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

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.
