Precautions for Correct Use Application Precautions Short-circuiting Jumper (M2BJ-BTH) • When power is supplied, there is an inrush current of up to 1 A. Confirm that this will not adversely affect operation or damage any devices before using the M2BJ in application. There is no inrush current with DC-only models (M2BJ-@@@-D). • With models that can use both AC and DC, residual energy in the internal capacitor may cause residual sound. Wiring • Perform soldering promptly and correctly at a temperature of 350°C within 3 seconds.Wait for one minute after soldering before exerting any external force on the solder. • If flux is required, use non-corrosive rosin liquid. Ensure that the flux does not penetrate the inside of the case. • In order to improve the reliability of the soldering and to prevent pattern burnout, loop the wire through the terminal hole before soldering. • In order to fit the terminal holes, use lead wires with a nominal cross sectional area of 0.25 mm2 max. • The Buzzer sounds continuously or intermittently depending on how the short-circuiting bracket is attached to the case guide. When the bracket is attached with the triangle on it facing direction A (PC board side), the Buzzer sounds intermittently. • To produce continuous sounds, attach the bracket to the case guide so that the triangle on the bracket faces direction B. • The bracket is set in direction A when ship the product. If the bracket becomes lost, contact your OMRON representative. The model number to order is M2BJ-BTH. Case guide Direction A Direction B Bracket Operating Environment • Do not use the Buzzer in environments where foreign substances may enter the sound outlet. Otherwise, the Buzzer may not sound. Short-circuit Bracket Mounting Location PC board Volume Adjustment Mechanism (M2BJ-BH Only) Bracket • Adjust the volume by turning the control knob on the face of the Buzzer using a screwdriver. Turn to the right to increase the volume and turn to the left to decrease the volume. • Turn the control knob with a torque of 0.98 to 2.94 mN·m.
