COMMAND 11 ALARMS
Depending on the model of crane being calibrated, the computer can put limits on various functions via alarms.
The available alarms with associated limits follow:
•
Free Bm Mode -
This mode allows the operator to select the Main Boom + Manual configuration after the
Manual section (if equipped) is already extended.
NOTE:
If the crane being calibrated has Mode A and Mode B selections, this mode must be set to “NO.”
Damage could result from the wrong selection made.
•
Area Alarm
- This limit activates the Area Alarm. Refer to the crane Operator's Manual for explanation of
the Area Alarms.
•
Low Angle Alarm
- Some models have engine covers that stand tall and could be damaged by the boom or
the boom hoist cylinders. Two alarms are used to warn the operator of the approach to this potential
damage; these are swing arc and boom angle. These alarms have a preset value of:
Low Arc = 70°
Low Ang = 4.5°
Alternate Chart
- allows activation of alternate charts, if available, in the applications part of the System chip.
Load Scale
- is a small scaling factor to allow load trimming. It should not be altered.
Follow the steps on the next page for Command 11.
