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.
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 out-
put themselves, 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 output to use as the test source is selected according to the safety device
that is connected.
l
Test Source
The Test Source setting determines the test output terminal to use when the Test Pulse Diagnosis
parameter is set to with T
est Pulse. The test output terminal is automatically assigned by the Sys-
mac Studio, but it can be changed to any test output terminal.
l
T
est 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.
Setting Description
Mechanical Con-
tact
The test pulse is connected to a device with mechanical contacts. The test output signal
(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
Door Switch
An OMRON D40A/D40Z Non-contact Door Switch is connected. Test signals for the D40A
or D40Z will be output.
Safety Mat/Safe-
ty Edge
An OMRON UM/UMA Safety Mat or SGE Safety Edge (4-wire) is connected. A test signal
for Safety Mat/Safety Edge diagnosis is output.
Dual Channel Evaluation
Safety input terminals can be used as dual channels (one pair). The dual channel evaluation evaluates
the data for two inputs to check for discrepancy.
