Setup Screen 5
This screen allows the user to specify the operating
parameters for off-board, integrated tanks and indicate
which positions have level sensors installed. See the the
appropriate Tank Stand manual for information about
installing level sensors. See Related Manuals on page
2. The user may select from the following refill settings:
Disabled, Monitor, Manual, Auto Top-Off.
The following describes the system operation when
each tank mode is selected.
Disabled:
Disable tank operation.
Monitor:
The top sensor generates a high level deviation and
the bottom sensor generates a low level deviation.
Refill is not supported, and no button is provided on
the run screens to initiate refill.
Errors will clear when the corresponding condition
clears.
Manual:
The low level sensor will generate a low level devia-
tion.
An icon is shown on the Run screens to initiate a
manual refill operation at any time.
Manual refill will continue until either the high level
sensor sees material, the user abouts the refill via
the refill button on the run screens, or the refill
time-out expires.
The low level alarm will clear when the condition
clears.
Auto Top-Off:
3A6165J
The low level sensor will generate a low level devia-
tion.
When the high level sensor does not see material,
automatic refill will begin and continue until either
the high level sensor sees material or until the refill
time-out expires.
The low level deviation will clear when the condition
clears.
An icon is shown on the Run screens to initiate an
automatic refill operation at any time.
This icon can also be used to abort a refill operation.
Refill Setting: If a refill setting other than Disabled is
selected, the user must set at least two level sensor
locations as installed by checking the check box on the
screen. If all three locations are set to installed, the sys-
tem will default to the Auto-Top Off refill setting and
operate as follows:
The low level sensor will generate a low level devia-
tion.
The high level sensor will generate a high level devi-
ation and abort any automatic refill operation.
When the middle sensor is not satisfied, automatic
refill will begin and will run until either the middle
sensor is satisfied, the high level sensor generates
a deviation (if the middle sensor fails), or the refill
time-out expires.
The low level deviation and the high level deviation
will clear when the condition clears.
An icon is shown on the Run screens to initiate an
automatic refill operation at any time. This icon can
also be used to abort a refill operation.
Refill Timeout: The refill timeout setting may be set by
the user as a means to abort the refill in the case of a
high level sensor failure. When an automatic refill
begins, the time-out counter will begin to count down. If
the timer expires before the high level sensor is satis-
fied, the refill will abort.
