OMRON NB10W-TW01B (01) PDF MANUAL

When unpacking the NB Unit, check carefully for any external scratches or other damages. Also, shake the Unit gently and check for any abnormal sound.

The NB Unit must be installed in a control panel.

The mounting panel must be between 1.6 and 4.8 mm thick. Tighten the Mounting Brackets evenly to a torque of between 0.5 and 0.6 N-m to maintain water and dust resistance. If the tightening torque exceeds the specified value, or the tightening is uneven, deformation of the front panel may occur. What is more, make sure the panel is not dirty or warped and that it is strong enough to hold the Units.

Do not let metal particles enter the Units when preparing the panel.

Use a DC power supply. Do not connect an AC power supply to the DC power terminals. The DC power supply should have a slight voltage fluctuation and provide a stable output even if the input is momentarily interrupted for 10 ms. The Rated Power Supply Voltage is DC 24V (Allowable range DC 20.4~27.6V).

Do not attempt to take the product apart and do not touch the product inside while the power is being supplied. Otherwise it may result in electric shock.

Always ensure that the personnel in charge confirm that installation, inspection, and maintenance were properly performed for the NB Unit. “Personnel in charge” refers to individuals qualified and responsible for ensuring safety during machine design, installation, operation, maintenance, and disposal.

Ensure that installation and post-installation checks are performed by personnel in charge who possess a thorough understanding of the machinery to be installed.

Do not use the input functions of the touch switch, etc. of the NB Unit, in applications that involve human life, in applications that may result in serious injury, or for emergency stop switches.

Do not attempt to disassemble, repair, or modify the NB Unit. Otherwise it may cause NB Unit to loose its safety function.

Never press at two or more points on the touch panel of the NB Unit at a time. Otherwise, it may activate a switch somewhere between the two points.

In the case of the NB-S Series, when grounding the positive terminal of power supply of 24 V to the NB, do not ground functional grounding terminal at NB side. Some functions of a PC connected to the NB may cause a short circuit and the NB Unit may cause damage.

Depending on the types of PC, SG terminals of RS-232C port or USB port and contour of connector can be connected. As the contour of tool port of the NB and the functional grounding terminal are not insulated they are connected. Therefore, connecting the PC allows GND terminal and functional grounding terminal of the NB to be connected. If the power supply of 24V to the NB is grounded positively, grounding the functional grounding terminal allows a short circuit as shown in the diagram upper right and may result in damage.

The Test Function is performed on PC, and it has different behaviors with actual NB running system. A problem may occur due to communication timing, cable differences and unexpected PC circumstances(such as freeze). When the Test Function is performed, please consider possible unexpected circumstances on the actual NB running system and confirm that any dangerous event will not occur beforehand.

The following precaution must be displayed on all products containing lithium primary batteries with a perchlorate content of 6 ppb or higher when exporting them to or shipping them through California, USA: Perchlorate Material-special handling may apply. See http://www.dtsc.ca.gov/hazardouswaste/perchlorate. The NB Series contains a lithium primary battery with a perchlorate content of 6 ppb or higher. When exporting a product containing the NB Series to or shipping such a product through California, USA, label all packing and shipping containers appropriately.

Do not use benzene, paint thinner, or other volatile solvents, and do not use chemically treated cloths.

Do not dispose the Units together with general waste at waste yards. When disposing them, follow the related local ordinances or rules. Dispose of the Units and batteries according to local ordinances as they apply.

The backlight lamp inside the NB Unit cannot be replaced.

Deterioration over time can cause the touch points to move. Calibrate the touch panel periodically.

Water and oil resistance will be lost if the front sheet is torn or is peeling off. Do not use the Unit, if the front sheet is torn or is peeling off.

The rubber packing will deteriorate, shrink, or harden depending on the operating environment. Inspect the rubber packing periodically.

The communication cables of the COM1 and COM2 connectors are not interchangeable. Confirm the pins of the ports before carrying out communications. (NB3Q-TW00B and NB3Q-TW01B only have COM1.)

Periodically check the installation conditions in applications where the PT is subject to contact with oil or water.

Do not perform a dielectric strength test.

Make the connection by using terminal screws crimping on a twisted-pair cable with a crimping range of 12-26AWG, and only 6.5 mm of insulation peel of the cable needs to be peeled off. Tighten the terminal screws to a torque of between 0.3 and 0.5 N-m. Make sure the screws are properly tightened.

To prevent malfunctions caused by noise, ground the Unit correctly.

Do not touch the packaging part of the circuit board with your bare hands. Discharge any static electricity from your body before handling the board.

When using the No. 6 pin of the serial communication port COM1 connector for a voltage of DC+5V, make sure the supply equipment’s current capacity is below 250mA before using it. The DC+5V voltage output of the NB main unit is +5V±5%, and the maximum current is 250mA. (The serial communication port COM1 of NB3Q-TW00B and NB3Q-TW01B is unable to output the current.)

Do not use the USB memory in an environment subject to strong vibration.

When connecting the equipment with the USB HOST connector, make sure the supply equipment’s current capacity is below 150mA before using it. The DC+5V voltage output of the USB HOST is +5V±5%, and the maximum current is 150mA.

Turn OFF the power supply before connecting or disconnecting cables.

Always keep the connector screws firmly tightened after the communication cable is connected.

The maximum tensile load for connectors is 30 N. Do not apply loads greater than this.

Confirm the safety of the system before turning ON or OFF the power supply, or pressing the reset button.

The whole system may stop depending on how the power supply is turned ON or OFF. Turn ON/OFF the power supply according to the specified procedure.

Once the DIP switch settings are changed, reset by pressing the reset button, or restart the power supply.

To ensure the system’s safety, make sure to incorporate a program that can confirm the normal functionality of the NB Unit before running the system.

Start actual system application only after sufficiently checking screen data, macros and the operation of the program at the host side.

Do not press a touch panel with a force greater than 30 N.

Do not use hard or pointed objects to operate or scrub the screen, otherwise the surface of the screen may be damaged.

Confirm the safety of the system before pressing the touch panel.

Signals from the touch switches may not be input if the switches are pressed consecutively at high speed. Confirm that that the PT has detected the input of a touch switch before pressing any other touch switch.

Do not accidentally press the touch panel when the backlight is not lit or when the display does not appear. Make sure of the safety of the system before pressing the touch panel.

To use numeric input functions safely, always make maximum and minimum limit settings.

Before initializing screen data, confirm that existing data is backed up at the NB-Designer.

When changing the password with the system menu, do not reset or turn OFF the power supply until writing is finished. Failure to save the password may cause the screen to fail to function.
