Built in bypass type intelligent motor soft starter/cabinet
Risk of electric shock
There is voltage at the following positions, which may cause serious electric shock accidents and can be fatal:
● AC power cord and connection
● Output wires and connections
● Many components of starters and external optional equipment
Before opening the starter cover or performing any maintenance work, the AC power supply must be isolated from the starter with an approved isolating device.
Warning-risk of electric shock
As long as the supply voltage is connected (including when the starter is tripped or waiting for a command), the bus and the heat sink must be considered live.
Short circuit
Cannot prevent short circuit. After a severe overload or short circuit occurs, an authorized service agent should fully test the soft start working conditions.
Grounding and branch circuit protection
The user or installer must provide proper grounding and branch circuit protection in accordance with the requirements of local electrical safety regulations.
For safety
● The stop function of the soft start does not isolate the dangerous voltage at the output of the starter. Before touching the electrical connection, the soft starter must be disconnected with an approved electrical isolation device.
● The soft start protection function is only applicable to motor protection. The user must ensure the safety of machine operators.
● In some installation situations, accidental starting of the machine may endanger the safety of machine operators and may damage the machine. In such cases, it is recommended that you install an isolating switch and circuit breaker (such as a power contractor) that can be controlled by an external safety system (such as emergency stop and fault detection period) on the soft starter power supply.
● The soft starter has a built-in protection mechanism, and the starter trips when a fault occurs to stop the motor. Voltage fluctuations, power outages and motor jams can also cause the
motor to trip.
● After eliminating the cause of the shutdown, the motor may restart, which may endanger the safety of some machines or equipment. In this case, proper configuration must be made to prevent the motor from restarting after an unexpected shutdown.
● The soft start is a well-designed component that can be integrated into the electrical system; the system designer/user must ensure that the electrical system is safe and meets the requirements of the corresponding local safety standards.
● If you do not comply with the above recommendations, our company will not bear any responsibility for any damage caused thereby.

Note: The water supply function starts and stops controlled by IN3, the standard soft start IN3 is an external fault, and the water supply type is used to control the start and stop. IN3 is the starting end, and the above operation can be performed only when it is closed, and it stops when it is open.
Troubleshooting
Protection response
When a protection condition is detected, the soft start writes the protection condition into the program, which may trip or cause Issue a warning. The soft start response depends on the protection level.
Users cannot adjust some of the protection responses. These trips are usually caused by external events (such as phase loss) It may also be caused by internal faults in the soft start. These trips have no relevant parameters and cannot be set as warnings orIgnored.
If The Soft Start Trips, You Need To Identify And Clear The Conditions That Triggered The Trip, Reset The Soft Start, And Then Proceed Restart. To Reset The Starter, Press The (stop/reset) Button On The Control Panel.
Trip messages
