4.4 INHIBITING ALARM
The inhibiting alarm starts when a dosage fails because the recirculation pump signal failed to stabilize in the
programmed time frame
tn.A
): this alarm is disabled if
In.E
is "no", that is if the dosage does
not depend from the recirculation pump activation.
The wait time for the inhibiting signal stabilization is calculated from the time when the scheduled time for the daily
dosage expires.
The inhibiting alarm is reported by the pump in the following way:
▪
Audio signal via the buzzer (if there is one on the pump) if enabled (see
bu.E
in the "
) with a
frequency of 1 second on and 1 second off;
▪
flashing red LED;
▪
“
AL.I
” flashing on the display;
The alarm will be disabled if:
▪
The time of the following daily dosage starts;
▪
The equipment is turned off from the switch or the power supply;
5.0 MAINTENANCE
This section reports the general rules you need to follow to operate the pump correctly and the steps to carry out
periodically to ensure optimal conditions are maintained over time.
5.1 GENERAL RULES
Maintenance operations must be conducted systematically and accurately by following the recommendations
reported below to the letter.
It is difficult to define the standard times required for maintenance beforehand, as there are a number of factors
that determine the wear of the pump and in particular the parts that are in contact with the liquid.
This also applies to the type of product used to clean the materials that are in contact with it (valves, etc.) as it
depends on the compatibility of the material with the chemical product being dosed.
Having said this, we can take as an example a product, such as sodium hypochlorite, that develops crystals, which
is often used with our pumps, and with which we have a great deal of experience, and identify the type of
maintenance required.
5.2 PERIODIC MAINTENANCE
▪
Check the foot strainer and clean it periodically from any residuals of crystallised product or dirt deposits;
▪
Ensure there are no impurities in the suction and delivery tubes, because they may damage the peristaltic
tube and, at the same time, cause anomalies in the flow rate;
▪
The pump materials that are in contact with the chemical product, such as the foot strainer and the
injection valve, must be checked and cleaned at least every three months
. If the products are particularly
aggressive increase the frequency of cleaning;
▪
Calibrate the pump periodically;
To remove and reassemble the peristaltic tube refer to the steps described respectively in Figures 14 and 15.
