• 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 sen-
sor 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 be changed via the menu, the CAN bus
or the IR-PDA.
Lower switching frequencies result in increased noise levels.
If menu <5.7.2.0> "Pressure value correction" is not available on the
display for a pump, this is a variant of the pump in which the following
functions are unavailable:
• Pressure value correction (menu <5.7.2.0>)
• Flow rate trend display
DANGER! Danger of death!
Incorrect installation and improper electrical connections can
result in a risk of fatal injury.
• Have the electrical connections established by approved electri-
cians only, in compliance with the applicable regulations.
• Accident prevention regulations must be observed!
DANGER! Danger of death!
Failure to install safety devices on the module cover or near the
coupling can cause electrical shock or contact with rotating parts,
potentially resulting in life-threatening injuries.
• Before commissioning, all safety devices such as module covers or
coupling covers that were removed must be reinstalled.
CAUTION! Risk of property damage!
Risk of property damage if the module is not installed.
• Normal operation of the pump is only permitted with the module
installed.
• The pump is not allowed to be connected or operated without the
module installed.
CAUTION! Risk of property damage!
Danger of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.
CAUTION! Damage to the pump by overheating!
The pump must not be allowed to operate dry for more than 1
minute. Dry running causes a build-up of energy in the pump,
which can damage the shaft, impeller, and mechanical seal.
• Make sure that the volume flow does not go below the minimum
value Q .
