HANYOUNG NUX T21 Digital Counter and Timer

Thank you for purchasing HANYOUNG product.
Please check whether the product is the exactly same as you ordered. Before using the product, please read this instruction manual carefully. Please keep this manual where you can view at any time.

Product Information

The T21 is an electronic timer manufactured by PT. Hanyoung Electronic Indonesia. It has a voltage input range of 100-230V AC or 24V DC and offers four timing modes: 1, 3, 6, and 3 hours. The timer can be set to intervals ranging from 0.1 seconds to 24 hours and has a maximum time range of 9999 seconds. It also features an ON/OFF delay mode and output power intervals. The T21 has LED indicators for power and pulse width.

Product Usage Instructions

To use the T21 timer, follow these steps:

Connect the timer to a power source within the specified voltage range.
Set the desired timing mode using the selector switch.
Adjust the interval time using the rotary knob. The range for each timing mode is as follows:
- Mode 1: 0.1 sec – 10 min
- Mode 3: 0.3 sec – 30 min
- Mode 6: 0.6 sec – 60 min
- Mode 3H: 0.3 hrs – 24 hrs
Set the ON/OFF delay mode using the selector switch.
Set the output power intervals using the selector switch.
Connect the load to the timer’s output terminals.
Activate the timer by turning the rotary knob clockwise until it clicks.
The LED indicators will display the current status of the timer.
To deactivate the timer, turn the rotary knob counterclockwise until it clicks.

Note: Always refer to the user manual for specific instructions and safety information before operating the T21 timer.

Safety information

Alerts declared in the manual are classified to Danger, Warning and Caution by their criticality.

DANGER: indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury
WARNING: indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury
CAUTION: indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury

Danger

Do not touch or contact the input/output terminals because they may cause electric shock.

Warning

If there is a possibility of an accident caused by errors or malfunctions of this product, install external protection circuit to prevent the accident.
This product does not contain an electric switch or fuse, so the user needs to install a separate electric switch or fuse externally. (Fuse rating : 250 V 0.5 A)
To prevent defection or malfunction of this product, supply proper power voltage in accordance with the rating.
After mounting the product onto a panel, please use a socket dedicated to the product when connecting with other units and do not turn on the power until completing wiring to prevent electric shock.
Since this is not explosion-proof structure, please use in a place where corrosive gas (such as harmful gas, ammonia, etc.), combustible or explosive gas does not occur.
Do not decompose, modify, revise or repair this product. This may cause malfunction, electric shock or fire.
Attach or detach this product while the power is off. Otherwise, it may cause malfunction or electric shock.

Caution

The contents of this manual may be changed without prior notice.
Please check whether the product you purchased is the exactly same as you ordered.
It you use the product with methods other than specified by the manufacturer, there may be bodily injuries or property damages.
Please check whether the product has no damage or abnormality during delivery.
Do not use this product at any place with direct vibration or impact.
Do not use this product at any place with liquid, oil, medical substances, dust, salt or iron contents. (Pollution level 1 or 2)
Do not polish this product by substances such as alcohol or benzene.
Do not use this product at any place with excessive induction trouble, static electricity or magnetic noise.
Do not use this product at any place with possible thermal accumulation due to direct sunlight or heat radiation.
Install this product at place under 2,000m in altitude.
When the product gets wet, the inspection is essential because there is danger of an electric leakage or fire.
If there is an excessive noise from power supply, it is recommended to use insulating transformer and noise filter. The noise filter must be attached to the panel grounded and wiring between the filter output side and power supply terminal should be as shortas possible.
If gauge cables are arranged too closely, the effect on noise may occur.
Do not connect anything to the unused terminals.
After checking polarity of terminal, connect wires to the right position.
Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function.
For the continuous and safe use of this product, the periodic maintenance is recommended.
Some parts of this product have limited life span, and others are changed by their usage.
The warranty period of this product including parts is one year if this product is properly used.
When power is on, the preparation period of contact output is required. In case of using signals of external interlock circuit, use a delay Relay.
