7. Common problems and solutions
When the module does not work properly, please check in turn:
(1) the connection of the power line and the condition of the relevant
switches and protection appliances, so as to ensure the reliable power
supply of the module;
(2) whether the wiring of user terminals is firm;
(3) check whether the 24Vdc power supply is overloaded.
(4) check the application to ensure that the correct operation method
and parameter range are selected in the application. Special attention
should be paid to the BFM area with special operation timing.
If you still cannot work after the above check, please refer to the
following table.

Possible Causes
Countermeasures
POWER and
other LED are
off
Loss of power supply or low
voltage
Check the power status and
eliminate
Power switch off or fuse
blown
Check the condition of the
switch, wire or fuse and
eliminate it
Abnormal power wiring
Power supply is damaged
Check and confirm: whether
the voltage between 24V +
and 24V- terminals is within
the normal range
POWER LED
flashes
intermittently
Unstable power supply
Module damaged
RUN LED is off
or on
Module shutdown or crash
Replace the module

．
The warranty period is 18 months
, during the warranty period of
normal use, the product failure or damage, our company free
maintenance.
3
．
T
he warranty period starts from the date of production
. The
machine code is the only basis to judge the warranty period. The
equipment without machine code shall be treated as overinsured.
4. Even within the warranty period, a certain maintenance fee will be
charged if:
(1)Failure to operate according to the user's manual;
(2)Machine damage caused by fire, flood, abnormal voltage, etc.
(3)Damage caused when a programmable controller is used for
unusual functions.
(4)Self-disassembly programmable controller
5. The service fee shall be calculated according to the actual cost. If
there is another contract, the contract shall take precedence.
6.If you have any problem, you can contact the agent or contact us
directly.
