1. General information about the measuring equipment
Autodos M is an equipment intended for measurements and dosage of chemicals in swimming pools. The apparatus is equipped
with 1-3 channels (depending on model) to measure levels of chlorine (free chlorine and bound chlorine), redox and pH.
This manual covers all combinations. Please read the whole manual to get a full picture of how the system works and all its
setting possibilities.
Autodos M is delivered in two different parts: one measuring and control unit Autodos and one complete electrode kit.
•
Autodos:
include a measuring- and control unit, connectors, and this systems manual. The control unit is pre-
programmed with factory settings for each respective model, but individual changes are possible to make by the user.
It is also possible to enter different access codes to avoid accidental changes.
•
Electrode kit:
include electrodes (different electrode types depending on which measurements and results you wish to
present), calibration liquids, connectors for the electrodes, and manual for the electrodes.
Autodos M´s properties
• Measures and controls pH (base or acid dosage) and chlorine in the forms of redox, free chlorine and bound chlorine.
With regards to bound chlorine, the total level of chlorine is measured and the display shows the value for bound chlorine.
This is calculated by Total chlorine – Free chlorine = Bound chlorine.
• Autodos uses two point calibration for each measuring cannel to ensure optimal measurements.
• Has a separate galvanic part for each electrode entry point.
•
Warns for fluidity errors in the valve, dosage errors and measurement values outside preset boundaries.
• Continuously shows the pool water’s current pH-value, free chlorine, bound cholrine and redox in clear LED-displays.
By pressing different buttons, the displays can also be made to show other values, for example flow and temperature.
pH-regulator
pH adjustment can be used according to:
•
Manuel off.
•
Automatic regulation against set value as per:
a. On/off control*.
b. Pulse width control
c. Frequency control
P, PD, PI or PID regulator 10–180 pulses/min.
d. Current output control
P, PD, PI or PID regulator 4–20 or 0–20mA.
•
Manuel dosing:
a. On/off control*:
dosing relay pH always On.
b. Pulse width control:
dosing relay always On.
c. Frequency control:
maximum deflection (10–180 pulses/min).
d. Current output control:
maximum deflection (20mA).

dosing equipment requires on/off or pulse width control).
Control is programmed in configuration mode.
Acid dosing or alkali dosing On/Off is programmed in configuration mode.
Chlorine regulator
Free and combined chlorine works the same and can be used according to:
•
Manuel off.
•
Automatic regulation against set value:
a. On/off control*.
b. Pulse width control
c. Frequency control
P, PD, PI or PID regulator 10–180 pulses/min.
d. Current output control
P, PD, PI or PID regulator 4–20 or 0–20mA.
•
Manuel chlorine dosing:
a. On/off control*:
dosing relay chlorine always On.
b. Pulse width control:
dosing relay always On.
c. Frequency control:
maximum deflection (10–180 pulses/min).
d. Current output control:
maximum deflection (20mA).
Control is programmed in configuration mode.
1–3 current outputs (free chlorine, redox, combined chlorine and pH) 0–20 mA or 4–20 mA are programmed in configuration
mode (individually for each channel). Current outputs normally follow the measurement value, but can also be configured so that
the control value is followed thereby allowing current output control.
