Load Limiter For Crane CLG-SL

CLG-SL Load limiter is an electronic device able to control the load of the crane (or another machine) through a pressure transducer, and limits the operations that would cause an overloading and/or an overturning of the machine, acting on the bypass valve

The green led on the board, in normal operation mode, is lighten to show the power supply. When faults are present, the green led blinks following a particular sequence related to the fault reasons.

Also, it is present a LED bargraph to show the load percentage in real time, compared to the maximum load. When the load exceedes the 100% of the limit, red LED of the bargraph blinks.

Leds placed into the emergency button box (red colour and yellow colour), are lighted in the following situations:

- When emergency button is pressed, the red and the yellow blink together.

- When the load exceedes the 90% of the limit, yellow led is ON.

- When the load exceedes the 100% of the limit, red led is ON.

The CLG-SL load limiter is able to control a Bar LED in order to signal when load exceed the 90% and 100% of maximum permitted load. For this purpose, it is necessary open the box of secondary emergency push button and connect a cable as instructed below.
