6.5 E "LO PRESS" Menu (Available only when
Automode is ON - All except pump type 3)
(See Screen 5) This screen allows
the operator to set the low-pressure
limit at which the pump energizes the
motor / electric valve. Make changes
in increments of 50 psi [3.5 bar] by
pressing either Down or Up Arrow
button once. Press and hold either
button to scroll quickly through the
available settings. Default pressure value is OFF (or "0" on some
pump models). Save setting and step forward to the Main menu
(See section 6.5 F) by pressing the Menu button for 3 seconds.
Refer to QRC step #3C.
Note: If the menu button is pressed for less than 3 seconds, the
selected LO PRESS setting will be saved. However, the Motor
menu (See section 6.5 G) will appear instead of the Main menu.
CAUTION: The LO PRESS value should be set at least
400 PSI below the HI PRESS value to prevent excessive
pump cycling. Use appropriate valving in the hydraulic
circuit to ensure that the pump does not cycle on and off more
than three times per minute. For circuits equipped with sequence
valves, the LO PRESS setting should be at least as high as the
fi rst stage sequence valve pressure.
6.5 F Main Menu
(See Screen 6A) When Automode is
fi rst turned on, the screen will display
"AUTO".
(See Screen 6B) During
operation, and after Automode has
taken control of the pump, the text will
change from "AUTO" to "AUTO ON".
All except pump type 3: If a LO
PRESS value has been entered, the
pump backlight will begin to fl ash on
and off. This fl ashing will continue
until system pressure drops to the LO
PRESS value.
Note: Details of Automode operation
will vary, depending on pump type and
model. Refer to sections 4.0 and 4.1
for additional information. Also refer to
the pump model matrix in Table 4 near
the end of this document.
(See Screen 6C) If Automode is OFF, the
screen will display "READY" instead of
"AUTO", and the system pressure will
appear on the numeric display.
Note: For pumps NOT equipped with
a pressure transducer, the screen will
display "READY" and no pressure will
be indicated. The "AUTO" and "AUTO
ON" screens will not be available.
6.5 G "Motor" Menu
(See Screen 7) This screen allows the
operator to read the number of hours
or on/off cycles the motor has been
operated. Toggle between hours and
cycles by pushing either the Down
or Up Arrow button. Step forward by
pressing the Menu button. Refer to
QRC step #5.
