Chapter 5 Configure the Module in a GuardLogix Controller System
3. Assign the Point Mode.
4. Assign a Test Source for each safety input on the module you want to pulse
test.
5. Assign the Input Delay Time, Off -> On (0…126 ms, in increments of
6 ms).
Filter time is for OFF to ON transition. Input must be high after input
delay has elapsed before it is set logic 1. This delay time is configured per
channel with each channel specifically tuned to match the characteristics
of the field device, for maximum performance.
6. Assign the Input Delay Time, Off -> On (0…126 ms, in increments of
6 ms).
Filter time is ON to OFF transition. Input must be low after input delay
has elapsed before it is set logic 0. This delay time is configured per channel
with each channel specifically tuned to match the characteristics of the
field device, for maximum performance.
Choose Description
Not Used The input is disabled. It remains logic 0 if 24V is applied to the input
terminal.
Safety Pulse Test Pulse testing is performed on this input circuit. A test source on the
POINT Guard I/O module
must be used as the 24V source for this
circuit. The test source is configured by using the test source
pull-down menu. The pulse test will detect shorts to 24V and
channel-to-channel shorts to other inputs.
Safety A safety input is connected but there is no requirement for the POINT
Guard I/O module to perform a pulse test on this circuit. An example
is a safety device that performs its own pulse tests on the input wires,
such as a light curtain.
Standard A standard device, such as a reset switch, is connected. This point
cannot be used in dual-channel operation.
Choose Description
None
If pulse testing is performed on an input point, then the test source
that is sourcing the 24V for the input circuit must be selected.
If the incorrect test source is entered, the result is pulse test failures
on that input circuit.
