14. DISPLAY OF SPECIFIC INDICATORS
[1] Working Radius Indicator
Working Radius shall be displayed in unit of “Meter” after so converted and rounded off to one decimal place. (XX.X)
[2] Lifting Height Indicator
Lifting Height shall be displayed in unit of “Meter” after so converted and rounded off to one decimal place. (XX.X)
[3] Boom Angle Indicator
Value of angle θshall be displayed after rounded off to one decimal place. (XX.X)
[4] Boom Length Indicator
Boom Length shall be displayed in unit of “Meter” after so converted and rounded off to one decimal place. (XX.X)
15. OPERATION RANGE LIMITATION CONTROL
At [(Boom Angle Upper Limit) -10°]] > (Boom Angle), control as below shall be active (Safety range):
･ “Boom Angle Upper Limit LED” shall light.
At [(Boom Angle Upper Limit) -7°)] > (Boom Angle) ≧[(Boom Angle Upper Limit) -10°], controls as below
shall be active:
･ “Boom Angle Upper Limit LED” shall flash
･ “Prediction Alarm” output (RS422 ) shall be “ON”.
･ “Boom Angle Upper Alarm” output (RS422 ) shall be “ON”.
At (Boom Angle) ≧ [(Boom Angle Upper Limit) -7°], controls as below shall be active:
･ “Boom Angle Upper Limit LED” shall flash
･ “Prediction Alarm” output (RS422 ) shall be “ON”.
･ “Boom Angle Upper Limit” output shall be “ON”.
･ “Working Status Red Light output” shall be “ON”
At [(Boom Angle Lower Limit) +7°] < (Boom Angle), controls as below shall be active (Safety range):
･ “Boom Angle Lower Limit LED” shall light.
At [(Boom Angle Lower Limit) +4°]] < (Boom Angle) ≦ [(Boom Angle Lower Limit) +7°)] , controls as
below shall be active:
･ “Boom Angle Lower Limit LED” shall flash
･ “Prediction Alarm” output (RS422) shall be “ON”.
･ “Boom Angle Lower Alarm “output (RS422) shall be “ON”.
At (Boom Angle) ≦ [(Boom Angle Lower Limit) +4°] , controls as below shall be active:
･ “Boom Angle Lower Limit LED” shall flash
･ “Prediction Alarm” output (RS422) shall be “ON”.
･ “Boom Angle Lower Limit” output shall be “ON”.
･ “Working Status Red Light output” shall be “ON”
Note:
In the event that Limit Values are not registered (i.e. default mode or canceled mode), “Boom Angle Upper Limit LED”, “Boom Angle
Lower Limit LED”, “Working Radius Upper Limit LED” and “Lifting Height Upper Limit LED” shall be out.
Each limit value shall only be active when the specific functions resume within safety range. In the event that a specific function is
already in alarm range when the limit value is registered, no immediate alarm shall work.
Each registered value shall be stored in memory, even while the power is turned “OFF”.
