Imax, Imin, Restart Time And Inhibition Time Setting - toscano vigilec compact V1M Guide D'utilisation

13. IMAX, IMIN, RESTART TIME AND INHIBITION TIME SETTING

Automatic adjustment
The equipment adjusts itself with the 1st start-up. After the first 60 seconds, the equipment
registers the maximum and minimum current consumption of the pump. Then, the
controller sets the maximum current value a 10% above the maximum recorded current
and the minimum current value a 10% below the minimum recorded current. Make sure
the pump is primed and the discharge line is full during the calibration process. If this is not
the case, do not hesitate to repeat the process by selecting "CAL" in the Imax parameter.
In any case, the current absorbed by the pump at full load (nominal consumption) must
always be between the values of the motor overload (Imax) and motor underload (Imin)
current thresholds.
Maximum current allowed for the pump
Current at which the overload protection trips (adjustable from 0.6 to 20 Amps depending
on model). Overload trip time is 7 seconds. This fault activates the alarm output.
Minimum current allowed for the pump
Current at which the overload protection trips (disconnectable "OFF" or adjustable from 0.5
to 19,8 Amps depending on model). The underload trip time is 4 seconds except during 1st
start-up, which extends this time up to 20 seconds to allow correct priming of the pump.
●
Underload (minimum current or I.min) setting process to operate without level
probes
1
Close the inpulsion valve.
2
Run the pump in manual mode (see chapter 15).
3
Note the showed current consumption on the display.
4
Stop the pump.
5
Adjust the "I.min" parameter at least 0.1A above the
rated current before readed (see next page).
6
Start the pump again and verify that the underload is
detected and the pump stops.
7
Open the inpulsion valve.
8
Select the required reset time.
9
Reset the Vigilec Compact pressing the rotary knob.
