LED signals
Type of LED signal Explanation
The two red LEDs come on with a steady light The unit is not calibrated - dosing is not possible
The two red LEDs ash alternately Flow too high or too low – dosing shut off
All red and yellow LEDs ash at the same
time
Time-Out function:
Dosing has taken place continuously for 90 mins – dosing shut off.
- Check dosing pump function and setting.
- Check that the chemical level in the drums is not too low.
- Check leakage/function of the dosing hoses, dosing points and dosing pumps.
- If the installation has a salt chlorinator: Check that the salt chlorinator is not
shut off, that it is correctly set and that the signal cable between the chlori-
nator and the MiniMaster is correctly connected.
Restart: First shut off the dosing (On/Off button E), wait a few seconds,
then start dosing by pressing the On/Off button (E) again.
LED comes on with a steady light
lit for a long period - out for a shorter period
Dosing is activated, metering in progress
Flashing LED,
lit for a short period - out for a longer
period
Dosing is not activated, but metering is in progress
Rolling LEDs Forced dosing in progress
Chlorine unit only:
Flashing LEDs 3, 4, 5 after start sequence Time-Out activated = dosing blocked after 90 minutes of continuous dosing,
(factory set value)
Flashing LEDs 3, 4, 6 after start sequence Time-Out deactivated (unlimited continuous dosing)
pH unit only:
Flashing LEDs 2, 4, 5 after start sequence Alkali dosing activated
Flashing LEDs 2, 4, 6 after start sequence Acid dosing activated
Troubleshooting
Type of fault Action
Unit does not start 1. If the unit is interlocked over a shut down circulation pump, the unit will not
start.
2. Check fuses on the circuit board.
Unstable/low ow in the tting Check/clean the pre-lter Clean and lubricate the adjuster screw on the tting.
The unit cannot be calibrated 1. Low/high measurement water ow (chlorine unit only) - check lter.
2. Unreasonable measurement values;
free chlorine values < 0.3 ppm and > 3.0 ppm
- check the chlorine values using photometric equipment
3. High levels of cyanuric acid in the pool water - check using photometric
equipment.
Dilute the pool water with tap water if necessary.
4. Electrode or connection fault - check connections, clean electrodes or
replace them.
High and low values during operation
- calibrated value not stable.
Dosing set too high or too low. Adjust dosing based on pool volume and
circulation speed.
Check that the water ow through the tting is even.
Check the condition and connections of the electrodes.
Underpressure in return hose Press the Flow button (F, see Figure 6), open the Adjuster Screw (H, see
Figure 7) until the red LED (High) comes on. Then cut the ow using ball
valve L2 (see Figure 1) carefully until the green LED (ow OK) comes on.
