Changing Dosing Settings For Acid Or Base (Ph Unit ); Disclaimer - Pahlen MiniMaster User Manual

MiniMaster
Changing acid or base (pH unit ) dosing settings
The pH dosing function - pH content lowering agents (acid) is factory set in pH unit.
When power is supplied to Mini Master, the start-up sequence begins in appr. 2 seconds, and LEDs 1–7 sequence lights up.
You can see the set mode.
If you want to increase pH dosing base, make the following adjustment.
NOTE! This applies only to pH unit, and pH calibration must be done before the change starts.
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.
Conversion to Alcali dosing (only pH 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 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 (2, 4 and 5).
While isplay is active, press and hold H button for at least 5 seconds until LED blinks fast.
The setting is now blocked.
6. To change acid dosing setting, repeat steps from step 1. When the start-up sequence is complete, set mode is confirmed by
blinking LEDs (2, 4 and 6) = acid dosing activated.
16. Electric diagnostics
At troubleshooting in electrodes and calibration.
1 Put control unit into a standby mode - LED flashes
Press K button and hold it pressed.
2
LEDs 1–7 goe up simultaneously.
LEDs correspond to electrode signal strength (see section 11 "Operation - LED display measured values"),
in which LEDs 1–4 correspond to pH 7.3, respective free chlorine 1.0 ppm.
3
The signal should comply with measured photometric value. In case of deviation see Section 14 "Troubleshooting".
