Setting Description
Start mode
Can only be selected for 8-pin Rx plug-in or for 5-pin Rx plug-in with I/O cascading plug-in.
The selections are:
• Automatic start – If the safety light curtain is clear, the OSSD outputs turn ON. This mode
applies to power-up and after power-up.
• Power up Start Interlock – Upon power-up, the start must be pressed and released within a
window of 50…5000 ms. After power-up, the OSSD output operates automatically.
• Manual Start – Upon power-up and after the OSSDs turn OFF, the start must be pressed and
released within a window of 50…5000 ms. The OSSD outputs energize on the trailing edge
of the start signal.
• Manual Start with Off Function – Upon power-up and after the OSSDs turn OFF, the start
must be pressed and released within a window of 50…5000 ms. The OSSD outputs
energize on the trailing edge of the start signal. The OSSD outputs can also be turned OFF
with the start.
Start release
Start release function can be selected with either the 8-pin Rx plug-ins or the 5-pin plug-ins
with an I/O plug-in. Start Release and EDM cannot be ON simultaneously.
When the light curtain is clear, the OSSD outputs energize on the leading edge of the start
release input.
EDM enable
EDM function can only be selected with 8-pin Rx plug-ins. Start Release and EDM cannot be
ON simultaneously.
The EDM input must change state within the selected time. If the EDM signal does not change
state, the OSSD outputs de-energize and the light curtain is locked out; a lockout requires a
power cycle to clear the fault.
• Min: 50 ms
• Max: 1275 ms
• Increment: 5 ms
• Default: 300 ms (when enabled)
Operating range Allows you to set the operating range to either long range (default) or short range.
Beam coding
Enables beam coding. Beam coding helps prevents interference from neighboring light
curtains. The response time increases if beam coding is selected.
Interference
rejection
Enables interference rejection. Interference rejection is an enhancement to beam coding. In
applications where enabling beam coding alone does not mitigate interference, the
interference rejection feature can be enabled to alter the scan pattern to restrict stray light
from a neighboring 450L-E safety light curtain from affecting operation. The response time
increases if interference rejection is selected, however, configuring in Connected
Components Workbench, as opposed to by DIP switch, refines the settings and ensures that
the most appropriate scan pattern is used, which can be less than the response time derived
for DIP switch configuration - refer to
Table 18 on page 49 and Table 19 on page 50 for
response times set by DIP switch or Connected Components Workbench.
External test
enables
Enables an input to either turn the OSSD outputs ON or OFF.
