1. Why do we use auto tuning device
We choose PID process control in most occasions while temperature control is highly required. There are different parameters for different temperature control objects, such as proportional band, differential time, and integral time. Traditional PID devices, the above functions are set by experienced experts, so the parameters are very likely to mismatched, consequently the whole system is easily go beyond control. It brings many troubles to our customers. But for this series of device, it hasnʼt had these troubles, because it carries auto tuning function. While start the function, it will analogue experts to operate, make it attain perfect effect.
2. How to use auto tuning
(1). Press SET to enter into the second setting area, and then enter into auto tune setting situation according to the operation processes. Press SET for 5 seconds after set" AT "as "01", then the device will logout from setting situation and enter into auto tuning condition, and here the AT lamp flashes. It will auto tuned after controlling for three cycles (time are different in terms of lengths), then "AT" indicator lamp goes off and the PID parameters will saved automatically.
(2). You can go over in the second setting area if you want to check PID parameters.
(3). The power supply should be work well and should reduce interferences as much as possible while in the process of auto tuning; otherwise it will need to start again.
(4). Parameters may different between start the auto tuning at the beginning and at the controlling point, but generally the second parameters are preferred.
(5) Reset repeatedly to check these parameters after auto tuning in great interference occasions, then choose to revise.
