CONNECTION OF THE SERIES CONTACTS
TERMINAL FOR SERIES CONTACTS
The speed variator is fitted with an output relay with
free contact aimed for an interface to centralized control

The relay is actived when the pump runs or

cutoff (the pump stops), the relay is no more
active. Information are given to the control box,
regarding the availability of the pump permanently.

The number of defects is stored thanks to a
counter.
If the number of defects is lower than 6 and if
after 10 sliding minutes no new defect has been
detected, so the number of defects of the
counter is reduced of 1.
The pump is permanently stopped the counter
count 6 defects. An impulse on the RESET
button initialize the counter.
