6.1.2 Mode with regulation : MODE 2
The pump can run in different regulation types (pressure, temperatu-
re, flow,...).
The P , I, D factors are fixing on the software for the pressure regulation.
And on the other hand, for another regulation, the P , I, D factors will be
configurated when you put in parameters.
MODE 2 : Pressure regulation (see fig. 6, 7 & 8)
The addition of a pressure sensor and a tank allows a pressure regu-
lation of the pump.
The accuracy of the sensor is ≤ 1% and it is used between 30 % and
100 % of the measuring scale range.The tank must have a useful volu-
me of 8L minimum (tank and sensor kit delivered as accessories).
Parameters input in MODE 2
- Set the switch (fig. 3 - item S) on position SERVICE.
- Select M2.
- Validate.
- Select the source of set value Internal/External.
Default "I"
(set value adjustment by touch pad).
- Validate.
- If the external set value "E" is validated, (set value adjustment by
external signal).
- Select the signal type (0-10V) or (4-20mA).
- Validate.
- Select the regulation type "P" for the pressure regulation.
- Validate.
- Select the range of the pressure sensor (6, 10 bar).
- Validate.
- Select the type of sensor (0-10V) or (4-20mA).
(the information which is blinking is the one validated).
- Validate.
- Select the stop delay (time between detection of zero output and
complete stop of the pump): range from 0 to 180 seconds (with
notice 180 s).
- Validate.
- Visualisation of the Operating time meter.
(number of pump operating hours).
- Validate.
- Set the switch back on position OPERATION.
Operating in MODE 2 and set value control with touch pads.
For the starting up, we recommend to set the motor speed at 60% of
its maximum pressure.
By impulse on the touch pads the requirement value can be changed.
- Validate the new value.
With a short impulse on the touch pads the actual pressure can be
displayed; the requirement pressure reappears after 30 seconds or
after on other impulse.
An impulse ~1s allows the ON/OFF function.
- Select OFF.
- Validate.
