To check the power wiring

To ensure the proper functioning and safety of the power wiring, the following steps should be taken:

  • Verify Wiring Alignment: Check that all incoming power wiring aligns with the provided basic drawings. This helps ensure that the wiring is correctly connected and matches the intended configuration.
  • Follow Approved Wiring Practices: Adhere to approved wiring practices as described in the previous chapter. These practices ensure that the wiring is installed correctly, minimizing the risk of electrical faults or hazards.
  • Check Terminal Connections: Inspect the tightness of all electrical terminal connections. Loose connections can lead to poor electrical conductivity and potentially cause overheating or intermittent power supply. Ensure that all connections are securely tightened.
  • Inspect for Damage: Carefully inspect the wiring for any signs of damage or fraying that may have occurred during the installation process. If damaged or frayed wires are found, they should be replaced to maintain the integrity of the power wiring system.
  • Verify Voltage and Frequency: Check the incoming power supply voltage and frequency to ensure they match the specified requirements (e.g., 125 V dc, 115 V ac, 230 V ac). Additionally, verify that the power supply is clean and free from electrical noise that could adversely affect system operation.
  • Verify Jumper Positions: If using ac to dc converters, ensure that the JTX1 or JTX2 jumper positions on the front of the converter are set correctly according to the voltage (115 V ac or 230 V ac) being supplied.
  • Grounding Test: Conduct tests to ensure proper grounding of the 125 V dc system. A qualified person should perform these tests following appropriate safety procedures. Using a 2000-ohm, 10 W resistor in series with a dc ammeter, measure the current from the P125 V dc and N125 V dc terminals. The measured current should fall within the range of 1.7 to 2.0 mA. If the measured current exceeds 2.0 mA, it indicates the presence of additional grounds that need to be removed from the system.
  • Identify Grounding Issues: Test currents of approximately 65 mA usually indicate the presence of one or more hard grounds in the system. Currents in multiples of 1 mA typically suggest the presence of multiple BJS jumpers, which should be addressed accordingly.

Startup Checks

After the installation of the Mark VI control panels, it is essential to perform startup checks to ensure the equipment is operating correctly and safely. Although the panels undergo pre-cabling and factory testing before shipment, final checks should be conducted to address any potential issues that may have arisen during installation. These checks are important as the equipment carries the risk of electrical shock or burns. Here are the steps to follow during startup checks:

  • Ensure Power is Turned Off: Before handling or connecting any conductors to the equipment, take appropriate safety precautions and ensure that all power sources are switched off. This step is crucial for personal safety and prevents electrical hazards during the startup checks.
  • Inspect Control Panel Components: Examine the control panel components for any signs of damage that may have occurred during shipping or installation. Look for physical damage such as dents, scratches, or broken parts. If any damage is detected, it should be reported to GE Product Service for further evaluation and resolution.
  • Check for Loose Cables or Wires: Inspect all cables and wires within the control panel for proper connections. Ensure that all connections are secure and there are no loose or disconnected cables. Loose connections can cause malfunctions or safety hazards, so it is important to address any loose cables or wires promptly.
  • Examine Components and Retainer Clips: Check the various components of the control panel, such as relays or retainer clips, for proper positioning and functionality. Ensure that all components are securely fastened and functioning as intended. If any components are loose or damaged, they should be repaired or replaced before operating the equipment.
  • Report Shipping Damage: If any damage is discovered during the inspection that can be attributed to shipping, it should be promptly reported to GE Product Service. Providing them with accurate details of the damage will assist in resolving any issues and ensuring the equipment's optimal performance.

By following these startup checks, you can verify the integrity of the Mark VI control panels, address any potential issues, and ensure the equipment is ready for safe and reliable operation. It is always important to prioritize safety and report any concerns or damage to the appropriate authorities or service providers for proper resolution.

System Features

The system features of the Mark VIe controller or pack involve the handling of data communication and the convergence of internal data values in a dual control system.

  • Preferred Network Selection: During power-up, the Mark VIe controller or pack listens for data on both networks. The channel that sends the first valid packet is designated as the preferred network. This designation ensures that the pack or controller uses the data arriving on the preferred channel as long as it remains valid.
  • Failover Mechanism: In the event that the preferred channel fails to deliver the data within a frame, the other channel takes over as long as it provides valid data. This failover mechanism prevents a specific I/O pack or controller from constantly switching between two data sources, which could result in instability or unreliable operation.
  • Different Preferred Data Sources: Different I/O packs or controllers within the system may have different preferred data sources. This can occur based on the specific configuration or failure conditions of the system. Each pack or controller determines its preferred data source based on the first valid packet received during power-up.
  • Convergence of Internal Data: In a dual control system, the application software running on each controller attempts to produce the same results. However, due to factors such as mathematical round-off and differences in past history (such as power-up times), internal data values may differ between controllers after many iterations of the application software.
  • Data Convergence Process: To converge the internal data values between controllers, a designated controller's internal data (state) variables are taken and transmitted to the non-designated controller. This allows the non-designated controller to utilize the same internal data values as the designated controller, ensuring consistency and synchronized operation between the controllers.
