3 ALARM1 LOW: Lower limit alarm 1 (display according to the setting in ALARM mode) 4.0 ALARM2 HIGH: Upper limit alarm 2 (display according to the setting in ALARM mode) 4.0 ALARM2 LOW: Lower limit alarm 2 (display according to the setting in ALARM mode) 4.
4 ALARM mode) ALARM3 DELAY: Set up Alarm 3 delay (refer to “Alarm Outputs” ) (display when OUT2 is set to ALARM mode) 0 PV Color Change Function: Select the alarm to change PV display color.
5 SV SLOPE: Set up rising slope (when CRTS = SLOP) ANALOG OUT1 MAX.: Adjust upper limit compensation for analog Output 1 (1scale = 1 μ A; 1scale = 1mV) 0 ANALOG OUT1 MIN.: Adjust lower limit compensation for analog Output 1* (1 scale = 1 μ A; 1scal e = 1mV) 0 ANALOG OUT2 MAX.
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 .
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.
8 ¾ T o set Retransmission to positive/negative slopes (a Retransmission board must be installed first): In 【 Initial Setting Mode 】 set the parameter , the last digit (Y) of xxxY indica tes when Y =0 positive slope; when Y=1 negative slope.
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.
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.
11 ¾ Remote compensation adjustment: input corresponding lower limit of analog signal at the Remote end, set Remote compensation adjustment by parameter in 【 Regulation Mode 】 ¾ Remote gain adju.
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.
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.
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>.

16 screen . If the password is incorrect, the screen will return to PV/SV display mode. 3. Enter the new password two times in the screen. The screen w ill return to PV/SV display mode with the ke ys unlocked. If the two entries of password are not the same, the screen will go back to the state of step 2.
17 17 When HOLD status happens to PI D program control, alarm output is ON. 18 When STOP status happens to PID prog ram control, alarm output is ON. 19 When END status happens to PID progra m control, alarm output is ON. ¾ T o set Alarm Mode: Use the parameters , , in 【 Initial Setting Mode 】 to select the alarm mode.
