10.7.14 Forced pump changeover (4.2.4)
Fig. 40
Forced pump changeover
Description
This function ensures that the pumps run for the same number of
operating hours. In certain applications the requirement remains
constant for long periods and does not require all pumps to run.
In such situations, pump changeover does not take place
naturally, and forced pump changeover may thus be required.
Once every 24 hours the controller checks if any pump running
has a larger number of operating hours than pumps that are
stopped. If this is the case, the pump is stopped and replaced by
a pump with a lower number of operating hours.
Setting range
The function can be activated/deactivated. The hour of the day at
which the changeover is to take place can be set.

10.7.15 Test run (4.2.5)
Fig. 41
Test run
Description
This function is primarily used in situations where the forced
pump changeover is deactivated, and/or if the Hydro MPC is set
to operating mode
Stop , for instance in a period when the system
is not needed. In such situations, its important to test the pumps
regularly. The function ensures that
• 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.
Each pump is connected to a counter.
The pump starts automatically one by one and runs for 5
seconds.
Note:
Pumps in Manual operating mode are not included in the
test run. If there is an alarm, the test run will not be carried out.
Setting range
• Not used
• Once every 24 hours.
• Once every 48 hours.
• Once a week.
