DIGITAL DISPLAY READINGS
General
The digital display and selector (see Operating Controls
topic) allow the operator to monitor three groups of crane
information: operating conditions, operating limits, and
system faults.
Depress top or bottom of selector to scroll up and down
through the display readings. Release selector when the
desired information is displayed.
To display diagnostic operating conditions listed in Table 3-2
,
depress limit bypass switch while scrolling up with selector.
To turn off the diagnostic operating conditions, depress limit
bypass while scrolling down with selector or turn off cab
power.
See Table 3-5
for a list of abbreviations and notes used in the
tables. See Drum Identification topic for identification of the
drums.
NOTE: This section identifies display readings for all
modes and configurations the 2250 can be used in
(to include MAX-ER). Therefore, some of the
display readings identified will not appear until the
corresponding mode or configuration is selected.
Also, some display readings may appear even
though the crane is not equipped with the
corresponding attachment. In these cases the
display reading is meaningless.
Display readings for optional items are marked with
an asterisk (*).
Operating Conditions
Table 3-2 lists operating conditions which can be displayed
and the normal operating range of each.
When an operating condition is selected (such as ENGINE
SPEED), the current status of the condition displays (see
Figure 3-12
).
Operating Limits
Table 3-3 lists operating limits which can be displayed.
When one or more operating limit is reached, the operating
limit alert (yellow light and buzzer in cab) turns on to warn the
operator. At the same time, the operating limit display
immediately appears (see Figure 3-13
) and automatically
scrolls through the names of the limits, stopping at each for
approximately three seconds.
The operating limit alert turns off when the cause of each
limit is corrected. The name of each limit reached during
operation is retained in memory, however, until two things
happen:
1. Name of limit appears on display
2. Cause of limit is corrected
For this reason, it is normal for the names of limits to appear
when you scroll to the operating limit group, even when the
operating limit alert is off.
To erase the names of inactive limits, scroll to the operating
limit group. Wait until the display scrolls through the name of
each limit. The names of inactive limits will be erased
automatically. If the alert is on, only the names of active limits
will remain.
NO FAULT appears on the display (see Figure 3-14
) when
there are no limits.
System Faults
Table 3-4 lists system faults which can be displayed.
When one or more system faults occur, the system fault alert
(red light and beeper in cab) turns on to warn the operator. At
the same time, the system fault display immediately appears
(see Figure 3-15
) and automatically scrolls through the
names of the faults, stopping at each for approximately three
seconds.
The system fault alert turns off when the cause of each fault
is corrected. The name of each fault that has occurred during
operation is retained in memory, however, until two things
happen:
1. Name of fault appears on display
2. Cause of fault is corrected
For this reason, it is normal for the names of faults to appear
when you scroll to the system fault group, even when the
system fault alert is off.
To erase the names of inactive faults, scroll to the system
fault group. Wait until the display scrolls through the name of
each fault. The names of inactive faults will be erased
