When using the cleaning function for the purpose of periodic maintenance in such applications
that require continuous pump operation for a long time, use a time trigger. The time trigger is
enabled by setting a time period before starting the cleaning operation in Pr. 1479 "Cleaning time
trigger". The timer starts when the timer starting condition is satisfied, and the cleaning operation
is performed at a time interval set in Pr. 1479.
●
Starting conditions of the timer for a time trigger
– When the start command turns ON
– When the cleaning ends
Cleaning operation by the cleaning signal (X97 signal)
●
When the X97 signal is assigned to an input terminal, the cleaning operation can be finished when
the cleaning signal (X97) is turned from ON to OFF.
●
For the X97 signal input, set "97" in any of Pr. 178 to Pr. 189 to assign the function.
