ERRORS / ALARMS
When an error or alarm occurs, the display shows the related warning message on the fourth line. If more
than one error / alarm is active, is shown the sequence of all warning messages. If you have set the
displaying of the telephone number (or message) when an error occurs (P33 ≠ 0), the number to contact
for technical assistance appears on the third line of the display.
Messages that can appear on the fourth line of the display, are listed here below:
No alarm Everything is functioning properly!
Start-up mm:ss This message is displayed at start-up, if a value different from zero has been
entered in parameter P15 (start-up delay), and shows the countdown of this delay.
Once the delay has elapsed, the message disappears.
pH Stabiliz. mm:ss This message is displayed at start-up, if the pH value is not at its threshold and
therefore the waiting time for pH stabilization (parameter P17) has been triggered.
This message shows the countdown of this delay. Once the delay has elapsed or
the pH threshold has been reached, the message disappears.
Level 1 failed Low level in tank 1 (acid). Add liquid to restore the level.
Level 2 failed Low level in tank 2 (chlorine). Add liquid to restore the level.
Al. MAX T Pump1 Pump 1 has dosed for longer than the time set in P06 without reaching the desired
threshold. Check pump P1 for proper functioning and, if necessary, the value set
in P06 (maybe too short for the installation). Cancel the alarm by pressing twice
the ON/OFF key.
Al. MAX T Pump2 Pump 2 has dosed for longer than the time set in P13 without reaching the desired
threshold. Check pump P2 for proper functioning and, if necessary, the value set
in P13 (maybe too short for the installation). Cancel the alarm by pressing twice
the ON/OFF key.
Manual Stop The ON/OFF has been pressed.
Flow mm:ss The consent to the Flow input is missing. The displayed time is the value set in
parameter P16. Once the consent is restored, the time countdown starts, and when
reaches zero, the alarm disappears.
Maintenance P1 Request of maintenance for pump 1 (pH/acid). Once completed the maintenance
operations, reset the litre-counter (and therefore the warning message) by entering
the correct password in P27.
Maintenance P2 Request of maintenance for pump 2 (chlorine). Once completed the maintenance
operations, reset the litre-counter (and therefore the warning message) by entering
the correct password in P30.
Alarm Meas.1 In case of input 1 signal too low or too high, the unit shows the meassages UR
(Under Range) or OR (Over Range) in the area normally reserved to the
measurement 1. In these conditions the input signal is not reliable and, therefore,
an alarm is generated, with consequent stop of the dosage.
Check for the correct connection of the signal cable, the general conditions of the
sensor, and possible strong oxidations.
Alarm Meas.2 As above, but referred to input 2.
