E001
Memory Error
RX
The memory contents were
destroyed.
Turn the power OFF and ON. If a
memory error occurs again, send
Initialize Setting Data (MC) and
Memory Write (WE) in this order
and turn the power OFF and ON
again. If a memory error still
occurs, the memory needs repairs.
E002
Sensor Input AD Error
RX
The sensor AD converter circuitry
failed.
Turn the power OFF and ON. If a
sensor input AD error occurs
again, the sensor AD converter cir-
cuitry needs repairs.
E003
Cold Junction Compen-
sation Error
RX
The ambient operating tempera-
ture is -15
°
C or less, or 60
°
C or
more.
Use the E5ZE at an ambient oper-
ating temperature of -15
°
to 60
°
C.
E004
CT Input AD Error
RZ
The CT input AD converter circuitry
failed.
Turn the power OFF and ON. If a
CT input AD error occurs again,
the CT input AD converter circuitry
needs repairs.
E011
Sensor Error
RX
The wires of a temperature sensor
connected to the E5ZE are burn-
out, shorted, or incorrectly wired.
Make sure that the wires of the
temperature sensor are not burn-
out, shorted, or incorrectly wired.
E012
Upper Limit Error
RX
The process value at the desig-
nated control point was 20
°
C/40
°
F
or more than the set point upper
limit value.
Use the E5ZE so that the process
value will not exceed the upper
limit.
E013
Lower Limit Error
RX
The process value at the desig-
nated control point was 20
°
C/40
°
F
or less than the set point lower limit
value.
Use the E5ZE so that the process
value will not be less than the lower
limit.
E022
Heater Current Upper
Limit Error
RZ
The process heater current value
at the designated control point was
55.0 A or more.
The E5ZE cannot measure a
heater current value of 55.0 A or
more.
M001
Temperature Control
Interrupted
Rs
The temperature control operation
of the designated control point is
stopped.
The ramp function does not oper-
ate and reading is not possible
while operational control is
stopped.
