3.2.14 Circuit Layout
3.3 Alarms
The sistem is equipped with the following alarm:
Low level alarm, with 5 seconds of Hysteresys. Low level alarm pH stops the
♦
dosing of pH pump only (the same for Rx).
Flow alarm, with 5 seconds of Hysteresys. Flow alarm stops the dosing of both the
♦
pumps (with Flow alarm on the Relè is always open).
Dosing alarm (see also 3.2.5). Dosing of product without effect (withou variation of
♦
pH&Rx readings). Dosing alarms can be removed only with system restart (use
ON/OFF switch)
Measure alarm: the system is equipped with an adding alarm of pH reading, if the
♦
reading of pH is lower than 5 or higher than 9 (WARNING), the system stops the
pumps. If the reading of pH is lower than 5 or higher than 9 it is recommended to
check the probe and the water.
4.0 Electrode winter break
Remove the electrodes during winter break. Fill in the protection cap with 1/3 of water and
put it on the electrodes.
§ It's recommended to install new electrodes every season begin §
5.0 Coming season start-up procedures
- It's recommended to install a new electrode when season begin, in order to prevent
failure during season.
- After the electrode replacement or start up of the apparatus, repeat the calibration
procedure.
