Xylem IM043 AQUAVAR Variable Speed Pump Control - Manual (Page 62)

Test Run
The AQUAVAR controller can carry out a test run of the pump either automatically or manually. For
automatic settings, enter the number of hours you want to elapse between the last pump shut
down and the test. Possible settings are between 10 and 100 hours. When the time has elapsed,
the pump will automatically turn on at 50% of maximum frequency (normally 30 hz) for 20
seconds and then turn off again.
Submenu Test Run Manual
To conduct a manual test run of the pump, enter this submenu by holding down on the S key. The
first display in the submenu is the activation display for the test run. To start the test, press the up
and down arrow keys at the same time. If you want the test to be conducted at some other
frequency than 30 hz, use the next display in the submenu: Test Frequency. This can be set
from 6-60 hz. The final display in this submenu is Boost Test-Run. This allows you to set a start-
ing voltage boost to ensure proper starting of the motor at the frequency you have selected. This
should be left at the pre-set 5% setting to avoid motor overload. When finished, hold down on the
S button until the display returns to the Submenu display.
Submenu Errors
Two of the functions in this submenu have been covered: Conveyor Limit (used to set system shut
off when maximum flow is exceeded) and Delay Time (used to set pump shut off in conjunction with
conveyor limit and a suction side pressure switch or float). The remaining displays in this submenu
are used to show the cause of failure in the last three instances where a pump or system failure
caused the AQUAVAR controller to turn the pump off.
Within the Error Submenu, the Error Reset display allows the operator to tell the AQUAVAR
controller to re-try pumping after a non-fatal fault. When turned on, the AQUAVAR controller will
retry up to five times before shutting the unit off. If Error Reset is off, the AQUAVAR controller will
shut down the system the first time a fault occurs. In both cases, the AQUAVAR controller can be
reset by removing all power to the unit for at least one minute. This will reset the fault counter to
zero.
Clear Errors
This display allows you to clear all error memory by entering a password. To clear error memory,
enter 0726, then press “ “ in the clear errors screen once. “Cleared” should appear.

This will only work when the Auto Start function on the main menu is on. If you do not want
to use the automatic test run function, you can turn it off by selecting 100 hours, and then
pressing the up and down arrows at the same time until the display changes to deactivated.
