Bit Meanings in Detail
Meanings of other bits have been described previously.
Bit 0: RUN Status
Indicates the following operation control status of the E5ZE.
• Temperature control or manual operation
• OFF
Bit 1: Control Mode
Indicates the control mode of the E5ZE.
•
2
-
PID control mode (with ON/OFF control)
• Manual operation mode
Bit 2: Output Operation
Indicates the control output operation of the E5ZE.
• Direct operation
• Reverse operation
Bit 3: Memory Write
Indicates the existence or nonexistence of the setting data of the E5ZE.
• Not written
• Written
Bit 4: Auto
-
tuning
Indicates the auto
-
tuning status of the E5ZE.
•
Auto
-
tuning
•
Not auto
-
tuning.
Bit 7: Heater Current Overflow
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.
Bit 8: Process Value Underflow
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.
Bit 9: Process Value Overflow
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.
Bit 10: Sensor Input Error
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
