Can photocell enclosures be opened after locking? Learn about their design, risks, disassembly steps, and precautions to maintain performance and durability.
Introduction
Photocells, also known by the name of photoelectric sensors, are the main component of automated lightning systems. Their ability to automate the lightening control system in response to the level of ambient light helps in energy conservation and convenience.
It is because of the convenience and power saving capabilities of photocells that these are used in a range of lightening systems including street lights, commercial buildings for energy efficiency, parking lots, workplaces, homes, and garages.
However, when it comes to installation, longevity, troubleshooting and efficient operation of photocells, one of the most asked questions is ‘can the photocell enclosure and base be opened after being locked?’
This question is of significant importance when it comes to proper installation, ensuring optimal functionality, and troubleshooting the issues. In this article, we will answer this question in detail and have a thorough look at the implications of opening a photocell enclosure and its base once locked along with the steps to do so.
The Purpose of the Photocell Enclosure and Base Design
Let’s first have a look at what are the main functions of enclosure and base and why are they locked.
Protection Function
The first and foremost function of an enclosure and base is to safeguard the sensitive electronic components of a photocell. They provide a shield against dust and debris and protect against moisture that can negatively impact the functionality of photocell and result in rapid rusting. Moreover, the enclosure and base protect photocell components against exposure to UV light which is particularly important in outdoor settings.
The enclosure and base lock work as a waterproof and dustproof structure, protecting the structural and functional integrity of the photocell against extreme environmental factors.
Stability and Security
When the sensitive core components are protected against any unwanted interference from external factors, it helps ensure the stable and secure functioning of the photocells, thus ensuring optimized performance.
Can the Photocell Enclosure and Base Be Opened After Being Locked?
Let’s now answer the question in detail, whether you can open the locked enclosure and base of a photocell:
Designs that are Not Easily Opened
- Although, in some cases, you can open the enclosure and base once locked, most of the manufacturers make their photocells in a way that the design does not allow easy opening.
- Many photocell enclosures and bases use sealed structures with locking mechanisms like screws, clips, or gaskets, and once locked, they provide effective protection for waterproofing, dustproofing, and UV resistance. Hence it is neither easily possible, nor recommended to harm this seal by attempting to open the enclosure and base.
- In outdoor or harsh environments, attempting to open the enclosure could compromise the seal, affecting the device’s proper operation as it gives way to dirt, moisture and UV exposure.
Risks of Disassembly
Trying to disassemble the base and enclosure can pose several risks to the photocell:
- Forcibly opening the photocell enclosure can damage the seal, affecting its waterproofing and dustproofing capabilities, thus compromising its structural and functional integrity.
- Internal components like the circuit board and sensors could be damaged due to impact or electrostatic discharge during disassembly.
- Unauthorized disassembly might void the warranty, and the manufacturer may no longer offer repair services for damaged equipment.
Risks and Precautions During Disassembly:
Even for the designs that allow disassembly when needed, it should not be done until absolutely unavoidable. This is because once the seal is forcibly opened, there is no guarantee that it can be fixed back as effectively as it was before opening. This can result in long term inability to guard effectively against environmental factors.
Disassembly Steps and Methods:
If disassembly is unavoidable due to troubleshooting, inspection, or other reasons, here is a guide on how you can perform it securely:
- Ensure Power is Off: before starting the process of disassembly, make sure the power supply is disconnected to avoid hazards. Moreover, make sure, there is no residual current either.
- Use Proper Tools: Use specialized tools for safe operation, for example plastic prying tools and precision screwdrivers for disassembly. Avoid using overly forceful tools, as this could damage the clips or gaskets.
- Inspect the Design Locking Points: thoroughly inspect the locking system to see the location of screws, clips, and gaskets, etc and understand the design to make sure you can follow the correct sequence in disassembly.
- Gentle Disassembly: do not use excessive force during disassembly. If the seals are a bot too tight to be disassembled merely by using tools, try softening the seal with warm water or solvents. This helps loosen the rubber or silicon gaskets and ensures safe, damage-free and easy disassembly.
- Avoid Interfering with Internal Components: once the enclosure is open, do not touch the internet electronic components with bare hands. Use anti-static tools and gloves to avoid the risk of electrostatic discharge.
Factors Affecting the Disassembly of the Photocell Enclosure
There are several factors that decide whether or not an enclosure should be disassembled, and how would the performance be affected after disassembling the enclosure.
Design and Sealing
- Some photocell enclosures are single-use enclosures and are permanently sealed. For example those with welding or with strong adhesives. Opening such enclosures can compromise the performance and IP rating.
- There are other designs that can be disassembled. For example, those that are closed using screws and clips. However, disassembling them repeatedly can affect the seal performance. For example, rubber gaskets may loosen and clips may break or loosen causing the seal to be unable to prevent dust and moisture from entering.
Environmental Considerations
Some specific environmental conditions necessitate periodic inspection to ensure optimal performance. For example:
- Photocells installed outdoor in polluted areas may require thorough cleaning from time to time to make sure they keep performing to their best and that clogging may not occur.
- Environments with high humidity also call for periodic opening and cleaning of the enclosures to avoid rapid corrosion and short circuits.
- Industrial settings and those with high salinity, like coastal regions require users to inspect the photocells once in a while and clean them to make sure they keep working to their best.
Precautions When Disassembling the Photocell Enclosure
Disassembling a photocell enclosure can pose risks when done wrong and when precautionary measures are not taken. Make sure you take care of all the required safety measures before and during disassembly to avoid hazards and damage to the components. Always switch off the power before handling the photocell enclosure and use the appropriate tools for ensuring secure operation.
It is always advisable to seek a professional’s help especially when you don’t have experience of handling electronic components. Seeking help from an electrician reduces the chances of damages and hazards as they are trained to take precautionary measures and have specified tools to reduce the risk of damage.
When Not to Open the Photocell Enclosure and Base
Advantages of Sealed Design
In most cases, keeping the enclosure and base seal intact is highly advisable. Frequent and forceful disassembly can harm the components and affect the ability of the enclosure to protect them against dust, moisture, and UV exposure. Hence, it should not be opened under normal circumstances, until absolutely necessary.
Risk of Affecting Product Performance
Frequent disassembly can impact the waterproofing and dustproofing capabilities of the the enclosure. It can loosen the seal by deshaping the rubber or silicon gasket or break and loosen the locking clips. This will impact the safety and performance of components inside.
Conclusion
The question of whether a photocell enclosure and base can be opened after being locked highlights a critical aspect of installation, maintenance, and overall functionality. While some designs allow for disassembly, the risks of compromising the seal, damaging internal components, and affecting performance must be carefully considered. In most cases, the sealed design is essential for protecting sensitive components from environmental factors like dust, moisture, and UV exposure. Disassembly should only be attempted when absolutely necessary and with proper precautions. By understanding the design and function of photocells, users can make informed decisions to ensure their longevity and optimal performance.
