3.2 Operating parameters
When the control system is switched on, the following four operating modes exist:
STOP
The control system does not carry out any production process. All outputs remain inactive.
Failures are not registered.
OPERATION
The control system fulfills the production in accordance with the respective operating conditions
in the unit. As long as the unit status is DISPOSAL, PRODUCTION ON, CONCENTRATE
DISPLACEMENT/FLUSH or DISCONTINUOUS RINSE, the current operating data
(conductivity, temperature, etc.) are displayed one after the other (rolling). Failures are
registered, processed and displayed.
DISINFECTION
The control system does not carry out any production process, but INLET VALVE, OUTLET
VALVE as well as the PUMP are switched on so that a disinfection can be carried out. No
failures are registered.
DIAGNOSIS
The DIAGNOSIS is called via the main menue (see item 4.4.1). For diagnosis purposes, all
control outputs can be manipulated via the keyboard and the input status (analog/digital) can be
displayed (see item 4.4.5).
Attention: Failures are not registered/displayed.
The current operating mode is maintained when the system is switched off, that means the
control system will be in the same operating mode which was running when the system was
switched off.
