The Panel (B 50)
This control unit is located in the operator's cab.
It contains
- load moment meter
- boom angle meter
- program selection switch
- switch for horn
- signal lights
- warning horn
- angle preset system
The correct switch position MUST be selected by the operator or a possible incorrect rating condition will result. The
left meter indicates total load moment. It is divided into three separate color-coded segments GREEN, YELLOW, and
RED representing APPROVED, CAUTION , and PROHIBITED, respectively. When the load moment indicator shows
RED, further boom extension, boom lowering and hoisting up is prohibited.
Indication of the right indicator is boom angle. At preset for angle range selection the right of the two rotating knobs
can be set at the maximum desired, required or imposed boom angle and the left knob can be set at the minimum
boom angle.
Once these angles are exceeded, the red warning light will come on and the horn will sound. Horn and warning light
are overlooked at a less than O0 position of the left knob.
