• Loosen the screws and remove the converter
cover.
CONNECTION TO MAINS SUPPLY
Connect the 4 core cables on the 4 terminals
–
(3 phases + earth)
CONNECTION OF INPUTS / OUTPUTS
3 operating mode :
–
(See Chapter 6 : Starting up)
– Manual mode : Mode 1
– Single pump in regulation mode : Mode 2
– External frequency control mode : Mode 3
MANUAL MODE
1) In manual mode : Mode 1
– 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).
PRESSURE REGULATION
2) In mode with pressure regulation : Mode 2
– with pressure sensor 2 wires
– and adjustment of set value by encoder.
– with pressure sensor 3 wires
– and adjustment of set value by encoder
– with pressure sensor 2 wires
– and adjustment by external set value.
– with pressure sensor 3 wires
– and adjustment by external set value.
– The remote control allows the switching On or
