PRODUCT INTRODUCTION

In order to ensure the normal and reliable operation of the instrument, the probe and controller must be installed correctly according to the relevant drawings and actual needs. When the user disassembles the level controller, it is strictly prohibited to apply force to the housing to rotate the probe. Use a wrench to turn it.

a) Common installation methods

1. When installing horizontally, the length of the probe cover G must extend into the wall of the container and tilt it horizontally downward by about 5°.

2. When installing vertically, the distance from the wall should be greater than 200mm, and the total length of the probe S must be greater than or equal to the position of the control point.

3. The distance between the high and low level probes should be greater than 500mm.

4. When using for outdoor installation, a protective cover should be added.

5. Ensure that the instrument case is reliably grounded. A separate ground wire is recommended.

6. Pay attention to the installation space above.

b) Probe installation technical requirements

Installation can generally be determined according to the user's drawing process requirements and actual working conditions, but the following principles should be followed:

1. Installed in an easy-to-access or maintenance location with the shortest connection line and the most convenient wiring.

2. The distance between the front end of the probe and the opposite wall is less than 300mm;

3. Avoid direct sunlight and rain;

4. The spacing between the upper and lower material levels should be greater than 1000mm;

5. The distance from the ash support should be greater than 300mm;

6. The length of the probe deep into the inner wall of the hopper is not less than 450mm, and the lead hole of the electrical box is downward;

7. Separately install the installation pipe horizontally at an angle of 15° (10°-15°) and weld it to the ash wall to ensure air tightness. (When soldering, the probe and the mounting tube must be separated to avoid high temperature melting of the probe wire during soldering;

8. Avoid strong magnetic fields to avoid interference and damage;9. Avoid the blanking hole to avoid the material directly scouring the probe and causing false alarms.

INSPECTION AND NORMAL WORKING CONDITIONS

a) Inspection products are provided with on-site indication function, when inspecting

1. Unscrew the level controller cover, lie on the table, and the probe is hanging out of the table;

2. Connect the power supply correctly, the LCD shows 000;

3. Hold the probe with your hand. After 3 seconds, the relay is closed and the red light is on. When the hand is released, the relay is released after 3 seconds, and the red light is off. If the working mode is set to A01, the opposite is true;

4. The level switch function is normal and can be installed on site.

b) normal working condition

The working state of the system when it is not alarming: the red alarm indicator is off;

The working state of the system when it is alarmed: the red alarm indicator is on.

CALIBRATING & SPECIAL NOTE & RESTORE FACTORY DEFAULTS & TROUBLESHOOTING

这里可以自定义设置

Calibrating:

Click ▽ to display “d20”, then press △▽ to change the value; (Note: you must first click △ and then debug according to the working conditions); after changing, press SET to save and jump to The next menu item “C00” changes the value as the previous step; after changing, press the SET button to save and skip to the next menu item “b00”, and change the value as the previous step;

After changing, press the SET button to save and adjust to the next menu item “A00” to change the value as in the previous step. After the change, click SET until the screen displays the measurement interface “0000”.

Code

Desc.

Default

A00

A00 for NO A01 for NC

No

B00

B represents the sensitivity (00-09), the higher the value, the higher the sensitivity;

B03

C00

C means the delay (00-60), the larger the value, the longer the delay time;

C00

D00

D represents the value of the capacitor (00-99). The relay switches when the material meets or exceeds the set capacitance when it touches the sensor probe.

Special note:

This product has been dynamically simulated and debugged at the time of shipment. Generally, it is not necessary to re-calibrate when the material in the silo changes. However, if there is material in the case of use, but there is no alarm or no material but alarm, please follow the operation again to calibration:

Operation instructions

Note: 1. material must be empty when calibrating (or the material is more than 500mm away from the probe)
2. calibration can eliminate the zero drift caused by various factors, such as cable length, container wall size and other factors.

Troubleshooting:

1. power failure:

After checking whether the power supply and its wiring are normal, the following troubleshooting can be performed and checked and repaired:

Fault phenomenon

Reason

method

The display does not light.

Power disconnect/short circuit/instrument component damage

Check power/send factory repair

Instrument alarm, control room is not alarmed

Relay damage / signal line connection error

Check relay output / rewiring

2. probe failure:

First check whether the installation of the probe meets the installation technical requirements before performing the following troubleshooting and maintenance:

Fault phenomenon

Reason

Method

The material does not touch the probe and the alarm light is on.

High sensitivity

Reduce sensitivity / readjust

Too close to the wall of the installation barrel

Check the barrel wall

Probe short circuit / protective sleeve break

Factory maintenance

Electronic component damage

Factory maintenance

The material has touched the probe and the alarm light is off.

Sensitivity is too low

Properly improve sensitivity / re-calibrate

Poor grounding

Check ground

Probe open circuit

Factory maintenance

Electronic component damage

Factory maintenance

Flashing red light

Sensitivity is critical

Properly increase/decrease sensitivity / re-calibrate

Poor connection of probe or protective sleeve

Check probe or protective sleeve wiring

Measured in liquid, stirred tank, interface

Appropriate increase in delay time
