Components and Specifications
Supply Voltage at the Device 24V dc ±15% (use a SELV-rated 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 (no load) 150 mA max., exclusive of OSSD1 and OSSD2 loads (up to an additional 0.5 A each) and Aux Out
load (up to 0.25 A)
Response Time Dependent on number of sensing beams; see models tables in Sections 2.1, 2.2, 7.2, and 7.3 for
number of beams and response time for each model.
CSSI Response Time
(SLPC.. cascade models only) Response time for a cascade receiver due to opening contacts at the cascade interface (CSSI): 40 ms
max (contacts must open for 60 ms minimum). See Section 7.5.
Recovery Time Blocked to Clear (OSSDs turn ON; varies with total number of sensing beams and whether
Sync beam is blocked):
Beam 1 (Sync Beam) All Other Beams
14 mm Models 109 ms to 800 ms 33 ms to 220 ms
25 mm Models 81 ms to 495 ms 25 ms to 152 ms
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 (see Section 3.5.3).
High Signal: 10 to 30V dc at 30 mA typical
Low Signal: 0 to 3V dc
Reset Input Reset input must be high for 0.25 to 2 seconds and then low to reset the receiver (see Section 4.3).
High Signal: 10 to 30V dc at 30 mA typical
Low Signal: 0 to 3V dc
Closed Switch Time: 0.25 to 2 seconds
2.7.3 Receiver Specifications
Supply Voltage at the Device 24V dc ±15% (use a SELV-rated 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 60 mA max., exclusive of Fault Out load
Fault Output Switching Capacity Current-sourcing (PNP) solid-state output, 24V dc at 250 ma max. (see Section 3.5.1)
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. (See Section 3.5.6 for more information.)
High Signal: 10 to 30V dc
Low Signal: 0 to 3V dc
Input Current: 35 mA inrush, 10 mA max.
Controls and Adjustments
(see Section 4.2) 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.
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
See Figure 1-3 for indicator locations and Section 4.4 for indicator conditions.
