1. Always keep safe distance between the high voltage part and the instrument, probe and operator.
2. Measurements must not be taken when thunderstorms are nearby.
3. Do not operate the instrument or accessories in explosive atmospheres.
4. After the battery alarm of the instrument, please turn off the power to charge.
5. Do not open the instrument without permission, this will affect the warranty of the product. The factory is not responsible for self-disassembly.
6. When the instrument is transported, it should avoid rain erosion and prevent collision and falling.
7. When storing and keeping the instrument, attention should be paid to the ambient temperature and humidity, and it should be protected from dust, moisture, shock, acid, and corrosive gas.

SUMMARIZE

The intelligent dehumidification device adopts the semiconductor refrigeration dehumidification
method, actively sucks the humid air in the confined space into the dehumidification duct under the action of the fan, and the water vapor in the air is condensed into water after passing through the semiconductor refrigeration mechanism, and then discharged out of the cabinet through the water pipe Body, can achieve a good dehumidification effect.

By reducing the water content in the air, the relative humidity and absolute humidity are reduced at the same time, the temperature is hardly raised, and there will be no negative impact caused by the temperature difference, which fundamentally eliminates or reduces the occurrence of accidents, and will not accelerate the cabinet due to high temperature. Aging of internal components and cabinets. Effectively prevent safety hazards such as aging of equipment in the cabinet, reduction of insulation strength, breakdown of secondary terminals, mildew of materials and corrosion of steel structural parts, and ensure the safe operation of the power grid.

• Mechanical control cabinet, box type substation

PRINCIPLE INTRODUCTION

The intelligent dehumidification device is composed of a power supply system, an air supply system, a semiconductor refrigerator, a temperature and humidity detection control circuit, a heating circuit, a wireless module and a drainage pipeline.

1. Dehumidification principle

After the humid air is sucked by the fan, it flows through the specially designed air duct, and first passes through the semiconductor refrigerator to cool down and condense. After fully dehumidifying within the set starting threshold, the air humidity in the cabinet is reduced to below the dew point, and the entire moisture-proof condensation heating process is completed.

At the same time, the signal acquisition sensor of the intelligent dehumidification device is external, which can accurately collect the real humidity in the cabinet in real time, so as to ensure that the intelligent dehumidification device starts dehumidification in advance when the condensation condition is about to be reached in the cabinet.

2. Heating function(optional)

When the temperature of the box is lower than the set start threshold, Default 5°C, the dehumidification device starts the internal heater circuit (the heater is connected externally, and the power can be connected to 100-300W), until the temperature of the box rises to the set start threshold, the heater circuit stops working.

3. RS485 communication function(optional)

When the dehumidification device with RS485 communication function receives the data from the host computer, it will reply the data to the host computer immediately after analyzing the data. One host computer can connect up to 200 units (the host computer recommends connecting a 120 ohm load between A and B) Resistance, adjustable communication address; remote control, adjustment of operating parameters and fault reporting function).

4. Wireless remote control function(optional)

When the dehumidification device with wireless control function receives the data from the main control room, it will reply the data to the main control room immediately after analyzing the data, and the wireless communication can reach 2000 meters. (Remote control, adjustment of operating parameters and fault reporting function)

Note:
Alarm node: default dry node, equipment failure: default normally open.

TECHNICAL SPECIFICATION

INSTALLATION AND START-UP

4.1 – Wall-mounted installation dimension (unit: mm)

Notes:

1. Fix with M5 screws or 5mm rivets. When installing, the dehumidifier must be placed vertically with the water outlet facing down.
2. Ensure that there is more than 5cm of space between the front of the dehumidifier and other devices to ensure the air from the front fan outlet.
3. One end of the outlet pipe is connected to the drain of the dehumidification device, fixed with a clamp to keep the water pipe smooth and not entangled, and the other end leads to the outside of the box.
4. Connect the power terminal L/N to AC220V power supply.

4.2.- Connection terminal (see label on the Side part)

OPERATION MODE

5.1.- Key description

5.2.- Manual/ Auto mode switch

The device default in the Automatic state and the “Auto” indicator light is on. After pressing the ”
“key, the “Auto” indicator light is off, and the “Manual” indicator light is on. At this time, the dehumidifier module starts work.
Again pressing the” ” key, the dehumidifier automatically turns to Auto Mode.
Press multiple times the” ” key to cycle through the Auto/Manual mode.

5.3.- Parameter setting procedure

After the power is turned on, the device enters the self-test program, and enters the Auto mode. the screen displays the current temperature and humidity values.

Press the “ ” to can set the P1-P7 parameter values (Dehumidification start threshold,
Dehumidification stop threshold, Heater start threshold, Temperature HYS, Defrost start
threshold ,Working mode ,Modbus address)
Press the “ “the lower row numbers will flash, Then press the ,, ,, or,, ,, to
select and modify the P1-P7 parameter value;
After the modification completed, press the” ” to save, the number stops flashing.
