2250 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
To display the diagnostic operating conditions listed in Table
3-5, press the limit bypass switch while scrolling up with the
selector. To turn off the diagnostic operating conditions,
press the limit bypass switch while scrolling down with the
selector or turn off the cab power.
See Table 3-8
for a list of abbreviations and notes used in the
tables. See Drum Identification on page 3-61
for
identification of the drums.
NOTE: This topic identifies display readings for all modes
and configurations for the 2250 (to include MAX-
ER). Some of the readings will not appear until the
corresponding mode or configuration is selected.
Some readings may appear even though the crane
is not equipped with the corresponding attachment.
In these cases, the reading is meaningless.
Readings for optional items are marked with an
asterisk (*).
Selecting Display Language
The display can be viewed in English or one of several other
languages. Once the desired language is selected, it will
remain in memory until another language is selected.
To select a different display language, perform both of the
following steps at the same time:
• Press the limit bypass switch.
• Turn the crane mode selector key to confirm.
Repeat the steps until the screen displays the desired
language.
Operating Conditions
Table 3-5 lists the operating conditions that 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 appears on the
display (Figure 3-36
).
Operating Limits
Table 3-6 lists the operating limits that can be displayed.
When one or more operating limits are reached, the
operating limit alert (yellow light and buzzer in cab) turns on
to warn the operator. At the same time, the Operating Limit
screen immediately appears and automatically scrolls
through the names of the limits, stopping at each for
approximately three second (Figure 3-37
).
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 the following
two things happen:
• The name of the limit appears on the display at least
once.
• The cause of the 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 when there are no limits
(Figure 3-38
).
