1. Depress the MENU button and
hold it until the first setpoint
appears on the bottom line of
the display. This will take
about 10 seconds.
2. The display should say LEAD
ON = XX.X FT. where XX.X
is the current value for the lead
pump on setpoint.
3. If you wish to change this value
then use the UP or DOWN
buttons or you can hold the
ADJUST button down and
turn the ADJUST knob until
the value is correct. After the
value is correct then depress
the MENU/NEXT button to go
to the next setpoint.
4. If you have changed the
value then the displays will
ask SAVE? (Y/N). If you
wish to save the new value
then press UP/YES if not
then press DOWN/NO. The
display should change to the
next setpoint.
5. The display should say LEAD
OFF = XX.X FT. where XX.X
is the current lead off setpoint.
Repeat steps 3 and 4 above to
make any changes you need to
this setpoint.
6. This process should be repeated
until all of the setpoints have
been examined and changed
or until no further changes are
required. Once all setpoints
have been done the screen
will return to normal mode
or you can, at any time, hit
the MUTE/RESET button and
return to normal mode.
If the system is set up for 2 pumps
then the setpoints for the lag2
pump will be skipped in the menu.
If the system is set up for only 1
pump then the setpoints for both
lag pumps will be skipped.
The setpoints are stored in
electrically erasable programmable
memory EEPROM which will not
lose its contents when powered
down. This is done every time
the operator answers YES to the
SAVE? (Y/N) prompt.
Configuration
Menu
This menu is used to configure
the NOVUS 4000 controller for
its application. This is normally
only done once (when the panel
is built or at startup) and would
not be required again unless the
configuration changed. This menu
is entered using the following
procedure:
1. Depress the UP and DOWN
buttons at the same time and
hold them until the first setting
is displayed on the bottom line
of the display. This will take
about 10 seconds.
2. The display should say MAX
LEVEL XX.X FT where
XX.X is the current value.
This parameter is the level
when the level transmitter is
at 20 Ma. (full scale). For
example, if the transducer is a
10 psig submersible pressure
transducer then 10 psi is 23.1
feet so adjust this value to
23.1.
3. If no change to this setting is
required then press the MENU/
NEXT button. To change
this value we use the same
procedure that we used on the
setpoint menu. Use the UP or
DOWN buttons or depress the
ADJUST button while turning
the ADJUST knob. After you
have the value required depress
the MENU/NEXT button to go
to the next parameter.
4. If the parameter has changed
then the display will ask
SAVE? (Y/N). If the value is
correct then press the UP/YES
button to save it, or press the
DOWN/NO button to continue
without saving the new setting.
5. The display should say
OFFSET XX.X where XX.X
is the current value. This
parameter is the level when
the level transmitter is at
4 Ma. For example, if the
transmitter is a submersible
pressure transducer mounted 6
inches off the floor of the wet
well then this setting should
be 00.5 ft. Use the procedure
in steps 3 and 4 above to make
any changes and go to the next
parameter.
6. The display should say HOW
MANY PUMPS X where X
is the current max number of
pumps. If this is a duplex
station set this to 2. If it is a
triplex station then use 3. Use
the procedure in steps 3 and
4 above to make any changes
and go to the next parameter.
7. The display should say START
DELAY XXXS where XXX
is the current delay between
pump starts. This parameter
is the minimum time between
starting one pump and then
starting another. It is set in
seconds from 0 to 255. Use
the procedure in steps 3 and
4 above to make any changes
and go to the next parameter.
8. The display should say STOP
DELAY XXXS where XXX
is the current delay between
pump stops. This parameter
is the minimum time between
stopping one pump and then
stopping another. It is set in
seconds from 0 to 127. Use
the procedure in steps 3 and
4 above to make any changes
and go to the next parameter.
9. The display should say TIME
AT SP XXXS where XXX is
