PARAMETER 09 DOSAGE DIRECTION OF PUMP 2
See parameter P04, but referred to redox measurements and
dosing directions “Chlorination / De- chlorination”.
PARAMETER 10 TIME BASE FOR PUMP 2
See parameter P05, but referred to the pump 2.
PARAMETER 11 DOSAGE ALARM OF PUMP 1
This parameter allows to generate an alarm when the measurement does not return to the setpoint
value within a set time interval, from 0 (function disabled) to 240 minutes. The counter starts when
the unit detects a measurement that exceeds the setpoint value, and automatically resets to zero
when measurement returns to an acceptable. If measurement remains outside of the setpoint for
a time longer than that set, an alarm is generated, the display shows the message “Al.1” and the
pump stops dosing. To reset the alarm and resume to normal operations, press the ON/OFF button
or shutdown and restart the unit. This condition can occur when the dosage is insufficient to reach
the setpoint (P02).
PARAMETER 12 DOSAGE ALARM OF PUMP 2
See parameter P11, but referred to pump 2.
PARAMETER 13 START-UP DELAY
This parameter allows to set a start-up delay, which is a time of waiting before starting
measurements to allow the correct polarization and stabilization of the measuring electrodes. This
prevents unreliable initial readings. Typically in the case of pH measurements one minute is enough,
while for redox electrodes may be necessary a delay of 30 minutes. This waiting time also allows to
compensate for any hydraulic delays which may occur at the start-up of the plant.
Set a time (in minutes) during which, after turning on the electronic unit, the system waits,
measurements blink on the display and the pumps are not active. After this time, the system begins
normal operation.
PARAMETER 14 LANGUAGE
This parameter allows to select the display language.
PARAMETER 15 RESTORE THE DEFAULT SETTINGS
This feature allows to restore the factory configuration if you want to delete
incorrect or undesired settings. Once confirmed this option, all custom
setting will be lost. To enable the feature, enter the value “12”.
