SAFETYLIGHT SCREENS Supply Voltage at the Device* 24V dc ±15% (SELV), ± 10% max. ripple Supply CurrentEmitter: 100 mA max. Receiver: 275 mA max., exclusive of OSSD1 and OSSD2 loads (up to an additional 0.5A each) Response Time 9 to 56 millesconds Cascade Safety Stop Interface (CSSI): Test Mode is activated either by applying a low signal (less than 3V dc) to emitter TEST #1 terminal for a minimum of 50 milliseconds, or by opening a switch connected between TEST #1 and TEST #2 for a minimum of 50 milliseconds. Beam scanning stops to simulate a blocked condition. A high signal at TEST #1 deactivates Test Mode. (See p/n 40 milliseconds max. Remote Test Input(Optional – available only on model SLSE..-..Q5 emitters)
EZ-SCREEN ® PICO-GUARD ™ 112852 for more information.) High signal: 10 to 30V dc
MICRO-SCREEN ® Low signal: 0 to 3V dc Input current: 35 mA inrush, 10 mA max.
MINI-SCREEN ® Wavelength of Emitter Elements Infrared leds, 950 nm at peak emission
EZ-SCREEN ® EDM Input +24V dc signals from external device contacts can be monitored (one-channel, two-channel or no monitoring) via EDM1 and EDM2 terminals in the receiver. Monitored devices must respond within 200 milliseconds of an output change.
TYPE 2 High signal: 10 to 30V dc at 30 mA typical Low signal: 0 to 3V dc Dropout time: 200 milliseconds max. Reset Input The 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 Safety Outputs 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: â‰¥ Vin-1.5V dc OFF-State voltage: 1.2V dc max. (0-1.2V dc) Max. load capacitance: 1.0 µF Max. load inductance: 10 H Leakage current: 0.50 mA maximum Cable resistance: 10 maximum OSSD test pulse width: 100 to 300 microseconds OSSD test pulse period: 5 to 27 milliseconds (varies with number of beams) Switching current: 0-0.5 A Controls and AdjustmentsEmitter:Scan Code selection: 2-position switch (code 1 or 2). Factory default position is code 1. 2-position switch (code 1 or 2). Factory default position is code 1. Receiver: Scan Code selection: Trip/Latch Output selection: Redundant switches. Factory default position is T (Trip). EDM/MPCE monitor selection: 2-position switch selects between 1- or 2-channel monitoring.Factory default position is 2. Reduced Resolution (2-beam Floating Blanking): Redundant switches to enable. Factory default is OFF. Short Circuit Protection All inputs and outputs are protected from short circuits to +24V dc or dc common* Electrical Safety Class(IEC 61140: 1997) III Safety Rating Type 4 per IEC 61496-1, -2; Category 4 per ISO 13849-1 (EN 954-1) Operating Range14 mm models: 0.1 m to 6 m 30 mm models: 0.1 m to 18 mRange decreases with use of mirrors and/or lens shields: Lens shields – approximately 10% less range per shield. Glass-surface mirrors – approximately 8% less range per mirror.See Accessory section for more information on a specific mirror, page 204. Ambient Light Immunity > 10,000 lux at 5° angle of incidence Effective Aperture Angle (EAA) Meets Type 4 requirements per IEC 61496-2, ± 2.5° @ 3 m
*The external voltage supply must be capable of buffering brief mains interruptions of 20 milliseconds, as specified in IEC/EN 60204-1.
