CM = 1 :

For each of the two exchange modes, if one of the machine breaks down, the other becomes the leader

and carries out regulation at constant pressure up to its maximum available power.

8.5.8

AE : Enabling the anti-frost function (pre-set value 1)

Starts rotating the motor-impeller assembly in order to avoid mechanical blockages.

When the anti-frost function is enabled, if the ACTIVE DRIVER measures a temperature that is too

low with a risk of frost, it automatically starts running the electropump at a low number of revs (25

Hz).

8.5.9

Setup of the auxiliary digital inputs IN1; IN2; IN3 with the parameters i1; i2; i3

(excluding A.D. M/M 1.1 and A.D. M/T 1.0)

The function assigned to each of the digital inputs IN1; IN2; IN3 may be activated or modified by

means of the parameters i1; i2; i3.

The setup of the parameters i1,i2,i3 may always assume the values:

0 => function disabled

1 - 3 - 5 => function active on high active input tied to the supply voltage + 12V(see fig. 1)

2 - 4 => function active on low active input tied to GND 0V (see fig. 1)

ATTENTION: The values 3 – 4 – 5 ONLY FOR INPUT IN3 AND PARAMETER i3.

8.5.10 Setting the set point P1 function of input 2 (excluding A.D. M/M 1.1 and A.D. M/T 1.0)

When the parameter i2 is set at a value other than zero, with the input 2 it is possible to select one of the

two settable set points. The first is SP. The second is P1. The regulating range is from 1.0 to 9.0 bar.

The primary and secondary ACTIVE DRIVER alternate in being the regulation leader.

The exchange takes place each time the leader ACTIVE DRIVER goes into stand-by

mode or after 2 hours of continuous activity.

If during operation the leader electropump is unable to satisfy the user and the

secondary electropump is set as a booster (Eb=2), the latter will work at maximum

frequency, while the leader ACTIVE DRIVER will continue to modulate the rotation

frequency according to the user.

If the user decreases, the leader machine goes into stand-by and becomes the booster

(off), while the booster machine becomes the leader (and starts regulating at variable

speed).
