IAGNOSTICS
In order to simplify maintenance, this remote control system has been designed with a built-in self-diagnostics circuit in the
transmitter and receiver. As long as the micro control unit is in proper working condition, malfunctions in the pushbutton,
joystick, RF circuit, relay and relay driver circuits (including relay coil and relay contacts) can be detected. When a
malfunction occurs, the transmitter or receiver will generate a simple and clear alarm. Not only can the operator and
maintenance personnel fully understand the condition of the remote controller, but they can also reduce maintenance time by
following the error message for repair.
N
OTES
:
(1)
When an error message is detected by the receiver or transmitter’s self-diagnostics, an alarm will sound and
“Power-OFF’ will be activated. Until the malfunction has been corrected, it will be impossible to Power-On
the controller.
(2)
Maintenance Technicians can use the error messages. However, we recommend the technician replace only
the module. The defective module should be returned to our distributor for component-level repair. This will
eliminate further damage to the controller.
(3)
If you do not understand the error message from the transmitter or receiver, or the signal is not listed in this
manual, please contact our distributor for clarification and advice.
