Troubleshooting
Check the parts with error by using the LED display or
∗
master or H.T. Re-wire the short-circuited part, and
check if the cable and analogue input device are normal.
Check the following when the range of the Analogue
input unit is set to current input.
(1)Set the input value of the analogue input device so
that it does not exceed the upper limit.
(2)Voltage is input from the analogue input
device.Ensure the range of the Analogue input unit
matches the range of the analogue input device.
(1)If the input value from the analogue input device
exceeds the upper or lower limit of the range, select
the appropriate range so that the input value is within
the range. Or invalidate diagnosis.
(2)If the input value from the analogue input device
exceeds the upper or lower limit of the user set value,
adjust it so that the input value is within the range of
the user set value. Or invalidate diagnosis.
Stop the operation and contact SMC.
