Temperature Controllers E5CSV 5
1. Sensor Type Specification
Multi-input (Thermocouple/Platinum
Resistance Thermometer) Models
• Using Thermocouple Sensors, Control Mode Switch 5: OFF
• The control range is -20° C to +20° C of the input temperature
range.
Note: 1. The input indication range is the range that can be displayed for
the control range (-99 to 1999). If the input is within the control
range but exceeds the display range (-99 to 1999), values below
-99 will be displayed as “[[[“ and values above 1,999 will be
displayed as “]]].”
2. If unit is changed to 1 degree when the SP and alarm value for
the temperature range are displayed in 0.1-units from 0.0 to
199.9 or 0.0 to 99.9, the values will be multiplied by 10 (e.g., 0.5
becomes 5). If the unit is changed in the reverse direction, the
values will be divided by 10. After changing the range, set the
SP and alarm value again.
• Using Platinum Resistance Thermometers,
Control Mode Switch 5: ON
• The control range is -20° C to +20° C of the input temperature
range.
Note: 1. The input indication range is the range that can be displayed for
the control range (-99 to 1999). If the input is within the control
range but exceeds the display range (-99 to 1999), values below
-99 will be displayed as “[[[“ and values above 1,999 will be
displayed as “]]].”
2. If unit is changed to 1 degree when the SP and alarm value for
the temperature range are displayed in 0.1-units from 0.0 to
199.9 or 0.0 to 99.9, the values will be multiplied by 10 (e.g., 0.5
becomes 5). If the unit is changed in the reverse direction, the
values will be divided by 10. After changing the range, set the
SP and alarm value again.

Mode Key Display Order
• If the SP falls outside the temperature
range when the temperature range is
changed, the SP will be displayed first.
The SP will be changed automatically
either to the minimum value or the
maximum value, whichever is nearest.
• If the alarm value falls outside the
temperature range when the
temperature range is changed, the
alarm value will be displayed first. The
alarm value will be changed
automatically to the maximum value in
the new temperature range.

ST (self-tuning) is a function that finds PID constants by using step
response tuning (SRT) when Controller operation begins or when
the set point is changed. Once the PID constants have been
calculated, ST is not executed when the next control operation is
started as long as the set point remains unchanged. When the ST
function is in operation, be sure to turn ON the power supply of the
load connected to the control output simultaneously with or before
starting Controller operation.
AT (auto-tuning) is executed by pressing the U Up and D Down
Keys for at least 2 s while the PV is displayed. The deviation
indicators flash during auto-tuning (AT) execution. AT will be
cancelled by performing the same operation that AT is executing
during AT operation. Flashing stops when AT is completed.
Note: One of the deviation indicators (▲■▼) will flash.
