Lovato Soft Starter 75A (37kW) B type, 415VAC with Internal By- Pass
General characteristics
ADX is a reduced voltage soft starter with torque control
and maximum starting current limit. It is used for the
progressive starting and stopping of asynchronous
three-phase squirrel-cage motors.
The integrated by-pass contactor ADX...B types only,
drastically limits dissipation, as a result equipment for
electric panel cooling ventilation can be eliminated and
the enclosure size can be reduced as well.
CONTROL
During starting: Torque control acceleration, current limit
control and booster.
During stopping: Torque control deceleration, dynamic
braking and free-wheel.
In emergency conditions: Starting without protections,
direct-on-line starting using integrated by-pass contactor.
Remote control: PC supervision by connection with
RS232/RS485 converter, modem or GSM modem.
Automatic call function (Autocall) in case of alarm
conditions by sending a message to a cellular phone
(SMS-Short Message Service) and/or to a mailbox.
Property ASCII and Modbus®-RTU communication
protocols.
KEYPAD OPERATIONS
- Liquid-crystal backlit 2-line 16-character display
- Multilanguage capability (Italian, English, French,
Spanish)
- Basic, advanced and function programming menus
- Keypad stop and start

PARTICULAR FUNCTIONS
Digital inputs and programmable relay outputs. Analog
input (0...10V, 0...20mA or 4...20mA) for ramp
acceleration and/or deceleration, motor starting and
stopping control thresholds, programmable relay enable
and disable control thresholds. Analog output
(0...10V, 0...20mA or 4...20mA) for current, torque,
motor thermal status and power factor readings.
Input programming for second motor.
PROTECTIONS
- Motor: Dual thermal protection class (one during
starting phase and the other during running) or by
PTC sensor, locked rotor, current asymmetry,
minimum torque and starting time too long
- Auxiliary voltage: Voltage value too low
- Power voltage: Phase failure, phase sequence and
frequency out of limits
- Control inputs and analog output: Static 24VDC
short-circuit protection with automatic resetting.
- Starter: Overcurrent, high temperature, SCR and
by-pass contactor malfunction.
