Mains and control description
3.4.1
Mains Voltage (line to line) (Terminals/bars L1, L2, L3)
Five mains voltage levels are available: 230V, 400V, 440, 480V, 600V.
Note:
230
220 - 240 Vac +10% -15%
400
380 - 415 Vac +10% -15%
440
440 Vac +10% -15%
480
460 - 500 Vac +10% -15%
600
575 - 600 Vac +10% -15%
3.4.2
Start (Terminals 1, 2)
Start/Stop command is initiated by closing/opening a voltage free contact (Dry contact)
Close: Start command.
Open: Stop command.
WARNING!
Never apply voltage to terminals 1, 2.
Start/Stop with a maintained contact!
When the line contactor is operated by a maintained contact, in case of Mains
failure, the motor will be automatically restarted upon voltage restoration!
3.4.3
Neutral (Terminal 3)
Neutral wire (when used) is required only for operation of the Phase Loss Protection (Phase Loss can not be
detected when Neutral is not connected to Terminal 3).
See detailed description in “Phase Loss” explanation section
3.4.4
Open terminal (Terminal 4)
This terminal is of no use. Leave this terminal not connected.
3.4.5
End Of Acceleration (terminals 5, 6)
Voltage free, N.O., 8A / 250VAC, 1800VA max.
The contact closes after the time adjusted on the "Ramp-Up" potentiometer. The contact returns to its original
position on stop signal, on fault condition, upon voltage outage and at the beginning of Soft Stop.
This contact can be used for:
•
Activating a valve after a compressor has reached full speed.
•
Activating a valve after a pump has reached full speed.
•
Loading a conveyor after the motor has reached full speed.
3.4.6
Fault Contact (terminals 7, 8)
Voltage free, N.O , 8A, 250VAC, 1800VA max.
The contact changes its position upon fault and returns to its original position after fault has been removed
and starter was reset. When disconnection of mains supply the contacts will be opened.
WARNING!
Do not use the Fault contact to trip an upstream contactor!
When the Fault contact trips the upstream contactor, Mains voltage will be
disconnected, thus resetting the starter and the motor will restart instantaneously
upon voltage restoration. (See also section
When resetting after a fault with the Reset button, the motor will restart upon
fault reset.
It is therefore recommended not to connect the fault relay to the line contactor.
