Product Description of DPP-EH/GS, a commonly used two-stage deviation switch for conveyors

Product Overview:The DPP-EH/GS two-stage deviation switch is a high-performance detection device designed specifically for conveyor systems. This switch has a two-level alarm function, which can accurately detect the deviation of the conveyor belt and provide reliable alarm and control signals, suitable for belt conveyor systems in various industrial environments.

Main features:

1. Two level alarm functionProvide two-level alarm signals based on the degree of deviation:

   • First level alarmWhen the conveyor belt deviates slightly, the switch emits a first level alarm signal, usually used to initiate preliminary corrective measures or alert operators.
   • Second level alarmWhen the conveyor belt deviates more severely, the switch emits a second level alarm signal, usually used to start the shutdown or strong correction device.

2. High sensitivity detectionDPP-EH/GS is equipped with highly sensitive sensors that can accurately detect the offset of the conveyor belt at different operating speeds and loads.

3. durableMade of durable materials and designed for use in high dust, high humidity, and other harsh environments.

4. Easy to installReasonable design, supports flexible installation, and can adjust different conveyor models and configurations.

5. Protection levelHaving a good level of protection ensures reliable operation of equipment in industrial environments.

Technical parameters:

• working voltage：AC 220V / 380V
• Working current：5A
• Contact configurationDual contact design
• Detection angleAdjustable, usually 15 ° (first level) and 30 ° (second level)
• working temperature: -20 ° C to+60 ° C
• Protection level：IP65
• Explosion proof gradeExplosion proof type can be selected

working principle:The DPP-EH/GS two-stage deviation switch uses its sensitive sensors to detect the deviation of the conveyor belt. When the conveyor belt deviates beyond the preset angle range, the switch will issue the following alarm signals based on the degree of deviation:

• First level alarmWhen the offset angle reaches 15 °, the first level contact of the switch will activate, issuing an alarm signal to prompt the operator or initiate preliminary corrective measures.
• Second level alarmWhen the offset angle reaches 30 °, the second level contact of the switch will activate, emitting a stronger alarm signal, usually activating the shutdown or strong correction device.

Installation and Debugging:

1. Installation locationInstall the DPP-EH/GS deviation switch on both sides of the conveyor bracket to ensure that the sensor can accurately detect the deviation of the conveyor belt. The installation position should avoid strong vibrations and external forces.
2. connectionFollow the wiring diagram in the product manual to ensure that the power supply voltage is correct and the wiring is secure.
3. debuggingAfter installation, proceed with debugging. Simulate the deviation of the conveyor belt, check whether the switch can emit the first and second level alarm signals at the correct deviation angle, and adjust the detection angle as needed.

Maintenance and upkeep:

1. Regular inspectionCheck the operation of the switch once a month to ensure its normal functioning.
2. Cleaning and maintenanceRegularly clean the sensor and housing of the switch, remove dust and foreign objects, and prevent affecting the detection accuracy.
3. functional testingConduct functional testing every quarter to ensure that the switch can accurately emit alarm signals.

Safety precautions:

1. Electrical safetyDuring installation and maintenance, be sure to disconnect the power supply to avoid the risk of electric shock.
2. Environmental requirementsAvoid using switches in extreme environments, such as high temperature, high humidity, or highly corrosive environments, and choose the appropriate protection level version.

Troubleshooting:

1. The switch has no responseCheck if the power supply is normal and confirm that the wiring is correct.
2. Decreased sensitivityClean the sensor and check if there are any foreign objects affecting the detection.
3. Alarm exceptionCheck the relay and control system to ensure there is no damage.

Related Q&A FAQs:

1. How to adjust the detection angle of the DPP-EH/GS two-stage deviation switch?

Adjusting the detection angle of the DPP-EH/GS two-stage deviation switch usually requires following the guidance in the product manual. The steps are as follows:

Positioning adjustment device: Find the angle adjustment screw or knob on the switch, which is usually located on the side or front of the switch.
Adjust angle: Use a suitable tool (such as a screwdriver) to slightly rotate the adjustment device and set the desired detection angle. According to the actual operation of the conveyor belt, set the offset angle for the first level alarm (e.g. 15 °) and the offset angle for the second level alarm (e.g. 30 °).
Test confirmation: After installation and adjustment, conduct a simulation test to ensure that the switch can accurately trigger the corresponding alarm signal when it detects an offset.

2. How to deal with problems in high dust or humid environments with DPP-EH/GS deviation switch?

When using the DPP-EH/GS deviation switch in high dust or humid environments, the following measures can be taken to ensure its normal operation:

Choose a switch with appropriate protection level: Ensure that the selected switch has sufficient protection level (such as IP65 or higher) to resist the intrusion of dust and moisture.
Regular cleaning: Regularly clean the casing and sensors of the switch to remove accumulated dust and dirt, in order to prevent affecting detection accuracy. Use appropriate cleaning tools and methods to avoid damaging the switch.
Check sealing: Regularly check the sealing of the switch to ensure that all seals and protective covers are in good condition to prevent moisture or dust from entering the interior.
Installation location selection: Choose an appropriate installation location to avoid direct exposure to extreme humidity or high dust environments. If necessary, a protective cover or dust cover can be installed.
