During commissioning, the pump will operate at the factory settings.
• The service menu deals with the setting and converting of individual
pumps; see Section 8 "Operation" on page 67.
• To correct faults, also see Section 11 "Faults, causes and remedies" on
page 87.
CAUTION! Risk of material damage!
Modifying the settings for the differential pressure sensor can lead
to malfunctions. The factory settings are configured for the sup-
plied Salmson differential pressure sensor.
• Default value: input In = 0-10 volts,
pressure value correction = ON
• When using the supplied Salmson differential pressure sensor,
these settings must not be changed!
Modifications are only needed if another differential pressure
sensor is used.
At high ambient temperatures, the thermal load on the module can be
reduced by lowering the switching frequency (menu <4.1.2.0>).
NOTE
The switching frequency can only be changed via the CAN bus
or IR-PDA.
Lower switching frequencies result in increased noise levels.
If the menu <5.7.2.0> "Pressure value correction" is not available on
the display of a given pump, that pump is a variant in which the fol-
lowing functions are not available:
• Pressure value correction (menu <5.7.2.0>)
• Efficiency-optimised activation and deactivation in double pumps
