Introduction
Configure Local Safety Inputs
The controller has 16 local safety inputs that support the following features.
• Input circuit diagnosis — Test pulse sources can be used to monitor
internal circuits, external devices, and external wiring.
• Input on- and off-delays — You can set input time filters of 0...126 ms in
multiples of the controller cycle time. Setting input on- and off-delays
helps reduce the influence of chattering and external noise.
• Dual Channel mode — You can set Dual Channel mode for pairs of
related local inputs. When Dual Channel mode is set, time discrepancies in
data changes or input signals between two paired local inputs can be
evaluated.
Follow these steps to configure local safety inputs.
1. Right-click the SmartGuard controller and choose Properties.

IMPORTANT
Input on- and off-delays must be added to the I/O response time. This
will affect the system reaction time calculations.
Refer to SmartGuard Controllers Safety Reference Manual, publication
1752-RM001, for information on calculating reaction times.
