Line n.2 STOP XX
Indicates delay time, in seconds, for stopping the second pumps in the presence of suitable pressostatic conditions for stoppage.
• MINIMUM: 0 tenth of seconds
• MAXIMUM: 99 tenth of seconds
Follows the insertion of START and STOP parameters of the other pumps.

YES The inverter is associated to the pumps indicated in the second line.

Line n.2 EXTERNAL CONTR. (external control)
NO
The inverter is moved on the different pumps according to the logic of the cyclic inversion of the program at the end of each working
cycle.
If
Line n. 2 EXTERNAL CONTROL
YES
The inverter is moved on the various pumps according to the cyclic inversion logics of the program at the successive starting up
after the closing of an external contact (for example: timer) or after the closure of an external contact (example: daily timer). In this
case the change of pump under inverter occurs after the first pause (the external contact must be of short length and in any cases
opened before the operational pause of the group).
Cyclic inversion logics: at every beginning of the working cycle, the pump which has been last started is enabled first. During the
working of the group the pumps controlled directly are stopped in reverse order respect to the one start up order.
Example: GROUP WITH 4 PUMPS
• FIRST PUMP STARTED UP: controlled by the inverter of pump 2
• SECOND PUMP STARTED UP: direct control of pump 3
• THIRD PUMP STARTED UP: direct control of pump 4
If the drawing is reduced, pump 3 is the first ti stop, then pump 4, after the stop o alla the pumps:
• FIRST PUMP STARTED UP: controlled by the inverter of pump 3
• SECOND PUMP STARTED UP: direct control of pump 1
• THIRD PUMP STARTED UP: direct control of pump 2
