Commissioning / recommissioning
Please also generally observe the operating instructions for the accessories not described in
these instructions.
•
The control system is installed in a dry, frost-proof and flood-proof area.
•
The connections are carried out in accordance with the associated wiring diagram.
•
The on-site pre-fusing meets the specifications of the respective associated wiring
diagram.
•
The power supply corresponds to the requirements stated in the respective associated
wiring diagram. If necessary, the control transformer connection must be adapted to the
local conditions (input voltage ± 5%).
•
Before the mains voltage is switched on, you must make sure that there will not be an
unintended start-up of the system.
•
Only then turn on the mains voltage!
•
Set the parameters to your requirements.
•
Finally carry out a function test.
14.
Decommissioning
You must ensure during the decommissioning of the system that no unintentional
consequential losses occur (i.e. like an accidental overflow, etc.). When working on the control
system and/or components of the control system, the 5 safety rules of electrical engineering,
among others, must be observed.
1. Disconnecting (turning off the power supply)
2. Secure against restart.
3. Testing for zero-potential (use the appropriate instrument).
4. Earthing and short-circuiting.
5. Covering adjacent live parts (potential-free contacts can carry external
voltage).
When working on the pump and/or the measuring system, or on the entire system for that
matter, the possibility of an unintentional pump start-up must be prohibited.
It is important to note that when working on the control system, or even
on the system as a whole, you must prevent personnel hazards.
15.
Servicing
We recommend checking the control system and all its accessory parts (or also the complete
system) at regular intervals, depending on application and environmental influences.
•
Visual inspection of the system and the removal of any contaminants.
•
Visual inspection of the system and replacement of any damaged components.
•
Perform an operational check.
•
Inspect measuring systems.
•
Batteries must be changed no later than every 5 years.
