Banner WorldwideEZ-SCREEN Low-Profile Safety Light Curtain Systems with Integral Muting
Overview
- Low-profile, compact package for smaller production machines, yet robust enough for large power presses
- Creates a screen of synchronized, modulated infrared sensing beams that extend from end to end of the housing (no "dead zone")
- Built-in muting function, no third box required. Capable of two or four mute device/sensor hookup options
- Seven different, predefined, muting configuration options, including Bypass, Mute-Dependent Override, Mute Enable, and Mute-cycle time extensions (4 seconds) for "L"-style cell exit applications
- Selectable monitored/non-monitored Mute Lamp, Reset Status, and two OSSD Status Outputs to EZ-LIGHT (or other indicating devices) with RD cordset and accessory end-cap mounting bracket
- Optional CSM Muting Splitter Cordset provides easy set up, less wiring, lower installation costs by providing a complete QD connectorized solution
- Status, Reset, Zone, Mute Device and Diagnostic indicators and displays tell the number and location of beams blocked and provide detailed diagnostics minimizing downtime and troubleshooting
- Set up can be performed without a PC, hand-held programmer, or other device; and DIP switch configuration features many of the same functions as a standard EZ-SCREEN Low Profile
- 100 mm to 7 m (4" to 23') sensing range
- Highly immune to EMI, RFI, ambient light, weld flash and strobe light
Product Specifications
| Supply Voltage at the Device | 24V dc ±15% (use a SELV-rated power supply according to EN IEC 60950). (The external voltage supply must be capable of buffering brief mains interruptions of 20 ms, as specified in IEC/EN 60204-1) |
|---|---|
| Residual Ripple | ± 10% maximum |
| Supply Current | Emitter:60 mA max. exclusive of Fault Out load Receiver:150 mA max., exclusive of OSSD1 and OSSD2 loads (up to additional 0.5A each) and Aux Out load (up to 0.25 A) |
| AUX/Fault Output Switching Capacity | Current-sourcing (PNP) solid-state output, 24V dc at 250 mA max. |
| Status Indicators | One bi-color (Red/Green) Status Indicator - indicates operating mode, lockout or power OFF condition 7-Segment Diagnostic indicator (1 digit) - indicates proper operation, scan code, or error code |
| Wavelength of Emitter Elements | Infrared LEDs, 850 nm at peak emission |
| Remote Test Input | Test mode is activated either by applying a low signal (less than 3V dc) to emitter Test/Reset terminal for a minimum of 50 milliseconds, or by opening a switch connected between Test/Reset and +24V dc for a minimum of 50 milliseconds. Beam scanning stops to simulate a blocked condition. A high signal at Test/Reset deactivates Test mode. High Signal: 10 to 30V dc Low Signal: 0 to 3V dc Input Current: 35 mA inrush, 10 mA max. |
| Controls and Adjustments | Scan Code Selection: 2-position switch (code 1 or 2). Factory default position is code 1. Test/Reset: 2-position switch. Factory default position is Reset. Invert Display: 2-position switch. Factory default position is OFF (standard display). Fault: 2-position switch. Factory default position is OFF. |
| Response Time | Dependent on number of sensing beams; see models table (manual p/n 150216) for number of beams and response time. |
| EDM Input | +24V dc signals from external device contacts can be monitored (one-channel or no monitoring) via EDM1 terminal in the receiver. High Signal: 10 to 30V dc at 30 mA typical Low Signal: 0 to 3V dc |
| Output Signal Switching Devices (OSSDs) | Two redundant solid-state 24V dc, 0.5 A max. sourcing OSSD (Output Signal Switching Device) safety outputs. (Use optional interface modules for ac or larger dc loads.) Capable of the Banner Safety Handshake. ON-State voltage: > Vin-1.5V dc OFF-State, maximum allowed voltage: 1.7V dc max. Max. load capacitance: 1.0 μF Min. load inductance: 10 H Leakage Current: 0.50 mA max. OSSD test pulse width: 100 to 300 microseconds typical OSSD test pulse period: 10 ms to 22 ms (varies with number of beams) Switching Current: 0-0.5 A |
| Auxiliary Output Switching Capacity (OSSD/Fault) | Current-sourcing (PNP) solid-state output, 24V dc at 250 mA max. |
| Recovery Time | Blocked to Clear (OSSDs turn ON; varies with total number of sensing beams and whether Sync beam is blocked): 14 mm Models: 109 ms to 800 ms for Beam 1 (Sync Beam); 33ms to 220 ms for all other beams 25 mm Models: 81 ms to 495 ms for Beam 1; 25 ms to 152 ms for all other beams |
| Reset Input | Reset input must be high for 0.25 to 2 seconds and then low to reset the receiver High Signal: 10 to 30V dc at 30 mA typical Low Signal: 0 to 3V dc Closed Switch Time: 0.25 to 2 seconds |
| Mute Lamp Output | A monitored or non-monitored (selectable), current-sourcing (PNP), solid-state output Rated Current: 10 mA to 360 mA at 24V dc |
| External Remote Indicator Outputs | Current sourcing (PNP), solid-state, 24 Vdc outputs for the connection of remote indicator lamps such as EZLIGHTs. See EZ-LIGHT™ for EZ-SCREEN® Low Profile with Muting on page 98 for compatible EZ-LIGHTs and associated cordsets. Rated Current: 100 mA maximum at 24 Vdc |
| Controls and Adjustments | Scan Code selection: 2-position switch (code 1 or 2). Factory default position is code 1. Trip/Latch Output selection: Redundant switches. Factory default position is T (trip). Mute Lamp Monitoring: ON/OFF switch. Factory default position is ON. Reduced Resolution: Redundant switches. Factory default position is OFF. Aux./Fault: 2-position switch. Factory default position is Aux. Invert Display: 2-position switch. Factory default position is OFF (standard display). |
| Status Indicators | Yellow Reset Indicator - indicates whether the system is ready for operation or requires a reset Bi-color (Red/Green) Status indicator - indicates general system and output status Bi-color (Red/Green) Zone Status indicators - indicate condition (clear or blocked beam) of a defined group of beams 7-Segment Diagnostic indicator (1 digit) - indicates proper operation, scan code, error code, or total number of blocked beams Yellow Mute Device Input Indicators - indicates status of mute device inputs |

| Mounting Hardware | Emitter and receiver each are supplied with a pair of swivel end-mounting brackets and two swivel sidemount brackets. Models longer than 690 mm also include additional side-mount bracket(s) for center support. Mounting brackets are 8-gauge cold-rolled steel, black zinc finish. |
| Cables and Connections | See Cordsets on page 88 (manual p/n 150216) for recommended cables. If other cables are used with the EZ-SCREEN LPM, the user must verify suitability of these cables for each application. |
