Faults detected during operation trigger the fault indicator (red LED) and<br />
a corresponding event message appears on the display. The <strong>Condair</strong> <strong>Dual</strong><br />
makes a distinction between alarms and errors.<br />
Alarms<br />
An alarm indicates a temporary fault that was detected during operation<br />
(short-time interruption of the water supply) or faults that do not cause<br />
damage to the system. If the source of trouble disappears within 30<br />
minutes, the alarm is reset automatically. Otherwise, the system issues<br />
a corresponding error message.<br />
Indication: red LED flashes (once a second)<br />
alarm message appears on the display<br />
Example:<br />
Alarm message Cause/Remedy<br />
alarm 10<br />
Ag ion current<br />
alarm 09<br />
permeate temp.<br />
Cause: Permeate conductance (limit) required for stopping permeate flushing<br />
is not reached even after extended flushing.<br />
Remedy: Check reverse osmosis system.<br />
Cause: Pressure at fully demineralized water connector of booster pump is too<br />
low (cause: water conduit too narrow, reverse osmosis system too<br />
small or too many consuming devices connected to reverse osmosis<br />
system).<br />
Remedy: Check reverse osmosis system and fully demineralized water supply<br />
conduit. Pressure at fully demineralized water connector must be at<br />
least 2 bar (working pressure). Install larger supply conduits (min.<br />
inner ø 15 mm).<br />
This message appears only if the system is equipped with built-in booster pump!<br />
Cause: Admissible maximum pressure of permeate exceeded.<br />
Remedy: Check reverse osmosis system and/or setting of booster pump. Integrate<br />
a pressure regulator into the supply line.<br />
Cause: Operating temperature of booster pump is too high or flat ribbon cable<br />
between power supply PCB and CPU PCB (inside the control unit) is<br />
disconnected or defective.<br />
Remedy: Check booster pump. Plug in flat ribbon cable or replace cable, as<br />
required.<br />
Reduce temperature of fully demineralized water supply (max. 45 °C).<br />
Cause: Nominal value of ionization current not reached (cable defective or<br />
disconnected, silver electrodes worn).<br />
Remedy: Check/Re-establish electrical connection of silver ionization. Replace<br />
silver ionization cartridge (see chapter 6.4).<br />
