Chapter 4          Safety Function

Multiple Scan

When multiple scan is enabled, the response time increases by approximately 
33%. See the diagnostic property 3.30 in the Connected Components 
Workbench software for the actual response time.

Not applicable for 450L PAC safety light curtains.

Short Interruption Time

The 450L-E safety light curtain can be configured to ignore interruptions up to 
174 ms. This value is added to the response time. See the diagnostic property 
3.30 in the Connected Components Workbench software for the actual 
response time.

Not applicable for 450L PAC safety light curtains.

When the interference rejection feature is used and configured using software, the response time for both systems is derived from the system that has the largest response time. For 
example, enabling interference rejection on two systems where one system is 1200 mm (47.24 in.) finger resolution and the other system is 1650 mm (64.96 in.) hand resolution would result 
in both systems having a response time of 57 ms.
