Indicates the following operation control status of the E5ZE.
• Temperature control or manual operation
• OFF
Indicates the control mode of the E5ZE.
• 2 - PID control mode (with ON/OFF control)
• Manual operation mode
Indicates the control output operation of the E5ZE.
• Direct operation
• Reverse operation
Indicates the existence or nonexistence of the setting data of the E5ZE.
• Not written
• Written
Indicates the auto - tuning status of the E5ZE.
• Auto - tuning
• Not auto - tuning.
This flag turns ON to indicate that the measured heater current has exceeded
55.0 A. The E5ZE continues temperature control even when this flag turns
ON.
This flag turns ON to indicate that the process value at a control point has
dropped below the set point range by 20 C or 40 F or more. The E5ZE contin-
ues temperature control even when this flag turns ON.
This flag turns ON to indicate that the process value at a control point has
exceeded the set point range by 20 C or 40 F. The E5ZE continues tempera-
ture control even when this flag turns ON.
This flag turns ON to indicate that the sensor connected to a control point has
been incorrectly wired, that the sensor circuit is burnout, or that a temperature
input from the sensor has exceeded the set point range. Although the E5ZE
