Single-phase version
In the standard configuration (jumpers JMP2 and JMP3 dis-
connected) the group operates in a cyclical manner (1duty - 1
assist). Acting on the configuration jumpers JMP2 and JMP3
on the card it is possible to modify the working mode.
JMP2 connected: Mode 1 duty - 1 standby: in this case one
pump will be activated in a cyclic manner (except in case of
alarm or removal of an electric pump). The reserve pump will
be activated only in the event of an alarm or electric pump
before the next cycle.
JMP3 connected: second electric pumpd excluded. This con-
figuration can be used for example in the case of maintenance
or if necessary to disconnect an electric pump from the group.
Note: The jumpers must be connected when the electric pow-
er is off.
Three-phase version
In the standard configuration, the group operates in a cyclical
manner (1duty - 1 assist). By changing the positions of the
contacts of the switch S3, located at the back of the card, it is
possible to modify the working mode.
