OTHER REGULATION
In mode "other regulation – Mode 2", connections are identical to those described previously
(the pressure sensor being indeed on replaced by a sensor adapted to the wished type of regulation).
MODE EXTERNAL CONTROL
3) In mode with external control : Mode 3
– By current signal
– The remote control allows the switching On or
Off of the pump (free contact), this function
has priority on the others.
– This remote control can be removed by
shunting the terminals (3 and 4).
CONNECTION FOR THE SERIE CONTACTS
The converter is fitted with 2 output relays with free
contact" aimed for an interface to centralized control.
Example : control box, pumps control...
1) Available transfer "relay" : SBM
–feature of the contact...................................................Free contact
The relay is activated when the pump
runs or is in a position to run.
When a first defect appears or by main supply
cutoff (the pump stops), the contact is closing.
Information is given to the control box,
regarding the un-availability of the pump,
even temporarily.
2 2 ) Failures transfer "relay" : SSM
–feature of the contact...................................................Free contact
–After a series of detection (from 1 to 6
according to significance) of the same type of
defect, the pump stops and this relay is
activated (up to manual action).
