 Checklist (1) Additional inspection items The actual distance between the hazardous zone or hazards and the SL-V still keeps greater than the SL-V-M-NOA-E A-11 A Appendix calculated safety distance. When the reduced resolution function is applied, the safety distance is accurately calculated based on the enlarged detection capability, and the SL-V is installed at a distance greater than or equal to the minimum safety distance away from the hazardous zone or hazard.
