Details of electrical connections
– Loosen the screws and remove the converter cover.
CONNECTION TO MAINS SUPPLY
–
Connect the cable 4 wires
(3 phases + earth)
CONNECTION OF INPUTS/OUTPUTS
– Control of the converter by an external
system with a signal (0-10V) or 0-20mA)
A removable jumper has to be placed
according to the type of signal.
- Control with a current signal ............................
put the bridge in low position.
- Control with a voltage signal ...........................
by default the bridge is in high position,
if not carry out the change.
- Possibility to have a remote control ................
(free contact).
CONNECTION OF THE SERIES CONTACTS
The speed variator is fitted with an output relay with
free contact aimed for an interface to centralized control
For example : control box, pumps control...
«Available transfer» relay :
Bornes : 41 - 42 - 43
- feature of the contact .....................................
The relay is actived when the pump runs or
is in a position to run.
When a first defect appears or by mains supply
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.
