12.1.1 Feedwater conductivity:
A single press on the menu-key allows the feedwater conductivity to be read and the limit-
ing value of the feedwater conductivity to be set. The fault message that flashes in the
fourth line of the display when the feedwater limiting value is exceeded is
"Limit value

12.1.2 Ultra pure water limiting value:
Two presses on the menu-key in this menu allow the fault display for the pure water limit-
ing value and the pure water limiting value to be set. As soon as the fault display is
switched on, the fault will be displayed both in Stand-by mode and in Production mode.
When the fault display is switched off, the fault is only displayed in Production mode.
The “Lim. val.pure w.” message is displayed when the limiting value is exceeded.
