Configure the Module in a GuardLogix Controller System Chapter 5
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
6ms).
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 that is 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
6ms).
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 that is tuned to match the characteristics of the field
device, for maximum performance.
Choose Description
Not Used The input is disabled. If 24V is applied to the input terminal, it
remains logic 0.
Safety Pulse Test Pulse tests are 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 detects 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 tests are 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.
