To change the mode to set or change a different group of parameters, hold down the Level Key for 2 seconds minimum. Actual displays vary with models and switch settings. Do not connect unused terminals. Hold down the Level Key again for 2 seconds minimum to display o on the PV display.

Press the Display Key to return to sl—l. The factory setting is seconds. Integral Time Reset Time: The factory setting is 40 seconds.

The message is not displayed if the alarm mode selector is set to position 0. Always turn off the power supply to the Electronic Temperature Controller before changing any switch settings.

The factory setting is 2. Level Key Press for 2 seconds minimum to change levels to omrln different groups of parameters. When the auto-tuning oron turns off, the auto-tuning is terminated and PID constants are renewed. Note 3 al 0 Alarm value Press a.

Be sure to remove the short-circuit bar from the terminals when a temperature resistance thermometer is used. Successively decreases the value when held down. Set the alarm value by using the Up and Down Keys while al is displayed.


When the Level Key is pressed for 2 seconds minimum after power application, 5l—l is displayed on the PV display. Alarm modes, listed in the following table, can be selected using this switch.


Press the Display Key. Displayed only when the motor calibration mode is entered. Always switch to the manual output mode before changing the proportional band.

HEA In the interest of omrpn improvement, specifications are subject to change without notice.

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: Connect a valve position indicator if required. Valve Travel The value travel can be monitored. The count value for the fully close position will be set. This DIP switch selects the operation modes listed in the following table.

AT indicator flashes Limit Cycle Method: Refer to temperature range charts under Ordering Information for further information. Main setting, set alarm value Write disabled Read from Temperature Controller Main setting, set alarm value, proportional band, integral time, derivative time, set limit value, process value, valve position, error codes, etc. Any of these condition will affect product life.

After that, the Temperature Controller automatically adjusts the PID constants using the limit cycle method. A maximum of 32 Temperature Controllers can be connected to one host computer using serial communications RS, RS All settings will return to those prior to the beginning of auto-tuning. Level 2 In level 2, selected input sensor, and modes for alarm output can be monitored.

Main setting, set alarm value, process value, error codes, etc.

Optimum PID control with feed-forward control circuitry. Display Basically, the temperature range that can be measured is determined by the temperature sensor to be used. Make sure that control operations have been stopped before calibrating. RS and terminals are shown.

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. Then, selected input sensor, and alarm modes can be monitored each time the Display Key is pressed. Displayed temperature 0 without shift Lower setting limit Press a.

Four internal switches must be set on the E5AX: Process value a 0 Note 2 Valve travel Press a. To convert millimeters into inches, multiply by 0. Automatic Output Mode In automatic output mode, the control will function automatically.

Input shift value — fr—l Count value Fully closed position Press a. Solder-dipped Leads Strip 6 to 12 mm of the lead wires and carefully arrange the wire tips.

It is factory-set to position 2 to designate a K-type chromel-alumel thermocouple temperature sensor.

To convert grams into ounces, multiply by 0. The count value for the fully open position will be set. When using a thermocouple as the temperature sensor, attach the short-circuit bar shown in the terminal block diagram on the housing. Set value coincides with the indicated value, because no relative omroon exists between both values.
