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 electrode and connection cable;
check that the calibration solutions are not expired
or contaminated; repeat the procedure.
MAINTENANCE
The periodic maintenance operations are essential for the proper functioning of the
system and its duration in time. The below advices should be strictly followed.
Before any operation, make sure the system is unplugged!
Dosing Pumps
Weekly operations:
•
Check the level of the solution to be dosed to prevent the pump from running dry.
•
Check that the suction and head pipes are clean and not containing any impurities.
•
Check that the filter is not clogged to avoid the decreasing of flow rate.
Operations every three months
(or in case of pump drifting):
RClean all the parts that come into contact with the chemical (pump body, foot filter and
injection valve). If the pump doses additives that from crystals, clean more frequently.
Proceed as follows:
•
Dip the suction tube and the foot filer into clean water.
•
Start the pump and leave it run for a few minutes to let the water wash the pump head.
If there are crystals to remove, proceed as follows:
•
First use a proper chemical (instead of water) to dissolve the
crystals and let the pump work for a few minutes.
•
Repeat the procedure with clean water.
Once the cleaning is done, connect again the pump to the plant and resume normal operations.
