3.4.8 FX3-XTDS I/O module
Overview
T
he FX3-XTDS module is an input/output expansion module with 8safety inputs and
4non-safety outputs. It has 2test pulse generators, one for test output XY1 and one for
test output XY2.
The FX3-XTDS module supports the following functions:
•
Monitoring of the connected safety devices
•
Forwarding of information at inputs I1 to I8 to the main module
•
Receipt of control signals from the main module and corresponding switching of
outputs
•
Outputs XY1 and XY2 can be used as either test outputs or non-safe outputs.
Important information
WARNING
Improper use of the non-safety outputs
The dangerous state may not be stopped or not be stopped in a timely manner in the
event of non-compliance.
►
Do not use the FX3-XTDS outputs for safety functions.
WARNING
Ine
ffectiveness of the protective device due to undetected short-circuits between the
test pulse generators
The dangerous state may not be stopped or not be stopped in a timely manner in the
event of non-compliance.
►
Configure the test outputs of the Flexi Soft expansion modules with test pulse
widths ≤4ms and a test pulse interval ≥200ms.
NOTE
If bo
th outputs XY1 and XY2 are used as non-safety outputs, then it is nevertheless
possible to connect a tested element to one of these inputs I1 to I8. However, this
element is marked red in the hardware configuration as a warning.
