4. Operation of the Control System
The operation of the system is carried out via a microprocessor in the control unit. The microprocessor
allows for the set-up of operating parameters, the display of operating conditions and the query of system
parameters as well as the programming of working times through a specialist company.
Adjustments are made by scrolling through numerical values using the two arrow keys . The set-
tings are then confirmed by pressing the button.
The individual dialogues can be terminated ahead of time by pressing or will be terminated automati-
cally after 2 minutes.
The control system is broken down into the following display pages:
1. Basic level: Status of the cycle sequence with the elapsing remaining time, as well as the display of
error messages.
2. Operator level: The operator can access the operator level by pressing the button and enter oper-
ator-specific settings.
3. Service level: A password-protected service level can be accessed from the operator level using an
additional code. This level is reserved for trained personnel. Here adjustments or changes can be
made and diagnostic data is retrieved.
4.1 Control Programme
The control system switches the outputs for air compressors and stepper motors on a timer.
The timing is determined by the set sequence tables. A complete cleaning cycle is started for each start
time in accordance with the selected sequence table.
By setting up holiday times in the operator level, the complete sequence of cleaning cycles can be sup-
pressed for the set period of time. Only one holiday cycle with greatly reduced activity takes place at this
time. During this time, no treated wastewater will be removed, as there should be no supply.
