For the problem that the Omron photoelectric switch only lights green, it may be because a component on the circuit board is faulty or damaged, or because of the poor connection of a component on the circuit board. So, to deal with this, the first thing to do is to see if the components on the board are ...

Fault 1: Do not exceed the rated voltage of the load current during the use of the OMRON relay, because when the applied rated voltage is too large, it may cause a local short circuit between the cores of the OMRON relay coil and poor operation of the AC operation relay. And there are ...

1. The internal components of Omron switch are not in good contact. 2. Omron switch malfunction. 3. The Omron switch is fused. 4. The insulation performance of Omron switch becomes weaker. ...

1. The optical power meter is not accurate, the domestic optical power meter can only test the equipment with small optical power output, and cannot test the EDFA with high power output, and the optical power meter of the optical amplifier must be imported originally, and the inaccurate instrument can not be used as a standard. 2. The flange of the output port is damaged ...

1. Top button switch: suitable for occasions that require frequent pressing, such as video game consoles, calculators, etc. 2. Side button switch: suitable for occasions that need to be pressed on the side, such as mobile phones, remote controls, etc. 3. Knob switch: suitable for occasions that require rotary operation, ...

The E4 fault code usually appears on the display of the blood pressure monitor, indicating that the blood pressure monitor is poorly connected to the cuff or that the cuff is falling off. This failure can lead to inaccurate measurement results or even inability to complete the measurement. Solution(s): 1. Check that the cuff is worn correctly and whether it is loose...

1. Ambient temperature The specification of the sensor will rule the ambient temperature range of the normal operation of the sensor, such as 40-85 degrees, which varies depending on the product model. It is advocated not to exceed the temperature range specified in the specification book, beyond the normal operating temperature range of the sensor, ...

The sensor can be fixed in two ways: PCB and disc mounting 1. PCB installation method In general, the primary measurement signal of the PCB-mounted sensor is relatively small. The output terminal of the sensor adopts the way of pi pin or SMD, which can be performed according to the welding process of the general device in soldering.

1. In the Omron PLC programming software, select the program segment to use the hold relay command. 2. Insert the holding relay command in the program section and assign the appropriate opcode to it. 3. Modify the status of the hold relay command, for example, the hold relay needs to be kept ...

The connection method is as follows: the brown wire is connected to the PLC input point, the PLC com point is connected to the positive pole of the power supply, and the negative pole of the power supply is connected to the blue wire. NPN type: brown is connected to the positive power supply, blue is connected to the negative power supply, the black wire is connected to the PLC input point, and the PLC com point is connected to the positive power supply. NPN is a leak type, and the detected object ...

1. Click [Controller] - [Mode] - [Programming Mode]. 2. Click [Yes] in the pop-up window, and at this time, the PLC is in programming mode. 3. Click [Controller] - [Clear All Memory]. 4. Click [OK], and the PLC memory is successfully ...

1. Fault phenomenon: After powering on, the power supply does not respond. 2. Cause of failure: (1) The input power supply voltage is insufficient and does not reach the specified range. (2) The input power supply voltage is instantaneously impulsed, resulting in damage to the input components (such as fuses, rectifications, etc.) as shown in the figure: ...
