4. Type the input name into the I/O Comment field.
For this example, we typed EStop ChA.
5. Select the Channel Mode from the pull-down list based on the table below.
Channel Mode
Description
Not Used
The input channel is not connected to an external device. This is the default.
Test pulse from test output
Use this mode when you are achieving a Category 4 input circuit. This mode assumes that you have connected your input device to a Pulse Test
Source, and then wired to this input terminal. This enables detection of short circuits with the power supply line (positive side), earth faults, and
short circuits with other input signal lines (channel-to-channel shorts). The controller must know that the input signal is being pulse-tested, or
nuisance trips may occur.
Used as a safety input
Use this mode to connect to a safety device with a semiconductor output, such as a light curtain.
Used as a standard input
Use this mode to connect to a standard (non-safety) device.
