operational parameters have been input by the user and
saved in the microcontroller memory.
• Motor – Displays the motor hour meter and on/off cycle
counter (non-resettable).
• Low Volt – Displays the low voltage hour meter
(non-resettable).
• Advance – Displays the solenoid hour meter and on/off cycle
counter for torque wrench advance cycles (non-resettable).
• Retract – Displays the solenoid hour meter and on/off cycle-
counter for torque wrench retract cycles (non-resettable).
• Local – Switches the pump Local mode ON or OFF.
• Language – Sets the language of the display to English,
Spanish, French, Italian, German or Portuguese, with
English being the default setting.
• Diagnose – Displays input signals from the pendant and other
electrical accessories.
• Calibration – Allows calibration of pump pressure transducer
(hidden menu - accessed from the Units menu).
6.5 LCD Menus
See the following paragraphs for descriptions of the LCD menus.
Also refer to Table 1, Quick Reference Chart (QRC), located after
Section 9.0.
6.5 A “Normal Operation” Menu
READY
0
Screen 1
PSI
(See Screen 1) LCD screen “READY”
indicates that the microcontroller has
booted successfully. The pressure or
torque reading will be “0” when pump
is fi rst connected to power and motor
is off. Enter into the remaining menus
by pressing the Menu button. Refer to
QRC step #1.
6.5 B “Units” Menu
SET UNITS
PSI MPa
BAR Nm
Ft-lb
Screen 2
(See Screen 2) This screen allows the
operator to set the unit of pressure-
measurement by pressing the Up
or Down Arrow buttons. PSI, BAR,
Mpa, Nm and Ft-lb are the available
choices, with PSI being the default.
Save setting and step forward by
pressing the Menu button. Refer to
QRC step #2.
6.5 C “Torque Wrench Model Selection” Menu
(Available only if “Ft-lb” or “Nm” is selected)
SET
Screen 3
SQD 160 I
(See Screen 3) If foot pounds (Ft-lb)
or Newton Meters (Nm) is selected in
the Units menu (Section 6.5 B), a list
of Enerpac torque wrench models
will be shown on this screen. Scroll
through the list of available models
using either the Up or Down Arrow
button. Press the Menu button to
select the desired model. Refer to
QRC step #3.
6.5 D “Automode” Menu
SET
Screen 4
ON
AUTOMODE
(See Screen 4) Toggle Automode ON
or OFF by pressing either the Up or
Down Arrow button. Save setting and
step forward by pressing the Menu
button. Refer to QRC step #4.
Notes:
• If PSI, BAR or MPa is selected, the Automode menu will
appear after the Units menu (when the Menu button is pressed).
However, if Ft-lb or Nm is selected, the Automode menu will
appear after the Torque Wrench Model Selection menu.
• If Ft-lb or Nm is selected and Automode is OFF: The Torque
Value Selection menu (See Section 6.5 E) will not be available,
and any previously set torque value will have no effect on
the pump. The microcontroller will set the advance torque to
the maximum allowable torque value for the wrench model
selected.
• If PSI, BAR or MPa is selected and Automode is OFF: The
Hi Press menu (See Section 6.5 F) will not be available, and
any previously set Hi Press value will have no effect on pump
operation. The microcontroller will set the advance pressure to
the maximum allowable value for your pump type.
• Whether Automode is ON or OFF, the maximum pressure or
torque will be limited by the relief valve setting (See Section
5.2).
6.5 E “Torque Value Selection” Menu
(Available only when Automode is ON and “Ft-lb” or
“Nm” is selected)
SET
Screen 5
10000
SQD 160 I
Ft-lb
(See Screen 5) After selecting the
torque wrench model, the maximum
advance torque value will be displayed,
either in foot pounds (Ft-lb) or Newton
Meters (Nm). If necessary, reduce the
value by pressing the Down Arrow
button. When the desired torque is
shown, press the Menu button for
3 seconds and the Main menu (See
Section 6.5 G) will appear. Refer to
QRC step #4A.
Note: If the Menu button is pressed for less than 3 seconds, the
selected torque value will be saved. However, the Motor menu
(See Section 6.5 I) will appear instead of the Main menu.
6.5 F “Hi Press” Menu (Available only when
Automode is ON and PSI, BAR or MPa is selected)
HI PRESS
7500
SET
Screen 6
PSI
(See Screen 6) This screen allows
the operator to set the advance port
pressure at which the torque wrench
will auto-cycle. 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. Maximum pressure value is 11,600 psi [800
bar] for (-E) pumps and 10,000 psi [700 bar] for (-Q) pumps.
Save setting and step forward to the Main menu (See Section
6.5 H) by pressing the Menu button for 3 seconds. Refer to QRC
step #4C.
Note: If the Menu button is pressed for less than 3 seconds,
the selected Hi Press setting will be saved. However, the Motor
menu (See Section 6.5 I) will appear instead of the Main menu.
