signal outputs
TM0 and TM1 as 
clock outputs
Leuze electronic
If you configure outputs TM0 and TM1 as signal outputs, you thereby control, e.g., a non-safe
PLC or signal units.
Make certain that the GND potential of the signal receiver is the same as the GND potential
of the safety module.
The non-safety-relevant signal outputs are designed as digital semiconductor outputs.
ATTENTION: Module defect
The signal outputs can be destroyed by incorrect wiring.
Do not connect the signal outputs in parallel.
•
Prevent feedback to the signal outputs.
•
Configure the two outputs TM0 and TM1 as signal outputs by making the following settings in
the configuration editor in MSIsafesoft. The signal outputs can only be configured together.
For TM0 to TM1, set the "Configuration" parameter to the value "Signal output - M0 to M1".
•
The signal outputs are linked in the connection editor of the MSIsafesoft configuration soft-
ware.
You can find further information on linking the signal outputs in the connection editor in the
help system of the MSIsafesoft configuration software.
If you configure outputs TM0 and TM1 as clock outputs, they will support cross-circuit detec-
tion at the inputs of the safe extension module.
See chapter "Error detection" on page 21.
If you use configurable inputs/outputs IO0 to IO3 as inputs, it is mandatory that cross-circuit
detection be implemented with the extension module, i.e., the affected inputs must be supplied
via clock outputs TM0 or TM1 of the extension module.
See Chapter "Safe inputs" on page 38.
If you use configurable inputs/outputs IO0 to IO3 as outputs, configuring TM0 and TM1 as
clock outputs results in an error.
Configure the two outputs TM0 or TM1 as clock outputs by making the following settings in the
safe configuration editor. The clock outputs can only be configured together.
For IO0 to IO3, set the "Signal configuration" parameter to the value "Configured as safe

The test pulses output at outputs TM0 and TM1 (if the configuration settings have been made
accordingly) are used for cross-circuit detection at the inputs of the extension module. The out-
put test pulses T0 and T1 are phase-shifted with respect to one another.
To implement cross-circuit detection, the relevant safe inputs must be configured accordingly
using the configuration editor in MSIsafesoft.
