This key allows you to set the maximum dosing time. This function stops the pump after the
programmed run time has elapsed in order to prevent overdosing in the event of a
malfunction (sensor malfunction, low level in the reagent tank, etc.)
PROGRAMMING THE MAX DOSING TIME ALARM
Keep the
SAFETY
key pressed down until the LED lights up. The allowed values are expressed in hours
and are shown on the pH/Hr display. Press the
ON/OFF
key repeatedly to select the maximum dosing time.
To save the setting, keep the
SAFETY
key pressed down until the LEDs on the pH/Hr display light up one
after the other starting at the bottom.
Example: if
0
is selected, the dosing alarm is inactive. If
2 Hr
is selected, the pump will stop after 2 hours
of continuous operation. *** As the pump injects a maximum of 2l/h, after 2 hours at most 4 litres of the
reagent will have been injected.
The max dosing time should be programmed as a function of the pool water volume.
There are 2 ways to reset the max dosing alarm (
max dos
):
RESETTING THE MAX DOSING ALARM WITH MODIFICATION OF THE DOSING CYCLE
Hold down the
SAFETY
key. The dosing cycle (expressed in hours) is shown on the pH/Hr display scale. Press
the
ON/OFF
to cycle through the allowed values. To save the new setting, keep the
SAFETY
key held down
until the LEDs light up one after the other starting at the bottom of the pH/Hr display scale. The pump will restart
when a demand is detected.
RESETTING THE MAX DOSING ALARM WITHOUT MODIFICATION OF THE DOSING CYCLE
Hold down the
SAFETY
key. The dosing cycle (expressed in hours) is displayed on the pH/Hr scale. Release
the key. Keep the
SAFETY
key held down again until the LEDs light up one after the other starting at the
bottom of the pH/Hr display scale. The pump will restart when a demand is detected.
This key is used to calibrate the probe. A pH 7 buffer solution will also be required. To
enter Calibration mode, keep the key held down for 5 seconds, the LED lights up.
Remove the protective cap from the probe and connect it to the BNC terminal marked
“pH” underneath the pump. then plunge the tip of the pH probe into the pH7 buffer
solution. Wait 1 minute for the reading to stabilise while stirring the probe gently in the
solution. To save this value, keep the
CALIBRATION
key held down until the LEDs light up
successively starting at the bottom of the pH/Hr scale.
The LED that lights up on the pH/Hr scale should correspond to a pH of 7. If this is not the case, press
the
ON/OFF
key repeatedly until the LED corresponding to a pH of 7 lights up. To save this setting,
keep the
CALIBRATION
key held down until the LEDs light up successively starting at the bottom of
the pH/Hr scale.
LEVEL
If the low level sensor detects a low level in the reagent tank, the relevant LED will flash and the pump
will be stopped.
The pump will automatically restart once the reagent tank has been refilled.
