Temperature Controller
A 96 x 96 mm (DIN) Controller for
Control Valves
Controls motor valves without a potentiometer.
Optimum PID control with feed-forward control
circuitry.
High precision regardless of the set temperature.
Compatible with various inputs (input selected via
internal switch).

*The Controller can also be equipped with a terminal block to connect communications. Specify a terminal block by adding "-X" to the model
number. Example: E5AX-PRR02-X
**Capable of transmitting the process value or output value, but remote setting by external input is not possible.

FUNCTION) The scale displayed (%C or %F) is selected by the operating mode This DIP switch selects the operation modes listed in the following selector (SW201).
  • Page 6 E5AX-P E5AX-P Key Protection Switch (SW101, PROTECT) When the key protection switch is set to the ON position, the Level Key, Up and Down Keys, and Auto-tuning Key cannot be operated. In effect, the Temperature Controller is write-protected and the set values (such as the alarm value) can be read out only. The set point, however, will not be protected if the SP protection disable is turned ON (pin 4 of SW201).
  • Page 7 E5AX-P E5AX-P Motor Calibration: calb The following setting are used to set the opening/closing time for controlling valves. Always set the following parameters when installing the controller. If a display is required for valve position, set the open and close positions at the same time. Down Keys to set the fully open/close time to a value between 1 and 999 s in the units of 1 s.
  • Page 8 E5AX-P E5AX-P Inputting Parameters The Temperature Controller has three display levels, 0, 1, and 2, in which only specific parameters can be set. Level 0 is the initial and is auto- matically entered at power application. To change the mode to set or change a different group of parameters, hold down the Level Key for 2 seconds minimum.
  • Page 9 E5AX-P E5AX-P Alarm: al Level 1 When al is displayed on the PV display, the alarm value for alarm output can be set on the SV display. When the temperature exceeds or falls below the set alarm value, the corresponding alarm output is sl–l produced and the ALM indicator on the front panel lights.
