How to Modify the Wiring Check Parameter of a Discrete TBX Module

At a Glance

This function is used to permanently check the quality of the link between:

Sensors and inputs,
Actuators and outputs.

The input wiring check function is used to permanently check the quality of the link between the sensors and the inputs of the module. This function is used to detect the two main faults on a input module:

Loosening of screws on the terminal block,
Short-circuit at the grounding of the cabling wires.

Modular Discrete TBX bases with input wiring check are fitted with 2 switches, which must be configured by the user in order to make inputs compatible with the 2-wire proximity sensors.

With all static outputs protected against short-circuits of the 0 V or 24 V load and against over-loads, the output wiring check function also performs a permanent open circuit detection function: This detection is performed both when the pre-actuator is at idle (OFF) and triggered (ON).

NOTE: This parameter can be modified in online mode.

Procedure

The following table presents the procedure for activating or deactivating the Wiring check parameter.

Step	Action
1	Access the hardware configuration screen of the required module.
2	Select the required channel group in the channel area.
3	In the configuration area, click the checkbox in the Wiring check column of the channel to be configured.
4	Repeat the operation for every channel to be configured (from step 3).
