Functional Description
5437-687 is a NetCon 24 Channel FTM developed by Woodward. Field Termination Modules (FTMs) serve as pivotal components in establishing a seamless connection between field wiring and the front of MicroNet control's I/O Modules. These modules play a crucial role in streamlining the integration of various components within the control system, offering a range of benefits that enhance both convenience and operational efficiency. The fundamental purpose of FTMs is to provide a reliable interface through which field wiring can be linked to the subminiature D-type connectors positioned on the front of the I/O Modules. This direct linkage ensures efficient data transmission and communication between the field devices and the control system, facilitating the exchange of critical information for accurate monitoring and control.
Features
- One of the features of FTMs is the provision of cage-clamp terminal connection points. These connection points offer a secure and efficient means of attaching field wiring to the I/O Modules. The cage-clamp design ensures a dependable connection that remains stable even in challenging environmental conditions, reducing the likelihood of signal loss, interference, or disruptions.
- FTMs play a role in providing shield termination and electromagnetic interference (EMI) protection. Shielding is crucial in minimizing the impact of external electromagnetic disturbances on the integrity of signals within the system. By integrating EMI protection, FTMs contribute to maintaining signal quality, which is paramount in ensuring accurate and reliable data exchange.
- Another notable advantage of FTMs is their compatibility with 35 mm DIN Rails. This design feature allows for easy and standardized mounting, enhancing the organization and structure of the control system's components. The DIN Rail mounting capability simplifies installation and maintenance processes, facilitating quick access for adjustments or replacements when necessary.
- It offer a distinct advantage by eliminating the need for interposing terminal blocks commonly used for field wiring. By removing this intermediary step, FTMs streamline the connection process, reducing complexity and potential points of failure. This not only enhances the overall efficiency of the system but also contributes to the reduction of maintenance requirements and the optimization of space within the control panel.
High voltage FTM
- When dealing with HIGH VOLTAGE applications, particularly when utilizing the high voltage Field Termination Module, it's crucial to exercise extreme caution and adhere to safety protocols to ensure the well-being of personnel and the integrity of the equipment. This is particularly relevant when there is a presence of 125 Vdc on the FTM terminal blocks.
- It's important to note that the voltage potential on the FTM terminal blocks directly translates to the sub D connectors and the cable when connected to the FTM. In the context of the high voltage FTM, this means that if there is a voltage reading of 125 Vdc on the terminal blocks, the same voltage level will be present on the FTM sub D connectors and the cable when they are interconnected.
- Given the potential risk associated with high voltage, it is absolutely imperative that any power present on the FTM terminal blocks is completely removed prior to the installation of the Analog I/O module or the FTM itself. This precautionary measure is a fundamental safety step designed to prevent accidental electrical shocks, equipment damage, or even more serious consequences.
Fuse replacement
- Verify the Correction of the Issue: Before proceeding with any maintenance, safety is paramount. It's crucial to identify and address the root cause that led to the fuse blowing in the first place. Investigate the system and identify any faulty components, electrical overloads, or irregularities that could have caused the issue. Correcting this underlying problem is essential to prevent the fuse from blowing again in the future.
- Carefully Remove the FTM Cover: Ensuring safety and precision, begin by removing the cover of the Field Terminal Module (FTM). This step requires caution to prevent accidental contact with the delicate circuitry within the module. Gently follow the manufacturer's guidelines for this specific model. Usually, the process involves carefully pinching or releasing a retaining mechanism (like a barb) that secures the cover, followed by lifting the cover away from the module.
- Locate and Replace the Fuse:With the cover removed, the blown fuse becomes accessible. Identify the exact location of the blown fuse on the FTM. Use the appropriate tools, such as pliers or fuse pullers, to carefully extract the blown fuse. Take note of the fuse's size, type, and rating, as it's critical to replace it with an identical fuse to maintain the safety and proper functioning of the system. Insert the new fuse into the same slot, ensuring it's snugly seated.
- Reassemble and Replace the FTM Cover: Once the new fuse is securely in place, it's time to reassemble the FTM. Begin by properly aligning the cover over the module's housing. Be mindful of any wiring or components that might interfere with the cover's placement. Following the manufacturer's instructions, gently press or slide the cover into position until it's securely seated. Verify that any retaining mechanisms, like the barb, engage properly to hold the cover in place.
