Red LED is ON.
(Diagnosis is
activated)
Analogue input device
power supply is
short-circuited.
Check the parts with error by using the LED display or
unit diagnostic data
or master. Re-wire the
short-circuited part, and check if the cable and analogue
input device are normal.
"0 and 1" red
LEDs are ON.
Input value has exceeded
the upper limit when set to
current input type range.
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.
Red LED is
flashing.
(Diagnosis is
activated)
(1)Input value has
exceeded the upper or
lower limit of the range.
(2)Input value (value set by
user) has exceeded the
upper or lower limit.
(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.
