    Electrical connections can be made as suggested in the following diagrams and should be carried out by a qualified electrician. When installing an AUTODOS 5000 with free chlorine electrode in swimming pools that have previously been treated with organic chlorine (trichlor or dichlor), the pool water must be changed. This is because the cyanuric acid content in the pool water, caused by the organic chlorine, results in an exceptionally high value of chlorine when DPD1-testing, thus making a correct calibration impossible.

Note that the alarm relay is called during normal operation and is released (voltage free) if a fault condition occurs. After a RESET the alarm relay is always reset (voltage applied) and the 'ALARM' LED is either cleared or goes over to a steady display, depending upon whether or not the fault condition still exists.

    AUTODOS 5000 - 2005-01-21 4. General Description of Pool Water Cleaning AUTODOS 5000 automatically monitors and controls the condition of swimming pool water maintaining the chlorine and pH levels to desirable set values. For effective bacterial control and sanitation of pool water it is essential to maintain the correct level of free chlorine, but free chlorine readily combines with bather contaminants such as perspiration, cosmetics, hair lotions etc.

Wanted Regulation Result The figure above is taken from the Swedish 'Naturvårdsverket allmänna råd 88:1, bassängbad - vattenkvalitet och kontroll'. 4.2. pH Regulation As previously stated the pH value of pool water is a measure of its acid/alkaline balance (pH is actually a logarithmic measure of free hydrogen ions).

    0.60 mg/l and 1.00 mg/l in bubble pools (dependent upon the pH value). When installation of an AUTODOS 5000 with free chlorine electrode in swimming pools, that have previously been treated with organic chlorine (trichlor or dichlor), the pool water must be changed. This is because the cyanuric acid content in the pool water, caused by the organic chlorine, results in an exceptionally high value of chlorine when DPD no.1-testing, thus making a correct calibration impossible.

  • Page 29: General Description

    AUTODOS 5000 is designed to control swimming pool water conditions. It is equipped with 3 independent channels for monitoring chlorine (free and combined) and pH. AUTODOS 5000 can regulate pH (by acid or alkali dosing) and chlorine levels. Regulation of chlorine is done by lowering the total chlorine level and raising the content of free chlorine.
  • Page 30 FREQUENCY - MAN. Alarm is activated after dosing for a period longer than the specified maximum dosing time (1-60 minutes). The AUTODOS 5000 is equipped with three current outputs, selectable (in set-up) 0-20 mA or 4-20 mA. Normally the outputs monitor the value for channel 1-3, but can also be set up as regulation signal.
