14. Operation information and troubleshooting
LED signals
Type of LED signal
The two red LEDs come on with a steady light
The two red LEDs flash alternately
All red and yellow LEDs flash at the same
time
LED comes on with a steady light
lit for a long period - out for a shorter period
Flashing LED,
lit for a short period - out for a longer
period
Rolling LEDs
Chlorine unit only:
Flashing LEDs 3, 4, 5 after start sequence
Flashing LEDs 3, 4, 6 after start sequence
pH unit only:
Flashing LEDs 2, 4, 5 after start sequence
Flashing LEDs 2, 4, 6 after start sequence
Troubleshooting
Type of fault
Unit does not start
Unstable/low flow in the fitting
The unit cannot be calibrated
High and low values during operation
- calibrated value not stable.
Underpressure in return hose
Reservations
We accept no liability for printing errors. We reserve the right to make changes to MiniMaster technical specifications or its manual.
Colour differences may occur due to technical factors in the printing process.
Explanation
The unit is not calibrated - dosing is not possible
Flow too high or too low – dosing shut off
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.
Dosing is activated, metering in progress
Dosing is not activated, but metering is in progress
Forced dosing in progress
Time-Out activated = dosing blocked after 90 minutes of continuous dosing,
(factory set value)
Time-Out deactivated (unlimited continuous dosing)
Alkali dosing activated
Acid dosing activated
Action
1. If the unit is interlocked over a shut down circulation pump, the unit will not
start.
2. Check fuses on the circuit board.
Check/clean the pre-filter Clean and lubricate the adjuster screw on the fitting.
1. Low/high measurement water flow (chlorine unit only) - check filter.
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.
Dosing set too high or too low. Adjust dosing based on pool volume and
circulation speed.
Check that the water flow through the fitting is even.
Check the condition and connections of the electrodes.
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 flow using ball
valve L2 (see Figure 1) carefully until the green LED (flow OK) comes on.
