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 uidity 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 ow 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 deection (10–180 pulses/min).
d. Current output control: maximum deection (20mA).
(CO2 dosing equipment requires on/off or pulse width control).
Control is programmed in conguration mode.
Acid dosing or alkali dosing On/Off is programmed in conguration 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 deection (10–180 pulses/min).
d. Current output control: maximum deection (20mA).
Control is programmed in conguration mode.
1–3 current outputs (free chlorine, redox, combined chlorine and pH) 0–20 mA or 4–20 mA are programmed in conguration
mode (individually for each channel). Current outputs normally follow the measurement value, but can also be congured so that
the control value is followed thereby allowing current output control.

Separate high and low alarms (limits can be set) are indicated via ashing alarm LED(s) and a common alarm relay.
The alarm is shown as “Lo” or “Hi” on display 1–3 while the Reset button [15] is held depressed.
pH value outside of limit values stops chlorine dosing. This is indicated by a ashing AUTO LED on the chlorine channels and
the alarm text “PHF”. Chlorine dosing is stopped until the pH value has returned to a permitted value.
Flow alarm (PNP potential-free connector/turbine sensor that can be deactivated in conguration mode) is indicated via alarm
LED and alarm relay in alarm mode. The registered alarm is also shown as “FLo” on display 1–3 while the Reset button [15] is
held depressed. There is no automatic dosing during stop in ow.
All alarms have a 5-second delay, except for ow alarm, high alarm and low alarm. For the high and low alarms, delay can be
set (in Setup) between 5 and 600 seconds. The ow alarm delay can be set (in Setup) between 0 and 30 minutes.
Alarm for dosing error can be selected in conguration mode (time in minutes > 0).
Dosing error is indicated (if dosing time is selected in conguration mode) via ashing alarm LED(s) and a common alarm relay.
The alarm is shown as “doS” on display 1–3 while the Reset button [15] is held depressed.
Dosing is stopped until the alarm is reset. The dosing time counter is always zeroed with a reset.
A dosing error alarm is generated in the following conditions
• On/Off dosing, Pulse width dosing, Frequency dosing, Control output-controlled dosing :
An alarm is triggered if dosing is continual for a longer time than the specied max. time in minutes (1-60 as specied in con-
guration mode). An alarm is also triggered if manual dosing is too long.

6. Safety
To prevent direct contact between the chemicals, separate the chlorine dosing point and the acid/alkali dosing point with at least
500 mm, always ACID BEFORE CHLORINE, refering to the installation example on pages 8–9.
Lock the dosing pumps to the circulation pump using the motor guard or the ow switch.
For best results, use a photometer during calibration.
Proper installation and care is required to prevent invalidation of the warranty.
“Persons (including children) with limited physical or mental capabilities must not use the device without instructions on how to
use it in a safe manner,” as per IEC 60335-1.
7. Installation
General
The system can be installed at any time point without consideration to the life span of the electrodes as these are delivered
separately and can even be delivered at a later point in time.
Install Autodos M at a dry and vibration-free location, against rm, at support and accessible for support and reading.
The display must be well visible and the buttons easily accessible.
The ow cell should be positioned as close to the monitoring point as possible to prevent unnecessarily long response times.
Note the direction of ow.
Check that the electrode kit complies to your Autodos M unit, see point 2 page 12.
If the position of the Autodos puts it at risk of freezing, the ow cell modules must be emptied of all water and the electrodes
must be stored frost-free standing in water (save the electrode packaging for this purpose).
Note! When installing Autodos M with free chlorine electrode in pools where organic chlorine was previously used,
all water must be drained and replaced with new water.This because the cyanuric acid content in the pool water from orga-
nic chlorine (Trichlor or Dichlor) produces a signicantly higher chlorine value in a DPD no. 1 test. This makes correct calibration
impossible.
Installation, pipes
The outlet from the ow cell should be kept free from pressure, e.g. by leading outlet water to an equalization tank or a drain.
For installations in which the ow cell outlet cannot be routed without pressure to a drain or equalization tank, the measurement
water should be sampled after the lter and the return of the pump suction line.
Connections only need to be tightened by hand.
Monitoring and dosing points are most easily made with saddle clamps.
In order to prevent air from being mixed in with the measurement water (which could affect the measurement value), the
measurement connection on the pipes should not sit at the highest point.
