Reduce output voltage appropriately, then restart the output.
Install the controller in a well-ventilated environment.
Make sure no extern power supply connect to the 24V power
port or contact our technical support.
Make sure the work temperature not under -20℃ or contact
our technical support.
Make sure the load of Port D is not short-circuit and the current
does not exceed 400mA, then try to restart the output of Port D.
Make sure 24V port is not short-circuit and the current does
not exceed 400mA.
Make sure the 5V power of Port A is not short-circuit or not
connected to external power voltage more than 5V.
Make sure two input signals of RS trigger of Main output are
not valid at the same time.
Make sure two input signals of RS trigger of Port D are not
valid at the same time.
Make sure the motor is not overloaded or the motor is not locked.
Make sure that the actual speed of the motor is not lower than
the set minimum speed value.

Make sure the Output Cable is reliably connected to the
vibrator.
Make sure the output voltage is not small.
Make sure the Stop Indicator is not light up.
Please check whether Normal Close of parameter has been
set, causing controller output to stop.
Avoid vibration coupling among the vibrators.
Heighten the resonant frequency of the vibrators.

Make sure the control signal is correctly inputted.
Make sure the ground wire of the control signal is correctly
connected to the controller.
Make sure the Logical Relation of the control signals is set
correctly as your expectation.
Make sure the power outlet is live
Make sure the Input power Cable is reliably connected to the
power outlet?
