Temperature Controller Topic: RUN/STOP Function

FAQ No. FAQ00657

Question

What is the Run/Stop function? Also, please tell me how to set it on the E5[]N.

Answer

1. What Is the Run/Stop Function?

• This function is used to designate “run” or “stop” in the Operation Level.
• When “run” is selected, the Temperature Controller operates, and when “stop” is selected, it stops. When the Temperature Controller is stopped, the STOP indicator will light.
• This function is used, for example, when it is necessary to temporarily stop the Temperature Controller during system maintenance.
• Even when this function is set to “stop,” however, functions other than the control outputs (such as alarms) are output exactly as they are set.
• The default setting is “run.”

<<Precautions»

• The Run/Stop function can also be set for an event input.
• When set for an event input, the Run/Stop setting cannot be changed using the front keys. (Also, in this case, the "r-s" parameter will not be displayed.)

2. Setting the RUN/STOP Function

2-1. After turning ON the power and confirming that the Operation Level is being displayed, press the Mode Key several times to display the Run/Stop parameter. (See Figure 1.)

When "run" is displayed at the bottom of the display, the Temperature Controller will operate.

When "stop" is displayed at the bottom of the display, the Temperature Controller operation will be stopped.

Press Mode Key for several times. You will see the RUN/STOP parameter.

2-2. Press the Up/Down Keys to switch the setting to “Run” or “Stop” (Figure 2).

<<Precautions»

If the power is turned OFF immediately after changing the setting, the change will not take effect. Either wait for about 2 seconds after making the change, or press the Mode Key to enter the change.

2-3. Press the Mode Key several times to return to the present value/target value display.

• When the parameter is set to “Run,” the Temperature Controller will output exactly as set, displaying "OUT1" when OUT1 is ON, and "OUT2" when OUT2 is ON.
• When the parameter is set to “Stop,” the Temperature Controller will stop operating, and "STOP" will be displayed as the operation.

<<Precautions»

1. When the parameter is set to “Run,” and control output 1 is a current output, "OUT1" will remain OFF.
2. When the parameter is set to “Stop,” all functions (such as alarms) other than control output will output as set.

Please tell me of any precautions for extending the lead wires of a Temperature Sensor.

There seems to be a large error in the temperature of the Temperature Controller. Why?
