16000 HANGING MAX-ER® OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
MAIN DISPLAY
See Main Display topic in Section 3 of Crane Operator
Manual for detailed instructions on the main display.
The MAX-ER icons always depict a wheeled
counterweight, even when a hanging counterweight is
attached to the crane.
Information Screen
The information screen displays the MAX-ER information
shown in Figure 3-7
and the fault shown in Figure 3-8. Press
scroll button to access the MAX-ER information screens.
There is only one fault that can be activated during hanging
MAX-ER operation:
• Fault # 48 – MAX-ER System Fault which is activated by
a faulty sensor:
- Counterweight lifting cylinder pressure sensor out of
range. Corresponding sensor reads 0 psi (bar)
when cylinder is extending, retracting, or holding the
counterweight OR corresponding sensor reads
7,500 psi (517 bar) when counterweight is on
ground (no load on cylinder).
- Counterweight lifting cylinder position sensor out of
range. Reads 100% when cylinder is retracted.
Reads 0% when cylinder is extended.
- Mast stops compressed too much. The fault will
come on and the mast hoist will be inoperable when
the reading is 0.15 ft (0,046 m).
• Fault # 27 – Mast Stop Retracted
MAX-ER lift and boom hoist up will be disabled. This fault
cannot be bypassed. This fault will also activate if Node-6
electric cables are not connected properly.
NOTE: Fault #27 will only be available with crane software
version M002066 or newer. The MAX-ER mast
stop position information screen will not be
available. See Mast Stop Limit Switch operation
procedure.
