Instruction for installation and safety

Please read this instruction carefully before use.

This instruction is to prevent the risk of personal injury or death and property damage due to inappropriate use of the product and enable the user to use the product safely.

※ Warning : This indicates a risk that may cause serious injury or death to the user and must be observed.

Warning

Do not perform maintenance or inspection while power is applied. (It may cause electric shock.)

Please keep the foreign substances such as wire pieces, welding pieces, or metal pieces from the inside of the product. (It may cause fire, electric shock, or product failure. If it gets wet with water or liquid, stop using it immediately and wipe the wet area with a cotton swab or contact our customer center.)

Wiring work should be done by a professional electrician who is familiar with the wiring details. (There is a risk of electric shock or fire.)

Do not disassemble, repair, or modify the product arbitrarily except for the service engineer. (It may cause electric shock or product damage. If any abnormality on the product, please contact the customer center to take action.)

Do not use a load that exceeds the rated switching capacity of the relay contact part. (Be sure to use the rated value allowed by our company. It may cause malfunction.)

Do not install on the same panel as a high voltage device.

Keep a distance of 50mm or more between the wiring duct and surrounding modules.

In places where there is a high risk of life or property, be sure to install a two-tier safety device and use it on a non-combustible material such as metal.

※ Caution : This indicates that the user needs to be careful in handling if there is a possibility of minor injury or product damage.

Caution

Do not give a strong shock to the product. (It may cause damage to the product or failure.)

For installation, avoid places where high temperature, high humidity, and condensation are prone to, and places with dust, corrosive gas, explosive gas, combustible gas, or salt but install it in a well-ventilated room without direct sunlight. (It may shorten the life of the product and cause a malfunction.)

The wiring of the input/output line together with a high-voltage line or power line may cause induction interference, resulting in malfunction or failure.

Install the controller and other devices (relay, inverter, magnetic contactor) at a distance to avoid the effects of radiated noise and heat. (Use an insulation shielding transformer or noise filter to prevent noise penetration.)

This controller has countermeasures against noise, so it can be used without grounding unless there is a lot of noise.

※ However, please refer to the following for grounding.

- Ground separately from the ground wires of other equipment.

- It is recommended to use a dedicated ground. (Unless a dedicated grounding is available, please use common grounding.)

- For grounding work, use Class 3 grounding (Ground resistance 100Ω or less.)

- Comply with the equipment standard of each country.

Connect all cable connectors firmly to the terminals. (A loose connection may result in incorrect input or output.)

Screws on the terminal block must be tightly tightened, and the torque of 0.5~0.6N.m is recommended. (If the screws are not tightly tightened, it may cause a short circuit, fire, product failure, or malfunction.)

For RS485 communication,  485 dedicated communication lines are recommended. (General wires may cause noise or malfunction.)

It is recommended to use a shielded cable to connect a temperature sensor such as NTC or PT100. (Using general electric wire may cause malfunction so that the correct temperature value may not be displayed.)

※ This product must be disposed of under national regulations on industrial waste products.

General Safety Instruction

Please do not hit the product with a hard object or press it too hard. (The product may be damaged.)

Do not install the product in a location exceeding the permitted temperature. (The product may be damaged, or its life may be shortened.)

Please do not use it in a place with a large or rapid temperature change. (Dew may form inside the product, which may damage the product.)

Be careful not to let water, liquid, metal, or charged particles enter into the product. (Product damage or electric shock may result.)

Do not use or store in direct sunlight, dusty or dirty places.

Do not use or store in places with severe vibration.

Do not use or store it in a place where chemical substances or oxides are evaporated or contained in the air.

Do not wipe with paint thinner or solvent.

Do not store or operate the LCD in a place exposed to direct sunlight. The sun's ultraviolet rays may degrade the LCD quality.

Be sure to store the LCD monitor in a place within the permitted temperature range.

If the product is stored in a place where the temperature is lower than permitted, the LCD's liquid may condense and damage the LCD.

Storage of the product at a temperature above the permitted may cause the liquid to be isotropic and non-reducing.

Turn off the power of the product and wait for a few seconds to power it back on. If you power on too quickly, the product may not work normally.

▞Calculation of power consumption and humidification

In Korea, the most widely used industrial electricity is 380VAC (3Φ) and 220VAC (2Φ or 3Φ). When installing an electrode humidifier on the site, the supply voltage is 380VAC or 220VAC.

When 3Φ voltage is connected, the efficiency is maximized and the Humidification volume is increased..

Electrode humidifier SYL-00(8Kg/h) / SYL-01(15Kq/h) two models provide the maximum amount of humidification at 380VAC 3Φ voltage.

- Power Consumption

When using 3-phase electricity, the power consumption is calculated as follows:

Power = square root of 3 × voltage × current × power factor

P = √3 × V × I × cosθ

The power consumption of the IEH humidifier can be easily calculated using the following formula.

I = 745 W × Humidifier capacity

Since the IEH humidifier's power factor is 1, the current consumption can be calculated using this equation. For example, when the voltage is 380 V and the set amount of steam is 8 kg/h, the power consumption is 5960 W, and the current consumption is 9 A.

I = 745 × 8 ÷ (1.73 × 380 × 1)

= 5960 ÷ 657

= 9

The operating range should be ±10%, so the humidifier operates in the range of 8-10 A.

When the humidifier capacity is 15 kg/h and 45 kg/h, the current consumption is as follows.

I = 745 × 15 ÷ (1.73 × 380 × 1) = 11175 ÷ 657 = 17 (15 ~ 19 A)	I = 745 × 45 ÷ (1.73 × 380 × 1) = 33525 ÷ 657 = 51 (45 ~ 56 A)

20. Troubleshooting

No	Symptom	Check order	Actions
1	When the power is turned on but cannot operate	Check AC 220V input Check CONTROLLER FUSE Check SH/RE connection Check MONITOR CABLE	Check power supply Replace FUSE Tighten connection bolt
2	When a blower alarm occurs	Check AC 220V R.S phase Check FAN OVERLOAD Check S phase and FAN socket 220V output	Test by changing R.S phase Test RESET return Ask A/S when OV
3	When an error occurs on the LCD display	Check MONITOR CABLE Most of them are wrong when connected due to shortening sensor cable.	Tighten connection bolt Check sensor cable Connect shield wire
4	When a temperature or humidity sensor alarm occurs	Check SENSOR connection line and input/output voltage (DC voltage) V.T.H.G(3.8 output is 100℃,100%)	Tighten connection terminal G and T voltage 0 - 3.8V G and H voltage 0 - 3.8V
5	When a heater overheat alarm occurs	Check overheat prevention T.C	Normal condition : Connection
6	When a compressor alarm occurs	Check HP, LP, OVERLOAD status Check the low pressure of the pipe Check alarm input “A” contact	TRIP return Fill gas Must connect “A” contacts
7	When a water leak alarm occurs	Check the leak detector sensor under the equipment	Insulate with tape between the leak line and the floor
8	When temperature and humidity deviation occurs	Refer to temperature/humidity compensation in test mode
9	How to check by carefully identifying the other contents displayed on the LCD screen	Use test mode	Contact A/S if action is impossible
10	When continuing to enter the test mode after replacing the ROM	Symptoms caused by not having the initial setup	Reset settings in test mode
11	When it is impossible to check each output by up/down key in test mode	Symptoms when “Air blower error” is displayed in test mode
12	When Micom keeps restarting or the fuse is broken	Turn off the power, remove all control outputs and rewire only one	Find the electrical wiring where the problem occurred and remove the cause.
13	If communication does not work when using the remote monitor	Check communication number Check the two communication lines of RX (-) and TX (+)	Must be set to 1 Try swapping RX (-) and TX (+)
14	Monitor cable length limitation Sensor cable length limitation	Possible error when exceeding 20m Possible error when exceeding 30m
