Main Functions 1 display 5.74.2 inch Chinese graphic liquid crystal display, background color gray, clear in direct sunlight, actual weight, rated weight, amplitude, angle, working status, torque percentage, height, when the lifting weight reaches 90% of the rated lifting weight, the sound and light alarm is given, the instrument warning light (yellow) is on, and the buzzer gives intermittent warning sound, the instrument alarm light (red) is on, and the buzzer sends out a continuous alarm sound. 3 the control output can be set to the control point of the crane within the safe range through the setting of the control point. In order to ensure the safety of the crane, after overload, the local system will issue a control signal, allowing the crane to move in a safe direction, prohibit it from continuing to move in a dangerous direction. The torque limiter outputs three pairs of contacts. (240V / 3A) , this control point can be connected to PLC or through the intermediate relay series into the Crane's electrical circuit for over-limit protection control. Three pairs of contacts are as shown in Hook overload control (normally closed) , minimum amplitude control (normally closed) , maximum amplitude control (normally closed) , and small hook overload control (normally closed) . 1 when overload 105% , send control signal, allow up amplitude, put down weight, prohibit down amplitude, or continue to rise. 2 Arm retractions are allowed when the lower limit of the maximum amplitude is exceeded. The upper limit of the amplitude allows the boom boom to be lowered below the minimum amplitude. Other output can be provided according to customer demand, connected to PLC and other functions
