chine interface), which controls the OSSD outputs. All other receivers in the cascade must be set for trip mode and 2-channel
EDM (factory default settings).
The settings on the first receiver then determine trip or latch mode and 1- or 2-channel EDM/aux. output, and this is the only
receiver that requires a reset following a latch condition.
One or more areas within any cascaded EZ-SCREEN sensor pair can be blanked out, just as with other EZ-SCREEN
SLS light screens. Blanking for each sensor pair within a cascade, if required, must be programmed separately. See "Fixed
Blanking " on page 39 .
Configure each cascaded system before operating the system in a production environment.
Before configuration, install all emitters and receivers per " Installation Instructions " on page 21 and "Cascade" on page 69 .
The last receiver must be terminated either with a terminator plug or by connecting two closed mechanical contacts
(see " Emergency Stop Buttons and Rope/Cable Pulls " on page 79 and " Positive-Opening Interlocking Safety Switches " on
page 81 ).
WARNING:
Use a scan code
If you do not use a scan code, a receiver can synchronize to the signal from the wrong emitter, re-
ducing the safety function of the light curtain and creating an unsafe condition that could result in
serious injury or death.
Configure adjacent systems to use different scan codes (for example, set one system to use scan
code 1 and the other system to use scan code 2). Perform a trip test to confirm the light curtain
function.
Perform the following procedure only on the first receiver in the cascade (closest to the machine interface).
Configure for Cascaded Operation
8.6.1
From either normal operation or a power OFF condition, set the second and fifth DIP switches (RR and T/L) both to
the left (RR and T position).
1.
Set the third and fourth DIP switches (the second T/L and RR) both to the right (L and OFF position). The first and
sixth DIP switches are not part of this process. Do not move them to match this figure.

The receiver should be in a lockout condition or the power is off.
If the power is off, apply power.
If the receiver is in a lockout condition, perform a valid reset sequence (close the reset switch for 0.25 to 2
seconds, then reopen).
Coming out of lockout or during startup, the DIP switch configuration will be recognized as Cascaded Teach Mode, in-
dicated by the following:
The first receiver display shows: For no e-stop connected (“4C,” “3C,” or “2C” on); for an e-stop with closed
contacts (“4CE,” “3CE,” or “2CE” on); or for an e-stop with open contacts (“4CE,” “3CE” or “2CE” flashing)
The last cascaded receiver display shows: For a terminator connected (“1C” on); for an e-stop with closed
contacts (“1CE” on; or for an e-stop with open contacts (“1CE” flashing)
All other receivers display “1C” on
All receiver Zone indicators are off
All receiver amber reset indicators are off
All receiver Status indicators are red

To enable and exit Cascade Teach Mode, reconfigure the DIP switches for normal operation.
