Connect a valve position indicator if required. Automatic tuning can be executed at any time: Motor calibration will be displayed when power is turned on for the first time. HEA In the interest of product improvement, specifications are subject to change without notice.

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. Therefore, take this time delay into consideration when designing sequenced circuits which incorporate a Temperature Controller.

Main setting, set alarm value Write disabled Read from Temperature Controller Main setting, set alarm value, proportional band, integral time, lmron time, set limit value, process value, valve position, error codes, etc.

After that, the Temperature Controller automatically adjusts the PID constants using the limit cycle method. 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: While auto-tuning is in operation, the auto-tuning indicator on the front panel will flash.

Ormon not tighten the terminal screw with excessive force, because doing so may damage them. Simultaneously press the Up and Down Keys for at least one second. Alarm Mode Selector SW Note that level 2 is a monitoring level only and thus no parameters can be changed. Use the specified compensating conductors for thermocouples. Manual Output Mode Indicator Lights when in manual output mode.


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. Tighten the screws of the mounting brackets with your fingers. Press the Display Key to return to sl—l. Front Cover Down Key Press e5xx decrease the main setting or other parameters.

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. Press the Level Key for at least omrkn seconds, confirm that in—t is displayed, and then press the Level Key again for at least two seconds to display the process value and return to the initial display mode.

Up Key Press to increase the main setting or other parameters. Select this function by pressing the Display Key three times in display level 0.

If this difference is too great, a drastic change will result. When using a thermocouple as the temperature sensor, attach the short-circuit bar shown in the terminal block diagram on e5qx housing.

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. ON Sends alarm signal in accordance with the set alarm mode. Always set the following parameters e5qx installing the controller.

High precision regardless of the set temperature. When the Level Key is pressed for 2 seconds minimum after power application, 5l—l is displayed on the PV display.

Main setting, set alarm value, process value, error codes, etc. E5xx count value for the fully open position will be set. The following table shows the messages that may be displayed. It can be set in a range from 0 to 3, seconds in units of 1 second. Integral Time Reset Time: Level Key Press for 2 seconds minimum to change levels to set different groups of parameters.

Not displayed when the alarm is disabled SW set to 0 or 9. The platinum resistance thermometer has burned out or A and B terminals have been short-circuited. If a display is required for valve position, set the open and close positions at the same time.

Temperature Controller must be repaired if recovery is not made by turning power off once and on again. Proportional alarm output is OFF, however.

Displayed only when the motor calibration mode is entered. Alarm hysteresis db Proportional Band: Optimum PID control with feed-forward control circuitry.

Be sure to remove the short-circuit bar from the terminals when a temperature resistance thermometer is used. All units are in millimeters unless otherwise indicated. Pmron value see note 3valve position 1. The factory setting is The maximum total cable length must not exceed the following limits. Process value a 0 Note 2 Valve travel Press a.
