SSR series soft starter are all digital motor soft start products, It may control the motor started and stopped on a smooth speed changing, It also offers the best protections to motor and itself. It is the better substitute control method to the traditional A-Y motor start and auto transformer start Control.
◆ Built-in bypass
◆ Multiple protections
◆ Spacing saving
◆ Three/Single phase control
◆ Optional communication
◆ Easy control

Soft Starter Wiring Mode:
Control power supply and control input:
When using 100-240VAC as a control power,
①Connect AC power line, ②Connect AC power neutral;
Join the contact K between①and③,
Soft starter runs when K closed, soft starter stops when K disconnected; If the control input cable too long or unseparated wiring with power supply, cause input signal with "Induced voltage" Please add a relay at the input, so as to avoid the"induced voltage " which leads to malfunction or damage of the soft starter.
When using 24VDC as control power,
①Connect to DC+, ②connect to DC-;
Join the contact K between①and③,
Soft starter runs when K closed, Soft starter stops when
K disconnected; If the control input cable too long or
unseparated wiring with power supply, cause input signal with "induced voltage" Please add a relay at the input, so as to avoid the "induced voltage" which leads to malfunction or damage of the soft starter.
The control power supply voltage must be matched the products, otherwise the input of the control voltage will exceed the range, which will lead to soft starter damage.
When the control power supply is DC power, the positive and negative pole must be connected to the correct terminal.
④，⑤ terminal for running relay output.
When SLR soft starter is on running (start/ bypass/ soft stop),
K1 closes. ⑥⑦ terminal is fault relay output, When the SLR soft starter detects a fault K2 closes. K1, K2 contact capacity 220VAC 5A
In order to use the SSR soft starter safely, The fault relay K2 should be connected in the circuit of the control(release )of the circuit breaker between the power source and the SLR main power terminal. When he soft starter detects the fault, the K2 action can disconnect the power breaker at the same time.
