Snap action mode

Output waveform of jump start mode. This starting mode can bese lected when the motor cannot be started under some heavy load due to the influence of static friction force. When starting, first apply high fixed voltage to the motor for a limited period of time to overcome the static friction force of the motor load to make the motor rotate, and then start in the way of limiting current(figure 1) or voltage slope(figure 2).

Current range......................11A-1260A(rated)

Power supply
mains input(R,S,T)

Terminals(1) and(2) are operation output: used to control operation indication(output). They are normally open passive contacts and close when starting successfully.
Contact capacity: AC250V/5A.

Terminals 3 and 4 are output 1 of the programmable relay:delay time is set by the programmable output 1 of A12, and action mode is set by the programmable relay 1ofA11. Is normally open passive contact, closed when the output is effective. Possible values:0: No action 1: power-on action 2: soft start action 3: bypass action 4: soft stop action 5: Running action 6: standby action 7: fault action 8: current arrival action Contact capacity is AC250V/5A.

Terminals ⑤ and ⑥ are output 2 of the programmable relay: the delay time is set by A14 programmable output 1 delay, and the action mode is set by A13 programmable relay 1. Is normally open passive contact, closed when the output is effective.
0: No action 1: power-on action2: soft start action 3: bypass action 4: soft stop action5: Running action 6: standby action 7: fault action 8: current arrival actionContact capacity is AC250V/0.3A.

Terminal ⑦ is a transient output: This terminal must be short-circuited with terminal 0 when the soft starter is working normally. When this terminal is open to terminal 0, the soft-start cabinet stops working unconditionally and is in fault protection state. This terminal can be controlled by the normally closed output point of the external protection device.
When FA is set to 0(primary protection), this terminal function is disabled.

Terminals 8,9, and 0 are input terminals for externally controlled start and stop buttons. The wiring method is shown in the figure.

Terminals(11) and (12) for 4~20mtA DC analog output: used for real-time monitoring of motor current, full 20mA indicating motor current for soft starter nominal rated current 0.5-5 times, can be set by the parameter A17.4-20mA upper limit current.
Can be connected to 4~20mA DC ammeter observation.

Terminals (13) and (14) are RS485 communication output and provide Chinese upper computer software for remote debugging and control. Do not disconnect the external terminal line; otherwise, the soft starting cabinet may be damaged.
