Single-phase version
In the standard configuration (jumpers JMP2 and JMP3 disconnected) 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 configuration can be used for example in the case of maintenance or if neces-
sary to disconnect an electric pump from the group.
Note: The jumpers must be connected when the electric power 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.
