Description
Any of the following five modes can be selected according to the external input device.
Not Used The corresponding test output is not used.
Standard Output Specifies connecting to the input for a muting lamp or PLC. Used
as a monitor output.
Pulse Test Output Specifies connecting a device with a contact output in combination
with the safety input.
Power Supply Specifies connecting to the power supply terminal of a safety sen-
Output sor. The voltage supplied from the test output to the I/O power
supply (V, G) is output.
Muting Lamp Specifies a muting lamp output.
Output (terminal
When the output is ON, disconnection of the muting lamp can be
T3 only)
detected.
Sets the output state of the test output when a communications error occurs.This param-
eter is enabled when the Test Output Channel Mode is set to Standard Output or Muting
Lamp Output.
Supported.
Supported.
This setting is valid when Test Output Mode is set to Muting Lamp Output.
Description
Any of the following three modes can be selected according to the external input device.
Not Used The safety output is not used. (External output device not connect-
ed.)
Safety Specifies not outputting the test pulse when the output is ON. Con-
tact between the output signal line and the power supply (positive)
when the output is OFF and ground faults can be detected.
Safety Pulse Outputs the test pulse when the output is ON. Contact between the
Test output signal line and the power supply, and short circuits with other
output signal lines can be detected.
The consistency between signals on two channels can be evaluated. Either of the fol-
lowing settings can be selected.
Single Channel Specifies using Single Channel Mode. When Single Channel is set,
the safety output that would be paired for the dual channel parame-
ter is also set to Single Channel Mode.
Dual Channel Specifies using Dual Channel Mode. When both of the safety out-
puts to be paired are normal, the outputs can be turned ON.
The OFF status is held for at least the output error latch time (0 to 65,530 ms, in incre-
ments of 10 ms) when the individual safety output status turns OFF.
Supported.
Supported.
