concentrate
Commissioning must be done by certified service persons.
Wear personal protective equipment.
Observe the chemical manufacturer's safety data sheets
(SDS) and safety instructions of the used chemicals.
Make sure that all electrical, hydraulic and mechanical
installation is done correctly and all system components
are ready for operation. The system must be stopped and
control mode must be "Local".
Some pre-assembled mechanical and hydraulic
connections in the system are loosened for transport.
Make sure all connections are tightened before
commissioning.
Do not step on the system. The system is not designed to
carry the weight of a person.
Make sure that the liquid-concentrate line is connected
with a foot valve and installed with flooded suction to
avoid dry-running of the pump.
Initial startup
After switching on the main switch, the PLC and the touch panel
perform a self test.
After approximately 40 seconds the menu System overview is
displayed.
An alarm that indicates wrong input values is displayed, because
the system is not yet correctly parametrised and
commissioned. Acknowledge the alarm after commissioning.
