Besides the pendant, which is used to switch the motor on/off and
operate the valves, the CB with its four-button switches is the
main interface between the operator and the pump. With the use
of these four-button switches all functions and settings that are
described in the following can be activated.
CAUTION: Make sure that the plastic overlay, that
protects the LCD screen and the button switches, is not
broken or otherwise damaged. Never punch the button
switches with a sharp or pointed instrument, use fingertips only.
Clean the overlay regularly with a damp cloth; never use
aggressive or abrasive detergents.
A. Boot Sequence
Firmware 5.5 and earlier – When the pump is connected to
electrical power the LCD screen will show: "FIRMWARE x.x" for
2 seconds.
Firmware 5.6 and later – When the pump is connected to electrical
power the LCD screen will show: "FIRMWARE x.x" for 1 second,
then "Model xx" for 0.5 seconds, and then "MOTOR UN/1P/3P"
for 0.5 seconds.
This is setup information about your pump that maybe needed for
service. The boot sequence is finished successfully when the text
display on the LCD screen shows "OK" (sequence takes
approximately 2 seconds).
The micro-controller will automatically recognize the optional
pressure transducer built into the pump. The reading after the
boot process is "OK" in the text display and the current pump-
pressure on the numeric display.
B. LCD Operational Buttons
The CB is equipped with four button switches, from left to right
On/Off / Menu /
• The On/Off button toggles the motor OFF. The motor OFF
function is available on this button even if the pump is NOT in
the local mode but is operated by using the pendant.
• The Menu button enables the operator to step from normal
operational mode into menus. With repeated pressing the
operator steps through the various menus. Pressing the
Menu button also saves any changes made. To return to the
normal operational mode, press and hold the Menu button for
two seconds or don't push any button for 60 seconds.

PSI MPa
BAR
Down Arrow / Up Arrow
• The Down Arrow and Up Arrow buttons serve two purposes.
When the display shows one of the menus, the Down Arrow
and Up Arrow buttons are used to step through the menu's
options. When the pump is placed in Local Mode the Up
Arrow button switches the B and A electric solenoids (the
pendant is non-operational in local mode).
C. Menus Available
The software provides the operator with the following Menus:
• Automode – Set torque wrench Auto Cycle mode ON or OFF.
With Automode OFF, the menu Set Pres (Firmware 5.5 and
earlier) or HI PRESS (Firmware 5.6 and later) will not be
available and the Set Pres or HI PRESS pressure value has no
effect on the pump.
• Set Pres or HI PRESS – (Only available with Automode ON)
Set the Advance port pressure value the torque wrench will
Auto Cycle at. Changes in increments of 50 psi (3.5 bar),
maximum pressure value is 11,600 psi (800 bar) for (-E)
pumps and 10,000 psi (700 bar) for (-Q) pumps. NOTE:
Firmware 5.5 and earlier - the hidden calibration menu for the
digital gauge is accessed from this menu.
• Units - Set the pressure units to PSI / BAR / MPa, with psi
being the default setting. NOTE: Firmware 5.6 and later - the
hidden calibration menu for the digital gauge is accessed
from this menu.
• Motor - display the motor hour meter and on/off cycle
counter (nonresetable)
• Low Volt - display the low voltage hour-meter (nonresetable)
• Advance - display the Advance solenoid hour meter and
on/off cycle counter (nonresetable)
• Retract - display the Retract solenoid hour meter and on/off
cycle-counter (nonresetable)
• Local - set the pump local mode on/off
• Language - set the language of the display to English /
Spanish / French / Italian / German / Portuguese, with English
being the default setting
• Diagnose – display to show input signals from the pendant
and other electrical accessories

6.2 Fault Conditions

Any fault will shut down and prevent pump from starting.
A. Clearing a Fault Condition from the LCD
After the fault causing problem has been corrected, clear the fault
message from the LCD by disconnecting electrical power from the
pump, wait until all characters clear the LCD (~ 10 seconds), then
reconnect power.
