Time Alarm - Perle MP-DUAL-PH/RX Manual De Regulatión

the GAIN calibration of the probe. If it is necessary you can modify the value of the buffer solution shown in the second
line of the display using the buttons + or -. Push CAL to confirm.
If you read the message "Calibration Impossible" the probe calibration is not saved. Read the following paragraph
named "DUAL MESSAGES". If no error message appears the calibration has been made.
DUAL MESSAGES

TIME ALARM

WHAT IS IT? The Time alarm is expressed in units (0-120unit) of dosage. One unit is equivalent to 1 minute of
chemical dosing (or RX plug activity in DUAL pH/REG). The units counting starts from 0 when the pump starts dosing
after the power on, it increases during dosing, it stops during level alarm and stand_by state, it is reset when the power is
off, when the measure reaches the setpoint and during the flow alarm. When the counting reaches the value memorized
in Time alarm, the system goes in Time Alarm state
1) The dosing stops (no tension to the Rx plug in DUAL pH/REG system)
2) Green led On blinks
3) the display shows:"Tal" and the the measure on the second line. (See figure here above).
Push STB button to bring back the pump in the Operating mode and to reset the count of Time Alarm
which re-starts with the dosing (or activity of the plug in DUAL pH/REG)
MOD l/h 1 unit
DUAL-PH_1.5liters 1.5
DUAL-RX 3liters
FLOWRATE VISUALIZATION
During the functionnig it is possible to visualize the actual measures or the actual dosing flowrates (or actual activity of
Rx lug in DUAL pH/REG) simply pushing the ESC button. You can change the visualization pushing again ESC. (See
the figure above)

IT WARNS MEANS THAT THE CALIBRATION IS IMPOSSIBLE. IT IS
NECESSARY TO DO IT AGAIN.
If you read the same message again after you repeated the calibration:
a) Check that the buffer solution is not polluted or contaminated (change it in this
case).
b) Check that the buffer solution selected on the display during the calibration is
the value of the one ractually used.
c) The pH probe could not be working well (change it in this case)

TIME ALARM EDITING
Push CAL 3 times and scroll the menu (+/- buttons) until the display
shows" pH Alarm Time". Push CAL to enter and choose the alarm
time units from 0 to 120 using + and – buttons.
Push CAL to confirm and ESC to go back to measure.
Calculation example of the Alarm Time if you wish to inject 2
liters(=2000cc) of maximum product at backpressure of the
pump nameplate.
NOTE: The time alarm has no effect on Manual mode
operation
