4.FRONT PANEL AND OPERATION
Basal display status: When power on, the upper display window of the instrument shows the process value (PV), and the lower window shows the set point (SV). This status is called basal display status. When the input signal is out of the measurable range (for example, the thermocouple or RTD circuit is break, or input specification sets wrong), the upper display window will alternately display “orAL” and the high limit or the low limit of PV, and the instrument will automatically stop output.
Artificial Intelligence control and auto tuning
When A18 control method is chosen, the control parameters can be obtained by running auto-tuning. At the first time of running auto-tuning, in basic display status, press“<<" for 2 seconds, “At” will flash at lower display window and the instrument executes on-off control. After 2 to 3 cycles of on-off action, the instrument will obtain the values of PID control parameters. If you want to escape from auto tuning status, press“<<" and hold for about 2 seconds until the "At" flash stops. Depending on the system, the time of auto tuning can be several seconds to several hours. After the auto tuning finishes, the parameter “CTRL” automatically changes to 3 (the initial value is 1) or 4, and then user can’t active auto tuning by pressing “<<" for 2 seconds. If user wants to run auto tuning again, setting parameter "CTRL” to 2. (Refer to the description of parameter “CTRL”)
Note 1: Before running auto-tuning, set point should be set to an often-used value or middle value first, and then start auto-tuning. Generally, for application with 10%~80% time on heating can obtain satisfying auto-tuning result. If the heating time is not in the range of 10~80%, the auto-tuning will run for a long time and can’t get satisfying result.
Raising set point for heating time less than 10% or decreasing set point for heating time greater than 80% can improve auto-tuning result
Note 2: Don’t modify the set point during auto-tuning. It may affect the precision of auto-tuning.
Note 3: After auto-tuning finishes, generally, the temperature rising has a little over-shoot (about 1~3 ). It is because °C considering that the transducer is often placed between the heater and heated material, and a little over-shoot can shorten the time of rising to set point and save Power. (Generally, the temperature of transducer can be raised quickly than that of heated material)
