Instruction Manual
Overview
Receiver Interface Status Indicators
The receiver has three status indicators: green/red System
Status, yellow Modbus Activity, and red Modbus Error. The
following table lists the indicator states.
Receiver Interface Status Indicators
LED Indicator Color Explanation
System Status Green System is OK
Red Marginal Alignment or Hardware
Error; check 3-digit display*
Modbus
Activity Yellow ON
or Flashing Activity detected on the Modbus
communication channel
Modbus Error Red Communication Error: Check
cabling or Modbus master
controller
* Display shows “c”: See Section 4.5.
Display shows only numbers: Low Gain/Marginal Alignment condition.
See Section 4.5.
1.5 Receiver Gray (Remote Teach) Wire
The receiver gray (remote teach) wire is used to electronically
emulate the receiver push button functions (see Section 4.5) via
a process controller, to disable the DIP switches for security, or
to provide a gate input to initiate sensor scanning. Connect a
normally open switch between the receiver’s gray wire and dc
common, or connect the gray wire to a digital input (PLC) and
pulse the wire as indicated in Figure 1-5.
NOTE: A low level is 0 to 2 volts and a high level is 10 to 30
volts or circuit open. Input impedance is 22kΩ.
Remote TEACH/Gate in the System Config view of the PC
interface Setup screen (Section 5.8) determines the functionality
of the receiver gray wire, as follows.
• Disabled: (selected via the PC interface only) the remote
wire has no function (regardless of whether it is low or high).

Access Alignment Mode “A” appears on 3-digit display
Access Blanking Mode
From Alignment Mode:
“n” appears on 3-digit display, along with number of
blocked beams
Exit Blanking Mode
“A.” appears on 3-digit display (sensor returns to
alignment mode with blanking enabled)
Exit Alignment Mode Sensor returns to run mode

Access Gain Mode
From Run Mode:
“L” appears on 3-digit display, along with number “1” or
“2”, to designate gain level
Toggle Between Gain Settings Number changes from number “1” to “2”, back to “1”, etc.
Save Gain Level and Exit
When correct level is displayed: Gain level is configured:
“1” = High-excess-gain setting
“2” = Low-contrast setting
Sensor returns to run mode

Receiver Interface
Enable/Disable
The factory default is Receiver Interface enabled.
Four-pulsing the remote line saves the current settings
and disables the interface (the sensor continues to
operate using the saved settings; changes made to the
DIP switch will have no effect).
Repeating the process enables the Receiver Interface so
that settings can be changed.
