QuickStart Guide
Components and Specifications
2.6 Specifications, continued
Supply Voltage (Limit Values) Emitter: 12 to 30V dc
Receiver Analog Current Models: 12 to 30V dc
Receiver Analog Voltage Models: 15 to 30V dc
Supply Power Requirements Emitter/Receiver Pair (Exclusive of Discrete Load): Less than 9 watts
Power-up delay: 2 seconds
Teach Input (Receiver Gray Wire) Low: 0 to 2 volts
High: 6 to 30 volts or open (input impedance 22 K ohms)
Two Discrete Outputs Solid-State NPN or PNP (current sinking or sourcing)

Protected against false pulse on power-up and continuous overload or short circuit.
Two Analog Outputs Voltage Sourcing: 0 to 10V (maximum current load of 5 mA)
Current Sourcing: 4 to 20 mA (maximum resistance load = (V
supply
–3) / 0.020)
Serial Communication Interface EIA-485 Modbus RTU (up to 15 nodes per communication ring)
RTU binary format
Baud Rate: 9600, 19.2K or 38.4K
8 Data Bits, 1 Stop Bit, and Even, Odd, or 2 Stop Bits and No Parity
Scan Time Scan times depend on scan mode and sensor length. Straight scan times range from 2.8 to 26.5
milliseconds. See Figure 1-7 for all combinations.
Status Indicators Emitter: Red Status LED
ON Red — Status OK
Flashing at 1 hz — Error
Receiver:
7 Zone Indicators
Red — Blocked channels within zone
Green — All channels clear within zone
3-digit 7-segment indicators for measurement mode / diagnostic information (see Section 1.4)
Sensor Status Bi-Color Indicator LED
Red — Hardware Error or Marginal Alignment (see Section 1.4)
Green — OK
Modbus Activity Indicator LED: Yellow
Modbus Error Indicator LED: Red
System Configuration
(Receiver Interface) 6-position DIP switch: Used to set scanning type, measurement modes, analog slope, and
discrete output 2 function (see Section 4.1). Alternate software GUI interface provides additional
options; see Section 1 and Section 5 of the full manual (p/n 130426).
Push Buttons (Receiver Interface) Two momentary push buttons for alignment and gain level selection.
Connections
Serial communication: The receiver uses a PVC-jacketed, 5-conductor 22-gauge quick-
disconnect cable, 5.4 mm diameter.
Other Sensor connections: 8-conductor quick-disconnect cables (one each for emitter and
receiver), ordered separately; see Section 2.2 for available lengths (may not exceed 75 meters
long), PVC-jacketed cables measure 5.8 mm diameter, have shield wire; 22-gauge conductors.
Construction Aluminum housing with clear-anodized finish; acrylic lens cover
Environmental Rating IEC IP65
Operating Conditions Temperature: –40° to +70° C (–40° to 122° F)
Maximum relative humidity: 95% at 50° C (non-condensing)
