Troubleshooting: Control Operations from IO Module

@writer: (confirmed 12/11/24) topic shared in Masterpact MTZ1 User Guide (DOCA0100), Masterpact MTZ2/3 User Guide (DOCA0101), and in the appendix in Masterpact MTZ End-user and Manufacturer Maintenance Procedures (DOCA0103 and DOCA0104). Any changes made will be made in all these guides.

Definition

Control operations include commands to open and close the device from the IO module with the Breaker Operation predefined application.

For information about control operations from the IO module, refer to DOCA0055•• Enerlin'X IO - Input/Output Application Module for One Circuit Breaker - User Guidein Related Documents at the beginning of this guide.

Device Cannot be Controlled from the IO Module

Problem description	Symptom	Probable causes	Solutions
Device cannot be opened or closed.	–	The IO module is not configured for Breaker Operation predefined application 2.	Configure the IO module for Breaker Operation predefined application 2, by using the rotary switch and pressing the Test/Reset button for 5 seconds to validate the configuration.
	–	The device control mode is set to Manual.	Change the control mode to Auto.
	Local open or close orders wired on digital inputs I5 or I6 do not control the device.	The device control mode is set to Remote.	Change the control mode to Local by using the control mode selector switch wired on the digital input I1 of the IO module (I1=0).
	Remote open or close orders wired on digital inputs I2 or I3 do not control the device.	The device control mode is set to Local.	Change the control mode to Remote by using the control mode selector switch wired on the digital input I1 of the IO module (I1=1).
Device cannot be closed.	–	The close command is inhibited by the IO module configured in the Breaker Operation predefined application 2.	Enable the close command by using the selector switch wired on the digital input I4 of the IO module (I4=1).
Device cannot be closed.	–	The close command is inhibited by a command from the communication network or EcoStruxure Power Commission software.	In EcoStruxure Power Commission software, in the Device Check-up > Devices menu, change the value of the Remote Close Breaker Inhibited parameter from Enabled by communication to Disabled.

Inhibit Closing by IO Module is Not Operational

Problem description	Probable cause	Solution
Device can be closed while selector switch wired on a digital input of the IO module is set to Inhibit (I4=0).	The MicroLogic X setting Breaker closing by digital input is disabled.	In EcoStruxure Power Commission software, in the General menu, in Breaker Closing Inhibition, change the value of the Allow control by a digital input parameter to Enable.

Additional Checks

If the troubleshooting actions described above do not work, the problem might be in the mechanical or electrical operations of the device. Refer to the troubleshooting information for Mechanical Control Operations and Electrical Control Operations.
