*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.

**SP protection cancel is effective only when SW101 (key protec-
tion) is on. If the SP protection cancel is ON, key protection (SW101
ON) will not apply to the set point, i.e., you will be able to change the
set point regardless of the setting of SW101.
Alarm Mode Selector (SW205: ALM)
Alarm mode selector is provided on all E5AX Temperature Controllers. Alarm modes, listed in the following table, can be selected using this
switch. The switch is factory-set to position 2, i.e., the upper-limit alarm mode.

Starting Control Operation
The E5AX will start control operations as soon as power is turned on
until power is turned off. If you don’t want control operations to be
performed while setting parameters, turn off the power and then turn
it back on after setting the desired parameters.
Main setting
Previous PID
constants
New PID constants
Auto-tuning
When the Level Key and Mode Key are pressed at the same time for
1 second minimum, the Temperature Controller automatically starts
tuning the PID constants. While auto-tuning is in operation, the au-
to-tuning indicator on the front panel will flash. The Temperature
Controller executes control based on the set PID constants (factory
set to P = 40%C, I = 240 seconds, and D = 40 seconds) until the tem-
perature of the controlled system reaches the set temperature. After
that, the Temperature Controller automatically adjusts the PID con-
stants using the limit cycle method. When the auto-tuning indicator
turns off, the auto-tuning is terminated and PID constants are re-
newed.
Error Messages
AT indicator flashes
Limit Cycle Method: the optimum PID constants are calculated by
this method by varing the control output variable and generating ex-
ternal oscillation.
Auto-tuning can be carried out regardless of whether the Tempera-
ture Controller is performing reverse (heating) or normal (cooling)
operation. To stop auto-tuning, hold down the Level Key and Mode
Key again simultaneously for 1 second minimum. All settings will re-
turn to those prior to the beginning of auto-tuning. Automatic tuning
can be executed at any time: at power application, while the temper-
ature is rising, or after the control action has stabilized.
The Temperature Controller is provided with self-diagnostic functions, and will display an error message on the PV display when an error is
detected.
