the chlorination process would last too long decrease the time base
gradually until a conditioning time of approx. 30-45 minutes
● P12 alarm pump 2 = 60 minutes
Common Settings for the Two Examples Described Above:
● P13 start-up delay of 15 minutes (average time required for the polarization
of ORP electrodes)
● P16 protection PASSWORD to prevent unauthorized access
Errors / Alarms
Every error or anomaly detected by the system generates an alarm message on the
display:
● LEV1 / LEV2: The level sensor 1 or 2 detected a low level of the liquid to be
dosed; restore the level into the related tank.
● FLOW: The flow sensor detected an anomaly that can be due to low pressure
in the hydraulic circuit or wrong adjustment of the flow sensor in the
electrode-holder; restore the flow or adjust the sensor.
● STOP: This message indicates that the pumps have been manually
de-activated by pressing the ON/OFF button.
● UR / OR: Under/Over Range: measurement out of range; this signal can be
generated by a dead or broken electrode or by a damaged or disconnected
cable; check the system and restore correct measurement conditions.
● AL.1 / AL.2: Dosing time alarm for pump 1 or 2: measurement is outside the
set-point for a time longer than the set limit due to an insufficient dosage or a
wrong configuration of the alarm time (see parameters P11 and P12); set the
parameters properly.
● Calibration Impossible: Check the status of the electrode and connection
cable; check that the calibration solutions are not expired or contaminated;
repeat the procedure.
