TOPWORX Feedback Switch Installation and Use Guide

1、 Preparation before installation of TOPWORX feedback switch DXP-EH0GN4S
Confirm the model and specifications
Select the appropriate model based on the application scenario (such as TXP-T2CGNPM, TXP-L2CGNPM, etc.), verify electrical parameters (such as operating voltage, current capacity), protection level (such as IP67), and explosion-proof certification (such as Ex d II C T4) to ensure compatibility with the control system.
Check the installation environment
Avoid environments with high temperatures, humidity, corrosive media, or explosive gases.
Ensure that the installation location is free from strong vibrations or mechanical impacts to prevent accidental triggering.
Prepare tools and accessories
Supporting installation brackets (such as AV-TA11, AV-TA13).
Explosion proof cable joints, sealing rings (if waterproof and dustproof are required).
Basic tools such as screwdrivers and wrenches.

2、 TOPWORX Feedback Switch DXP-EH0GN4S Installation Steps
Fixed installation bracket
TOPWORX feedback switch DXP-EH0GN4S uses a bracket (such as AV-TA11) to secure the switch to the valve actuator or pipeline, ensuring that the bracket has a flat contact surface with the equipment and avoiding tilting or loosening.
Example: TXP-L2CGNPM can be directly installed on ISO/NAMUR actuators through NAMUR standard brackets without the need for additional accessories.
Connect the valve drive shaft
Align the sensing part of the switch (such as the cam or striker) with the valve drive shaft or cam, adjust the position so that the switch can be accurately triggered when the valve is opened/closed in place.
Attention: Avoid excessive axial load to prevent damage to internal components of the switch.
electrical wiring
Power cord: Connect to the power terminal of the control system, ensuring correct polarity (if it is a DC power supply).
Signal line: Connect the switch output signal line to the control system input module (such as PLC).
Grounding wire: If the equipment requires grounding, it must be reliably connected to enhance anti-interference ability.
Sealing treatment: If used in humid or corrosive environments, the wiring port should be sealed with a sealing ring or explosion-proof cable joint.
Adjustment and Testing
Action point calibration: Manually operate the valve to the fully open/fully closed position, observe the switch indicator light or control system signal, and confirm that the trigger point is accurate.
Fine tuning: If a position deviation is triggered, it can be corrected by rotating the cam or adjusting the position of the firing pin.
Repetitive testing: Operate the valve multiple times to verify the stability of the switch signal, ensuring no shaking or false alarms.

3、 TOPWORX Feedback Switch DXP-EH0GN4S Precautions for Use
TOPWORX feedback switch DXP-EH0GN4S regular inspection
Appearance: Check if the casing is damaged and if the wiring is loose.
Performance: By monitoring the switch signal through the control system, confirm that the triggering sensitivity has not decreased.
Environment: Clean the dust or debris around the switch to prevent clogging of the sensing window.
Maintenance and replacement
If the internal components of the switch are damaged (such as micro switch failure), it is necessary to replace them with spare parts of the same model (such as spare part number 11-11524-A2).
Disconnect the power supply during replacement to avoid the risk of short circuit.
TOPWORX Feedback Switch DXP-EH0GN4S Safety Specification
Before operating in explosive environments, confirm that the explosion-proof rating of the switch meets the regional requirements (such as ATEX, IECEx certification).

It is prohibited to plug and unplug wires with electricity to prevent danger caused by electric arcs.
4、 TOPWORX Feedback Switch DXP-EH0GN4S Common Problem Solution
The switch does not trigger
Check if the valve has reached the preset position and adjust the cam or striker position.
Confirm that the power supply is normal and the wiring is not loose or short circuited.
Signal unstable
Check if the wiring is disturbed (such as near power cables), rewire or add shielding layers.
Clean the sensing window and eliminate the influence of dust or oil stains.
Water ingress into the shell
Check if the sealing ring is aging and replace damaged seals.
Ensure that the conduit system is well sealed to prevent water from seeping into the cables.

5、 TOPWORX Feedback Switch DXP-EH0GN4S Application Scenario Example
Petrochemical industry: TXP-E2CGNMM0000N is used for high-temperature and high-pressure pipeline valves, providing real-time feedback on the on/off status to ensure safety interlocking.
Water treatment system: TXP-M2CGNPM monitors the position of the outlet valve of the water pump to prevent equipment damage caused by water hammer effect.
In the power industry, TXP-T2CGNPM is installed on steam valves and works in conjunction with control systems to achieve automatic regulation and improve operational efficiency.
