3. HIGH LAMP
This red lamp signals that the
level is above the high setpoint.
4. LOW LAMP
This red lamp signals that the
level is below the low setpoint.
5. FLOATS LAMP
This red lamp will be on if the
system has had a float backup
cycle since the last reset or
power up.
6. XDUCER LAMP
This red lamp signals that
the main level sensor input is
outside of its normal range of
4 to 20 milliamps. This means
that either the transducer or the
NOVUS 4000 input has failed.
7. ALT SWITCH
The alternate switch will turn
alternation on when up and off
when in the center position.
When it is pushed down the
lead pump will be sequenced to
the next available pump. The
current lead pump is indicated
on the first line of the display.
8. MENU BUTTON
This button is depressed and
held for 10 seconds to enter the
setpoint menu.
9. UP / YES BUTTON
This button has several
functions depending on the
mode of the controller.
When the controller is in
normal mode (not in one of
the menus) this button causes
the bottom line of the display
to sequence between pump
status and the three elapsed
time meters. After 15 seconds
the bottom line of the display
always reverts to pump status
in normal mode.
When the controller is in one
of the two menus this button is
used to increment the current
parameter being adjusted or to
tell the system to save the new
value.
10. DN / NO BUTTON
This button has several
functions depending on the
mode of the controller.
When the controller is in
normal mode (not in one of
the menus) this button caused
the bottom line of the display
to sequence between the pump
status and the three elapsed
time meters.
When the controller is in one
of the two menus this button is
used to decrement the current
parameter being adjusted or to
tell the system not to save the
new value.
11. MUTE / RESET BUTTON
This button will reset any
current latched up alarms such
as temp fail or on floats. It
will also silence the horn if an
alarm is currently active.
12. TEST / ADJUST BUTTON
AND KNOB
The function of these two
operators depends on the mode
of the controller.
When the controller is in the
normal (not menus) mode
these operators are used to
test the system. When the
TEST button is depressed and
held the ADJUST knob will
be the level for the system.
As you turn the knob up and
down the level will go up and
down. This will call on pumps
and make alarms just as if the
level was coming from the
transducer. The controller will
switch back to the transducer
8 seconds after the button is
released.
When the controller is in one
of the menus these operators
are used to change the value
of the setpoint or parameter.
Depressing and holding the
ADJUST button will cause
the knob value to be placed
in the current parameter or
setpoint. This can be used
along with the up and down
buttons to easily adjust all of
the setpoints.
13. 32 CHARACTER DISPLAY
This alpha-numeric display
has two lines of 16 characters
each. The first line always
displays the current level in
feet and the current lead pump.
The second line depends on
the mode of the controller.
In normal mode this line
displays pump status or the
elapsed time meters. Pressing
the up or down buttons will
sequence through the three
elapsed time meters. After 15
seconds this line will revert
to pump status. When pump
status is displayed the display
will read ALL PUMPS OK
if there are no pump faults.
If there are pump faults such
as temperature failures or seal
failures they will be displayed
one at a time every 2 seconds.
In either of the two menus
the second line of the display
shows the parameter being
adjusted and its current value.
