Warranty
For B503DSL series controller, our company provides 12 months warranty after the date
of leave factory.
 
Common Faults and Solutions
Controller may have following faults or malfunctions during operation, please refer to the
following solutions.
1.No display after power on:
(1) Inspect whether the voltage of power supply is the same as the controller rated
voltage or not with multi-meter. If the power supply has problem, inspect and solve it.
(2)Check the CHARGE light. If the light is off, Please ask for support. If the light is on,
the fault may be lies in the switching power supply. Please ask for support.
2. Power supply air switch trips off when power on:
Inspect whether the input power supply is grounded or short circuit. Please solve the
problem.
3.Motor doesn't move after controller running:
(1)Inspect if there is balanced three-phase output among U, V, W. If yes, then motor
could be damaged, or mechanically locked. Please solve it.
(2)If the output is unbalanced or lost, the controller drive board or the output module
may be damaged, ask for support.
4.Controller displays normally when power on, but switch at the input side trips
when running:
(1)Inspect whether the output side of controller is short circuit. If yes, ask for support.
(2)Inspect whether ground fault exists. If yes, solve it.
(3)If trip happens occasionally and the distance between motor and controller is too far,
it is recommended to install outputAC reactor.
