4.5 Execute test run
Requirements:
■
The ball valve and/or gate valve is opened in the pressure pipe.
■
The control is connected to the power supply.
During the trial run, pay attention to the following:
■
Perform the trial run at least twice during commissioning.
■
Perform the trial run with drinking water, rainwater or process water (if it meets the
local discharge conditions for effluent).
■
Avoid dry running during the trial run.
■
Observe the signals/messages in the display panel of the control.
IMPORTANT
■
If knocking noises/vibrations occur in the pressure pipe when the pump is switched off,
set an after-running period or increase the set after-running time.
■
If SITA pumps are used, the ATEX mode must be activated in the control menu. If the
level sensing does not determine any liquid, the pumps cannot be started. This applies
to the manual function, and to 24h operation and the telecontrol systems.
