7-2 Error Displays
Errors That Stop the Output (Alarm Level 1)
Display Error name Probable cause Countermeasures
e01
RAM Error Error in the internal memory or
nonvolatile memory Turn ON the power again. If this does not remove
the error, the operation of the Power Controller must
be checked by OMRON.
e02
EEPROM Checksum
Error (Calibration Value
Error/Illegal Identifica-
tion Code)
e03
EEPROM Checksum
Error (Set Value) Error in the set values in the
nonvolatile memory Move to the initial setting level and initialize the set
values. If this does not remove the error, the opera-
tion of the Power Controller must be checked by
OMRON.
e04
EEPROM Checksum
Error (Total Run Time) Error in the total run time in the
nonvolatile memory Move to the initial setting level and initialize the total
run time. If this does not remove the error, the oper-
ation of the Power Controller must be checked by
OMRON.
e10
SSR Short-Circuit The SSR is short-circuited or
the heater is totally burned out. Check that the heater is not burned out. Turn ON the
power again. If this does not remove the error, the
operation of the Power Controller must be checked
by OMRON.
e11
SSR Open Failure An SSR open failure occurred
or the heater is not connected
to terminal T1 on the load termi-
nal block. Check whether the heater is connected to terminal
T1 on the load terminal block. If this does not
remove the error, the operation of the Power Con-
troller must be checked by OMRON.
e12
CT Failure The built-in CT Unit has failed or
the heater elements are all
burned out. Check that the heater is not burned out. Turn ON the
power again. If this does not remove the error, the
operation of the Power Controller must be checked
by OMRON.
e20
Heater Overcurrent
Error An overcurrent was detected. An overcurrent is flowing to the heater. Check the
load and use the alarm reset (see note) to clear the
error.
e30
Zero Cross Error A zero cross error or frequency
error was detected. Check whether the load power supply voltage and
the frequency are within the specified ranges.
Check whether noise is occurring in the load power
supply line or in the surroundings.
Use the alarm reset (see note) to clear the error.
e31
Frequency Error
e40
Heater Burnout Alarm A heater burnout was detected. Refer to 5-9 Heater Burnout Detection, check for
burnout, and check the set values. Use the alarm
reset (see note) to clear the error.
e50
External Input Range
Alarm A disconnected line was
detected for the 4 to 20-mA or 1
to 5-V input signal input or
external variable resistor. A disconnected line was detected for the 4 to 20-mA
or 1 to 5-V input signal input or external variable
resistor. Check the location of the disconnection.
If the 4 to 20-mA or 1 to 5-V input signal input and
external variable resistor are not being used, refer to
the auxiliary input-related parameters and make the
setting.
Use the alarm reset (see note) to clear the error.
e51
External Duty Input
Alarm External duty input disconnec-
tion A disconnected line was detected for the external
duty variable resistor.
Check the location of the disconnection.
If the external duty variable resistor is not being
used, set the External Duty Input Enable/Disable
parameter [P01] to Disable.
Use the alarm reset (see note) to clear the error.
