Current Transformer Input AD Error
This error occurs if the IC that converts CT input values to the E5ZE to digital
values fails or a peripheral circuit of the IC fails.
Cold Junction Compensation Error
This error occurs in the following cases if the E5ZE is a thermocouple input
model.
• The Cold Junction Compensator is not connected to the terminal block cor-
rectly.
• The terminals screws of the Cold Junction Compensator is loosened.
• The Cold Junction Compensator is broken.
•
The ambient temperature drops below -15
°
C or exceeds 60
°
C.
Setting Data Error
This error occurs in the following cases. If a setting data error occurs, initialize
the parameters with Initialize Setting Data (MC) within the permissible param-
eter setting ranges of the E5ZE.
• Setting data in the memory are destroyed.
• A set point of a control point is not within the allowable set point range.
CPU Error
This error occurs if the CPU or its peripheral circuitry is broken.
Reset the set point in the following cases.
•
°
C is changed to
°
F or vice versa with the FUNCTION switch.
• The input type connected to a control point is changed with the INPUT
