Examples of reservoir shapes and levels
Following are examples of different reservoir shapes and
levels required.
Fig. 65 With a uniform shape, only one level /area is required
as the area is the same.
Fig. 66 With this shape, 4 levels and areas are required.
5.5.6
Overflow level switch
runtime
If there is an overflow level switch connected to digital in on
either Master or Follower unit (not to mix up with “[3A21]
Overflow” level) consider changing the minimum run time
in menu “[3A14] RnTimeOFsw” when switch is activated.
Default is 0 minutes implying only run when activated.
[3A14] RunTimeOFsw
Number of minutes to run after overflow switch is activated.
5.6
Copy to follower
In case of a Master and Follower system it is now time to
copy parameters to the follower. On a “Standalone” system
skip this part.
Navigate to menu “[21F] CopyToFlw” or press the toggle
button.
1. Make sure the drives are in stopped mode.
2. Set to “Copy” and press Enter.
3. Verify that “Done” emerge after a while.
5.7
Test run
Now the configuration is finished; time to test that
everything works as expected.
Sump level
Sump level is shown in menu “[7411] Sump level” (and by
default as first row in [100] menu).
Navigate to menu “[7411] Sump level” or press toggle
button and make sure the current sump water level
displayed corresponds to actual level in the sump.
Auto/Off/Manual switches
Make sure the external Auto/Off/Manual switches are set in
correct position and connected correctly as described in
chapter 4.3 page 29.
1. Set both switches in “Off” position.
2. Go to menu “[746] Pump mode” on the Master AC
drive. In this menu the mode for the switches are shown.
3. Make sure “Off” is shown for both switches in this
menu.
In case not “Off” is shown for both switches, make sure
the switches are in correct position and connected
correctly. Also inspect the configuration in menu “[52X]
DigIn X” where X is the digital input number.
4. Turn the Auto/Off/Manual switch to Manual for one of
the pumps. The corresponding pump should start and
“[746] Pump mode” should change to “Manual” for the
corresponding pump (the other pump should stay in
“Off” state). Test both pumps. Switch both switches
back to “Off”
.
5. Change both switches to Auto.
6. “[746] Pump mode” should change to “Auto” mode
.
Verify “Auto mode” operation
In “Auto” pump mode the pump should start when “[7411]
Sump level” has reached "[7412] ActStartLvl” (that should
be same as configured “[3A22] Start level" unless “[3B2]
Start lvl Δ” is configured). Monitor how the pump decreases
the level and eventually comes to a stop when “[7411] Sump
level” goes below “[3A23] Stop level”.
