Instruction Manual
2.5 Specifications
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 (see Section 3.7.3).
Monitored devices must respond within 200 milliseconds of an output change.
Outputs
(See Warnings on page 33.)
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.)
Capable of the Banner “Safety Handshake” (see Section 1.1).
ON-State voltage: ≥Vin-1.5V dc
OFF-State voltage: 1.2V dc max.
Max. load resistance: 1000 ohm
Max. load capacitance: 0.1µF
Controls and Adjustments
Emitter:
Scan code selection: 2-position switch (code 1 or 2). Factory default position is 1.
Receiver:
Scan code selection: 2-position switch (code 1 or 2). Factory default position is 1.
Trip/latch output selection: redundant switches. Factory default position is L (latch).
EDM/MPCE monitor selection: redundant switches select between 1- or 2-channel
monitoring. Factory default position is 2.
Supply Voltage (V in)
24V dc ±15%, 10% maximum ripple
Emitter: 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; see Section 3.5)
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
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
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 de-activates Test mode and allows the emitter to operate normally. TEST1 and
TEST2 are factory jumpered. (See Section 3.7.4 for more information.)
Emitter/Receiver Operating Range
(See Caution on page 6.)
Short-range models: 0.8 m to 20 m (2.6' to 65')
Long-range models: 15 m to 70 m (49' to 230')
Range decreases with use of mirrors and/or lens shields; see Section 2.2.
Beam Spacing
(See dimension drawing, Figure 2-1,
for beam locations.) Model SG...4-300: 300 mm (11.8")
Model SG...3-400: 400 mm (15.7")
Model SG...2-500: 500 mm (19.7") Model SG...3-533: 533.4 mm (21")
Model SG...2-584: 584.2 mm (23")
Beam Diameter 25 mm (1")
Ambient Light Immunity > 10,000 lux at 5° angle of incidence
Strobe Light Immunity Totally immune to one Federal Signal Corp. “Fireball” model FB2PST strobe
Emitter Elements Infrared LEDs, 880 nm at peak emission
