Operation
NOTICE:
Always turn off the power supply to the Electronic Temperature Controller before changing any switch settings.
Settings
1. Remove the internal mechanism from the housing. Lift the internal mechanism while pressing the hook at the bottom of the front panel. Protection switch (SW101, PROTECT)
Hook Pull out the internal mechanism while holding down the hook with your finger. 2. Four internal switches must be set on the E5AX: the temperature sensor selector, the operating mode selector, and the alarm mode selectors 1 and 2. The figures show the locations of these switches and the protection switches on the internal mechanisms. The protection switch can be used to disable key operation.

E5AX-P Key Protection Switch (SW101, PROTECT)
E5AX-P
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).

E5AX-P Inputting Parameters
E5AX-P
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 automatically 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. The display level mode changes as shown below.

Alarm: al 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 produced and the ALM indicator on the front panel lights. Usually, the alarm value is set as a deviation from the main setting, but it can also be set as an absolute value when the event alarm mode is selected. Set the alarm value by using the Up and Down Keys while al is displayed. The message is not displayed if the alarm mode selector is set to position 0. Factory-set to upper-limit, alarm value 0%C/%F Input Shift: in-5 When pin 3 of the operating mode selector switch (SW201) is set to the ON position, the input shift function can be used. This function is used to shift the temperature display from the measured value by a desired value, as shown by the examples in the following table: Input shift value 0 (without shift) 10 (shifted by 10%C) -10 (shifted by -10%C) Temperature measured by sensor 100%C 100%C 100%C Displayed temperature 100%C 110%C 90%C

Basically, the temperature range that can be measured is determined by the temperature sensor to be used. For example, when a K-type (chromel-alumel thermocouple) temperature sensor is selected, the measurable range is from -200%C to 1,300%C. However, this temperature range can be narrowed, for example, to 0%C to 400%C. To do this, set the lower-limit value of the temperature setting range, in this case to 0%C, on the SV display by using the Up and Down Keys while 5l-l is displayed on the PV display. Similarly, set the upper-limit value, 400%C, while 5l-h is displayed. If the process temperature falls below the set lower-limit value or exceeds the set upper-limit value, it is displayed on the PV display within the temperature range of the temperature sensor. Hysteresis Alarm: hysa The hysteresis alarm value for the alarm can be set in a range from 0.0% to 999.9%C while hysa is displayed on the PV display using the Up and Down Keys. The factory setting is 0.2%C/%F. Disable band: db The disable band can be set in a range from 0.1% to 10.0% while db is displayed on the PV display using Up and Down Keys. The factory setting is 2.0%. Motor Calibration: calb Designate whether or not to perform motor calibration. To enter the mode, simultaneously press the Up and Down Keys for at least one second. Press the Display Key to return to sl-l.

E5AX-P 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. Previous PID constants Main setting

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 auto-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 temperature of the controlled system reaches the set temperature. After that, the Temperature Controller automatically adjusts the PID constants using the limit cycle method. When the auto-tuning indicator turns off, the auto-tuning is terminated and PID constants are renewed.
AT indicator flashes Limit Cycle Method: the optimum PID constants are calculated by this method by varing the control output variable and generating external oscillation. Auto-tuning can be carried out regardless of whether the Temperature 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 return to those prior to the beginning of auto-tuning. Automatic tuning can be executed at any time: at power application, while the temperature is rising, or after the control action has stabilized.
Error Messages

Potentiometer input (see Note 1) Use these terminals when connecting a thermocouple (do not remove short bar from terminals 14 and 15).
Note:
1. Connect a valve position indicator if required. 2. Do not connect unused terminals.

Precautions
Mounting
The dimensions of the Temperature Controller conform to DIN 43700. Recommended panel thickness is 1 to 8 mm. Do not install the Temperature Controller in a location exposed to excessive dust or corrosive gases. Moreover, avoid locations subject to heavy vibration or shock, water or oil spray, or high temperatures. Any of these condition will affect product life. Isolate the Temperature Controller from equipment that generates strong, high-frequency noises such as high-frequency welders, because such equipment may prevent proper operation. Attach the two mounting brackets supplied with E5AX on the top and bottom of the Temperature Controller. Tighten the screws of the mounting brackets with your fingers.

Stickers Inside Frontcover
Stickers indicating the temperature sensor type (R, S, K, J, T, E, L, and U) are supplied with the Temperature Controller. Attach the proper stickers to the front panel as shown below.

Connection Examples
With Solderless Terminal Use M3.5 solderless terminals with the Temperature Controller's M3.5 self-rising pressure plate screws. Solder-dipped Leads Strip 6 to 12 mm of the lead wires and carefully arrange the wire tips. Do not tighten the terminal screw with excessive force, because doing so may damage them. The terminal block of the Temperature Controller is constructed so that the lead wires can be connected to all the terminals from the same direction. Top

Input Connection
To reduce inductive noise influence, the lead wires connecting the input to the Temperature Controller must be separated from the power lines and load lines. Use the specified compensating conductors for thermocouples. When using a thermocouple as the temperature sensor, attach the short-circuit bar shown in the terminal block diagram on the housing. Use lead wires having a small resistance for temperature resistance thermometers. Be sure to remove the short-circuit bar from the terminals when a temperature resistance thermometer is used. Sequenced Circuits Several seconds are required until the relay in turned ON after power has been supplied to the Temperature Controller. Therefore, take this time delay into consideration when designing sequenced circuits which incorporate a Temperature Controller.
