Error Detection
When an error occurs in an input or in the Unit, details of the error are output to
the Data Setting Console and input relays (words n+8 and n+9).
Sensor Input Errors
The following table shows the Data Setting Console display and error contents.
Display Error name Output status after
error
Cause Remedy
ser1 Loop 1 sensor error
Control output:
The transistor output or
voltage output turns OFF
or the current output falls
below 2 mA.
Alarm output:
The alarm is output
Reading is
±
10%FS out
of sensor measurement
range (i.e., 10%FS
below the lower limit or
10%FS above the upper
limit).
Broken or incorrect input
Check the sensor wiring.
Replace the sensor.
Replace the Unit.
Correctly set switch
SW203-4.
ser2
Loop 2 sensor error
The alarm is out ut
assuming the input is
±
10%FS.
Broken or incorrect in ut
wiring
Defective input sensor
Defective Unit
SW203-4 is OFF (Loop
2 enabled) but no sensor
connected to Loop 2.
Data Setting Console When a sensor error occurs, one of the codes above and the detected value are
displayed alternately.
If a Loop 1 sensor error
ser1
and a Loop 2 sensor error
ser2
occur simultaneously,
ser1
is displayed preferentially. Even if a sensor error is detected in one Loop, the
other Loop continues to operate normally. Control operation restarts automati-
cally five seconds after the cause of the error is corrected.
The following bits are set when a sensor input error occurs.
Loop 1 sensor error Wd. n+8, bit 14 = 1
Loop 2 sensor error Wd. n+9, bit 14 = 1
Alarm
Display Error name Cause Remedy
ALM1
indicator lit Alarm 1 The value is in the
alarm range set with
Alarm SV 1.
Check the object
being controlled.
ALM2
indicator lit Alarm 2 The value is in the
alarm range set with
Alarm SV 2.
Error displayed when an abnormality occurs in the loop currently being dis-
played. No indicator is provided to show an ALM2 alarm.
The bits shown in the table below are set to 1 when an alarm occurs.
Wd (n+8) Bit 01 = 1 Alarm 1 Loop 1
Bit 00 = 1 Alarm 2
Wd (n+9) Bit 01 = 1 Alarm 1 Loop 2
Bit 00 = 1 Alarm 2
