User manual OMRON K3GN V1.03

[. . . ] 1/32 DIN Digital Panel Meter K3GN Compact and Intelligent Digital Panel Meter · A single Panel Meter covering a wide range of applications. 3 main applicable functions: · Process meter (DC voltage/current input). · Easy configuration · Multi-range analog input: applicable for all standard analog signals. 6 input ranges available: 4 to 20 mA/0 to 20 mA, 1 to 5 VDC/ 0 to 5 VDC, ±5 VDC, ±10 VDC. [. . . ] A terminal cover is provided. Main Display Character Size 7 mm 3. 6 mm Application Examples Detection of Dust Exhaust The change in the density of the dust is detected via the E3SA and discriminated by the K3GN. Exhaust Monitoring of Tank Pressure The output of the pressure sensor is processed and the pressure is displayed. Remote monitoring of the operation is possible with the communications function. 4 to 20 mA E3SA K3GN E8AA Pressure Sensor K3GN Host PC Foam RS-485 RS-232C Grinder Dust collecting machine Beer Pump OUT2 (Upper upperlimit alarm) Device stops OUT1 (Upper-limit alarm) Output reduction instruction Tank Exhaust valve 1/32 DIN Digital Panel Meter K3GN K-17 Panel indicators Monitoring of Motor Load Current If the startup time compensation of the K3GN is enabled, the K3GN will not be influenced by the inrush current from starting the motor, and no signal will be output from the K3GN. Power supply* Electromagnetic relay Signal input Monitoring the Remaining Quantity of Soup The distance to the surface of the soup is detected with an ultrasonic sensor and, based on this distance, the K3GN displays the remaining quantity. When the remaining quantity of soup decreases to less than 20%, the K3GN lights the "Replenish" indicator. 24-VDC power supply* E4PA-LS50-M1 Ultrasonic Sensor OUT1 (Upper-limit alarm) K3GN OUT2 (Lower-limit alarm) 4 to 20 mA K3GN 100 % Volume of soup Replenish OUT 1 Large cup Medium cup K3FK CT Converter 20 % Small cup Note: *Power Supply: Recommended DC power supply: eg. OMRON S8VS. Monitoring Difference between Two Line Speeds The difference between the two line speeds is calculated by the PLC and the result is written via RS-485 to the K3GN where it is displayed. RS-485 communications output (calculation result) Monitoring Number of Motor Revolutions Power supply* Signal input 24-VDC power supply* Electromagnetic relay 4 to 20 mA K3GN (Set the input type to "Remote"). OUT1 (Upper limit) 0 to 1 A K3FK CT Converter K3GN-NDC OUT1 (Upper limit) E2E Proximity Sensor OUT2 (Lower limit) K3GN-NDC OUT2 (Lower limit) Position Indication on X-Y Table The position on the X-Y table is calculated by the PLC and the result is written via RS-485 to the K3GN where it is displayed. The scaling function can be used to display the result in millimeter units. PLC Note: *Power Supply: Recommended DC power supply: eg. OMRON S8VS.

Also, do not touch the terminals with a screwdriver while power is being supplied. Use a power supply meeting the power supply specifications of the K3GN. Be sure that the rated voltage is achieved within 2 s after turning ON the power. When installing the K3GN in a panel, be sure that the temperature around the K3GN (not the temperature around the panel) does not exceed 55°C. If the K3GN is subject to radiant heat, be sure that the temperature of the surface of the K3GN exposed to the radiant heat does not exceed 55°C by providing a fan or other heat removal method. after power is ON for correct measurement. !Caution Do not allow metal objects or conductive wire cuttings to enter the product. Doing so may result in electric shock, fire, or malfunction. !Caution Do not attempt to disassemble, repair, or alter the product. Doing so may result in electric shock, fire, or malfunction. !Caution Do not use the product where flammable or combustion gasses are present. Mounting Recommended panel thickness is 1 to 5 mm. Insert the K3GN in the square cutout, insert the adapter from the back, and push the K3GN into the cutout as far as possible. When gang-mounting two or more products in a cutout, be sure that the ambient temperature does not exceed the specifications. Separate the K3GN from machines generating high-frequency noise, such as high-frequency welding machines and high-frequency sewing machines. !Caution The lifetime of output relays varies greatly with the switching capacity and conditions. Consider the actual operating conditions, and use the product within the rated load and electrical service life. !Caution Do not use loads exceeding the rated value. Doing so may result in damage or burning. !Caution Use a power supply voltage within the specified ratings. Not doing so may result in damage or burning. !Caution Be sure to tighten the terminal screws securely. Loose screws may result in product failure or malfunction. Operation A K3GN model with a relay contact or transistor output may not output any alarm signal normally if the model has an error. It is recommended that an independent alarm device be connected to the model. [. . . ] Setting changes using front panel keys prohibited (i. e. , it is not possible to move to the state where changes to settings can be made). 2 · The initial setting is 1. Forced-zero shift Lockout Prohibits the setting or clearing of a forced-zero using the front panel key. Executing and clearing of forced-zero prohibited. ON · The initial setting is OFF. Note: Changes to protection level parameters, moving to advanced function setting level, and moving to calibration level are all allowed. · The initial setting is OFF. K-24 1/32 DIN Digital Panel Meter K3GN Troubleshooting When an error occurs, error details will be displayed on the main display. Confirm the error from the main display and take the appropriate countermeasures. [. . . ]
