Default value
29.08 Pump clean stop mode
Sets the mode for stop used when pump
cleaning forward has finished: Stop ramp
followed by dynamic brake, or dynamic
brake only.
See chapter
7.2.2 Voltage stop ramp
and
7.3.2 Torque stop ramp
for stop ramp
parameters.

INFORMATION
If many pump cleaning cycles are used and run
often, it is recommended to use a one size larger
Softstarter.
WARNING
Pump cleaning is only working when the
Softstarter is connected in-line
WARNING
Because the Pump clean reverse function warms
up the motor we recommend to use a PTC or
PT100 element for temperature monitoring. In
some conditions, the built-in EOL is not accurate
for this feature.
WARNING
Do not use pump cleaning on pumps which have
impeller or rotating shaft parts which can loosen
or jam during reverse rotation. If you do not obey
these instructions, this can cause equipment
damage.
7.22 Fast
take-off
The PSTX is equipped with a fast take-off functionality.
This means that by delaying some non-critical functions,
the time from the start signal is given until the voltage
is applied to the motor is reduced. The Fast take-off
enables motor voltage after approximate 600 ms from
received start signal, which is approximate 500 ms faster
than the regular operation of 1100 ms .
To reduce this time even more the parameter 28.02 Line
contactor close time can be set to 0, default is 250 ms,
see chapter 7.20.2. Then the time for received start to
voltage is applied will approximately be 350 ms and the
regular operation time will approximately be 850 ms.
The parameter 28.43 Motor connection is default Auto
this can be set to the actual motor connection then the
time for received start to voltage will be decreased by
approximately 100 ms.
Note:
Torque control- and dynamic brake performance
might be affected in a minor way in specific situations.
