Mains and control description
3.4.1
Mains Voltage (line to line)(Terminals/bars L1, L2, L3)
Four mains voltage levels are available: 208V, 400V, 480V, 600V.
Note:
208V applies for 208V-10% up to
220V
+15%
400V applies for 400V-10% up to 400V+15%
480V applies for 480V-10% up to 480V+15%
600V applies for 600V-10% up to 660V+15%
3.4.2
Control Voltage (Terminals 1, 2)
The Solstart Plus incorporates a universal power supply unit for DC and AC control voltage.
110-230V, 50/60Hz or 110-230VDC (+10%/ -15%) is required to power the electronic circuitry and the bypass.
This voltage can be from a grounded or ungrounded mains system.
3.4.3
Discrete input voltage (Terminals 3, 4)
Apply discrete input voltage to terminals 3 and 4 to soft start the motor.
To stop the motor disconnect the control voltage from terminals 3 and 4. If Deceleration time is set to a value
other then 0 seconds the motor will soft stop.
Discrete input voltage should be in the same range as control voltage: 110-230V, 50/60Hz or 110-230VDC
(+10%/ -15%).
This voltage can be from a grounded or ungrounded mains system.
3.4.4
End Of Acceleration (terminals 5, 6)- Solstart Plus 58A and up.
This contact exists in Solstart Plus 58A and up.
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.
3.4.5
Fault Contact (terminals 7, 8)
Voltage free, N.O , 8A, 250VAC, 1800VA max. Solstart Plus 58A and up.
Voltage free, N.O , 5A, 250VAC, 1250VA max. Solstart Plus up to 44A.
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 control supply the contacts will be opened.
3.5
Built-in Bypass
The Solstart Plus incorporates two internal bypass relays allowing current flow through the thyristors only
during starting process. At the end of the starting process, the built-in relays bypass the thyristors and carry
the current to the motor.
Upon stop signal, or in case of fault, both bypass relays will open and stop the motor.
When Ramp-Down potentiometer is set to allow soft-Stop process, upon stop command, the bypass relays will
open immediately and the current will flow through the thyristors. The voltage will then be reduced slowly and
smoothly to zero.
