0.00 hour / real32 Defines time setting for periodic cleaning schedule.
When parameter
81.81 Since last cleaning time counter
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
81.82 Until next
cleaning which displays remaining time till the next
cleaning request based on this parameter time setting.
Note: For the time trigger to work, parameter 81.02
Pump cleaning option sel , bit-2 must be set to 1.
Time trigger 81.19
100 = 1 hour / 100 = 1
hour Time trigger in hours. 0.00 ... 650.00 hour
1 / real32 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
81.21 First step
reference ... 81.32 .
Number of cleaning
cycles 81.20
1 = 1 / 1 = 1 Number of cleaning cycles. 0...65000
-10.00% / real32 Defines speed reference for the first step of cleaning
cycle.
Note that the parameter
75.15 Starting speed setting
is also taken into use for the cleaning operation.
First step reference 81.21
100 = 1% / 100 = 1% First step reference in percentage. -300.00 ... 300.00%
5.0 s / real32 Defines the time period for the first step of cleaning
cycle. First step time 81.22
10 = 1 s / 10 = 1 s First step time in second. 0.0 ... 6500.0 s
5.0 s / real32 Defines the time period for the pause after each step.
The speed reference will be zero during Off time. Off time 81.23
10 = 1 s / 1 = 1 s Off time in seconds. 0.0 ... 6500.0 s
10.00% / real32 Defines speed reference for the second step of cleaning
cycle.
Note that the parameter
75.15 Starting speed setting
is also taken into use for the cleaning operation.
Second step
reference 81.24
10 = 1% / 100 = 1% Second step reference in percentage. -300.00 ... 300.00%
5.0 s / real32 Defines the time period for the second step of cleaning
cycle. Second step time 81.25
10 = 1 s / 10 = 1 s Second step time in seconds. 0.0 ... 6500.0 s
20.00 s / real32 Defines acceleration time for the cleaning operation. Cleaning acc time 81.31
1 = 1 s / 100 = 1 s Cleaning acceleration time in seconds. 0.00 ... 30000.00 s
20.00 s / real32 Defines deceleration time for the cleaning operation. Cleaning dec time 81.32
