Parameter 74.1 ESP control word (page
controls enable/disable status of the function.
See Terms and abbreviations (page
Defines time setting for periodic cleaning schedule.
When parameter 81.81 Since last cleaning
reaches the value set in this parameter, the cleaning
request is automatically generated.
After cleaning operation is completed, the timer is then
reset for another round with parameter
cleaning which displays remaining time till the next
cleaning request based on this parameter time setting.
Note: For the time trigger to work, parameter
Pump cleaning option
Time trigger in hours.
Defines the desired quantity of cleaning cycles.
Each cycle consists of two speed steps with period of
off-time after each step. The period and dynamics of
each cycle are defined with parameters
reference...81.32.

First step reference in percentage.
Defines the time period for the first step of cleaning
cycle.
First step time in second.
Defines the time period for the pause after each step.
The speed reference will be zero during Off time.
Off time in seconds.
Defines speed reference for the second step of cleaning
cycle.
Note that the parameter
is also taken into use for the cleaning operation.
Second step reference in percentage.
Defines the time period for the second step of cleaning
cycle.
Second step time in seconds.
Defines acceleration time for the cleaning operation.
Cleaning acceleration time in seconds.
Defines deceleration time for the cleaning operation.
