3-3-1 Safety Input Functions
A test pulse with a specific period is output on the 24-VDC power line from a test output terminal to
detect wiring errors and failure of the externally connected device. The following parameters are also
used.
• Test pulse diagnosis
• Test source
• Test pulse mode
 Test Pulse Diagnosis
The Test Pulse Diagnosis setting determines whether to output a test pulse with a specific period
from the test output terminal. The parameter determines whether test pulse evaluation is used. This
parameter is set according to the type of external device that is connected to the safety input termi-
nal.
 Test Source
The Test Source setting determines the test output terminal to use when the Test Pulse Diagnosis
parameter is set to with Test Pulse. The test output terminal is automatically assigned by the Sys-
mac Studio, but it can be changed to any test output terminal.
 Test Pulse Mode
The Test Pulse Mode setting is used to output a test pulse that is suitable for the external device
when the Test Pulse Diagnosis parameter is set to with Test Pulse.
Test Pulse Evaluation
Setting Description
Without Test Pulse A test pulse from the test output terminal is not output for diagnosis. This setting is used
for safety devices with semiconductor outputs that diagnose the OSSD output them-
selves, such as safety light curtains, and for standard devices.
With Test Pulse A test pulse from the test output terminal is output for diagnosis. The mode of the test out-
put to use as the test source is selected according to the safety device that is connected.
Setting Description
Mechanical Contact The test pulse is connected to a device with mechanical contacts. The test output sig-
nal (pulse output) is input to the safety input terminal through the mechanical contact
device. The following can be detected: Contact of the input signal line with the positive
side of the power supply line, ground faults, and short-circuits to the other input signal
lines.
Single Beam Safety
Sensor
An OMRON E3ZS/E3FS Single-beam Safety Sensor is connected. A test signal for
Single-beam Safety Sensor diagnosis is output.
Non-contact Switch An OMRON D40A or D40Z Non-contact Door Switch is connected. Test signals for the
D40A or D40Z will be output.
Safety Mat/Safety
Edge
An OMRON UM Safety Mat or SGE Safety Edge (4-wire) is connected. A test signal for
Safety Mat/Safety Edge diagnosis is output.
