User interface

The user interface of the RO 1000 consists of a text display (16x2 characters), a keyboard
covered with a protective film (6 keys) and 7 indicator lights.
4.1.1 Indicator lights
The indicator lights correspond to the most important operating conditions of the unit.
The control system has the following indicator lights:
OPERATION
Active, if the control system is in the operating mode OPERATION and if at least one pump is
switched on. This indicator light will be a flashing light (instead of a continous light) if the set
maintenance interval has run out.
FAILURE
Active, if there is an operating trouble. In this case, the reason is displayed. In case of Cy alarm
the failure LED flashes. Should the trouble light flash immediately after having the control system
switched on, the reason is an internal system failure (see item 3.5).
DISINFECTION
Active, if the control system is in the operating mode DISINFECTION.
DISPOSAL
Active, if the control system is in the operating condition DISPOSAL.
FORCED STOP
Active, if the FORCED STOP input is activated and if the control system is in the operating
mode OPERATION.
TANK FULL
Active, if the TANK FULL input is activated.
4.1.2 Keyboard
The control system has keys for the functions UP
as well as ESC (on the equipment keyboard, symbols/arrows are used to identify some of
them). They allow to call via the menu all functions and to modify the system settings/
parameters.
4.1.3 Text display
The purpose of the LC text display is to indicate, besides the indicator lights, the current
operating mode or the current unit condition respectively (normal level); it also serves for the
(menu-assisted) user communication for control system settings (user/technician level).
