IMPORTANT When the Safety Input Channel Mode is set to Test Pulse from Test Out,
specify the test output to use for the test source and set the Test Output
Channel Mode of the test output to Pulse Test Output.
Value
0 to 126 ms Sets the OFF/ON delay time.
(in increments of
6 ms)
0 to 126 ms Sets the ON/OFF delay time.
(in increments of
6 ms)
Not Used The safety input is not used.
(External input device not connected.)
Test Pulse from Specifies connecting a device with a
Test Output contact output in combination with a test
output. When this mode is selected, select
the test output to use for the test source
and then set the test output mode to Pulse
Test Output. When these settings are
made, contact between the input signal
line and the power supply (plus) and short
circuits with other input signal lines can be
detected.
Specifies connecting a safety device with

Single Channel Specifies using Single Channel Mode. If
Single Channel is selected, the safety
input that would be paired for the dual
channel parameter will also be set to
Single Channel Mode.
Dual Channel Specifies using the Dual Channel
Equivalent Equivalent Mode with a paired safety
input.
Dual Channel Specifies using Dual Channel
Complementary Complementary Mode with a paired safety
input.
