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

Residual Ripple± 10% maximum
Supply CurrentEmitter: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)

7-Segment Diagnostic indicator (1 digit) - indicates proper operation, scan code, or error code
Wavelength of Emitter ElementsInfrared LEDs, 850 nm at peak emission
Remote Test InputTest 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.

Low Signal: 0 to 3V dc



Input Current: 35 mA inrush, 10 mA max.
Controls and AdjustmentsScan 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 TimeDependent 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 TimeBlocked 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 InputReset 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 OutputA monitored or non-monitored (selectable), current-sourcing (PNP), solid-state output



Rated Current: 10 mA to 360 mA at 24V dc

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 IndicatorsYellow 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
