GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
Setting the Inner/Outer Working Radius Limitation by
Crane Position
To define and enable the Inner Radius Limitation using the
crane current hook radius as the limitation, the following
steps can be used:
1. Set the RDM screen parameters first. Refer to Using the
Rated Capacity Limiter Display Module (RDM), page
4-159.
2. Using the Jog Dial (5, Figure 4-70), go to the ODM Main
Menu Screen Figure 4-119. Then choose the Working
Range Limiter (WRL) Group Menu Icon
(5, Figure 4-115) by using the Arrow keys
(4, Figure 4-69) or the Jog Dial (5, Figure 4-70).
3. Select the Working Radius Limitation Menu Screen
(5, Figure 4-115). NOTE: The Working Radius Limitation
Icon (8, Figure 4-118) is shown on the top left side of the
ODM screen.
4. Move the Boom to the desired position. This position will
indicate the inner or minimum radius limitation current
value (2, Figure 4-118) position.
5. Enable the limitation by using the Jog Dial
(5, Figure 4-70) or the Arrow Keys (4, Figure 4-69) and
move to the Enable/Disable Switch (1, Figure 4-118).
NOTE: The Switch (1, Figure 4-118) is the
Enable/Disable Switch and is a toggle switch. Toggle to
“I” and click OK (5, Figure 4-69), or the Jog Dial
(5, Figure 4-70) to enable the switch.
6. Use the Jog Dial (5, Figure 4-70) or the Arrow Keys
(4, Figure 4-69) and move to the Limitation Value
(2, Figure 4-118). Click OK to set the current value
Limitation (2, Figure 4-118) position.
NOTE: The current value in Limitation (2) will automatically
populate in the value for Limitation (3).
7. Repeat Steps 4 thru 6, in a similar manner, to set the
Outer or Maximum Radius Limitation (6), (Figure 4-118)
value.
NOTE: The boom is near the limitation so an alarm will
sound. The boom can now be moved away from
the current angle to cease the alarm.
8. The Working Radius Limitation is now defined and
enabled.
Setting the Inner/Outer Working Radius Limitation by
Value
To set parameters and enable the Inner/Outer Working
Radius Limitations using a “typed in” value as the limitation,
the following steps can be used:
1. Set the RDM screen parameters first. Refer to Using the
Rated Capacity Limiter Display Module (RDM), page
4-159.
2. Using the Jog Dial (5, Figure 4-70), go to the ODM Main
Menu Screen. Then choose the Working Range Limiter
(WRL) Group Menu Icon (5, Figure 4-115).
3. Select the Working Radius Limitation Menu Screen
(5, Figure 4-115). NOTE: The Working Radius Limitation
Icon (8, Figure 4-118) is shown on the top left side of the
ODM screen.
4. Enable the limitation by using the Jog Dial
(5, Figure 4-70) or the Arrow Keys (4, Figure 4-69) and
move to the Enable/Disable Switch (1, Figure 4-118).
NOTE: The Switch (1, Figure 4-118) is the
Enable/Disable Switch and is a toggle switch. Toggle to
“I” and click OK (5, Figure 4-69), or the Jog Dial
(5, Figure 4-70) to set the switch. Click OK.
5. Use the Jog Dial (5, Figure 4-70), to move and select the
Limitation (3, Figure 4-118) to set the Inner or Minimum
Radius Limitation value. Enter a value by using the Jog
Dial (5, Figure 4-70) or the upper and lower arrow keys
(4, Figure 4-69) to change the value (in tenths) to the
desired radius value. Use the OK Button (5, Figure 4-69)
to finish entering the values.
NOTE: The Limitation is dependent on the accuracy of the
Hook Radius Calculation, which can be 10%.
6. Once the value is changed to your desired value, again
click OK to finish entering the value. (Note: The alarm
will sound if boom tip is above limit, when enabled).
7. Repeat Steps 4 thru 6, in a similar manner, to set the
Outer or Maximum Radius Limitation (7, Figure 4-118)
value.
NOTE: The boom may now be at the limitation (depending
on the value entered), so alarms may be active.
The boom can now be moved away from the
current boom elevation to cease the alarm, if
needed.
Working Radius Limitation Disable Procedure
To disable an active Inner or Outer Radius Limitation, the
following steps are to be used (note that turning off the power
to the control system also disables the WRL limitations):
1. Select the Radius Limitation Screen (Figure 4-118) on
the Main Menu Screen.
2. Use the Left Arrow and/or Right Arrow Function keys
(4, Figure 4-69) to highlight the Switch Enable/Disable
Symbol (3, Figure 4-119). Enable is “I” and Disable is
“O”.
3. Use the OK Button (5, Figure 4-69), or the Jog Dial
(5, Figure 4-70) to toggle to disable the limitation.
