Also, do not touch the terminals with a screwdriver while power is being supplied. Electrical shock may result via the screwdriver. 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. Use the K3GN within the specified temperature and humidity ranges. 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. Store the K3GN within the specified temperature and humidity ranges. Do not lay heavy objects on the product during use or storage. Doing so may deform or deteriorate the K3GN. 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. To make the K3GN waterproof, insert watertight packing in the K3GN. Install the watertight packing in the proper direction. Note that the packing is direction-sensitive. When gang-mounting two or more products in a cutout, be sure that the ambient temperature does not exceed the specifications. [. . . ] Bring the input value and display value within range. s. err (S. Err) (Flashes at 0. 5-s intervals) Not lit 99999 (Flashes at 0. 5-s intervals) -19999 (Flashes at 0. 5-s intervals) Not lit Not lit Greater than displayable range Less than displayable range 1/32 DIN Digital Panel Meter K3GN K-25 Panel indicators Additional Information Application as a Process Meter The initial settings required when using the K3GN a process meter are explained below using the following example. Setting Example Inputs in the range 1 to 5 V are scaled to the range 0 to 100. 0 kg and displayed. If the measurement value goes over 70. 0 kg, output 1 turns ON. If the measurement value goes below 50. 0 kg, output 2 turns ON. Initial Setting Procedure 1. If a measurement value is displayed (operation level), move to the initial setting level by holding down the Level Key for 3 s min. [. . . ]
