and to see if the phenomenon reoccurs.
ORP LOW: this message is displayed when the
525 mV.
resolve the problem by carrying out the following
steps in the order indicated (if the problem is not
correct.
Check that the probe is clean and
undamaged.
Using a recently calibrated photometer,
measure the concentration of free Chlorine in
the pool water to see if this value corresponds
displayed.
enough each day (at least 10 hours a day
during the pool season)
Visually inspect the cell to verify that it is
producing and that the electrodes are not
covered in scale.
Check the stabiliser (Isocyanuric acid)
concentration in the pool. It should be between
30 and 50 mg/l
Increase the concentration of free Chlorine
and wait to see if this phenomenon reoccurs.
All these alarms are automatically reset when the
parameter returns to within an acceptable range.
• PH OR REDOX PROBE FAULTS (EES PRO ONLY)
PH PROBE: pH probe not detected.
ORP PROBE
Cut power to the electrical/ control panel,
open the connection terminal compartment
and check that the two probes are properly
connected at the correct positions on the PCB.
Remove the probe PCB from its housing
and check that the pins are clean and in good
condition. Reinsert it fully into its housing.
Inspect the entire length of the wires of
each probe and make sure that they are not
damaged.
Close the by-pass loop shut-off valves and
remove the probes to check them for damage.
• PH/REDOX CIRCUIT BOARD FAULT (EES PRO ONLY)
NO CARD probe connection board not detected.
Cut power to the electrical/ control panel,
open the connection terminal compartment.
Remove the probe PCB from its housing
and check that the pins are clean and in good
condition. Reinsert it fully into its housing.
X. MAINTENANCE
• MAINTENANCE OF PH AND REDOX PROBES (EES PRO ONLY)
During use, scale may build up on the pH and
on their tips. This may be the case if their response
times are getting longer.
The probes should be removed from their mounting
sure that the by-pass loop inlet and outlet shut-off
valves are closed, and place a bucket under the tee
to collect any water).
