Troubleshooting

Error type
The controller/dosing equipment will
not start
Steady/low flow in fittings
Not possible to calibrate the unit.
High and low values during operation
- unstable calibration value.
15. Changing the system settings

Time-Out - exceeded dosing time

Time-Out is factory installed, a built-in security soft function. It sets
a limitation for continuous dosing time when closes dosing and
starts the alarm after 90 minutes of uninterrupted dosing.
This is done to prevent excessive dosing, which may occur,
for example, due to leakage or measurement error.
If dosing equipment needs more than 90 minutes of dosing to achieve the
accurate values, Time-Out function can be deactivated, see below.
NOTE! If Time-Out is disabled for a long time, unlimited amounts of chemicals will be dosed into the pool or leak out into the
engine room in case of error. Always check hoses, connections and chemical levels regularly and make sure Time-Out is
activated.
How to check the device settings: (turn off power, wait for around 3 sec.), turn on power to the unit. In appr. 2 seconds, the start-
up sequence will start again, LEDs ( 1-7 ) will light in a sequence, set mode will be displayed as LED blinking.
Time-Out activation (only chlorine unit )
1. Turn off power to Mini Master.
2. Turn on power.
3. Press H button when LED 1 goes up, release when LED 2 goes up (every LED blinks 2 times/sec.).
4. Press H button when LED 6 goes up, release when LED 7 goes up.
5. When the start-up sequence is complete, set mode is confirmed by blinking LEDs (3, 4 and 6).
6. To activate the Time-Out function again, repeat steps from step 1. When the start-up sequence is
complete, set mode is confirmed by blinking LEDs (3, 4 and 5).
Action
• If the controller is being blocked over a closed circulation pump, the unit will not
start
Check/clean prefilter. Check valves and hoses for measured water
• Low/high measured water flow (only chlorine unit)
- check filter/measured water flow.
• Make sure that the pool remains within recommended water values.
See section 3 "Water chemistry".
• Unreasonable measurement values; free chlorine values <0.3ppm resp. >3.0ppm
- Check chlorine level with photometric instruments.
• High cyanuric acid level in the pool water
- check with photometric instruments Dilute pool water with tap water or increase
the set value for free chlorine.
• Electrode- or connection fault
- check connections, clean the electrodes or replace them.
See section 16 "Electric diagnostics".
• Too high or too low set flow dosing values. Adjust dosing based on pool volume
and turnaround rates.
• Check that the water flows evenly through the fittings.
• Check electrodes and connections condition.
• Check that there is negative pressure in the measuring cells/fittings,
see Section 8 "Start-up", par. 5.
• Make sure that the pool remains within recommended water values.
See section 3 "Water chemistry".
