will cause the motor to be switched off. The corresponding error code is shown on the dis-
play.
The pumps are equipped with an electronic overload protection function which switches
off the pump in the event of an overload.
The electronic modules are equipped with a non-fading memory for data storage purposes.
The data is retained no matter how long the module is disconnected from the power sup-
ply. When the voltage supply is re-established, the pump continues to run with the default
values prior to disconnection from the power supply.
The switching frequency can be changed via menu <4.1.2.0>, the CAN bus or the IR-Stick.
NOTICE
At high ambient temperatures, the thermal load on the elec-
tronic module can be reduced by lowering the switching fre-
quency. Carry out switchovers or changes only when the pump
is at a standstill (not when the motor is running).
Lower switching frequencies result in increased noise levels.
If menu <5.7.2.0> "pressure value correction" is not available for a pump, the pump in
question is a variant version.
In that case, the following functions are unavailable:
• Pressure value correction (menu <5.7.2.0>)
• Efficiency-optimised activation and deactivation in twin-head pumps
• Flow rate trend display
• Installation/dismantling: The technician must be trained in the
use of the necessary tools and fixation materials.
• Observe national and regional regulations!
• Observe locally applicable accident prevention and safety regu-
lations of professional and trade associations.
• Provide protective equipment and ensure that the protective
equipment is worn by personnel.
• Observe all regulations for working with heavy loads.
DANGER
Risk of fatal injury due to lack of protective devices!
Due to missing protective devices of the electronic module or in the
range of the coupling/motor, electric shock or contact with rotating parts
can lead to life-threatening injuries.
• Before commissioning, safety devices such as such as electronic mod-
ule covers or coupling covers that were removed must be reinstalled!
DANGER
Potentially fatal injury due to electronic module not being in-
stalled!
A life-threatening voltage may be present at the motor contacts!
Normal operation of the pump is only permitted with the electronic
module installed.
• Never connect or operate the pump without the electronic module
mounted!
