6  Initial Start-up Setting 1. When setting up DT3 for the first time, press key for more than 3 seconds till the screen display and select according to your temperature sensor type. Please be aware that a selection of wrong model would cause PV temperature display error . (Ref er to the chart below) 2. When setting up the temperature sensor typ[...]

7 For example: Measure V alue=25.0; Compensation = 1.2. Af ter applying to the Compensation equation PV=26.2. ¾ Linear Compensation Gain (setti ng range = 0~0.999). Linea r Compensation Gain Calcul ation equation: PV = Measure V alue* (1 + Gain/1.000) + Compensation. For example: Measure V alue=25. 0; Gain= 0.100. After applying to the Gain calcul[...]

9 O u t p u t o f when in PID control mode (Ctrl= PID): When the controller is in PID control and dual loop output mode, sets the P value of the 2nd set of PID. The 1st set of PID is generated when TUNE= AT, but user can also manually sets the PI D value. The P value of th 2nd set of PID = the P value of 1s t set of PID x . The I and D value of the[...]

10 If the setting control is in running mode, the program will st ar t running from the initial pattern and initial step, and carry out commands one by one. When the setting control is in end mode, the program will stop running and give out an output disable. When setting control is in stop control and temperature is cont rolled at the setting valu[...]

12 c 、 Coef and DeadB and are added in the PID parameter for double out put (one for heating and one for c ooling). Coef refers to the ratio between the first and second portions of output (P parameter of second group =Coef*P , Coef= 0.01~99.99); DeadBand is the overlapping temperature of the P output of the first group an d the second group. ¾ [...]

13 Auto Fine-tune the PID value. During the calculation, A T LED li ghts up in the display panel. When the PV value generates 2 curv es of temperature oscillation based on the SV value, the A T process is completed and the A T LED in the panel goes out. The calculated PID parameters are displayed in , , , and , of which their content can be revised[...]

14  EVENT Function This controller provides a maximum of 3 EVENT s (EV1~EV3) for respectively setting EV functions as shown in the following T able <1>. For example, if EV1 is used for Run/S top selection, when the c ontroller is set to RUN status, if terminals in the Option1 slot are open, the controller is in RUN status; if terminals in [...]
