The I3 input can be used, at all times, to replace the coded actuator with a second
actuator. By activating this input, the device gets ready for programming mode with the
IN LED orange light fl ashing, it deactivates all the OS1, OS2, O3 and O4 outputs and
then releases the actuator. Keep the input active while inserting the second actuator.
Acquisition of the second actuator is confi rmed by the IN LED switching off and by
four fl ashes of the ACT LED. At this point, it is possible to deactivate the I3 input. The
device will automatically be brought to the restart state and the fi rst actuator is no
longer detected.
The second actuator will have to be adequately fi xed to the protective device as
explained in section MOUNTING INSTRUCTIONS.
This operation must not be carried out as a repair or maintenance operation. In the
case where the device stops working correctly, replace the entire device and not just
the actuator.
5.5 Reset input
The following error states due to a device external failure can be reset using the I3
input:
- a short circuit or overload of safety outputs (OS1 and OS2),
- short circuit between a safety output and the supply voltage,
- excessive misalignment between a safety device and a locked actuator.
5.6 Series connection with safety modules
It is possible to install several devices in cascade connection up to a maximum number
of 32 units, while maintaining safety category 4 / PL e according to EN ISO 13849-1
and SIL CL 3 integrity level according to EN 62061.
Check that the PFHd and MTTFd values of the system comprising the series connec-
tion of devices and the whole safety circuit meet the SIL/PL requirements prescribed
for the application.

When connecting the devices in series as described above, observe the following:
- Connect the inputs of the fi rst device in the chain to the power supply.
- The OS1 and OS2 safety outputs of the last device in the chain must be con-
nected to the safety circuit of the machine.
- Where a safety module is used, check that the properties of OS1/OS2 safety out-
puts are compatible with the safety module inputs (see section INTERFACING).
- Observe the limits of the output cable stray capacitance, as specifi ed in the
electrical data (see section TECHNICAL DATA).
- Check that the cascade response time fulfi lls the requirements of the safety
function to be obtained.
- The chain response time must be calculated taking into account the response
time of each device.
- When using Y-cables for series connection, special attention must be paid to
the fl owing currents, cable cross-sections and cable lengths in order to ensure
that the supply voltage of the components at the end of the series connection is
within the specifi ed electrical limits of the L300 during operation.
