●Precautions

WARNING

Do not touch the terminals while power is being supplied. Doing so may possibly result in electric shock. Make sure that the terminal cover is installed before using the product.

Always provide protective circuits in the network. Without protective circuits, malfunctions may possibly result in accidents that cause serious injury or significant property damage. Provide double or triple safety measures in external control

circuits, such as emergency stop circuits, interlock circuits, or limit circuits, to ensure safety in the system if an abnormality occurs due to malfunction of the product or another external factor affecting the product's operation.

CAUTION

Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction.

Do not use the product in locations where flammable or explosive gases are present. Doing so may occasionally result in minor or moderate explosion, causing minor or moderate injury, or property damage.

Do not attempt to disassemble, repair, or modify the product. Doing so may occasionally result in minor or moderate injury due to electric shock.

Do not use the equipment for measurements within Measurement Categories II, III, and IV for K3HB-R, K3HB-P, and K3HB-C (according to IEC61010-1). Doing so may occasionally cause unexpected operation, resulting in minor or moderate injury, or damage to the equipment. Use the equipment for measurements only within the Measurement Category for which the product is designed.

Perform correct setting of the product according to the application. Failure to do so may occasionally cause unexpected operation, resulting in minor or moderate injury, or damage to the equipment.

Ensure safety in the event of product failure by taking safety measures, such as installing a separate monitoring system. Product failure may occasionally prevent operation of comparative outputs, resulting in damage to the connected facilities and equipment.

Tighten the screws on the terminal block and the connector locking screws securely using a tightening torque within the following ranges. Loose screws may occasionally cause fire, resulting in minor or moderate injury, or damage to the equipment. Terminal block screws: 0.43 to 0.58 N·m

Connector locking screws: 0.18 to 0.22 N·m

V

CAUTION

Make sure that the product will not be adversely affected if the DeviceNet cycle time is lengthened as a result of changing the program with online editing. Extending the cycle time may cause unexpected operation, occasionally resulting in minor or moderate injury, or damage to the equipment.

Before transferring programs to other nodes or changing I/O memory of other nodes, check the nodes to confirm safety. Changing the program or I/O memory of other nodes may occasionally cause unexpected operation, resulting in minor or moderate injury, or damage to the equipment.

VI

Precautions for Safe Use

(1)Do not use the product in the following locations.

•Locations subject to direct radiant heat from heating equipment

•Locations where the product may come into contact with water or oil

•Locations subject to direct sunlight

•Locations where dust or corrosive gases (in particular, sulfuric or ammonia gas) are present

•Locations subject to extreme temperature changes

•Locations where icing or condensation may occur

•Locations subject to excessive shocks or vibration

(2)Do not use the product in locations subject to temperatures or humidity levels outside the specified ranges or in locations prone to condensation. If the product is installed in a panel, ensure that the temperature around the product (not the temperature around the panel) does not go outside the specified range.

(3)Provide sufficient space around the product for heat dissipation.

(4)Use and store the product within the specified temperature and humidity ranges. If several products are mounted side-by-side or arranged in a vertical line, the heat dissipation will cause the internal temperature of the products to rise, shortening the service life. If necessary, cool the products using a fan or other cooling method.

(5)The service life of the output relays depends on the switching capacity and switching conditions. Consider the actual application conditions and use the product within the rated load and electrical service life. Using the product beyond its service life may result in contact welding or burning.

(6)Install the product horizontally.

(7)Mount to a panel between 1 and 8-mm thick.

(8)Use the specified size of crimp terminals (M3, width: 5.8 mm max.) for wiring. To connect bare wires, use AWG22 (cross section: 0.326 mm2) to AWG14 (cross section: 2.081 mm2) to wire the power supply terminals and AWG28 (cross section: 0.081 mm2) to AWG16 (cross section: 1.309 mm2) for other terminals. (Length of exposed wire: 6 to

8 mm)

(9)In order to prevent inductive noise, wire the lines connected to the product separately from power lines carrying high voltages or currents. Do not wire in parallel with or in the same cable as power lines. Other measures for reducing noise include running lines along separate ducts and using shield lines.

(10)Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON.

(11)Allow the product to operate without load for at least 15 minutes after the power is turned ON.

(12)Do not install the product near devices generating strong high-frequency waves or surges. When using a noise filter, check the voltage and current and install it as close to the product as possible.

(13)Do not use thinner to clean the product. Use commercially available alcohol.

(14)Be sure to confirm the name and polarity for each terminal before wiring the terminal block and connectors.

(15)Use the product within the noted supply voltage and rated load.

VII

(16)Do not connect anything to unused terminals.

(17)Output turns OFF when the mode is changed or settings are initialized. Take this into consideration when setting up the control system.

(18)Install an external switch or circuit breaker that complies with applicable IEC60947-1 and IEC60947-3 requirements and label them clearly so that the operator can quickly turn OFF the power.

(19)Use the specified cables for the communications lines and stay within the specified DeviceNet communications distances. Refer to the User's Manual (Cat. No. N129) for details on communications distance specifications and cables.

(20)Do not pull the DeviceNet communications cables with excessive force or bend them past their natural bending radius.

(21)Do not connect or remove connectors while the DeviceNet power is being supplied. Doing so will cause product failure or malfunction.

(22)Use cables with a heat resistance specification of 70ºC min.

VIII

●Noise Countermeasures

Do not install the product near devices generating strong high-frequency waves or surges, such as high-frequency welding and sewing machines.

(1)Mount a surge suppressor or noise filter to peripheral devices generating noise, in particular, motors, transformers, solenoids, and magnet coils.

2.2 Using I/O

■ Wiring

Use crimp terminals suitable for M3 screws, as shown below.

			5.8 mm max.
			5.8 mm max.
			Use cables with a heat resistance of at least 70ºC.
	●Power Supply
	A B C D	E	Supply power to terminal numbers A1 and A2. The power supply
			specifications are outlined below.
	1
			100 to 240 VAC, 50/60 Hz, 18 VA max. (at max. load)
	2
	3		24 VAC/VDC, 50/60 Hz, 12 VA max./7 W max. (at max. load)
	4
	5		(No polarity)
	6

When the power is turned ON, a power supply capacity greater than the rated power supply is required. When multiple Units are being used, make sure that the operating power supply has sufficient capacity.

Complying with UL/CSA Standards

Use an SELV power supply with overcurrent protection for the DC power supply. An SELV power supply has double or reinforced insulation between the input and output, an output voltage of 30 V rms and 42.4 V peak, and is 60 VDC or less.

Recommended Power Supply: S8VS-06024@ (from OMRON)
