Heater burnout
The detected heater
current is below the
heater burnout current
value.
Check the heater
and heater wiring.
Replace heater if
necessary.
Error displayed when an abnormality occurs in the loop currently being dis-
played.
The following bits are set when a heater burnout alarm occurs.
Wd (n+8), bit 02 = 1
Loop 1 heater burnout alarm
Wd (n+9), bit 02 = 1
Loop 2 heater burnout alarm
Use one of the methods below to reset a heater burnout alarm.
a) Turn the Special I/O Unit restart flag (AR0100 to AR0109) ON and then
back OFF.
b) Turn the C200H power supply OFF then back ON.
c) Set the heater burnout current limit to 00 then back to its original value.

Temperature alarm 2
The temperature is in
the alarm range set
with Alarm 2 SV.
“ALM1” displays the temperature alarm 1 for the loop current selected. No indi-
cator is provided to show an ALM2 alarm.
The bits shown in the table below are set to 1 when a temperature alarm occurs.

Replace
the Unit
The RUN indicator turns off when an EEPROM error occurs.
Duplicate I/O Unit
The Unit number duplicates the number of another Special I/O Unit. The SR bit
25415 turns ON when an Duplicate I/O Unit error occurs. Refer to AR0000 to
AR0011 for the duplicated Unit number. The C200H PC will not operate during a
duplicate I/O error.
Set the Unit number to a separate number.
Special I/O Unit Error
I/O refresh not operating correctly between the CPU Unit and Temperature Con-
trol Unit. The Heat/Cool Temperature Control Unit is operating based on the con-
