NOTICE
If a mains disconnection is planned for a longer period of time, the pump
kick must be taken over by an external control by briefly switching on the
mains voltage.
For this purpose, the pump must be switched on at the control side before
the mains disconnection.
The ramp times of the pumps can be set in the menu

The ramp times define the maximum speed at which the pump may ramp up and down when
the setpoint is changed.
The adjustable value range for ramping up and down is between 0 s and 180 s. For the fact-
ory setting, see "Factory setting" [" 198] section.
The function "Automatic PWM frequency reduction" can be switched on and off in the
menu "Settings", "Additional settings":

The function is available depending on type.
The "Automatic PWM frequency reduction" function is switched off in the factory.
If the ambient temperature of the pump is too high, the pump independently reduces the
hydraulic output.
If the "Automatic PWM frequency reduction" function is activated, the switching frequency
changes from a critical temperature in order to continue supplying the required hydraulic op-
erating point.
NOTICE
A changed switching frequency can lead to higher and/or changed operat-
ing noises of the pump.
In order to support fault analysis, the pump provides additional help apart from fault noti-
fications:
Diagnostics help is used for diagnosis and maintenance of electronics and interfaces. In ad-
dition to hydraulic and electrical overviews, information on interfaces and unit information
is displayed.
