Heater Current Monitor (Display Level 1)
PV
SV
Heater current monitor parameter symbol
Currently set heater current value. Units: Amperes (A).
If the current exceeds 5.5 A, a CT Input Overflow error
occurs and
ffff
is displayed.
Input Shift Value (Display Level 0)
PV
SV
Input shift value parameter symbol
Currently set input shift value. Units:
°
C or
°
F. The setting can
be changed from this display.
If the displayed temperature value differs from the actual temperature value due
to the sensor position or some other conditions, set the input shift value such that
the correct temperature is displayed.
Control Period (Display Level 1)
PV
SV
Control period parameter symbol
Currently set control period. Units: Seconds (s). The set-
ting can be changed from this display.
The control period is the time required to complete one transistor output or volt-
age output ON/OFF cycle.
ON time
Control period

Control Output Variable Monitor (Display Level 2)
PV
SV
Control output variable monitor parameter symbol
Current control output variable. Units: percentage (%).
The relationship between the control output variable and control period is de-
fined by the formula below:
Control output variable (%) = x 100
ON time
Control period
The control output variable during ON/OFF control (when SW203-1 on the rear
panel is ON) is ON = 100% and OFF = 0%.
Hysteresis (Display Level 1)
PV
SV
Hysteresis parameter symbol
Currently set hysteresis value. Units:
°
C or
°
F. The
setting can be changed from this display.
