PRIMING FUNCTIONS

To facilitate pump priming, it is equipped with the PRIMING function. It is recommended to open the purge bypass on the pump
bodies (for eTwin with electromagnetic hydraulics) during the priming operations. The air purge fitting must always be connected to
the relative tube with return to the suction tank.
This function can be activated in any operating mode (MEASURING or IN PAUSE) as follows:
Press and hold the UP ARROW key for left hydraulics, or the DOWN ARROW key for right hydraulics.
•
After about 5 seconds, the pump begins to dispense injections at the priming frequency (120 pul/min for electromagnetic pumps,
•
at maximum speed for peristaltic pumps) until the operator releases the UP/DOWN ARROW key. The following screen appears
on the display while pressing the key:
The PRIMING function can be activated even if the pump is protected by PASSWORD.

SET-POINT CONFIGURATION MENU

Set t in g p H, R x Ch lo ri n e p ar am et er s

The following tables show the sequence of operations to set the operating parameters of the measurement on channel 1, Ph or
Cl. The same process can be applied to channel 2 of the measurement (pH, Rx, Cl).
The current and stored values are highlighted with a dot to the right of the value.
Default set-point values 7.20 pH, 700mV, 1,50ppm.
In the set-point programming menu of the pH, Rx and Chlorine (PPM) modes, the following can be set:
SET-POINT: intervention value and mode
•
INTERVENTION TYPE: defines the field of application of the instrument
•
HYSTERESIS: range around the set-point value within which the pumps are not activated. When the measurement leaves this
•
interval, the pumps are activated
TEMPERATURE: compensation of the measurement relating to the temperature (only for pH if enabled in MANUAL mode – see
•
chapter Temperature)
