Chassis NII_Z_3: Check EIFE Chassis Position Limit Switches

Safety Instructions

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462, NOM 029-STPS, or local equivalent. This equipment must only be installed and serviced by qualified electrical personnel. Unless specified otherwise in the maintenance procedures, all operations (inspection, test, and preventive maintenance) must be carried out with the device, the chassis, and the auxiliary circuits de-energized. Check that the device and the chassis are de-energized on the upstream and downstream terminals. Always use a properly rated voltage sensing device to confirm that the device, the chassis, and the auxiliary circuits are de-energized. Install safety barriers and display a danger sign. During the tests, it is strictly forbidden for anyone to touch the device, the chassis, or the conductors while voltage is applied. Before turning on power to this equipment, check that all connections are made with the correct tightening torque and the device is open (OFF position). Before turning on power to this equipment, put all devices, doors, and covers back in place. Before turning on power to this equipment, beware of potential hazards and carefully inspect the work area for tools and objects that may have been left inside the equipment. Failure to follow these instructions will result in death or serious injury.

Checking that the EIFE Interface Communicates Correctly

Step	Action	Corrective action
1	If the device is equipped with an MN undervoltage release, either connect it to the power supply with its rated voltage or remove the MN undervoltage release.
2	Connect a PC running EcoStruxure Power Commission software to one of the Ethernet communication ports on the EIFE interface by using a standard Ethernet cable.
3	Launch EcoStruxure Power Commission software.
4	Click Launch Device Discovery.
5	In the Discover Device(s) window, check that the IP address of the EIFE interface is indicated.	If the IP address of the EIFE interface does not display: Check that the LED of the ETH port connected to the PC is green and blinking. If the LED is not blinking green, check that the EIFE interface is powered and the link is connected. Check that the connection to the local network is activated on your PC. Click Launch Device Discovery again.
6	Click START DEEP SCAN. Result: The device that you want to communicate with appears in Devices List.
7	Select the device and click ADD TO PROJECT.
8	In the SWITCHBOARD VIEW window, click Connect to device (green button).
9	Click the Device Check up section. Result: The product switchboard displays.
10	In the Device tab, check that Device Status > Breaker racked position is Test position.	If the device position is not correctly displayed in EcoStruxure Power Commission software, follow the procedure to check manually the operation of the chassis position limit switches of the EIFE interface.
11	Rack in the device to the connected position.
12	Check that Device Status > Breaker racked position is Connected position.
13	Rack out the device to the disconnected position. Result: A message is displayed: Error: Device is disconnected.
14	Click OK to acknowledge the message.
15	Click the Maintenance tab.
16	Rack in the device to the test position.
17	In Cradle Position Counters check that Breaker rack test counter increments.	If the counters do not increment correctly in EcoStruxure Power Commission software, replace the EIFE interface and do the procedure again.
18	Rack in the device to the connected position.
19	In Cradle Position Counters check that Breaker racked-in counter increments and in Last Operation Dates check that the date and time are correct.	If the counters do not increment correctly in EcoStruxure Power Commission software, replace the EIFE interface and do the procedure again.

Manually Checking Operation of EIFE Chassis Position Limit Switches

If the chassis position is not correctly indicated in EcoStruxure Power Commission software, check the operation of the chassis position limit switches manually, by following the three stages described below:

Stage	Description
1	Remove the EIFE interface.
2	Check the limit switches by operating them manually.
3	Reinstall the EIFE interface.

Follow this procedure to remove the EIFE interface:

Step	Action
1	Remove the auxiliary terminal shield.
2	Remove the Ethernet cable (A) from the EIFE interface. A Ethernet connection B ULP cord connection
3	Disconnect the ULP port module cord from the ULP port module and the EIFE interface (B).
4	Remove the terminal block identification plate.
5	Remove the EIFE interface by using a thin screwdriver inserted into the slot in the metal plate at the top of the EIFE interface, and releasing the clips holding the top of the EIFE interface in place.
6	Remove the screwdriver and press down on the EIFE interface to unclip the bottom clips and pull out the EIFE interface.
7	Reconnect the Ethernet cables to the EIFE interface to perform the test.

Follow this procedure to check the actuators and operation of the EIFE chassis position limit switches:

Step	Action	Corrective action
1	Check that the actuators move freely.	If the actuators do not operate correctly: For MasterPacT MTZ1 manipulate the actuators so that they are moving freely For MasterPacT MTZ2/MTZ3 put the actuators into the correct position. If the actuators are damaged, replace them.
2	Locate the three limit switches on the back of the EIFE interface.
3	When no limit switch is pressed, check that Breaker racked position in EcoStruxure Power Commission software is Disconnected.	If the device positions are not displayed correctly in EcoStruxure Power Commission software, replace the EIFE interface and do the procedure again. If the positions are displayed correctly in EcoStruxure Power Commission software, operate the actuators manually to check that they are not stuck. For MasterPacT MTZ1: If the problem persists, contact your Schneider Electric Services representative. For MasterPacT MTZ2/MTZ3: If the problem persists, change the actuators. Do the procedure again.
4	Press and hold the two outside limit switches.
5	Check that Breaker racked position in EcoStruxure Power Commission software changes to Test.
6	Press and hold the two limit switches on the right.
7	Check that Breaker racked position in EcoStruxure Power Commission software changes to Connected.
8	Exit EcoStruxure Power Commission software.

Follow this procedure to reinstall the EIFE interface:

Step	Action
1	Remove the Ethernet cables from the EIFE interface.
2	Reinstall the EIFE interface. Refer to Enerlin'X EIFE - Embedded Ethernet Interface for One MasterPacT MTZ Drawout Circuit Breaker - Instruction Sheet.
3	Reinstall the terminal block identification plate.
4	Reconnect the Ethernet cables and ULP cord to the EIFE interface.
5	Reconnect the ULP cord to the ULP port module.
6	Reinstall the auxiliary terminal shield.
7	Close the equipment door.
8	Continue the procedure to check the operation of the EIFE interface from step 15.
