Enclosure Materials: Extruded aluminum housing with yellow polyester powder or nickel-plated finish and well-sealed, rugged die-cast zinc end caps, acrylic lens cover, copolyester access cover
SAFETYLIGHT SCREENS Rating: IEC IP65 Operating ConditionsTemperature: 0° to +55° C Relative humidity: 95% (non-condensing) Status IndicatorsEmitter:One Bi-color (Red/Green) Status Indicator –
EZ-SCREEN ® indicates operating mode, Lockout or power OFF condition 7-segment Diagnostic Indicator (1 digit) – indicates proper operation, scan code or error code
PICO-GUARD ™ Receiver:Yellow Reset Indicator –
MICRO-SCREEN ® indicates whether system is ready for operation or requires a reset Bi-Color (Red/Green) Status Indicator – indicates general system and output status
MINI-SCREEN ® Bi-Color (Red/Green) Zone Status Indicators – indicates condition (clear or blocked beam) of a defined group of beams
EZ-SCREEN ® TYPE 2 7-Segment Diagnostic Indicator (3-digit) – indicates proper operation, scan code or error code, total number of blocked beams Mounting Hardware Emitter and receiver each are supplied with a pair of
swivel end-mounting brackets. Models longer than 900 mm also include a swivel center-mount bracket. Mounting brackets are 8-gauge cold-rolled steel, black zinc finish. Shock and Vibration EZ-SCREEN systems have passed vibration and shock tests according to IEC 61496-1. This includes vibration (10 cycles) of 10-55 Hz at 0.35 mm single amplitude (0.70 mm peak-to-peak) and shock of 10 g for 16 milliseconds (6,000 cycles).

Grid & Point Specifications
Supply Voltage (V in) 24V dc ±15%, 10% max. ripple Supply CurrentEmitter: 150 mA max. Receiver: 500 mA max., exclusive of OSSD1 and OSSD2 loads (up to an additional 0.5A each) Short Circuit Protection All inputs and outputs are protected from short circuits to +24V dc or dc common(except Emitter AUX
power connections) Response Time 24 milliseconds or less from interruption of
light grid beam to safety outputs going to OFF-state Safety Rating Type 4 per IEC 61496-1, -2; Category 4 per ISO 13849-1 (EN 954-1)
EDM Input +24V dc signals from external device contacts can be monitored (single-channel, dual-channel or no monitoring) via EDM1 and EDM2 terminals in the receiver. Monitored devices must respond within 200 milliseconds of an output change. Reset Input The Reset input must be high (10 to 30V dc at 30 mA) for 0.25 to 2 seconds and then low (less than 3V dc) to reset the receiver. Remote Test Input Safety Outputs Test mode is activated either by applying a low signal (less than 3V dc) to emitter TEST1 terminal for a minimum of 50 milliseconds, or by opening a switch connected between TEST1 and TEST2 terminals for a minimum of 50 milliseconds. Beam scanning stops to simulate a blocked condition. A high signal
(10 to 30V dc, 35 mA inrush, 10 mA max.) at TEST1 terminal deactivates Test mode and allows the emitter to operate normally. TEST1 and TEST2 are factory jumpered. Two diverse-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.) ON-State voltage: ≥ Vin-1.5V dc OFF-State voltage: 1.2V dc max. Max. load resistance: 1000 ohm Max. load capacitance: 0.1 µF Controls and AdjustmentsEmitter:Scan code selection: 2-
