8.7.18 Pump test run (4.2.5)
Fig. 57
Pump test run
Description
The function is primarily used in situations where the forced pump
changeover is disabled, and/or if the system is set to operating
mode "Stop", for instance in a period when the system is not
needed. In such situations, it is important to test the pumps
regularly.
Advantages of this function:
• Pumps do not seize up during a long standstill due to deposits
from the pumped liquid.
• The pumped liquid does not decay in the pump.
• Trapped air is removed from the pump.
The pumps start automatically one by one and run for 5 seconds.
Setting range
• Time of day
• Day of week
• Include pilot pump.
Setting via the operating panel
• Settings > Pump cascade control > Pump test run.
1. Select interval.
2. Set:
• Time of day
• Minutes.
3. Select the day of week if you select "Once a week".
4. If the system is configured with a pilot or a backup pump,
select "Include pilot pump".
Factory setting
The function is disabled.
8.7.19 Pump stop attempt (4.2.7)
Fig. 58
Pump stop attempt
Description
The function allows you to set automatic stop attempts of a pump
when several pumps are running. It ensures that the optimum
number of pumps is always running, in terms of energy
consumption. See section
8.7.20 Pump start and stop speed
. At the same time, the purpose is to avoid disturbances in
connection with automatic stop of pumps.
Stop attempts can either take place with a fixed interval set under
"Interval between stop attempts" or by self-learning. If self-
learning is selected, the interval between stop attempts will be
increased if repeated attempts to stop the pump fail.
Setting via the operating panel
• Settings > Pump cascade control > Pump stop attempt.
1. Select: Self-learning or Fixed interval.
2. Set "Interval between stop attempts" if you select "Fixed
interval".
3. Select: Enabled.
Factory setting
The function is enabled, and "Self-learning" is selected.
Pumps in operating mode "Manual" are not included
in the test run. If there is an alarm, the test run will
not be carried out.
