The following table shows the messages that may be displayed: Display 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. WARNING Never calibrate the motor during control operation.

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 New PID constants Main setting 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 The Temperature Controller is provided with self-diagnostic functions, and will display an error message on the PV display when an error is detected. Message Cause Control output Normal Alarm output Reverse ffff Input temperature has exceeded the upper limit of the temperature range by more than 20%C.

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 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. Mounting bracket Sticker identifying input type 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 Bottom 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. 13 E5AX-P E5AX-P ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
