The bits shown in the table below are set to 1 when a heater burnout alarm oc-
curs.
Wd (n+8), bit 02
Wd (n+9), bit 02
Use one of the methods below to reset a heater burnout alarm.
Turn ON the Special I/O Unit Restart Bit (AR 0100 to AR 0109 for the C200HX/
HG/HE, C200HS, C200H and A50200 to A50209 for the CS1) and then turn it
OFF.
Turn the PC power supply OFF then back ON.
Set the heater burnout current limit to 00 then back to its original value.

EEPROM Control output:
error The transistor output or
voltage output is OFF or the
current output is less than
2 mA.
Alarm output is OFF.
The RUN indicator turns off when an EEPROM error occurs.
The unit number duplicates the number of another Special I/O Unit. SR 25415
(for C200HX/HG/HE, C200HS, C200H) or A40113 (for CS1) will turn ON when
an Duplicate I/O Unit error occurs. Refer to AR0000 to AR0009 for the C200HX/
HG/HE, C200HS, C200H or to A41100 to A41109 for the CS1 for the duplicated
unit number. The CPU Unit will not operate during a duplicate I/O error.
Set the Unit number to a separate number.
I/O refresh not operating correctly between the CPU Unit and Temperature Con-
trol Unit. Operation is not interrupted when a Special I/O Unit error occurs. Refer
to AR 0000 to AR 0009 for the C200HX/HG/HE, C200HS, C200H or to A41100 to
A41109 for CS1 for the unit number where the error occurred. After correcting
the cause of the error, turn ON the Special I/O Unit Restart Bit (AR 0100 to
AR0109 for the C200HX/HG/HE, C200HS, C200H; A50200 to A50209 for the
CS1) to restart operation.
The PC power supply is turned on but the RUN indicator is not lit. None of the
errors described previously are detected. Replace the Unit.
No 24 VDC power supply is connected to the Temperature Control Unit input ter-
minals A8 and A9.
